kexec is now fully working!
Kexec host kernel: https://github.com/willcast/ubuntu-kernel-tenderloin branch is "kexec"
Graphical bootloader: https://github.com/willcast/kexecboot
Compiled host kernel uImage UPDATED: https://docs.google.com/file/d/0B4WUjKii92l2RHJoNE93c2dVRlU/edit?usp=sharing
THE ATTACHED KERNEL PATCH (decomp_copy_atags.diff) _MUST_ BE APPLIED for ANY kernel to be bootable FROM kexec.

Kexec kernel and OS installation is best performed through SmackMe2, which is available in its own thread on this site.
I have no idea what you are saying, but keep up the great work!
Keep up the good work man , one question with you work in the future can we delete web os from the touchpad forever?
I imagine that's already possible. Use lvm to delete all the logical volumes not tied to another OS and then delete the uImage.webOS symlink. That deletes webOS, frees mostof its space and removes it from the moboot menu.
If you choose to do that, though, using the doctor to restore WEBOS will be even more difficult because you'll have to wipe out everything AND potentially need to "unbrick" your TP (using the method involving NovaCom, the small boot image ripped from the doctor and a string of LVM commands that is posted on sone or other forum.)
Lvm? Can you make a tutorial? How to remove webos from touchpad?
Thank you
Before this is complete or posted for testing, I think we will need a tutorial and links to files of how to fix the tp from a full brick such as issues with removing and restoring webos.
Great job if your boot loader works as planned we will have a full multi-boot device with a few restrictions(drivers for untested ports, etc).
Keep it up.

Awesome that you're resuming development castrwilliam! Can't help you with kexec though, sorry. I hang around in the Motorola Defy forums and some developers like Quarx have tried pursuing the kexec route in order to load custom kernels onto the Defy, might be worthwhile to throw him a PM. Would be great to have a more flexible bootloader!
I anyone needs a full restore, this thread helped me out. I followed the instructions when I screwed up and doctored without removing partitions. I believe WebOS Doctor handles repartitioning, so it should work:

WORKING (but non-Kexec) Android multiboot for TouchPad.
DON'T TRY ANYTHING UNTIL YOU HAVE READ THE WHOLE POST!!
Beta 2 Updated with support for my Froyo Qcom kang.
I created a script that can install multiple versions of Android on the HP Touchpad, side by side, such that they can be selected at the MoBoot menu and operate independently. The script modifies them, on the Touchpad itself, to work with the new names for the partitions.
I want your feedback on this installer. It is used in the same way as ACME Installer but only shares one line of actual code with it (and it also uses the same binaries and config files on the initial ramdisk image, but they are Open Source so that should'nt matter.) I'll be posting this on XDA in a minute, my username there is also "castrwilliam".
If you do choose to use (TEST!) this:
- You need to create a folder on your media partition (the one that is shown when you select USB mode) with the following zips:
moboot [moboot_0.3.5.zip]
(the rest are optional but I recommend using them all so that you can help me test everything)
Froyo Test [Froyo-2.2.1-Qcom-Kang-Touchpad-a0.1-incl-gapps.zip]
CM7 alpha3.5 [update-cm-7.1.0-tenderloin-a3.5-fullofbugs.zip]
CM9 latest nightly [cm-9-xxxxxxxx-NIGHTLY-tenderloin.zip]
CM10 latest preview [cm-10-xxxxxxxx-EXPERIMENTAL-tenderloin-FOR_LIMITED_TESTING_ONLY_CAM.zip]
2.3.x gapps [gapps-gb-xxxxxxxx.zip]
4.0.x gapps [gapps-ics-xxxxxxxx.zip]
4.1.x gapps [gapps-jb-xxxxxxxx.zip] MAKE SURE not to use 4.2 gapps!
(NO Android Recovery will work yet, so don't try. It will reject TWRP and CWM at least.)
- If you already have Android and/or Moboot and/or native Linux (Ubuntu, etc.) installed:
* back up any data on your media volume. webOS should back up your apps for you.
* make both a nandroid (which WON'T work to restore in a multiboot config, but if you go back to single boot, it will be fine) and a Titanium backup [which should be portable to the same OS.]
* run ACMEUninstaller and then run SmackMe-Installer.
* if you have native Linux, backup your /etc and /home (I recommend the lovely GNU tar and gzip/bzip2). That should be the majority of what to keep.
* ALSO uninstall any native Linux you may be using after you back it up.
* lastly unzip and novacom boot the SmackMe-Installer.
If you don't already have Android, MoBoot OR native Linux, just:
* back up any data on your media volume. webOS should back up your apps for you.
* then unzip and novacom boot the SmackMe-Installer.

File should be attached. Report bugs by PM'ing me, or posting in this thread
Can i remove webos with this multiboot? And stay only on android and ubuntu?
This is strictly an installer. I was going to write a webOS removal script. However, android doesn't have the needed binaries. That leaves me two options: make another thing like SmackMe to do it or do it under whatever version of native Ubuntu you are running. Either way, I really don't want to have to test it myself. If I need to I'll have to doctor my touchpad EVERY TIME I do it. That's a lot of doctoring and a lot of flash write wear. So the answer is basically "find me a dev that wants to remove webos too. They'll either make you one or beta test mine." Sorry man.
Amazing keep up the good work castrwilliam !
Strange request
Hey, does anyone here still have the 2011 Froyo (2.2.1) system dump for Touchpad? It wasn't CM6, just something that HP accidentally released and someone over at Rootzwiki dumped. I'm posting this here because I have no account and they'd think I'm a noob there. All the links are down to it and I want to try messing around with its files, just for kicks. Maaaaybe I can get it to boot, and add support for it to the SmackMe installer, so at least I can have *four* versions of Android on my touchpad.
http://forum.xda-developers.com/showthread.php?t=1234381
You know, 'cause I'm just that crazy.
Wow it's been hard to find it but i think this is the good dump:
http://download.digiex.net/Consoles/Tablets/HP-Touchpad-Android2.2.1-Disk-Images.zip
sources:
http://digiex.net/downloads/downloa...hpad-android-2-2-1-system-image-download.html
it's alive! (sorta)
Somebody on XDA found a link that I thought was dead. It was the mmc dump of someone who had Froyo leaked by HP onto their fire-sale Touchpad.
FAQ:
"Obviously nobody wants this. Everybody's running Jelly Bean."
That's exectly why I did it. My point is to do the most outrageous and downright unnecessary things possible with commonplace hardware.
"What doesn't work?"
Rotation, sound, wi-fi, softkeys (i.e. Home, Back, Menu, Search.)
"What does work?"
Camera (OH HAYULL YA), touchscreen, battery reading, power button, volume button (but it dosen't matter b/c sound is borked).
"I can haz Modded Froyo?!"
Not yet.
YouTube: http://www.youtube.com/watch?v=zX29IcTIB14
Hah awesome work, I think you hold the record of most different OS'es on one device now! It looks quite functional already.
Oh and about the "Obviously nobody wants this. Everybody's running Jelly Bean." quote, I only run WebOS and your Ubuntu 12.10 port on the TP!
As soon as I get my power button sorted out I am on this!

Hey everyone! Froyo here!
I've just zipped up my Froyo kang such that it will work if flashed from SmackMe, and if you're crazy enough to run it alone, hopefully also Android recovery.
sound works!!
The Wi-Fi works now BUT YOU NEED A STATIC IP ADDRESS. (problems with dhcpcd)
The buttons are hacked to work (by my new shell script: /system/bin/buttond, check it out) as follows:
Volume Down is Back
Volume Up is Menu
Center is Home.
Obviously once the audio works (if ever) that will be an issue. My embarrassing secret (at least probably to the devs here) is that I don't know Java. That makes it difficult to mod on any touchscreen buttons...
The real audio library is /system/lib/libaudioflinger.real.so and the stub one (default via a symlink) is /system/lib/audioflinger.so. Using the real one causes bootloops.
Auto rotation still won't function.
Google Apps and even Facebook are included in this ROM. (It's not CM6.) So are some potentially geeky Qualcomm apps.
Don't set up your Google Account during first boot, because it will ask you to slide the keyboard open. That sounds pretty impossible onn this device. Set it up from Settings later, and you shouldn't have that issue.
UPDATED due to install issues with actual Android Recovery. Redownload.

