[MOD] EXT4All Continued + Now with TWRP 2.3 Support

The purpose of this thread is to host a location and continue support for a really neat ext4 mod.
IMPORTANT: If you flash the no data limit mod you need to do it after every update or your data, which won't be lost will be hidden by the contents of the data data partition.
I'm going to keep this brief. The original thread was closed so I wanted to have a new location where everyone can find the files. But this is a new thread for Jermaine151's and my EXT4all mod.
Below is the original thread which already has a lot of useful information:
http://forum.xda-developers.com/showthread.php?t=1315372
Here is where you can find most of if not all the EXT4All files:

Sorry this thread isn't too organized but I threw one together so people could post on it with their comments.
This mod should work on all AOSP ROMs including ICS ROMs and MIUI. It's been confirmed on CM7 and MIUI but I've also tested on CM9. It should also work on all Sense ROMs and does work on every Sense ROM I've tested. Be sure to flash a newer version of the gingertiny kernel if you use a Sense ROM as the kernel version flashed to add ext4 compatibility is out of date.
V2 Mods with TWRP 2.3+ support and proper support for filesystem tweaks for ROMs that are already set to use ext4 found below:

FAQ
Q. How do I know if the ext4 mod(s) worked?
A. The best way is to do the following from terminal:
su
mount | grep /data
It should show a line with /data and ext4 and, if it has the no data limit, also a line with /data/data and ext4. If you're on an ICS/JB ROM it will show ext4 anyways. The best way to tell with the new version of the mod is to see if noauto_da_alloc shows in the results of the above commands.

Hey tiny, thanks for opening this btw. Wasn't sure if I should post here or on ur kernal thread but my girls dinc was having the data limit problem so I wiped cache and dalvic, flashed ext4 no data limit normal dalvic then flashed ur newest kernal (3/11 date). And I have been having the hardest time keeping her phone stable. I've tried every governor sav2, interactivex, ondemand, even sa, tried deadline, sio schedulers, even tried raising the voltages to a post u had on ur kernal thread, page 85 or something (wasn't sure if I should set the min and max of the voltages for the same thing, but that's wat I did). But she still says its very unstable. She's running stock+ 3.01 and she DOES have a cheap ebay battery in her phone, not quite sure how much that plays a role in the problem. She's at work right now so I can't pull any logs, but I know ull probably need a logcat? Or I dunno. If u could gimme directions on anything I should post to assist u. And I'm not overclocking at all for the record. On stock kernal she never had any stability issues, uptime of 200 hours+. But urs is definitely snappier and that damned data limit is the main reason y I even switched her over to begin with. Thanks tiny in advanced for everything u do!!!

I'd prefer the kernel thread.
And I'll need a last_kmsg. Just copy /proc/last_kmsg with root explorer or another file explorer and attach it to a post on the kernel thread. Since you most likely eliminated undervolting by using the voltages on page 85 of the kernel thread, then it's possible the battery has an effect. I've heard that poorly made batteries can cause issues that stock batteries don't have so further deviation from stock may have an influence. Either way, I'll look at that log once you get it. Make sure not to battery pull until you can copy that log and try to do it within 24 hours of the last reboot to be safe.

the following thread contains very simple and plain english directions for using this MOD. it helped me, and it was my first time rooting. Thanks also to tiny4579 for posting this new thread.

Question about this mod, I am running CM7.2, RC2, and onto rc3 soon.
I am having random resets, problems w/ my phone freezing, a mysterious message "sorry, process system is not responding", and other various issues. Could it be that the mod is causing some problems for my phone, or more about something that wasn't cleaned out when i flashed over a nightly?

Try a logcat before wiping which i would suggest in the end or else we won't know. I don't think the mod would cause that though.
Also pull /proc/last_kmsg.

I've been running various ICS roms and switched back to Warm rev 58. Upon installing the latest kernel and the Ext4 mod. I am unable to install apps. Any idea what may be causing this. I wasn't sure if it was the rom or not do I did an update with SVN and installed that with the same results. I have a nandroid with just the rom and all the apps I want, but would like to overclock and the stock kernel won't allow. And would also like to be able to install a new app should one arise.

Aw yeah.

Ok. It's not the kernel. Installed the most recent and everything is fine. Installed the ext4 with dalvik moved before that and rebooted and apps were missing and it wouldn't let me install new apps and some of my previously installed apps were missing. When I tried to install them it said it was going to replace an existing app and then said app not installed.
Any ideas???

hELLO!
I HAVE A LOGCAT!
and it captures 2 errors.
First, it captures the "sorry, system process not responding" error, and then it captures this weird thing where it restarts. it doesn't go all the way back to the "htc incredible" screen, however, it goes to the cyanogenmod animation, starts up, and THEN goes right back to the cyanogenmod animation, again!
finally, i shut it off, cuz i didn't know how to get the logcat to stop in ddms.
and i have the /proc/last_kmsg... how do i get it to you?
i added a .txt to the end of it so i could upload it, hope that works. is that what you need?

