information please - Samsung Galaxy Note 9 Questions & Answers

This is not so much a note 9 question but i am in the note 9 port of the forum and it deals with the android system.
I am trying to learn a few things about android OS. I would like to make a rom and know there are some good tuts on xda.
I happen to be a hands on learner. By that i mean i like to learn by doing so tuts are good but dont pinpoint my want.
I have a android streaming box. It is from what i have read a china clone with a rockchip 3328 chipset and a 8723 wifi chip. It seems the company i bought it from put out their firmware but its very buggy and there is no twrp for it but it dose have root. But not supersu. If i install supersu the binaries are out dated and if you update them it will bot boot.
Ok anyways my question is can i open the system img and change the launcher because no launcher seems to work just by downloading from the store. and edit the systemui and framework-res because it seems somewhere the notification bar and the nav bar are gone on the ui. I then would pack it up again and install like normal firmware.
What pratfalls will i encounter and if there is any write ups on something like this please let me know.
Lastly and it may be way beyond the scope of this post. What is the process of mak8ng or rebuilding twrp to work with my device i would really like to give that a go too.
Thanks for any input.

Debian on CyanogenMod?

Hello everyone,
I was wondering if I can run Debian on my CM. There ist this guide on this BBS, that explains how to run it on JF Mod. So will it only run on JF?
May the force be with you.
I was wondering the same thing. A buddy of mine is going to give me his G1 to play around with since he's gotten a new phone. Id love to run Deb on it, but am unsure. Im not sure exactly what firmware customization JF has done on his. If we could find that out, we may be able to figure out if it'll work for us by comparing it with what has been done with the CM firmware. (His site isnt all that specific as to the details and is obviously not as current as the CM development. JF writeup
Another question would be if we could just add it during the install. Just as how with CM you have to install the android parts that CM cant release... maybe we could add in the JF Rom before CM (but after the android rom) and hope that the parts it needs gets installed but doesn't break CM.
Ive never messed with an Android before, so I'm just guessing here.
EDIT:
After searching... I did find this post. (read the post and the reply)
So maybe its worth the shot to just try it and see what happens (I wont get my G1 till next week, so I cant give you any feedback before that)
Yes, you can get Debian installed on G1.. I have tutorials up on how to install, resize the image and then install a GUI for it... check it out: http://www.myhangoutonline.com/tutorials/g1/install-linux-on-your-g1
It would be absolutely awesome if that would work! I am giving it a try in a few days. Has anyone experience points with the linked method? Not that you are going to brick your beloved G1.
I also found those links on this BBS. I just thought it would be wise to post them here for you.

However almost all links seem to be outdated. They are a few month old what I think is suspicious since debian should attract much more attention. Any theories why there are only a few that are interested?
I just can recommend deb. Its a whole world of software. Probably the best on earth.
yes... the method i have in my tutorial works... I've used debian before on my G1... it will not brick it... it all pretty much runs from your SDCard. If you don't like it, just delete the folder and bam, it's gone...
Follow the tutorial... there are 3... 1 to install linux: http://www.myhangoutonline.com/tutorials/g1/install-linux-on-your-g1
then 2 more... after that one, you'll need to resize your debian image, then you'll need to follow the 3rd tutorial to install a GUI. all 3 are at the site... enjoy it! it's a lil slow, but it works. i would recommend it without the GUI, but you can try both and see which you like better.

[DEV]Chroot-Linux on Xperia Devices Locked/Unlocked Bootloaders(Debian,Ubuntu,BT5up)

Hi,
I have just bought a new Xperia Pro and Here is My first Contribution.Hope you guys like it.
I have tested it personally on the Unoffical MIUI port for PRO.But it should work on other Kernels and Xperia Devices as well.
I am posting a few Screens for you guys and as you can see lxde is already pre-installed for you guys.
Feel Free to comment

What is chroot?
A chroot image is like a Virtual Machine where you are running an O.S within an O.S.The point of this is that you have a whole Linux System running on a phone where you can ofcourse access all the utilities available in Linux.and as it runs inside of android you dont need to flash anything and can use both the chrooted O.S and Android together.
Things required:-
1)Terminal
2)Root
3)Sdcard with atleast 2GB of free space
4)A Brain

Hi! Have you tried this on stock kernel? I believe stock kernel doesn't have loop devices enabled and MIUI is a rebase of CM? Not sure though that's why I'm asking.