I wanted to try froyo soo bad when I heard about those dumps last year (I think) lol. I still want to try it.
Now, if I read correctly, I can flash this from TWRP/CWM right?

It should work from that. I only tried with my SmackMeInstaller from the last page. That said... MAKE A NANDROID, because it WILL delete your current Android install, and if anything goes wrong (or even if it works but you see a CWM/TWRP error/warning), tell me and I'll fix it.

Important notes
- YOU DIRTY FLASH AT YOUR OWN RISK.
- FULL WIPE IS ALWAYS SUGGESTED WHEN FLASHING NEW VERSION.
- DON'T EXPECT A BUGLESS EXPERIENCE IF YOU DIRTY FLASH OR USE TITANIUM BACKUP.
ArchiDroid 3.1 is major new release based on CyanogenMod 12.1 (Android 5.1.1 Lollipop). There are too many changes compared to previous release of AD 3.0.2, so you should treat this version as totally new ROM. Here you can find some important notes to make update easier, and to avoid some possible issues:
- If coming from AD 3.0.2 or any other ROM, regardless what it is, you should make full wipe. ArchiDroid is smart enough to detect itself during install and offer you an update, but this option should not be used with major release such as this one. Full wipe in necessary.
- It also means that you should AVOID restoring old, incompatible data with apps such as Titanium Backup. Full wipe means full wipe, not half wipe and restoring data later. Of course, it's up to you if you want to follow my suggestions or not, but do not expect that you'll have bugfree experience otherwise.
- You should update your recovery prior to flashing, again, regardless of what recovery you have now. The best way is to do so right from ArchiDroid ZIP, as AD offers updating recovery prior to flashing the rest, from AROMA. On the preset screen you can choose "Recovery" to update to latest (confirmed working) TWRP for i9300, reboot recovery and flash the rest. Only TWRP is supported by me, AD should be universal enough to be flashed with other recoveries as well but you're on your own doing so.
- While not mandatory, I suggest also a wipe of whole internal SD card (/data and /data/media), as this will make sure than no junk is left. If you don't want to do so, at least make sure to remove /data/media/0/ArchiDroid folder prior to flashing, even if you have experimental AD 3.1 already. I do not track all regressions and doing so will make sure that backend works in intended way. A best way to do so is to update your recovery first, then through TWRP file manager navigate to /data/media/0 and remove whole ArchiDroid folder.
- AD already has built-in GAPPS, provided by OpenGApps project. Flashing other GAPPS is not recommended, but if you know what you're doing you can still untick all Google Apps offered in AROMA (Whole GAPPS category including core gapps + also google launcher and google keyboard) and install your own GAPPS package after AD installation. Although, as I said, I suggest to stick with AD gapps, as they're proven to be working well, and they're tested by me and other experimental users.
TL;DR
- Make full wipe
- Update recovery prior to flashing
- Wipe internal storage, or at least remove /data/media/0/ArchiDroid
- Flash AD
- Do not restore old data through titanium backup
- Enjoy your fresh ArchiDroid experience

[SIZE="+1"]Features / Why ArchiDroid?[/SIZE]
First of all, ArchiDroid includes everything available in it's base. The whole point of ArchiDroid is to improve the base, without needing of making any trade-offs, so by flashing ArchiDroid, you're getting everything offered by the base itself. There's nothing to lose, everything to gain.
You can read detailed information about every ArchiDroid component here. It's a massive wall of text, so I'm only going to list the core features without describing them.
These were written from scratch, they're completely unique and you won't find exactly the same implementation in any other ROM.
ArchiDroid-Unique features:
- ArchiDroid's AROMA Installer
- ArchiDroid's Pocket Debian
- ArchiDroid's Flasher
- ArchiDroid's RunOnce
- ArchiDroid's Init
- ArchiDroid's Backend Control
- ArchiDroid's HArdware Volatile Entropy Gathering and Expansion Daemon (Haveged)
- ArchiDroid's Fast Random Number Generator (Frandom)
- ArchiDroid's Adblock (dnsmasq/dnrd, dnsproxy2, pixelserv)
- ArchiDroid's Forced Update
Apart from that, here, on the credits page, you can find all third-party projects, which have been implemented into ArchiDroid. In addition to that, it's up to YOU to decide if you want to install something, or not.
ArchiDroid focuses on flexibility and user choice.
If you're looking for fastest ROM, choose ArchiDroid.
If you're looking for most battery-saving ROM, choose ArchiDroid
If you're looking for cutting-edge functions, choose ArchiDroid
If you're looking for the most flexible rom ever created, definitely choose ArchiDroid
ArchiDroid adjusts to your needs. You can make it whatever you want. With bunch of presets, modes and questions, you can make your ArchiDroid behave. Check yourself why ArchiDroid is The TOP 1 ROM for Galaxy S3http://forum.xda-developers.com/galaxy-s3#romList, according to number of followers, rates, reviews and downloads count. Check the Reviews, take a look at Video Reviews, do whatever you want to, ArchiDroid is proven to be one of the best ROMs for Galaxy S3, ever created.
Try ArchiDroid once, and you'll never look back. I can assure you.