Try fix uids in amon ra recovery. Amon ra should be listed in from manager. I don't think it's the same as fix permissions in cwm which I believe there is file system based. From looking at your logcat there are a lot of unknown permission errors. Let me know. I'm at work so didn't have a lot of time to respond but wanted to check briefly.

hey, thanks for looking at it. what do you do for work, that you are working during a holiday?
so, you think i should try fixing user id's in amon ra recovery.
and it should be listed in ROM manager, right?
Now, here's the question, if i'm going to be trying the new RC3 in CM7, and this time i am going to do a clean install, erasing everything. would i still need to fix permissions?
or maybe i should try flashing over RC2 and then fixing permissions?

Always worth a shot.. If you have the spare time try to flash over and fix permissions as 2nd~to-last thing you do before rebooting, ext mod should be last. Same with if you do a clean wipe to flash RC3 if flash over does not help.
I've personally never had an issue after a clean wipe with permissions, but it would not hurt if you did it anyway. It has been recommended when flash over though as a standard procedure. But only recommended

okay, so when flashing rc3, make sure i fix permissions right before the last step, and then flash ext4all mod LAST on the list?

If you're wiping I don't see the point of fix permissions as it will fix it back to what it already probably is. I haven't fixed permissions in a while flashing ROMs and I've been ok. Force closes that I got that made me try fix permissions then weren't fixable with fix permissions anyway.
I would wipe, flash ROM, flash kernel if desired, then mod. Though if it's a sense ROM I would switch the order of kernel and mod flashing. So really you can do: ROM, ext4all mod, kernel after a wipe if you choose to wipe to fix your issue.

hey, flashed over to RC3! so far so good, slowly adding things back! will let everyone know how it goes!

Is there a possibility that all or part of this mod could be persistent over multiple wipings?
My reasoning for this question: I originally flashed the 1.0 normal mod on Nils' BGS. In the OP it says it converts the filesystem to ext4. Many moons later, and now on drk's CM9, terminal still lists cache and data as ext4. I did not, however, flash an ext4 mod on any versions of ICS. I know that when I do a factory reset, even though all is formatted, my sd-ext remains ext4, since I set it up that way for Link2sd. Is it possible that the data and cache blocks have also remained ext4 from the original use of this mod, despite wiping and formatting repeatedly?
...sorry...I was on the phone...

No, if you actually format the device like when the system runs the format command the filesystem will be ext4. However in your example of CM9 the ramdisk mounts data and cache as ext4. This will actually have a minor improvement over ext3. It'd still be an ext3 filesystem but loaded as ext4 so there's minimal performance gains.
In reality any time you flash a ROM or a boot.img type kernel (not any of mine) you will use the ramdisk of the ROM and reverse part of the effects. But since ROMs like CM9 and newer CM7 versions mount as ext4 you'll still see data and cache showing as ext4. Make sense? I never really did explain it properly before I think.

[THOR/RECOVERY LOCKED] Safestrap Recovery v3.72/v3.75 [B02 2014-07-03]