The Miui i used was on Stock Kernel.The Kernel Does Support Loop devices.Miui is a Rebase of CM but the loop functionality is related to Kernel.So,Yes it Works on Stock Kernel on Locked/Unlocked Bootloaders Both as we are not flashing anything.
Anyway Give Ubuntu a go.

Thanks! Just clarifying things out I haven't meddled with stock kernel that much that's why I am asking. Well the kernel sources sony provided has loop devices disabled by default glad that it's enabled on the official precompiled one.
Anyways! Try packing backtrack that should be alot useful than debian w/ lxde or a classic ubuntu image.
I got backtrack to run on Pro sometime ago when I was still using gingerbread.

Hi! seeing that you're a fanatic of these perhaps it would be useful if I give you these.
http://50.56.186.177/filez/
Those are packed and reduced sizes of debian & fedora arm images made to fit for chrooting on mobile devices. I made those for my previous device and is very stable already with 256mb RAM
the debian image is a squeeze version. Plus included is the fix for pulse audio. I'm not sure if it would work out of the box for android but with just a little bit knowledge with basic linux stuffs you could get it running perfectly

THANKS for the link...Meego wont chroot..tried it on the optimus a few months ago and failed..problem with zephyr..will give it a go later.fedora I had as well..but the thing is ...Does anyone except me even use these here????
I do but not that much. Like I said I just only tried backtrack and obviously I use it only when needed
Say do you think it would be possible to include a custom kernel on a chrooted image? It would be cool if we have backtrack here with monitor mode enabled. I think the wlan drivers/hardware of Xperia devices have the capability.
Or also try posting this thread to some other Xperia Sub forums. Arc/Pro users seem to be not very open to these kind of works. They just care on custom ROMs
In short they aren't geeky enough They aren't even that interested in dual booting.

In theory yes its possible.but changes will have to be made to the arm kernel to chroot.when u type uname in terminal the output inside the chroot is different than the android kernel.but I think native booting will be better than chrooting..not being interested is just odd....its so much fun having linux on the go

Actually I know I am going to say something Off-Topic
1) People on XDA are now the people who have got a smartphone just because they can afford one and wanna make their phone look "kewl" than the others with the same device
2) People do dumb things like cross flashing kernels.. They dont even read carefully what the OP says..
3) Running linux on a phone would be the best thing.. specially on an xperia pro where you get a harware keyboard..

Really ???? Why ?? Huawei is too slow in making the Updates , all now is Andoird 5 and P7 is stuck in 4.4.2
It's proberly better staying on 4.4.2 than on lolipop. Many bugs on lolipop.

Wow do you realize android 5 has been out officially for a week or two and pretty much every phone apart from nexus which uses the software directly from Google themselves who make android, still don't run it yet and expect to be running it in 2015.
Not even big teams that use the aosp code directly such as cyanogen or paranoid have got a stable fully functional rom out yet.
It takes time for the 3rd party developers to customize and test android for there devices once the official version gets released as they all use the final source code which only has been out 3-4 weeks.
Also no company apart from Google is much better, Samsung are still rolling out 4.4 to some of there devices with some like the s2 still on 4.2 and end of life presumably others will jump straight to lollipop from 4.3 etc.
Also on rooting what do you wish to achieve by doing so?
Rooting can be very dangerous if you don't know what your doing with devices like ours.
Take a look for example at all the posts in this forum asking to downgrade their l10's from emui 3 to 2 which they upgraded to custom versions etc without thinking and the issues they now have with boot loops and stuff.
If you want to run xposed you can find many people with similar things recently in this forum that can't get it to work.
Also rooting etc you lose the ability for any future updates via OTA and recovery and would need to manually update your device potentially bricking it every single time which bricking means you can no longer use your device and have to buy a new one.
Also are you capible on the PC with using it, command prompt Linux shell etc and doing things like installing Windows and other things.
If not then rooting is not for you.
Also do you know how to code in Linux C etc and know the workings of the Linux os, if not then there is no way you are going to make a custom rom. All you might be able to achieve is just repackaging someone else's ROM with minor edits and even then the tools to do that mainly use Linux to run as it's native windows doesn't have all the stuff Linux has natively in this regard.

Thanks For your Valuable words,
I really enjoyed them and get my mind open
well I do have Good Experience in linux and Command line , C Programming actually didnt go deep with it really ,
But i think I will stick to your opinion and wait ,and while I do so I will learn more about the whole subject ,and maybe increase my knowledge in this Field . (Android Programming - the C Programming - how things work in Android , ROMS , ETC)
but would you mind telling me from where to start ???