ArchiDroid is one of the most complex ROMs ever created. When you start digging in my work, you can very easily get lost. And I'm not talking about base itself, but about everything next to it. You can use every part of my work, as long as:
1. You include proper credit where you should. This usually includes proper comment in a script/file and in the credits of the project, including license (if needed)
2. You let me know about this fact. Through PM on xda or e-mail
I'm always happy to help, especially with the problems I faced in the past. However I also want to be respected, considering that most of the ArchiDroid parts were written from scratch.
ArchiDroid 2.X vs. ArchiDroid 1.X
The long battle between choosing over ArchiDroid 2.X and 1.X is still recent. There's no one real and true answer to this. It's up to YOU to decide who wins this battle, because obviously every user is different. I'm only going to give you some tips and briefly describe differences.
Despite the name, ArchiDroid 2.X and 1.X are totally different ROMs. It all started with ArchiDroid 1.X, a ROM based on Sammy's stock firmware, with all needed goodies and features baked in. Then eventually I managed to implement everything what I ever wanted to implement, therefore making ArchiDroid 1.X more or less complete. Then I started with ArchiDroid 2.X project, built from scratch from AOSP sources, with all source codes available.
The point is, ArchiDroid 1.X is more or less complete, there's no "real" development going on, as I obviously don't have samsung sources to begin fun with. On the other hand, ArchiDroid 2.X will never be finished, there's always something to improve, something to add, something to fix... This is ongoing process, which will reach the end when I finally break my SGS3 or change the phone to another one .
If you're new user or you don't know how AOSP works on our SGS3s then I highly suggest to flash ArchiDroid 1.X firstly. ArchiDroid 2.X is targeted at advanced users, who don't mind some "core" features being broken. It will NEVER be as stable as ArchiDroid 1.X is, so if stability is the number 1 for you, choose 1.X.
ArchiDroid comparision
From 1-10, based on my own point of view
Stability
2.X - 5
1.X - 8
Compatibility
2.X - 4
1.X - 9
Battery
2.X - 6
1.X - 9
Performance
2.X - 9
1.X - 6
Features
2.X - 9
1.X - 4
Android Updates
2.X - 9
1.X - 6
-----------
Overall
2.X - 42
1.X - 42
This is ArchiDroid comparision in a nutshell. If you ask me, I think that ArchiDroid 1.X is far better choice for daily driver, but if you're advanced user and you know how to deal with possible broken functions then you can have great time using ArchiDroid 2.X as well.
Remember that only ArchiDroid 1.X supports Samsungs-specific features, such as Smart Stay, Screen mirroring, Allshare or whatever. This also includes closed-source proprietary drivers, such as many bluetooth headsets, which won't work under open-source AOSP. Think twice before considering 2.X if you're addicted to these Samsung goodies.
On the other hand, ArchiDroid 2.X is the only ArchiDroid with "real" development going on, however all universal changes are also backported back to ArchiDroid 1.X, so you're not missing any feature, which benefits also Sammy's base.
That's it. I hope that a choice between both of these awesome roms is a bit easier now. If you still can't decide I suggest to flash both of them for some time and then decide which suits you better.
Know Your ArchiDroid
ArchiDroid is not only a rom. It's not only a baked android with third-party apps, modifications and tweaks. ArchiDroid is an universal backend which improves rom by many built-in functions.
Let me tell you a story. During developing first version of ArchiDroid 2.0 I experienced many problems, which were not that easy to solve. First of all - apps data. Trust me or not but you can't simply extract data, put it in /data/data after install and hope that it works. Android will detect such injection, report inconsistent of data and wipe everything attached to that. Okay so... How I should provide you with my boeffla preset? CoolTool settings? STweaks profile? If I put my data during flashing it'll get wiped. If I put my data and deny wiping it then Android will report inconsistent of data to user and work unstable. Yes guys, it's impossible to do so without a trick or without recompiling whole rom.
I won't tell you a whole story, because you probably don't want to hear about ArchiDroid development. I'll simply tell you that I overcome MANY difficulties, simply because I do what I like, and I like what I do. After countless number of hours, I can finally provide you with the ROM, which is the best. Why is it the best? Because I'm improving the base, and I'm not making any trade-offs.
GitHub / Versioning / Experimental Versions
ArchiDroid version contains 3 numbers. X.Y.Z. X is the base number of the rom. For now it won't change because ArchiDroid 1 is based on Sammy Rom and ArchiDroid 2 is based on CyanogenMod. Basically we have two numbers left, Y and Z. Y number will change when I'll implement something really new, when I'll make some advanced improvements or after many Z changes. Z number is the "standard" update, like updated sources, some bugfixes and so on.
I've learned many things since releasing of first ArchiDroid 1.0.0. Because of that I've also created a GitHub repository, which you can find here. What does it mean for you? First of all as you can see there are 4 different branches. 1.X-STABLE, 1.X-EXPERIMENTAL, 2.X-STABLE and 2.X-EXPERIMENTAL. What does it mean? You can enter selected branch and click on "Commits" button to see every single update which I've made to selected branch. Experimental branches will get updates nearly every single day, especially 2.X-EXPERIMENTAL because of many CM changes and updates. Additionally after some tests I'll merge current 2.X-EXPERIMENTAL into 2.X-STABLE every week and provide as "weekly update", of course if current experimental will be stable enough to do so.
However that doesn't mean you need to wait for my updates! You can easily "pack" latest experimental and flash without needing to wait for my weekly build. I'll tell you how to download and flash it by yourself.
You can see differences between current stable and experimental here.
[Newbie Version]
1. Open 2.X-EXPERIMENTAL branch.
2. Click on Download Zip button located in bottom-right corner.
3. Install 7-Zip if you don't have that already. Other programs may, or may not work correctly.
4. Right-Click on zip, select Extract Here
5. Navigate to newly created ArchiDroid-2.X-EXPERIMENTAL folder
6. Select all files WITHOUT __dont_include folder, right-click and select 7-Zip => Add to archive
7. Make sure that you have zip format, Fastest compression (to save some megabytes) and Deflate method of compression.
8. Voila, copy newly created ArchiDroid-2.X-EXPERIMENTAL.zip to your phone and flash as usual.
[Expert Version]
1. Install Git for Windows or Linux
2. If you're on windows then make sure that windows won't change LF into CRLF (git config --global core.autocrlf false)
3. Clone my git repository using .git file. Keep in mind to specify depth, as this repo is really big. (git clone https://github.com/JustArchi/ArchiDroid.git --branch 2.X-EXPERIMENTAL --depth 1)
4. Select all files WITHOUT __dont_include folder zip them into standard .zip format with Deflate compression or without any compression.
5. Copy .zip to your phone and flash as usual
6. In order to update your local repo execute git pull origin 2.X-EXPERIMENTAL and go to point 4.
Additionally you can watch my short video, which shows how to flash experimental ArchiDroid going through "Expert Version".

Introduction / Basics
Welcome to ArchiDroid's world mortal. In this tutorial we will show you what ArchiDroid has "inside" and what it really offers. All of things included in this post are ArchiDroid-specific, which means that you won't find any ROM with the same features, as they're written from scratch.
Here you can find some definitions of the words used in sections below. You should know most of them, but in case somebody is lost here you can get back on track.
Terminal, Shell - Typical android shell, which may be obtained in three ways.
1. Through native Android Debug Bridge (ADB) with command "adb shell" from the PC or even "ADB through network" (if supported).
2. Through any Android terminal app, f.e. Android Terminal Emulator bundled with ArchiDroid.
3. Through secure shell daemon (sshd), which needs to be turned on firstly. This is extremely useful in terms of pocket debian, which will be described later.
You can use any of these methods to access android's terminal, however usually Android Terminal Emulator will be the easiest one, as it's android app bundled with ArchiDroid. WARNING! Most of the commands below WILL require root access. You can log in to super user shell by "su" command right after obtaining shell. If you're unsure if you're logged as root or not, "whoami" command should print actual user, "root" or "unknown uid 0" are OK, others are not.
ArchiDroid's Pocket Debian
From wikipedia:
Debian is an operating system composed of free software mostly carrying the GNU General Public License. The operating system is developed by an internet collaboration of volunteers aligned with The Debian Project.

From debian site:
As most of you know, Linux is just a kernel. And, for a long time, the Linux kernel ran only on the Intel x86 series of machines, from the 386 up.
However, this is no longer true, by any means. The Linux kernel has now been ported to a large, and growing, list of architectures. Following close behind, we have ported the Debian distribution to these architectures. In general, this is a process with a sticky start (as we get libc and the dynamic linker working smoothly), and then a relatively routine, if lengthy job, of attempting to recompile all our packages under the new architectures.
Debian is an operating system (OS), not a kernel (actually, it is more than an OS since it includes thousands of application programs)