ATTENTION: I will be stopping official Safestrap support on 9/1/2014. For more information please see:
https://plus.google.com/111109372727398356624/posts/AtoJ3xLj35b
*** DISCLAIMER ***
I work on projects that may brick your device. Don't sue me, hate me or try and kill my dog if that happens. I will feel bad the community will feel bad and hopefully we'll find a way to get you going again. But, the very nature of my projects involves a certain amount of risk taken by YOU. And by using the projects that I work on, you've accepted that fact.
PLEASE PLEASE BE VERY CAREFUL WITH SAFESTRAP!!
MAKE A BACKUP OF STOCK RIGHT AFTER YOU GET SAFESTRAP INSTALLED SO THAT YOU HAVE SOME KIND OF DISASTER RECOVERY.
THEN YOU CAN RESTORE IT TO A ROM-SLOT (AFTER YOU MAKE ONE).
ONLY MODIFY ROM-SLOT FILES. LEAVE YOUR STOCK ROM ALONE!!
WARNING: THERE IS AN UNKNOWN ISSUE WHERE IF YOU HAVE ENCRYPTION ENABLED AND INSTALL SS IT BOOTLOOPS. IF YOU FIT THIS DESCRIPTION PLEASE STAY AWAY FROM SAFESTRAP FOR NOW.
UNKNOWN ISSUE: If you try and start Wifi and the device crashes/reboots, try turning on bluetooth prior to enabling wifi and see if that works.
CURRENT PROJECT STATUS:
BETA-STABLE
WHAT IS SAFESTRAP?
Safestrap is a Bootstrap / Recovery for locked bootloader phones. The goal is to avoid touching your primary system (I'll call this "stock" system) and only flash or make large changes to another place on your phone that Safestrap treats as a "2nd system" (in this case, it's a series of virtual ROM slots located on the internal emmc area: "/sdcard"). Once installed, you will see a "Splashscreen" giving you the option to hit "menu" to enter recovery. The recovery portion of Safestrap is now based on TWRP 2.7.x.x (a touch based recovery) and you can perform .zip installs, backups and restores here. The additional features I've added to TWRP are mostly located under the "Boot Options" menu:
Here you can create virtual ROM-slots for flashing ROMs. These ROM-slots allow for different sizes of /system, /data and /cache partitions. The defaults *SHOULD* be good enough for flashing the stock-based ROMs.
NOTE: The bigger you make these partition the less room you will have to make other ROM-slots.
You can activate a new ROM-slot by choosing the slot you wish to make active and then selecting the "Activate" button. Once active, you will see the "rom-slot#" up in the top of the screen shown in green. If you make the "stock" ROM active, then you can see it in the top shown in red.
Once a ROM-slot is active, all actions you would normally perform using TWRP are directed to that ROM-slot. For example, "Install" to flash a .zip, backup and restore.
For more information you can read up here:
http://blog.hash-of-codes.com/how-to-safestrap/
HOW DO I INSTALL SAFESTRAP?
Requirement: Rooted w/ SuperSU installed
Requirement: Allow APK install from Unknown Sources
Download the Safestrap APK
Find the APK using a Filemanager tool and open it on your device, then click "Install".
(If updating from an existing Safestrap you might be warned that this will over-write the existing installation. Click the "Yes" equivalent to this message.)
Once installed, open up the Safestrap application as you would any other app.
Agree to the disclaimer that you won't try to sue me and hunt me down with a rifle if you manage to break your phone..
Then use the "Install Recovery" button. You should see the current version down in the lower left corner of the window. And the "Status:" should say "Installed" when you're done.
From there you can reboot and you *should* see a new splash screen during the boot up. While this is showing you can enter Safestrap Recovery using the [ menu ] button.
That's it for the installation! Read below for a brief overview of Safestrap Recovery v3.x
HOW DO I ENTER RECOVERY?
During each reboot a splashscreen will be displayed showing whether the device is running a rom-slot or on the "Stock ROM".
Press the button shown on the screen to either enter "RECOVERY" or "CONTINUE" booting.
HOW DO I UPGRADE SAFESTRAP?
Push the APK up to your sdcard.
Boot back into the "stock" rom-slot.
Go into your old Safestrap app and use the "Uninstall Recovery" button
Open an "explorer" of some sort (ESFileExplorer, etc)
Browse to where you pushed the APK
Click on it and install like normal
Once installed, open the APK
Grant SU access
Use the "Install Recovery" button
All set, now you can reboot and re-activate whatever rom-slot you were using

As of version 3.x, Safestrap Recovery is now based on TWRP. For more on TWRP you can visit their website: http://www.teamw.in/
WARNING: Safestrap is heavily modified to be "Safe" for your device. Do not download TWRP from their website and expect it to work the same way. Also TWRP does not support Safestrap, tho some issues that may come up will be TWRP dependant, please try and contact myself or look on the forums for your device for answers before hunting down TWRP people. They won't be able to help w/ Safestrap specific questions.
For the purposes of direct user testing I've established a channel on freenode.net IRC: #safestrap
I'm in the channel mostly all the time, but may not be active for discussion.
Special Thanks To
DeesTroy & TeamWin for all their hard work making TWRP such a fantastic recovery