Apologies if I came across about abit hard this forum has had allot of impatient people jumping in recently trying to run Emui 3 on l10's then asking to downgrade as you may have noticed the other teams like paranoid are already dealing with lots of people saying there to slow for not having lollipop out within a hour of aosp.
I had the same issue running a custom Minecraft server that people got really angry then refused to play and bad mouth the server if we didn't update that day when update time for us was about a week given the number of customizations we had 41 plugin's in the end, sometimes longer if there were more changes the mod and custom server devs had to deal with.
Emui 3 and lollipop has more bugs more as it's new from what I found I may start a proper consolidated emui talk thread later for those running it opposed to all the l10 when are we getting it out help me downgrade threads.
The place I think you should start is to download the source code for your version from the emui webpage and start analyzing it out of interest.
There's another Dev on here doing the same thing so you might want to contact him for info.
Also there are tools on Linux that easily let you unpack stock image files and the ext container and repack them.
That way you can see the full file structure and how a rom is packaged.
It's good just to see what's inside roms and how the first roms are usually made by a repackage before source.
I will stress the same as above that while these are starting points you would need to know what you are doing and something more hackable like a cheap nexus or or Chinese tab (about $50 USD) with easy upgradable firmware something would be better to start on.
Also grab down the android tools with eclypse for Linux, the sdk virtual device and have a play around making a app and stuff also you can edit the virtual rom safely etc.
The Linux version of the tools is far superior as you can natively mount the virtual ext cards for host file transfer and do other things which you can't under windows.
By ext above I mean the virtual partition files which are either ext 3 or 4 last time I looked.
I'm not a coder myself and I only did basic stuff in the past as I had a Chinese android 2.2 tablet the MID ones as my first device, I used a custom rom on which was just a repack with file system changes with bloat removed etc.
I looked into this out of interest and curiosity, each rom update I repacked it with the apps I used so I didn't need to reinstall them, there was probably a better (proper) way than just unpacking the ext file system from the img adding my apps in to the deploy folder and repacking.
Also I unpacked a APK weather app etc to make changes and use a custom background and others like themes to grab icons and assets this is a good start with looking at app packages and how that all works as well as making your own app in various tools eclipse for one which is the official tool but there's hundreds of android programming softwares online even to do simple stuff as make a stand alone html5 app from a webpage.
The tools on Windows I found were lacking and harder to find for the rom stuff, with Linux it was built into the system a lot of things.
What Linux is the best for doing Android stuff I don't know so that will need to be researched.
As mentioned devices can be dangerous for custom stuff especially newer ones with bootloader security, the older Chinese style ones and some others you could reflash easily from sdcard with a update.img file as they didn't contain that lock out security on boot and debugging.
I nearly bricked a few devices in the past, once having to rely on the bootloader and Android Commander a powerful tool and device terminal to mount the partition rw while in the bootloader to rename a file backI renamed as a test that caused the system to stop booting.
You can still get some tabs that do that about 50 USD on eBay etc I think.

I'd strongly advise that you wait. My experience. You can root v4.4.2 VERY easily using vroot. Wait for lollipop, honestly. Is a nightmare recovering your position if you try to move now.

Root? Yes or No? Why?

Hello everyone. Those days I feel some to root my phone (ALE-L21 6.0 Dual SIM) to install custom ROMs like LineageOS with Android Nougat and use apps like WPS WPA Tester but other some I feel not because I'm still in warranty time (it ends after 1 year + the warranty isn't in my country) and I never rooted any device or even used Android (my lase phone was Nokia 110) so today I wanna to know why root is useful and why not and what can I use it for and what's the root dangerous? I need all informations about root. :laugh:
Edit: Is all custom ROMs has bugs? Like Radio FM doesn't work, screen recorder doesn't work or even has a bug?

Root was a good thing on earlier versions of Android. Now I don't think it's a necessity.
Custom ROM's seems a good idea, but if you don't have official version from the developers I myself don't recommend it.
You can try deoxed, modified or trimmed versions of stock ROM, to get more features.
If you have a branded phone I recommend to unbrand it to obtain ROM updates easily.
I recommend to keep stock for now because we get security patches from time to time.
I think main reasons for rooting and unlocking bootloader.
1. Devices with small memory you can install apps in to SD-card.
2. If you realy hate ads you can use Adblocking.
3. Install custom ROM or kernel to get better battery life/performance (with some devices these are only stuff that isn't perfectly stable but sill stable enoughfor daily use).
4. Uninstall unessesary system apps.
5. More customizing possibilities like change screen dpi(dots per inch --> smaller value gives smaller icons and text so you can fit more stuff in screen at the same time).
6. There is more things to do but this was of the top of my head.
IMO root yes, of course, many reasons pick the ones you like most: uninstall bloatware, tweak kernel parameters, activate hidden options, xposed, greenify...