How exactly this covers our beloved SGS3 (and countless number of other android arm-based phones)?
As you may (or even should!) know, Android operates on it's own Linux-based kernel. Android's kernel is literally a fork of Linux kernel, with a few special/unique functions which are required, mostly hardware-specific. Because of that kernel itself is VERY compatible with everything based on Linux.
However there have always existed one typical problem, lack of proper environment. We have a great kernel, great power, linux-based android environment, but this environment lacks of very common and required libraries/binaries. If you ever wondered what is or what does busybox, this is the answer. Busybox is just a small package which offers a few standalone GNU/Linux binaries, which are required to make certain things work. For example, swap priorities. Android knows what swap is, and nothing else. It doesn't know that swap could have a priority, so if you use android's swapon command on 4 devices, it will firstly fill first device, and then proceed to the next. That's why we need busybox in ALL custom kernels, because android environment isn't enough.
However busybox sometimes isn't enough. If we focus only on Android itself, it is. But if you for example want to run stricly linux-based service, I don't know, a web server for example... Is it possible to run a native linux web server on an android? No, it's not. You should firstly compile such service on arm architecture, including all dynamic and static libraries (wrrr ) in it only to finally get mad because of missing libraries or other dependencies. Of course if you're patient you'd finally compile everything and set up, however how long would it take? A few days maybe? If you're skilled in what you're doing...
This is why I included built-in "pocket" debian in ArchiDroid. It's FULLY compatible with everything compiled/based on armhf/armel GNU/Linux architecture, for example Raspberry Pi. With two easy commands you can literally jump into debian environment and use every typical GNU/Linux utilities known from debian itself. Of course this means nothing for most of the users, because they'll never have any reason to use such debian environment but from the developer side, it's big step forward. The best example is with github. As you know ArchiDroid has it's own repo on github, from where you can download/manage stuff. There also exists git app for linux and windows. If you want to follow "expert" way of flashing experimental ArchiDroid version, such program is required. The scenario is the same as compiling web server for an android, it requires much more effort than it's worth. And even then you can end up with syncing external dependencies and searching for solutions for the problems you've never seen before... And with ArchiDroid's pocket debian? It's as simple as in any debian/ubuntu distro. "apt-get update && apt-get install git" and voila. Your git is installed and ready for work. Going further I've even included git in pocket debian itself. Okay, I have debian, I have git, and what next? With git utility I can for example provide you with delta updates for ArchiDroid! ArchiDroid can easily use pocket debian to set up and sync ArchiDroid's repository and then pack and flash latest version without even needing of a PC, using 7-zip or anything else. Another example? A web server. I know that it's very dev-specific but if you for any reason need a web server running, just for example to test simple website, you can have it with just one command. Going further, VNC? MySQL server? PHP? Python? Perl? Ruby? Maybe conditional tasks with cron? Persistent minimal IRC client? rtorrent with rutorrent GUI over WWW? The list goes on... Anything based on linux will work. You can even host a server for your favourite game, as long as it has armhf/armel binaries (unfortunately most of the games don't).
So that's it. In short, debian is an operating system built-in in ArchiDroid to provide you with (unfortunately missing) GNU/Linux environment, with full power, ready to handle anything you could request. I made my best to include fully working debian in ArchiDroid for a minimal cost. Whole OS is packed in one big tar file, compressed using highest bzip2. As for now pocket debian has ONLY 40 megabytes of size, maybe in future it will have up to 50 megabytes, but no more. It's a VERY small cost for having such great power, especially if you know how to use it.
This is a really cutting-edge feature, mostly because I have no limitiations what I can include in my ROM right now, and while other developers are dealing with OpenDelta updates and many Android-based problems, I'm just launching my pocket debian and manages linux stuff.
I'm SURE that most of the advanced ArchiDroid user will just LOVE this feature, as much as I love it. I'm looking forward to your responses how YOU use pocket debian with your ArchiDroid. It's also a great time to learn what does the debian offer and how you can simplify your common tasks with just one example debian utility .
Technical informations:
1. Pocket Debian does not cause any additional overhead. We don't need to use emulation, neither virtualization to boot our monster. I used chroot technology to "jump" into debian environment with already running kernel and Android. That means additional required CPU/RAM is based on what you run in pocket debian. Booting itself doesn't require anything, just about one megabyte of ram for /bin/bash shell .
2. Android has some restrictions, mostly sockets. It doesn't allow to create inet sockets by default, even for root users. You will need to add your custom debian users to special group called "inet" (GID 3003) to allow creating of inet sockets, and you may also need to add a group to net_raw group (GID 3004) to allow creating of raw sockets. Please keep in mind that it's only required if you're running an app which required it's own socket, for example mysql server. So apt-get install mysql-server will fail right after booting, you will need to use "addgroup mysql inet" and then apt-get -f install to complete installation. Of course "mysql" is the new user under which mysql-server really operates. I've added root to both of these groups by default.
3. The only "real" restriction is the kernel. Our debian uses Android kernel and it's filesystem. It should work with most common tasks but in some cases our kernel may lack specific modules or built-in code, for example tun/tap required for OpenVPN. Still it's enough to run pretty much everything and if you get in touch with your favourite kernel developer you can also kindly ask for specific missing things.
4. Debian is built and included thanks to debootstrap utility, ArchiDroid command used for creating debian environment is debootstrap --verbose --arch armhf --include=git,ca-certificates,ssh,htop,tightvncserver,xterm,xfonts-base --exclude=manpages,man-db,rsyslog,vim-common,vim-tiny testing debian http://ftp.fr.debian.org/debian
HowTo:
Pocket Debian contains two main terminal commands, "adlinux" and "debian". Both of them are described below. By adlinux and debian you boot and jump into debian's chroot, which means you can use any debian-specific commands.
Examples:
passwd - changes password of actual user. This is needed to login as specific user, for example through ssh.
service ssh start - starts local SSH (secure shell) daemon on native port :22, to which you can easily access via any client supporting ssh, f.e. PuTTY. So basicly after you start shell you can literally connect to your local area network (LAN) IP on port 22 f.e. through PuTTY from your PC.
ifconfig - prints network-related informations about online interfaces, including your local IP, which may be useful for connecting to SSH.
htop - Enhanced top utility. Gives you very good terminal-based view on actual running processes, used ram, load, and more.
apt-get update - Syncs with debian's apt repository. This is mandatory to use many of apt commands because ArchiDroid's debian comes without local repo available, however fully configured to download and access it with just one command
apt-get install XXX - installs packet XXX from debian's repository.
apt-cache search XXX - searches for all packets including keyword "XXX". Ultra useful in terms of searching for specific packet.
Please note that pocket debian is VERY similar to normal native Debian/Ubuntu distribution, therefore above commands are not ArchiDroid's magic, they're very widely used in Debian/Ubuntu distros. If you want to learn more, most of the Debian/Ubuntu tutorials will be very helpful.
ArchiDroid's Pocket Debian Booter (adlinux)
You can call "adlinux" command from your favourite terminal.
adlinux is designed to boot and prepare ArchiDroid's Pocket Debian environment. It requires mode to be specified, and also respects any extra arguments passed.
If you call standalone "adlinux" command then it will print usage and then ask you what you want to do with giving proper informations about every choice. Additionally if you know what you want to do, you can also pass arguments directly to adlinux command, f.e. by executing "adlinux default", which will execute adlinux with "default" mode.
Available modes:
default - Will mount /data /system /storage/sdcard0 /storage/sdcard1 and core filesystems in chroot. Default suggested mode
safe - Will mount only core filesystems in chroot. Useful if you don't want to share your storage in chroot
bare - Won't mount even core filesystems such as /proc /dev or /sys. Requires "debian force" to enter chroot. This is the "real" safe mode. You won't be able to interact with an android in any way, while debian itself will work in very limited environment, making core functions unavailable. Suggested only for testing purposes
rebuild - Will automatically reboot your device and remove debian folder in the safe way. WILL CAUSE ALL DEBIAN DATA TO BE LOST!
unmount - Will automatically reboot your device to safely unmount debian environment
Extra options:
extsd - Use external sd card (/storage/sdcard1 /storage/extSdCard), if possible
intsd - Use internal sd card (/data/media/0)
Additional information about modes:
Debian shares core kernel filesystems in "safe" and "default" modes, while it also shares your internal and external sd card in "default" mode. This is nothing to be scared of, as you have full control of what you run in debian, however please note that you CAN'T do whatever you want. All mounted partitions in debian are "binded". "Bind" means that it's mirrored to the mount point and all changes on mounted partition WILL affect the mount point, which is logical. This is nothing to be scared of, as long as you know that debian only extends your environment, it does not fully works in it's own and you CAN cause serious problems from inside of chroot. The only really safe mode is "bare" mode, however in "bare" mode debian can't really do anything, as kernel filesystems are absolutely required for most of the functions. Okay so, you need to know one thing. If you have booted debian you SHOULD NOT touch debian's folder, which is ArchiDroid/debian (on your internal or external sd card, depends what you choosed).. As you know debian for example binds /data to it's folder /data, which is physically ArchiDroid/debian/data. If you for example delete ArchiDroid/debian through root explorer WITH mounted debian then it will ALSO delete debian/data folder, which is binded to /data, and therefore will delete your whole internal sd card, that's why it's extremely important to take care because booted debian becomes part of the android and deleting it can cause at least soft bricks, with a possibility of hard as well. If you want to delete debian folder PLEASE use "rebuild" mode, only through this way you're absolutely sure that nothing bad happens and you won't delete your whole system partition by accident.
Note about extsd option:
Debian requires symlink functionality, typically native windows filesystems DON'T support symlinks, therefore you need to have your external sd card formatted in one of the native linux filesystems, f.e. ext4. adlinux will automatically tell you if debian can be unpacked and used on your external sd card, however it won't be possible under most common filesystems, such as exFAT or FAT32.
Technical informations:
1. Pocket debian archive is located in ArchiDroid/System/debian.tar.gz file. This is "bare" system used for creating environment for the first time, you should not touch it.
2. adlinux detects if debian is already extracted when booting, if not, it's firstly extracted from the file described above.
3. After extracting (if required), core filesystems are mounted with "bind" option based on the mode you've selected in "mode" question above. Typically it mounts /data /system /storage/sdcard0 /storage/sdcard1 /storage/extSdCard /dev /proc /sys.
4. Unmounting is not fully supported right now (linux barrier), therefore both "unmount" and "rebuild" options require a restart to execute properly.
ArchiDroid's Pocket Debian Shell/Chroot (debian)