KNOWN ISSUES WHEN USING ROM-SLOTS (The ROMs are kept on loop device mounted partitions)
1. In theory you will lose an extra 3-4 percent battery compared to normal usage from 100% to 0% due to the extra read/write work involved when using ROM-slots.
2. The /data partition is kept separate from the "/sdcard" contents on SS ROMs. This causes the Storage settings to only show the size of the loopback data partition and then it shows "used" which includes the "sdcard" + /data so this can look odd at times (larger usage than partition size). It doesn't have any adverse affects that I know of.
3. No custom kernel flashing support at this time. Don't try it. It won't work. All kernels need to be signed by Amazon at the moment.
CHANGELOG:
[v3.75-B02]Bugfix rom-slot booting
[v3.75-B01]TWRP 2.7.1.0 update + display fix for 13.3.2.3.2/13.3.2.4
[v3.72]TWRP 2.7.0.0 update. *** This includes a bugfix for backup time showing correctly ***
[v3.72]Raised /data partition size to 16gb
[v3.72]Swapped "Reboot" -> "Download" mode to "Reboot" -> "Bootloader" (places you in fastboot mode)
[v3.70-B01]Seems like I have a solid fix for the "snow" effect when getting into Safestrap sometimes
[v3.70-B01]System partition now matches stock EXACTLY. You can't even change it in the settings due to the way I'm creating it during rom-slot creation. It's not a bug, that's on purpose. That being said, there should be plenty of room in that space to do what we want.
[v3.70-B01]Battery % now being displayed correctly in recovery
[v3.70-B01]Updated to latest Safestrap sources
[v3.65-B01]Initial release for Thor (Kindle HDX 7")

Thank you for the answer.
I'm not yet an owner of this tab. I'd really want to buy this beast (8.9), but the fireOS is stopping me. So I'm eagerly awaiting for a custom rom. Locked bootloader "turned me off"
So, 1) do you think safestrap can be a solution for a real daily driving custom rom (I guess CM)? Or just something to try/play with?
2) is there any chance/hope to unlock that armored bootloader?

Awesome work Hashcode. You've made two of my devices bearable to live with.

Sorry, but not yet. I talked to Hashcode and he was saying that since we can't use custom kernels yet, we can't use AOSP (Paranoid Android, Cyanogenmod, AOKP, CarbonROM, etc.) roms. It's okay, though. I plan on making a rom that will give you as close to CM experience as possible while still staying on an Amazon ROM.
As for the question regarding bootloader unlock, I'm not sure. I'm still in the process of experimenting with different things. I haven't had time recently though.

[HOWTO] Changing Filesystem to F2FS on the Sprint S4

This guide is for the Sprint Galaxy S4 only and as of now it is only compatible with two kernels: KToonsez S4 Kernel 4.4 AOSP (4/17 or later) and PoKernel 1.7 F2FS ONLY Build. This guide CANNOT be used on Touchwiz or Android 4.3 yet. I will update it when and if that becomes possible
*Disclaimer: You are doing this to your phone under your own consent. This is an experimental procedure and may not work on some hardware revisions or on devices where certain conditions are not met. You assume all the risk by flashing any of the software below or changing your filesystems. I am not responsible if your phone does not work based on the method I am describing below. Modify at your own risk.
This guide had to be updated in order to correct misinformation. The guide will follow KT's instructions explicitly until it gets to the formatting of the system partition
***If you want to format your /system partition to F2FS please read that section first as it requires steps to be taken from your currently working AOSP rom!***
First, go this link download the file:TWRP-KT.ALL-IN-1.zip
http://goo.gl/HLz4al
Formatting Data and Cache to F2FS
NOTE: Follow these steps EXACTLY, do NOT add or remove any steps, period!!!!
1. Backup everything from your internal SD to your PC or external SD, since the entire internal SD is going to get wiped out with format!!!!!!!!!!
2. Download the files from the folder that you got these instructions from (Ignore the OLD WAY folder) and SAVE TO THE EXTERNAL SD!!!
3. ONLY DO THIS STEP IF YOU ARE ON AN OLD VERSION OF MY TWRP. Flash TWRP-KT.ALL-IN-1.zip (this is what gives us the ability to format using F2FS)
4. Reboot recovery
5. Go to "Settings" and check the box to force F2FS for data and cache (you can also check the box to include /system partition if you want to convert your ROM's zip to use that too)
6. Go to "Wipe->Advanced" option and wipe the "Cache" partiton
7. Go to "Wipe->Format Data" option (THIS WIPES YOUR ENTIRE INTERNAL SD CARD, all files and folders, all gone so make a backup to your external SD or PC!!!!!!!!!!!!!)
8. This step you have 2 choices:
A. Flash your ROM/gapps to start completely fresh
B. Go to restore option and ONLY restore your "Data" (you can also restore /system if you are doing the f2fs conversion on /system partition too)
9. ONLY DO THIS STEP IF YOU INSTALLED A NEW ROM. Flash my newest kernel (needs to be a kernel dated 05.05.2014 or newer)
10. DONE!!!!!!!!!!!!!
11. KTweaker has a new option under "Tools" screen to "Get Partition info" to double check your work.
Formatting System Partition with F2FS (Required: KT SGS4 Kernel 4/28 or later!)
Steps:
1.) Before doing any F2FS conversion with the above instructions, use your currently working AOSP ROM to grab the AOSP 4.4 Kernel from HERE (4/28 or later only!) and save it to your external memory card
2.) Once it is saved reboot to recovery and install it (Flashing a kernel in TWRP is Install -> Folder where kernel is -> Click KT 4/28 kernel -> Swipe to install -> Clear cache/dalvik -> Main menu -> click advanced -> Fix Permissions -> Reboot to system)
3.) After you are back in your working AOSP ROM with KT 4/28 kernel installed, download the AOSP rom you want to use and save it to your external sd card (You can leave the filename as it is, the program will rename it for you)
4.) Open KTweaker and click "Tools" and at the very bottom choose "F2FS: Convert ROM ZIP"
5.) It will ask you to locate the file, ask if you're sure, and then it will do the conversion; upon completion the zip file that was created will have "-F2FS.zip" at the end of it
6.) Now you can follow the steps above, but when you get to step 9A you will use the "-F2FS.zip" file instead of the standard ROM file
This procedure is necessary because KTweaker changes your favorite ROM to pass the command mkfs.f2fs so that your system partition is formatted to F2FS before the files are installed. I did this myself to verify and it works a treat. One crucial step to remember though is that after you install your F2FS converted ROM you absolutely must install KT's kernel so your phone will boot.
Returning to EXT4
NOTE: Follow these steps EXACTLY, do NOT add or remove any steps, period!!!!
1. Backup everything from your internal SD to your PC or external SD, since the entire internal SD is going to get wiped out with format!!!!!!!!!!
2. Download the files from the folder that you got these instructions from (Ignore the OLD WAY folder) and SAVE TO THE EXTERNAL SD!!!
3. ONLY DO THIS STEP IF YOU ARE ON AN OLD VERSION OF MY TWRP. Flash TWRP-KT.ALL-IN-1.zip (this is what gives us the ability to format using F2FS)
4. Reboot recovery
5. Go to "Settings" and uncheck the box to force F2FS for data and cache (If you checked the box to include /system partition uncheck it first)
6. Go to "Wipe->Advanced" option and wipe the "Cache" partiton
7. Go to "Wipe->Format Data" option (THIS WIPES YOUR ENTIRE INTERNAL SD CARD, all files and folders, all gone so make a backup to your external SD or PC!!!!!!!!!!!!!)
8. This step you have 2 choices:
A. Flash your ROM/gapps to start completely fresh