1. I use my device currently and needn't more space.
2. I already have Adguard, it's enough for me.
3. Yes, I've bored from the stock Android theme and want to change it.
4. I needn't to remove system apps because I don't even use them.

Well I forgot to tell most important reason, because you can : D
Nowdays that's prety much all the stuf that matters for regular user.
Maybe bagroundplayback for youtube if it isn't already possible with regular app.
And it's kind of a plus that you can back backup your full system in TWRP, thought main reson for backups is that you are testing something unstable or new stuff which you can only do with unlocked bootloader.
PS. Your logic in 4 is kind of weird XDD
And dpi is kind of like resolution of screen but still very different but you can think of it as a weird resolution setting

I recommend to keep stock for now because we get security patches from time to time.

IMO = In My Opinion
bloatware = preinstalled apps you don't want but can't remove
tweak kernel = change kernel parameters such as min/max speed, governor, i/o scheduler, gpu speed and so

I'll try to be brief.
First I rooted my Samsung Galaxy S plus, android version was 2.3.6. Was a good thing? Yes, I had good devs who not only made Rom's up to Lollipop (I use now KitKat on it) but also repartitioned the space available through Twrp giving me more space for apps.
My next one was Galaxy S3 mini, android version was 4.1. I rooted it. Was a good thing? Yes and No.
Yes was good because I could use apps for backup, to remove bloatware, and posible to try custom ROMs.
No... Because I didn't had good developers, every custom ROMs had issues. That made me feel cautious and only installed stock ROM's that gave me more personalization and stable use of the phone (that doesn't mean I don't have problems with it, but it's mostly caused by apps who are not 100% compatible with KK ROM's).
Now let's talk about P8 Lite.
1. Can I squeeze more time of use from battery? Yes, we got the option <Ultra battery>.
2. Can I disable bloatware? I can't remove apps but I can disable them (MM has an option for it).
3. Can I backup apps and data? Yes. We got an option for it.
4. Can I get security updates for my ROM? Yes, for now we get security updates from Huawei.
5. Can I customize my ROM? To a point... Yes, you can customize the interface through themes, and the theme itself using other apps.
6. Can I get Nougat (version 7 of Android).
No, and you can start blaming Google for the requirements asked for it.
Yes, if you buy the 2017 version of the phone.
Sorry I was not brief. :good:

Awesome, that's why I want to root it but I'm still waiting until LineageOS be available and stable without bugs for me. I bought my phone last year and updated it to MM 6.0 at 7 month of last year, now I have UPDATE.APP (got it from here) it has no bugs and too stable for me. So I saw tutorials here for rooting my device but it were too much big and I need to use my computer. NP if I used my computer but can't I root it using apps suck as KingRoot and then install the ROM? Also I want to know all thing about bootloader and unlocking it and all thing in this operation. I want to know to be deep for such as problems. Thanks for info

Few years ago, when we could not imagine that phones can get ROM updates, no one bothered about bootloaders. But after few years they were shocked to see old clients use same depleted phones with new ROM's.
If you look back, when Google started to release Android 3 and up, we can see that the manufactures didn't try to much to improve "the smartphones", the selling ideology was the same as before, manufactures imagined just few improvements for the new models.
But then iPhone appeared, Samsung Galaxy smartphone line appeared and rules changed. Everyone tried to sell smarter phones on the market, Apple had a closed system so everyone looked at Google and android delivered.
So after the "Wild West" period, manufactures wanted more control over their devices, don't forget that devices had hardware in many configurations, so to prevent bricked phones, to try to stop clients from destroying their devices and after ask for guaranty, bootloaders were invented. It's a compromising way for users to obtain root access and avoid warranty claims.
Now, we see that Google stepped a bit, with Android 7, by limiting the compatibility asking for minimum hardware from manufactures. It's a way to make clients buy new devices. Same thing we saw at Microsoft when it released Vista and up. It's a good way for manufactures to stop companies like CM to make unwanted ROM's updates. At the beggining CM ROM's where 100% bug free, but now we can't say the same. Manufactures don't release drivers for hardware so developers to implement new versions of Android on old devices.
For me the only viable option for ROM updates is stock modifications that try to remove restrictions in the software available thru all the world.
But why is Huawei giving a legal way to unlock the bootloader? It's a very easy way to see who still got guaranty and who is out of guaranty. And also it's a way to keep clients close by getting ROM updates faster, it's basically a removal of the middle man (manufactures can't live without firms that do installment sales) a way to increase the overall sales.
Imagine a person who needs a smartphone but can't afford it. Carriers can give devices for less, manufactures get the full price, and carriers get the whole price with interest over a limited period. And now manufactures have a problem, they need to keep clients of carriers happy, and need to push updates on the devices. Carriers see this as a loss of control, but can't make the manufacturer to keep the system closed. So for legal requirements bootloaders were invented.
You can ask for root, but manufactures and Google is giving secure control over the devices, that basically do same thing as apps that required root.
My final advice: if you don't plan to learn about android ROM development, if you don't plan to be a developer, then don't root. Wait until you get a new device, maybe with the new iteration of ROM. If you see something you like, then you can start learning and start developing.
:silly: can't believe i wrote so much. Happy reading and good luck.