You can call "debian" command from your favourite terminal.
debian command is designed to allow you "jumping" into debian chroot created by adlinux. Please read how adlinux command works firstly if you haven't done that already. debian command checks if core filesystems are available (if debian is booted), and if they are then it firstly modifies required environment variables to make debian happy (such as TERM, HOME, PATH), then it changes root (chroots) into debian folder, therefore allowing you to execute everything from inside of chroot. It's very generic command, therefore standalone "debian" command won't give you a choice the way adlinux did.
Available options (parameters):
force - required for jumping into bare debian, created with "adlinux bare" command above. This skips debian checks for mounted core filesystems, normally you should avoid it at all cost, unless you know what you're doing. If core filesystems are missing then it's very likely that your debian will be disabled in more than 90%.
extsd - Use external sd card (/storage/sdcard1 /storage/extSdCard), if possible
intsd - Use internal sd card (/data/media/0)
cmd - Executes command in debian chroot
WARNING! cmd parameter will cause all further parameters to be threated as a command passed to debian, therefore you need to make sure that this is the last debian parameter which you want. For example "debian force cmd service ssh start" will skip filesystems checks and execute "service ssh start" in debian's chroot, however "debian cmd force service ssh start" will pass "force service ssh start" to debian, therefore respecting filesystems checks and passing invalid command.
This function is extremely useful for making init.d and other startup scripts. For example you can easily call "adlinux default" and then "debian cmd service ssh start" to call secure shell daemon on every boot with two easy steps.
Technical informations:
1. debian command uses chroot technology to change root of current shell to debian shell.
2. After chrooting to debian directory, /bin/bash shell is automatically called as default debian shell.
ArchiDroid's Flasher (adflash)
You can call "adflash" command from your favourite terminal.
adflash is a great small utility, which allows you to easily update your ArchiDroid to latest stable or experimental version with one easy command and delta upgrade. It utilizes ArchiDroid functions, therefore you must be running ArchiDroid to use it.
If you call standalone "adflash" command then it will print usage and then ask you what you want to do with giving proper informations about every choice. Additionally if you know what you want to do, you can also pass arguments directly to adflash command, f.e. by executing "adflash 2e git", which will execute adflash with 2.X-EXPERIMENTAL version using git mode.
Available versions:
2e - 2.X-EXPERIMENTAL
2s - 2.X-STABLE
1e - 1.X-EXPERIMENTAL
1s - 1.X-STABLE
Extra options:
git - Sets up local git repository, which gives you delta upgrades and bandwidth saving
direct - Downloads targeted branch as .zip file directly from github
clean - Cleans everything up, including local repo and tmp folder from ArchiDroid directory specified below
extsd - Use external sd card (/storage/sdcard1 /storage/extSdCard)
intsd - Use internal sd card (/data/media/0)
nozip - Shows changelog and changes only
Okay so, the most interesting option is the mode...
Direct mode is simple, fast and effective. It downloads target version (stable or experimental) from GitHub server, then it repacks downloaded zip file and makes it available for flash. You should use this mode for one-time downloads, such as once per stable version or two. The only advantage of this method is the ability to download from github (and with one command).
Git mode is complex. It uses ArchiDroid's Pocket Debian (read above) for cloning and updating local ArchiDroid repo. This gives several number of advantages, mostly for using experimental versions. Firstly, by having local ArchiDroid repo you have to download ONLY changes between your snapshot and server's snapshot, which means delta upgrades. Secondly, you have access to all commits from target branch, so you know exactly what has changed since your latest download. Again, this is extremely useful for experimental branch, as changelog may not be up-to-date. Keep in mind that git mode will require additional space on your device for keeping ArchiDroid repository, therefore you sacrifice some space for delta upgrades. This mode is extremely useful for flashing ArchiDroid often, for example daily experimental versions, because in fact you download only new commits instead of whole repo/archive.
ArchiDroid's RunOnce (Backend)
ArchiDroid's Init (Backend)
ArchiDroid's Backend Control
ArchiDroid Backend Control is a set of settings, which controls behaviour of ArchiDroid's Init. It's located in /system/archidroid/dev and contains a number of files, which are recognized by ArchiDroid's Init. You shouldn't directly touch /system/archidroid/dev, instead you can control behaviour of ArchiDroid's Backend through /system/archidroid/scripts. They can be easily executed through any script manager, f.e. Root Browser or Android Terminal Emulator. Some of the settings are also located in /system/archidroid/etc folder, mostly configurations for binaries utilized by ArchiDroid's Init.
ArchiDroid's HArdware Volatile Entropy Gathering and Expansion Daemon (Haveged)
The haveged project is an attempt to provide an easy-to-use, unpredictable random number generator based upon an adaptation of the HAVEGE algorithm. Haveged was created to remedy low-entropy conditions in the Linux random device that can occur under some workloads, especially on headless servers. Current development of haveged is directed towards improving overall reliablity and adaptability while minimizing the barriers to using haveged for other tasks.
The original HAVEGE research dates back to 2003 and much of the original haveged documentation is now quite dated. Recent work on haveged has included an effort to provide more recent information on the project and its applications.
The original research behind HAVEGE use was based upon studies of the behavior of processor caches from a hardware level. The 'Flutter' documents attempt to provide a modern view of HAVEGE at software level through the use of a diagnostic build of haveged that captures the non deterministic inputs to haveged for analysis by external tools.
ArchiDroid has built-in haveged entropy generator. It's controlable through ArchiDroid's Backend Control - ArchiDroid_Haveged_EnableDisable.sh. It's turned on in default configuration, through HAVEGED_ENABLED
ArchiDroid's Fast Random Number Generator (Frandom)
Frandom is a Linux kernel random number generator, which is 10-50 times faster than what you get from Linux' built-in /dev/urandom. And it uses very little (/dev/frandom) or none (/dev/erandom) of the kernel's entropy pool, so it is very useful for applications that require a handy source for lots of random data.
ArchiDroid has built-in frandom activator. It's controlable through ArchiDroid's Backend Control - ArchiDroid_Frandom_EnableDisable.sh. It's turned on in default configuration, through FRANDOM_ENABLED.
Notice: Kernel must support frandom module to actually make use of that. Init will try to search for frandom.ko module and load it, then use /dev/erandom for both /dev/random and /dev/urandom. If your kernel supports frandom, it will work. If it doesn't, obviously this will be skipped even if you have FRANDOM_ENABLED. Check ArchiDroid Init log located in /data/media/0/ArchiDroid/Init.log to check if frandom works properly for you.
ArchiDroid's Adblock (dnsmasq/dnrd, dnsproxy2, pixelserv)
dnsproxy2 is a replacement DNS proxy for Android 4.3+
This currently allows the user to manually override the DNS server IP,
and it sets the correct UID on outbound requests so they can be filtered
via iptables / AFWall+ / DroidWall / etc.
Dnsmasq is a lightweight server designed to provide DNS, DHCP and TFTP services to a small-scale network. It can serve the names of local machines which are not in the global DNS. The DHCP server integrates with the DNS server and allows machines with DHCP-allocated addresses to appear in the DNS with names configured either in each host or in a central configuration file. Dnsmasq supports static and dynamic DHCP leases and BOOTP for network booting of diskless machines.
Dnrd, Domain Name Relay Daemon is a caching, forwarding DNS proxy server. Most useful on vpn or dialup firewalls but it is also a nice DNS cache for minor networks and workstations.
Pixelserv is a super minimal webserver, it's one and only purpose is serving a 1x1 pixel transparent gif file. Using some creative firewalling (netfilter/iptables) rules you can redirect some webrequests (for adds for example) to pixelserv.
ArchiDroid has built-in Adblock. It's controlable through ArchiDroid's Backend Control:
ArchiDroid_Adblock_DnsmasqDnrdModeSwitch.sh
ArchiDroid_Adblock_EnableDisable.sh
ArchiDroid_Adblock_EnableDisableLocalDNSes.sh
ArchiDroid_Adblock_EnableDisableLocalDNSesDaemon.sh
ArchiDroid_Adblock_LockUnlockHosts.sh
ArchiDroid_Adblock_MoabAdawayHostsSwitch.sh
ArchiDroid_Adblock_Reload.sh
It's turned on in default configuration, through:
ADBLOCK_ENABLED
ADBLOCK_LOCAL_DNSES_DAEMON_ENABLED
ADBLOCK_LOCAL_DNSES_ENABLED
ADBLOCK_USE_ADAWAY_HOSTS
ADBLOCK_USE_DNSMASQ
In short. This is a very advanced and powerful solution for blocking ads through DNS queries. First of all we're forwarding all DNS traffic to localhost (127.0.0.1). Then we're handling them through local DNS server - dnsmasq (default), or dnrd (option). Our local DNS server reads blocked hostnames through special /system/archidroid/etc/hosts file, then if no record is found, it forwards DNS query to OpenDNS/Google DNS servers, or if it's found, returns 127.0.0.1 as the address. Lastly, pixelserv is providing a 1x1 NULLGIF response on local web server, so instead of big black/white screen instead of the AD, we get 1x1 transparent pixel, which usually perfectly hides ad from the app or the website.
Extra features:
1. You can specify if you want to use dnsmasq (default), or dnrd (option) as a local dns server. Dnsmasq is more flexible, modern, faster and has less memory footprint, however I also left dnrd as an option, because it's proven to work stable.
2. You can specify hosts file, which you want to use. In default configuration we use AdAway's hosts file, with more than 30 thousand of records, which results in extra ~2.5 MB memory usage. You have also an option to use MOAB (Mother Of Ad Blocking) hosts file, with more than 330 thousand of records, which will result in about ~30 MB memory usage. Eventually you can append your own rules or use non-standard hosts file, available in /system/archidroid/etc/hosts. Pro tip: You can point AdAway to use this hosts file (/system/archidroid/etc/hosts_adaway), which will result in automatic updates. /system/archidroid/etc/hosts is a symbolic link, either to hosts_away or hosts_moab, if you want to specify your own hosts, you can delete symbolic link and write your own rules.
3. Original /system/etc/hosts file has been locked from editing. This is to ensure that AdAway or other adblockers won't use obsolete and slow method of blocking ads through hosts. The whole point of implementing Adblock in ArchiDroid is to provide you with super-fast, flexible and effective way of blocking ads, also with getting rid of black/white ad screen. In 99% situations you don't want to touch ArchiDroid's default behaviour, as it blocks ads perfectly. Eventually, if you have a very good reason, you can unlock original hosts file through ArchiDroid's Backend Control and modify them, however keep in mind that every additional rule WILL slow down your network speed.
4. In default configuration local dns server uses two OpenDNS servers at port 5353, two Google DNS servers at port 53 and up to two local DNS servers provided by your Wi-Fi/3G connection, which overall gives a sum of 6 remote dns servers. In some rare scenarios (f.e. some wi-fi hotspots) you can notice that a moron, administrator of this wi-fi, blocked all dns queries and forces you to use his DNSes. This is BAD because of freedom and so on, but it's very common practice, that's why I turned on local DNSes as well. If you want to improve your privacy at least a bit, you can disable local DNS servers and then use only OpenDNS and Google DNS.
5. Above option initialy has been written to allow you one-time access to such non-trusty wi-fi's. But if you for any reason need automatic update of your local DNSes (3G and Wi-Fi's will use different local DNSes), you can also turn on Local DNSes Daemon, which will automatically query and update local DNSes if needed. This is also turned on in addition to local dnses above, of course in default preset.
ArchiDroid's Forced Update (RunOnce)
Forced update selected during mode selection in aroma tells RunOnce to work in "INSTALL" mode even on "UPDATE" mode, apart from that it works exactly the same as update mode, only RunOnce is affected.