FAQ
Q: Why can't I use this on Touchwiz?
A: It has been developed for the most recent Linux kernel 3.8 and has been implemented in kernels built for 4.4.x OSP builds. This isn't to say it cannot be used on Touchwiz, it is a filesystem and as long as there is a kernel that offers support for reading it installed on your device it should theoretically work on your hardware. However, this can be proven/disproven by the devs here and I will update this answer if it cannot be implemented in a backwards fashion.
Q: Are there advantages to using F2FS?
A: It is built and intended for use on flash filesystems which our devices run exclusively. So since it was developed for flash memory there will be a benefit to using it as it matures. However, this does not imply that benchmarks will increase or your whole phone will become more responsive, its intent is to have files be accessed and written more efficiently. It is supposedly also built for the long-term user who does not constantly reformat their devices because it is supposed to handle large amounts of old files and cleaning more effectively that EXT4. Source: https://www.kernel.org/doc/Documentation/filesystems/f2fs.txt
Q: Will this trip Knox?
A: No more than installing a custom recovery would. So if you already had a custom recovery (Read: TWRP, PhilZ, CWM) in place you are safe following this guide. For now of course; I do not know if there will be another iteration of Samsung software that locks down the device futher.
Q: Can I clear Cache and Dalvik to troubleshoot after changing my filesystem?
A: I tried this myself and the answer is yes. As long as you are using the F2FS custom recovery made by KToonsez you can wipe Cache and Dalvik from recovery and it will rebuild your system. Something I did notice is that first boot will stay on the splash screen longer with F2FS than with EXT4. I saw it hang on the splash screen of my Liquid rom for an extra minute before actually booting and showing cache rebuild. **Your Mileage May Vary**
Q: Why isn't the System Partition formatted into F2FS?
A: This can be done now with KTweaker. See section above.
Q: What ROMs can I use with this filesystem?
A: Any 4.4.x rom (most are 4.4.2 now) that is compatible with either KToonsez S4 AOSP kernel or Pokernel 1.7 F2FS Only.
Q: In Advanced Wipe, Preload has been added to the options of things to wipe. Should I?
A: Ktoonsez answer found HERE was that he has never wiped preload. So I suggest against it unless you know what you are doing.