Extremely awesome and thanks a lot. I want to start to learn about root but IDK from where can I start! There are no way to root any Android emulator and learn from it or executing on main device would be more stable?
IMO, root device it's a personal choice, the important question is:
There's something that you want to do and you can't because you need root?
To install custom rom you don't need root, you have to unlock bootloader, install a custom recovery (TWRP) and finally you can flash you custom rom (generally already rooted!)

Ciao amico mio ? (some Italian from school ?) can you give me a tutorial for this? I need to try. Also why there are a lot of stuffs to root ALE-L21? What if I used apps such as KingRoot?
Ciao!
Kingroot, if it's working again, isn't a good root solution; i've tried (we were with lollipop) but messed up a lot of things so i had to re-flash stock firmware.

Yes for :
Tweak kernel, install AdAway and remove preinstalled apps.
personally for me is a must, i just do much things with root, anyways you could say i'm an advanced user of android so i need root, if you are good with your phone as it is, or a newer user of android, you don't need to root

I don't like normal things, I need to be special that's why I think to root my device. I'm neither pro nor newer. So I need to know if I rooted my device what will I do else custom ROMs and block ads and remove system apps?

[SOLVED] Battery drain on custom ROMs running on SO-02K(Japanese docomo model)

I'm using Xperia XZ1 Compact SO-02K (Japanese docomo model) unlocked bootloader via qUnlockTool.
I installed some custom ROMs like LineageOS 18.1, Havoc OS 4.8, 3.11.
Any ROMs doesn't go to deep sleep so the battery drain is so bad. I installed Android 11 ROMs and 10 ROMs, but both not working deep sleep.
Anyone know good solutions?
Hi,
great to see some other user from Japan with the SO-02K. I also recently installed a custom rom and had the same issues as you. The source is the NFC chip. Unfortunately the Japanese version have a different chip/driver because of the Felica services here (Felica was here in Japan well before Google was even thinking to integrate NFC in Android, so nobody to blame here, beside Google, not Sony.)
Anyway the fix is a bit ugly. However, there is help:
Download this image from here: https://forum.xda-developers.com/t/rom-lineageos-18-1-unofficial-2-0-update-2021-01-20.4047763/
Yes, this and only this. I know it has not been updated anymore, but the reason comes below.
Please check out this thread: https://forum.xda-developers.com/t/fixed-xz1-au-sov36-japan-deepsleep-on-g8341-custom-roms.4156209/
It is about the XZ1 AU version but it also applies to the compact. I summarize here to make the post complete:
Either you root the phone, which I did not do because I do not need root for anything and with root, some of my app do not work, like Spotify. So I recommend to do those steps in the TWRP. Simply mount all the partitions and go to the file manager under advanced options.
Go to folder: /vendor/lib/modules
and delete or rename file call pn553.ko
Restart your phone and it will go to deep sleep. Otsukaresama.
Now, why only this image. Because it uses the older NFC library. In all other images, this fix this not apply anymore, as the modules are not at that place. I really would appreciate if someone more experienced can point me to the nfc module drives in any newer LineageOS image.
PS: Of course NFC will never work with a custom rom (without trying yourself to find out how to make it work)
Best

Thanks for good solutions!
Actually, I couldn't find pn553.ko on the latest stock ROM(47.2.B.5.38), so I deleted all of NFC files in /Vendor (of cause I took /Vendor backup with TWRP.). The deepsleep little works (please check attached picture) but the battery drain is better than before.
Thanks anyway!