I'm glad to inform you that I haven't got any call issues since start of developing ArchiDroid 2.0, and that was in May . Of course that doesn't mean that you also won't have such issues but personally I think that you will be satisfied . Check it yourself.
Downloaded & flashed!! First time Aroma hung at 0.00% for about 10 minutes, turned phone off/on & changed some installation settings (not sure if any caused the hang) & the installation was successful. ROM feels silky smooth & looks great!
Will use the ROM for the next few days & see if there are any issues, great so far though.

Downloaded & flashed!! First time Aroma hung at 0.00% for about 10 minutes, turned phone off/on & changed some installation settings (not sure if any caused the hang) & the installation was successful. ROM feels silky smooth & looks great!
Will use the ROM for the next few days & see if there are any issues, great so far though.

Thanks. It looks like latest Aroma 2.70 B6 has some hang issues. That not a problem, simply repeat flashing with any combination you like.
Looking forward to further opinions .
And we have first new experimental already .

If you're interested in flashing ArchiDroid twice per day then take a look at "GitHub" section in the first post :laugh:. Remember that experimental versions won't be released the same way as stable ones.
@Pantherx12
As far as I know Temasek fixed this issue in V104.3, so you can get your fixed ArchiDroid right now .
By far the best I've had so far on your phone.
Great job,thx JustArchi

Looking nice! Makes me happy that it is based on tema's build. Some more flexibility is always welcomed! As about xposed framework. That's a problem. Because it breaks the some framework tweaks tema included after v100. I was using xposed before but there was a much difference with xposed framwork & without. so i removed it.
Plus, What fix tema included in 104.3? A persistent notification one? No, That is still there. Good Luck! :highfive:

Last time I've used xposed it worked fine but if you say so then I'll take a closer look, thanks for reporting.
And about halo fix, I was refering to @Striatum_bdr
It seems halo fix is included in 104.3 built that can be founded in Temasek's experimental built on dev-host only repo.

But if it's not then we need to wait for temasek to fix it . I'm pushing his updates into my experimental branch as soon as possible, sometimes 10 minutes after release

Take a look on the apps openning speed. & alot smoothness without xposed framework. Keep up the good work. I'll soon give it a try! :good:
At the moment I'm updating Q&A, some user signatures and so on.
Also in the meantime I'm testing some new binary files to ensure less problem with aroma freezes. I'm not quite sure if I'm able to do anything with that but at least I'll try . Every approved update will be available in experimental branch of course.
Fixed Halo bug??
NOTE: This is only for Nougat (7.1) custom ROMs (such as Lineage 14.1 based)!
Make sure you do a proper nandroid backup before flashing!
I made a flashable zip for updating the libhoudini stuffs for Nougat (7.1) ROMs to 7.1.0a_y.49344. Not sure if this has been posted elsewhere before, though.
Before flashing, check your current libhoudini version by typing "houdini --version" either from adb shell or from terminal emulator. (UPDATE: Use the built-in Terminal as it doesn't work in Termux)
You should only try to flash this if your houdini version is below 7.1.0a_y.49344. Current custom ROMs usually have a houdini version of 7.1.0_y.48901 (DotOS 1.2 for example).
Flashable zip (It's about 34MB in size) (Dropbox link here)
The original source is from here, apparently taken from Nexus Player (fugu).
After flashing, "houdini --version" should report something like this:
Code:
[14902]
[14902] Houdini version: 7.1.0a_y.49344
[14902]
TESTING NEEDED: I'm not sure what this version of houdini might fix or break, so try this at your own risk. If you're currently not having problems with apps then there's no need to flash this. Compared with existing device files (7.1.0_y.48901, in /system/lib/arm/), several library files are changed, plus an additional "libgate.so" which I could identify it as being an ARM library file (so it'll also be placed in /system/lib/arm, although I'm not sure where it might be used).
EXPERIMENTAL (UNTESTED!): Here's another version in case someone might be interested. This build is 8.0.0_y.49374, and the version number literally means it's to be used for Oreo, so I'm not sure if it'll work on a 7.x ROM. The original source of this version is from Android-x86.
Flashable zip (Dropbox link here)
If the zip works, it should report the following version:
Code:
[19729]
[19729] Houdini version: 8.0.0_y.49374
[19729]
What is the use for this ?