Great guide OP! Always nice to have a thread to link to.
I'm sure it's been talked about but your posts doesn't mention the ramdisk files. They're listed but not talked about. Now I'm somewhat limited myself in understanding everything there is to know about these things but are those files to do with eventually formatting the system partition to f2fs?
May be worth putting a little note in there regarding those files... You know how some folks go flash crazy once in recovery lol

Hello again.. Lol
The ramdisk mod is now obsolete as it's already included in the kernel zip, which will automatically determine whether you're still on EXT4 or F2FS and make the required changes to the ramdisk accordingly. So no need to flash anything but the kernel as usual after following the steps.

OK yea I figured it was either to do with what I said or to do with the kernel obviously. Just figured I'd ask anyways
Sent from my SCH-I545 using Tapatalk

I'll be the first to admit that I wasn't entirely sure what the ramdisk files were for. I knew they might have been for advanced users considering they were offered, but not listed in the instructions. I didn't know for sure and I didn't want to use the word "obsolete" because, well, I was so wrong before
I am glad LuigiBull23 jumped in and answered that for us. I'll get it added into the the guide so future users know what they are or are not used for. Keep the questions coming, I love learning about this stuff!

I understand. A lot of people were and still are confused about these files..
In short, during the testing phases of F2FS, KT compiled a separate zip for changes to the ramdisk that in turn would reflect the EXT4/F2FS mount points as a means to avoid possible bootloops and such. It was indeed a success and as a result was included in his kernel.
Now, upon flashing the kernel it is able to determine which partitions are formatted as EXT4 or F2FS and mod the ramdisk accordingly. He only left the files on his server in case he ever needed them again. So they are most definitely OBSOLETE. You certainly wouldn't have gone wrong using the term in this case.

Updated the guide for KT's new all-in-one TWRP recovery that will allow you to switch back and forth between F2FS and EXT4. I used his exact instructions from his guide in all areas except for the system formatting section which I wrote. If you are using his custom TWRP recovery go ahead and grab the new one so you can use it in the future!

F2FS with CM11 Nightly
When I used KTweaker to convert my latest CM 11 nightly, it came back and said that it was done but could not find all the lines to modify. Is this ok?

I know it has been forever since you posted this and I apologize for the late answer, but I imagine that if you received that error you got a bad download of CM11. I've personally converted the snapshot and several nightlies of CM11 and they all passed nicely.
So for anyone getting this, if you get a similar error message: Re-download the ROM you are converting

to bad its still not possible with touchwiz, love to use f2fs on a stock rom for my sgs4-lte.
is it possible in the near future that we can use f2fs on those devices with a Samsung stock rom, using another kernel is no problem.
or is this hard to tell ?

Hello, I've been trying to use this to change my filesystem because I'm coming from CM12 and I'm trying to flash a GPE rom on my S4. But after flashing I am rebooting straight to recovery. Also I'm using the latest TWRP.

Make sure you are using a version of TWRP that support F2FS. I don't think the standard issue TWRP does. @AntaresOne has one that does support F2FS and is based on the latest version (2.8.3.0). That's the one I use. Of course, I'm hooked on his CM12 ROM as well. He does really good work!!

How to solve random reboots and other issues in Lollipop ROMs in S2 hd lte

UPDATED
Since these issues have been fixed in newer builds but as a s2 hd lte users, we have no option but to use older builds which have many issues. I found a workaround for them. If you are having wifi or other radio related issues, contact the ROM developer. This post can't help you. Flashing latest baseband helped me and could work well for you as well. Lets talk about two of the most common bug that haunts our device
1 Apps auto closing->( only for LMY48G builds,if you have newer builds,just flash gapps and reboot. to check go to about phone-> build number)
This is a webview related bug.
Download latest gapps from opengapps.org.
I prefer aroma installer as smaller packages don't have webview included,which will make the bugs worse.
Flash gapps. Dont forget to select 'android system webview' from the aroma installer.
Download the zip file from the
link
https://mega.nz/#!0d5Tiaja
Decryption key !JAG5Im-T75YN1CKIOiOcyDDaBH2ILD6dzwxw4xnhrBc
Extract "libwebviewchromium.so" and "libwebviewchromium_plat_support.so"
It is taken from stock samsung ROM and only works on armv7 devices.
Copy them to /system/libs using ESfile explorer or any other root explorer.
Overwrite the original file if asked.
give permission (-rw-r-r) to both file
Reboot to recovery
Flash this file "cm12.1 android system webview" from this thread(only for cm12.1, will cause bootloops in Xenon hd and resurrection remix)
http://forum.xda-developers.com/xperia-m/themes-apps/mod-google-android-webview-t3109216
Apps will now no longer auto close in your face without warning
((-> After testing for a month, I concluded that these steps are optional and use only if you want to have google android webview instead of cm12.1's built in 'android system webview'))
2) Now the most important part, random reboots.
This was reported on earlier builds of lollipop by many users.This is mostly caused by minfree that android uses to manage memory. If you navigate to sys/modules/lowmwemorykiller/parameters you can see 4 or 5 files. two of those files have wrong permissions. They are "adj" and "minfree".
If you give them (rw-r-r) permissions, you can adjust minfree values. the stock values are too aggressive and would cause constant reboots, freezes. Download romtoolbox, navigate to task manager, swipe left. you can choose to use any presets. i use 8,12,24,60,70,80 as minfree values.
Dont check "auto apply on boot" because you need to repeat this whole process after a reboot as those two files"adj and minfree" will be replaced from boot.img on boot by kern
Permanent fix: unpack boot.img. Navigate to ramdisc and open init.rc file in notepad. Find the line
chmod 0220 /sys/module/lowmemorykiller/parameters/minfree
chmod 0220 /sys/module/lowmemorykiller/parameters/adj
Change both values to 0644
save and close
Repack boot.img
Put it back inside the zipfile using winrar or use flashify from playstore to update boot.
I found tool to unpack qualcomm boot.img from this website. Full credits to the developer who made this tool.
http://www.droidbeep.com/how-to-unpa...-img-qualcomm/
download ROM toolbox and apply your preferred values
3. Low storage and optimizing apps(configuring ART compiler)
After google updated android runtime from JIT to ART, apps take up huge space and "optimizing app" takes forever. But there is workaround for that too.
1)Open build.prop in any text editor.
2) find these two lines:
dalvik.vm.image-dex2oat-filter=........(blah blah)
dalvik.vm.dex2oat-filter=...(blah blah)
3) Change both of these lines to
dalvik.vm.image-dex2oat-filter=speed
dalvik.vm.dex2oat-filter=Verify-none
If these lines doesn't exist, in your build.prop,you have to add them manually
4) save your build.prop file
5) reboot to recovery and wipe dalvik cache
After this check your storage space, You will have plenty of storage left and optimizing apps should be faster. It works just like old JIT compiler from older android versions.
if this doesn't work for you, you have to edit these same lines from default.prop by unpacking boot.img

I have fixed this issue by editing init.rc inside boot.img, but i dont know if i should post it here or not.

You can try wiping phone efs through odin in order to fix radio issues
1 Download stock jb rom
2 Check "phone efs clear". This is most important.
3 Click pda
4 click start
5 wait for phone to boot up
6 go to settings->software update to check if you are running latest jb build. Soft reboots and radio issues are usually caused by old baseband version.
7 Proceed with usual old way to install lollipop.
This way odin will wipe your efs settings to rebuild from scratch.

still ploblem ??? :? wait how to clear efs
at first time i have checked this box but failded ,

you need Stock jb rom to do this. I also had this issue in e120l, but clearing phone efs fixed radio issues for me. you need odin3v 1.85 and samsung usb drivers.
You can find it alongside " phone bootloader update". Be careful not to select this one by accident.

you get "libWebviechromium .so" file while installing gapps package. Go to opengapps.org and download aroma installer.
there are two files in the archive i uploaded, libwebviwechromium_loader.so and libwebviewplatsupport.so. You need to extract and replace those files in system-> libs after flashing gapps package. The built in webview will cause random apps shutdowns. this file is critical. You need libwebviewchromium_loader to start webview app. your system will not function properly without it.

have you checked debugging option from developer options before doing this? Make sure your data cable is not faulty. please make sure you have a backup of efs partition if you are having network issues with all ROMs. try hellcat and stock based roms for testing to make sure you are not having this issue only on lollipop or kitkat. Also try to wipe boot from recovery menu before flashing.

TWRP, ROOT and disable Encryption for Yoga Tab 3 Plus (YT-X703F/L)

TWRP is an open source, community project. TWRP development is done by roughly 4 people at this point. We also have a large support community with many people who are willing to answer questions and help people with their devices either through our IRC channel or on forums like xda-developers.
Team Win was originally formed to work on porting WiMAX to CM7 for the HTC EVO 4G. After our work on the EVO 4G we wanted to work on a project that would work on more devices than just the EVO 4G and we settled on working on a recovery. Today TWRP is the leading custom recovery for Android phones.
A custom recovery is used for installing custom software on your device. This custom software can include smaller modifications like rooting your device or even replacing the firmware of the device with a completely custom "ROM" like OmniROM