It's just to put updated libhoudini libraries into the device, in hope that those updated stuffs might help with fixing some native libhoudini crashes on certain problematic ARM-only apps.
I had some ARM-only apps that always FC with native crashes (SIGSEGV) from libhoudini on Zenfone 2. Although the updated binaries unfortunately could not fix the problems entirely, at least the they work as intended as I haven't discovered anything broken by the updated stuffs yet.
However, this won't help if your app crash is due to the developer shipping an incomplete set of x86 native binaries (this can happen). You need to sideload it through adb and force it to use ARM abi, like this:
Code:
adb install --abi armeabi xxx.apk
Note that the abi name varies among apps, armeabi is just an example, it might be arm, or armeabi-v7a, depending on the app itself.
EDIT: Say, is there a way to report device incompatibilities to Play Store so I can explain the device's situation and let Play Store always ship the last known good version for our device? There seem to be some apps that previously worked, but not now due to updated native libraries that would cause native crashes on libhoudini (Play Store will still treat our device as compatible due to the device exposing the ARM abis thanks to libhoudini), and I often need to disable the app in question's auto-update to prevent Play Store updating it to the native-crashing version.

Are you using Termux? It seems I'm getting the same result there as well, but houdini outputs just fine in the built-in Terminal as well as in the T-UI launcher.
And as for file lists:
In /system/bin there's the "houdini" binary.
Then there's "libhoudini.so" in /system/lib/ (this is the main library which is of i386 architecture).
And the rest of the files (ARM libraries) in /system/lib/arm/. These consist of the exact same set of files as the ones provided by the custom ROMs, plus an additional one (libgate.so).

I am not sure what is meant by "the built-in Terminal" (I don't recall any ROM coming with one?) but I did use Termux as well as the terminal in TWRP. I figured out if you type "su" to get root access first, then the command works fine in Termux.
Flashed the .zip file. So far, I haven't noticed any changes, good or bad. I don't remember which apps would FC (maybe the Amazon Echo app and Disney Infinity 3.0?) but I'll keep you posted.

Some ROMs do have built-in terminal app. However, you need to enable it, which can be done in Settings -> Developer Options (assuming you know how to enable Developer Options as well). There would be an option to enable "Local terminal" which is the built-in terminal app.
Which means it will help the x86 device run ARM ???
I do not understand. Please analyze me

libhoudini is Intel's ARM binary translator that helps x86 devices run ARM apps, albeit with some limitations and performance reduction due to overhead. Without it, most apps won't be able to work at all, as they don't have x86 native libraries.
Zenfone 2 already has houdini included, that's why it could run as many apps as any other devices. The flashable zip here contains updated files (for 7.1 ROMs) in hope it could help with some problematic ARM-only apps that refuse to work with libhoudini, though in most cases the differences are barely noticeable.

something's wrong I can not download it. I need another link. thank you
My device is running Groovy Android 7.1.1, 18 May Build.
so i have successfully upgraded houdini version using your flashable file. Thank You for your work.
what if i want to revert to the houdini version that comes preinstalled with the rom, will dirty flash rom zip work?

The zip is meant to be flashed every time you reflash the ROM, so yes, dirty flashing should be able to revert it.
But again... you're supposed to do a nandroid backup before flashing, and there's no need to flash this if you aren't encountering any native code crashes from arm-only apps at the moment.
Unfortunately, as Intel had already left the mobile market and no more Intel-powered smartphones produced anymore, some developers started to "move on" and use libraries or compiler options incompatible with houdini in order to make their apps run more efficient on modern ARM smartphones, without having to be "constrained" for compatibility reasons...
The houdini binaries I found only seems to be a minor update, and I'm not sure if Intel is still working on this or if there are possibilities to obtain an even newer houdini version with "y" suffix, which our phone uses.
Added an experimental (UNTESTED!) version found from Android-x86 (8.0.0_y.49374). This version was originally meant for Oreo, so I'm not sure if this would work on a Nougat ROM.
Currently on Android-x86 only the "y" version (which our devices use) is available. The other versions ("x" and "z") are not present, and the link would simply give you a "not found" error.
Although I don't mainly use the phone anymore, I could still conduct some tests with the device if I have time.
Bit the bullet and tested the 8.0.0_y.49374 build. Does not work. Evie force crashes right off the bat. Haven't tested further than this, but if I cannot even use my launcher of choice, that isn't a good sign.
PLEASE BEFORE YOU decide to try this rom, you MUST read all of post 1, 2, 3 and 4 (about 10 minute read). If you think this is an unreasonable request, then stop reading now and find another rom. Thank you.
This is ONLY for the T813. I do not have and will NOT build T713, T719 and T819. See post #2, FAQ 20. Any questions asking to build these will be ignored.
I am not responsible for lost data, identity theft, lost money, security vulnerabilities, bricked devices or any other hardware or software malfunctions that comes as a result of flashing this rom.
BACKUP YOUR DATA AND OLD rom BEFORE trying my rom.
If you are NOT an expert in using fastboot, adb, odin, heimdall, twrp, DO NOT use this rom. You must know how to use these tools to revert back to your old rom. If you are new to flashing custom roms, do NOT attempt this. If you need your tablet for work and something important, do NOT flash this rom. This rom could result in a bricked device ,boot loop, complete loss of data or non booting device or you not being able to revert back to your old rom.

Known issues/What doesn't work/what's not tested
NOTE: If any following features are important to you, don't use this rom as I will not be fixing them because I
i. don't use/need that feature
ii. already tried fixing it and couldn't succeed and won't spend anymore time on it.
1. Stock camera doesn't work at all (reason i and ii). Starting with LineageOS 19.1 and higher, camera API functionality (pictures and videos) isn't even recognized by the OS.
2. fingerprint (reason i). I never use it and I see it doesn't even load correctly in the logs.
3. ARM64 gapps (reason i). Some of you require gapps for whatever reason. I use Aurora Store for my purposes and thus have NO KNOWLEDGE of the current state of ARM64 gapps.
There are various gapps projects (at least 5 in 2023). Each has pros and cons. It's your job to do the research and find a suitable gapps project. I suggest you allocate at least a couple of hours/days doing your own research. My rom works by itself fine without gapps. DO NOT talk about gapps in this thread.
4. full disk encryption has been deprecated in Android 13 (LineageOS 20).
5. If you restart the device with the purpose to reboot it and the usb cable is plugged in, the device will not reboot and stay in charging mode. Simply unplug the usb cable, wait 15 seconds and restart the device.