WARNING!!! Be careful what you do here. One mistake and the device is soft-bricked. I take no responsibility for bricked devices, lost warranty or even OTAs not working!! Booting and/or flashing files from this post is on your own risk.
Requirements
Unlocked bootloader
Yoga Tablet 3 Plus with and without LTE (YT-X703L and YT-X703F) are supported
Known Issues
WARNING! Our device uses dm-verity (verified boot). The system partition should remain read-only. Otherwise a bootloop will occur. You can flash my modified kernel or SuperSU to resolve this but OTA's are no longer possible! You have to restore a factory image or clean system backup to receive OTAs
Potentially DRM keys are lost! Pure unlocking and rooting does not cause the issue. However, there have been reports of lost DRM keys by some unknown action. It is advised to act with caution. Losing your DRM keys can lead to issues with some apps which use DRM which could then have limited or no functionality. E.g. Netflix will only stream in SD (480p). You can check with DRM info if you still have L1 security level which means DRM keys are intact.
Download
Official TWRP for YT-X703F (Wifi): twrp.me
Official TWRP for YT-X703L (LTE): twrp.me
Instructions
Install fastboot and adb on your PC, e.g. from here
Enable developer options and in there select to unlock your bootloader by enabling OEM unlock and enable USB debugging
Connect your PC to your tablet and run
Code:
adb reboot bootloader
using adb on command line. The tablet will reboot into bootloader mode where you will only see the Lenovo logo. Now you use
Code:
fastboot oem unlock-go
to unlock. This will factory reset your device
Setup the tablet again and reboot again to the bootloader
Then run
Code:
fastboot boot twrp-3.2.1-0-yt_x703f.img
to temporarily boot into TWRP. You can also flash if you are sure
Select to keep system read only when TWRP starts to avoid modification which will make OTAs impossible
Optionally flash SuperSU or Magisk in TWRP which should install system less. Keep OEM unlock enabled if you flash or modify anything

System Updates (OTA)
In order to successfully apply Lenovo system updates after root you have to restore the original boot, recovery (if you flashed TWRP) and system partitions from your current installed version (e.g. S000744) for your variant of the tablet. This will NOT delete your apps and data but will unroot. Note that OTAs are block based and always check the contents of most of the partitions. This means that all of these partitions (except your data) have to be original and have to be on the exact same version (e.g. S000734) for the update to succeed.
See here for instructions how to restore the partitions with fastboot.

Thanks buddy! You are an absolute champion! Tell me what you need me to do and I'll do it before rooting and up load what you need.

Doing good work here.
Who wants to bet on a race between matshias and Lenovo support for who can fix the issues with this device first?

That's great and fast, I'm thinking tab 3 plus is getting hot now.

Great to see there is something moving for the yoga now. You think it will support the lte Version anytime? Or maybee even lineageos?

so you know, i've managed to install xposed thanks to this thread https://forum.xda-developers.com/xposed/unofficial-systemless-xposed-t3388268 and is working well.

Well if you haven't modified anything yet then it'd be great if you can boot into TWRP with system read only and then connect via ADB to the tablet with a big SD card inserted which has enough free space (4 GB).
The run the following command
Code:
dd if=/dev/block/bootdevice/by-name/system of=/sdcard1/system.img
This will take a while. Then copy the file system.img from your SD card to a PC and zip it (or 7z, rar). Then upload it

The LTE variant is probably very similar and it wouldn't be much work. But I don't own the device, so I would need some help. So someone with the LTE variant who is not afraid to experiment with fastboot and adb and who can provide me with the details needed I am happy to compile a TWRP for it.
LineageOS is much much more work than TWRP. For an experienced cyanogenmod/LineageOS dev it is not much of a thing and would take only a few days, especially since it is a Qualcomm device and there are already ports for devices with SD 652. But for me this is new as well so it'll take much longer. As soon as I have time I'll look into it.

You forgot to tell me to go to adb shell :silly:
DD is currently doing a dump, non interactive so I hope it is still alive, it has been close to 1 hour so far. I will upload the clean image once it is done and await further instructions from you. :good:
I'm in Perth, Western Australia (UTC +8:00), so we might be playing timezone tag.

I think I forgot one more thing. The external SD card needs to be mounted in the TWRP menu. I believe it's not mounted automatically. So the DD command does nothing. It shouldn't take that long. Sorry about that!

I was wondering why nothing was happening after 3 hours.
I have rared it and it is uploading at the moment, it is going to take 5 hours.

If that's real it would have saved me a lot of time finding the loophole in the system to extract the boot and recovery image. But still a great find which will rescue some soft-bricked devices.