Frequently Asked Questions. You MUST READ this before posting any questions. If you think this is unreasonable, then find another rom. Thank you.
Q1. Where are the source and kernel source files?
A1. The kernel source files are at
https://github.com/syphyr/android_kernel_samsung_msm8976/tree/lineage-16.0
The device tree files are at
https://github.com/retiredtab/msm8976-common/tree/lineage-20
https://github.com/retiredtab/gts210vewifi/tree/lineage-20
The vendor tree files are at
https://github.com/retiredtab/proprietary_vendor_samsung_msm8976
The manifest.xml (or roomservice.xml) and build instructions for LineageOS 20 are at
https://github.com/retiredtab/LineageOS-build-manifests/tree/main/20/msm8976
Q2. Is this ALPHA rom suitable as a daily driver?
A2. It can be depending on your requirements. I can't test every app so you try it yourself to see if it's suitable. I've been using this rom myself since Jan 2023 with no major issues. I suggest you do a clean install, see FAQ 11, and flash this ROM BY ITSELF (no gapps, magisk, etc) and see if you like it.
Q3. What if my app, xyz, doesn't work?
A3. If your app doesn't work, then go back to your old rom.
Q4. Your rom is laggy and buggy.
A4. If you find the above, then go back to your old rom. Your tablet will also run slower when you use gapps. You can run a lot of software without using gapps. Research fdroid, newpipe, Aurora store etc.
Q5. What TWRP should I use?
A5. You MUST use TWRP 3.6.2_9-0. Do not use any other version including the "latest".
https://dl.twrp.me/gts210vewifi/
I will not answer questions if you don't use this exact TWRP version.
Q6. Why should I use this rom?
A6. If you don't like this rom, then don't use it.
Q7. Will you offer monthly updates with security patches?
A7. I will try to offer monthly security patches, but that all depends on if I continue to have high speed Internet in the future.
Q8. Can you help me? I'm a newbie. Can you provide step by step instructions?
A8. I don't have the time to help newbies, so please do your own research. There are lots of tutorials, videos, etc on how to flash roms. Newbie questions must be posted in the Questions and Answers forum, not here. In addition, I don't run Windows OS at all.
Q9. Can I report a bug with respect to the rom?
A9. Yes, but you need to supply the following information. If you don't, I won't look at it.
You must provide an adb logcat of the problem and tell me how to reproduce it. Note I will not be downloading any apps that require money or an userid/password. For example, if you have problems with Netflix, I cannot help you since I don't have a paid subscription. If you use some app that requires an userid/password, I cannot help you as I'm not willing to create another userid/password even if it's free.
To get a logcat, open up a terminal window.
Code:
# clear the logcat first
adb logcat -c
# start logcat trace
adb logcat > problem.txt
# reproduce problem
# wait until problem has occured, then stop trace by hitting ctrl-c
# attach the problem.txt ZIPPED as text files don't seem to get attached properly
Q10. Will you build Android 14 and higher for this device?
A10. Any questions on higher Android versions will be completely ignored. I do this in my free/spare time and will not be subject to any ETAs or demands. If you want a higher version, the source code is freely available as per FAQ #1 and you can build it yourself.
Q11. Do I need to erase everything and format my data?
A11. Yes, you MUST erase all the partitions (system, data, dalvik/art cache, cache) using TWRP and MUST format your data before installing 20 when you are coming from stock or an earlier version of LineageOS or from another custom rom. If you get stuck at the boot animation for more than 5 minutes, it's likely because you didn't follow the instructions I just wrote. Dirty flashes from stock, other custom roms or older LineageOS versions are not supported and not likely to work.
You MUST FORMAT DATA in TWRP so backup your files first to some external storage (external microsd or PC).
NOTE: After you do the above, first boot (without gapps, magisk, etc) will take about 90 seconds. It may pop with a message saying "System UI isn't responding". Hit close app and then reboot the tablet again.
Q12. What gapps should I use?
A12. I don't use gapps anymore. I use Aurora Store. As of Nov 6, 2021, I no longer make recommendations on which gapps to use as your mileage may vary.
Let me by crystal clear. YOU NEED TO DO YOUR OWN HOMEWORK selecting between the various ARM64 gapps offered. There are 5: opengapps, nikgapps, mindthegapps, flamegapps and bitgapps. Each one will have it's own installation instructions. The only recommendation I will offer to use the SMALLEST version of gapps.
Don't be surprised that whatever gapps you use might have problems like "Just a sec", voice not working, updating google play store please wait, etc. These are NOT problems of the OS as the OS will run fine without gapps. These are gapps problems and you must ask in the gapps forum why it doesn't work.
In addition, some of the gapps may not install properly when using TWRP and say "cannot /mnt/system".
Q13. I'm having problems with gapps, can you answer why it's not working?
A13. I WILL NOT answer any questions regarding gapps. This thread is about the rom, not gapps. Android does not depend on gapps in order to work.
Q14. Why isn't my post answered or ignored?
A14. Questions already answered in the FAQ will be completely ignored. Again, I do not use Windows OS or gapps.
Q15. What speed up/optimization tips do you suggest?
A15.
1. Turn off animations. Go into developer settings, scroll down to the drawing section, and set window, transition and animator scale all to "off".
2. If you don't have a google account, don't install gapps. Use Aurora Store to get your apps as you can get all the same apps from the play store using an anonymous login.
3. Use a web browser like Brave that has built in adblock and privacy features.
4. Use newpipe to watch your streaming content. It has built in adblock so you don't have to watch forced ads.
5. Look for apps that are open source, ad free and lightweight.
Q16. Does this rom support Magisk for root?
A16. I don't use Magisk. Magisk is always being updated to fool Google's certification process which may or may not work.
Q17. Will this rom ever become official?
A17. With 19.1 and up, legacy devices like ours will NEVER be official due to lack of ebpf support. See https://lineageos.org/Changelog-26/
Q18. What is the difference between this rom and others?
A18. This rom tries to be pure LineageOS with little to no modifications.
Q19. Will there be any major 20 code modifications in the future?
A19. I don't anticipate any major modifications. There may be some small bug fixes and minor code cleanup, but all the hard work in getting the rom up and running and fixing all the major bugs have been completed. This doesn't mean the code is perfect or well organized, but I won't be doing any major changes now that 20 is working.
Q20. Can you build a variant of this device? For example, a LTE or S-pen version.
A20. If I don't physically have the device, I cannot and will not build it unless I can boot and test it myself. Even then, there's no guarantee that I can get those variant features working. To be clear, I will NOT build T713, T719 and T819.
Q21. Can I load this rom on a variant devivce like LTE or S-pen version?
A21. The rom is built for the device explicitly listed. If you are an advanced user and understand TWRP, adb, odin, heimdall, you can try loading it on a LTE or S-pen variant by modifying the updater-script, but it may cause a bricked device, bootloops or non functionality of LTE/S-pen. You have been informed and warned!
Q22. Does this rom support OTA updates?
A22. No and I have no plans to add that functionality.
Q23. Why is there no LineageOS 19.1 build?
A23. I actually had a private 19.1 build back in Dec 2022, but stock camera didn't work at all so I decided to try build 20 to see if stock camera works in 20 (it does not either). Since I'm the sole builder for 18.1 and 20, I don't want to build, maintain and test 3 roms each month. Since 19.1 and 20 are very similar, I decided to just do 20 and drop 19.1 altogether. For those that need stock camera to work, use 18.1 (with caveats) or another rom where it works properly.
Q24. Okay, I understand the consequences and that this is ALPHA rom and willing to take the risks outlined, now where can I find the rom?
A24. You can download it from
https://sourceforge.net/projects/retiredtab/files/SM-T813/20/
Release notes
NOTE: All builds that I upload have been personally tested on my device to boot and function as described in post #1. Having said that, there's still a chance it won't work on your device due to human error, your configuration, your apps, etc. If it won't boot, always start with a complete wipe of everything and format your data in TWRP. This is known has a clean install. Backup your data before a clean install.
June 23, 2023
1. Initial 20 ALPHA public release.
2. Incorporates June 5th security patches as per https://review.lineageos.org/q/topic:"T_asb_2023-06"
3. If you are coming from stock rom or an older LineageOS version (example, 18.1), you MUST format your data in TWRP. Remember to backup your data and verify that restore data works before upgrading to 20.
