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:
http://dinc.does-it.net/EXT4_Mods/
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 Be sure to flash a newer version of the gingertiny kernel if you use a Sense ROM as the kernel version flashed to add ext4 compatibility is out of date.

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???

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.
Hey all- I haven't had enough posts to be able to post in the development thread, but wanted to post here.
CLEAN FULL WIPE- formatted all partitions (data,cache,system) wiped Dalvik cache.
Installed latest version of cyanVivo 10.1 - CyanVivo_10.1_04.24 from zip. Installed gapps gapps-jb-20130301-signed from zip.
System boots up fine. Opening camera causes gallery FC every time- wiped gallery app data.
Should I re-build Dalvik?
It is a known issue. The op is aware of it and has said he will make a fix for it. This was all in the thread, maybe page 9 or 10

Alright guys, as most of you most likely already noticed, we are preparing our device to run completely on F2FS. This task, however, needs some information and tools, which I will try to provide in this thread. It is WIP, so don't expect too much yet
First of all, we need a F2FS capable recovery. I have compiled both, CWM and TWRP, but CWM seems to have some issues, so please use TWRP for now
The only ROM running on F2FS for now is our unofficial CM11, but I will update the following list as soon as I get to know about another ROM
Unofficial CM11
To install a F2FS ROM coming from an ext4 filesystem (default), you have to do the following steps:
0) make backups (including titanium backup)
1) flash the F2FS TWRP recovery image
2) manually format /system /data and /cache to F2FS (WARNING: internal sdcard will be wiped as well)
3) flash the F2FS ROM
4) flash GAPPS
5) boot
Regarding custom kernels, if you don't use the default kernel, please don't make bug reports. If we know that the ROM and kernel are working properly, then we can go on. But for now, if you run into problems using a custom kernel, please keep it to yourself.
I assume you will want to restore your data after formatting to F2FS, but keep in mind that if you restore your /data partition via recovery, the old filesystem will be restored as well (ext4). This means, you cannot restore your old backup via recovery. However, if you have a Titanium Backup backup, you sure can restore this.

In order to compile a flashable zip, the updater-script has to be altered. But don't worry, you don't have to do this manually I edited the script creating the updater-script and made a patch, which can be found in the 2nd post

The patch in the attachment patches the updater-script (generator) to be compatible with F2FS partitions (proper mounting and formatting).
Save it inside the build dir, then open a shell and cd to the correct path. Now run "git apply <patchname>.patch" and you're good to go
Example:
Code:
cd /path/to/ROM_sources/CM11/build
git apply F2FS_updater-script.patch
cd ..
@laufersteppenwolf Ok, I'm a bit confused: according to what I'm reading here, and on your unofficial CM11 thread, I assume that /system should be formatted with F2FS using the new twrp recovery you uploaded..but reading what @Demetris and @iodak are saying on iodak kernel's thread, it seems like only /data and /cache partitions will be turned to F2FS, while /system will stay on ext4..the same has been said by @Demetris in the official CM11 thread..so, my question is: are you thinking to try developing in different ways? Just to understand where you are pointing to, and to acquire a clear knowledge about the status of your work Thank you guys!

I didn't follow iodak's kernel thread, and lately neither the official CM thread, which is why I can't say anything about those discussions. However, all the above info is still correct, as the /system partition still has to be F2FS (you can take a look into our fstab), at least up til now.
And no, I will not go a different was, as my main goal is to keep our device as unified as possible (hence also all various ROM sources on our p880-dev github for slim, gummy,...). All this F2FS stuff is still in a pretty early stage, which is why there can always be changes.

Mmm, yes, it's clear, reading fstab..thank you. The strange thing which took me asking for that question was the discussion between Demetris and iodak in iodak kernel's thread (about using f2fs only for /cache and /data) Anyway, you are the devs, so let's wait

Well, TBH, I don't know how else to describe
as anothe example, let's say we want to compile CM11, and all sources are in ~/CM11 (you ran the repo init command in ~/CM11)
DL the patch and save it under ~/CM11/build, named F2FS_updater-script.patch
then run the following commands in your terminal:
Code:
cd ~/CM11/build
git apply F2FS_updater-script.patch
then you can compile the ROM as usual, but make sure to run repo sync before applying the patch

Hi Revered Developer:
Two questions into one: Is it really worth formating F2Fs, which seems to be yes with a lot of buts, and should we choose Art selected runtime. The ART problem is theoretically ok, better than Dalvik, pratically every time I turn Art on, benchmarks ans subjective feeling od the device got worst: Nexus7Flo and t0lte Note II. We need Xposed installer and surround environment...

using twrp where can i find the option to format /data and /cache to f2fs?
edit: found it, under andvanced wipe
Roms with data and cache f2fs while system ext4
If I have non all-f2fs rom. Can I install it with only data and cache f2fs
Because CM11 is all-f2fs and other roms are not, but @iodak released kernel that is compatible with different f2fs and ext4 combinations.
So what roms I can install with data and cache f2f2 while system is ext4
I'm really confused with this :silly: :silly:
Every normal rom (ext4) can be installed with data or/and cache on f2fs. And you able to update or change rom without problems.

Dear Community,
I tried today the new (last) Version of the LiquidSmooth ROM. I saw that Laufersteppenwolf is providing the nighties since 28th July.
Many many thanks to both of you guys! Great work.
Unfortunately I still can't write in the official thread:
http://forum.xda-developers.com/showpost.php?p=54480429
So I've to post my issue here. Hopefully anybody can help me.
Actually I've the exact same issue as KhaledAbdo had:
I am facing some weird behavior now ..
I have setup twrp 2.7.1.0 F2FS recovery .. formatted everything, set Data and Cache to F2FS and left system to EXT4
then I flashed the latest LS F2FS ROM with PA Gapps ..
on this setup, rebooting the phone will just show the LG Logo .. and before the bootanimation, it'll just shutdown .. !
2nd trial (bit off topic):
I then tried flashing iodak kernel, but it detects that all partitions are EXT4 .. although twrp sees that Data and Cache are F2FS ones .. so, it formats data and cache to EXT4 again ..
I tried formatting many times .. but nothing helps ..
thanks in advance for your help ..

But without "PA Gapps"!
The strange think is, if I install the iodak kernel it works fine and the ROM is starting.

Hi, I don't post much on here but I wanted to share something with everyone since this is one of my fav tablets (before one of my drives crash and the data is lost, lol).
Disclaimer: I'm providing this AS-IS, I've been using this for about a few weeks now and while there may be bugs, it's been working for me and figure I'd share a newer version of TWRP for the TF701T. This will need some testing, I haven't tried flashing a newer rom - just using a "dirty port" of Remix OS I'm using (SK1WG base).
Hopefully this helps someone who loves this lil tegra transformer as much as I do!
I'll post links to source later on but to build this but if anyone wants to try;
-I used a slightly modded version of the zombi-x device tree
-tweaked the rm-wrapper (from the timduru katkiss device tree) so it references the correct includes (I was building under zombi-x 5.1 using omni twrp 8.x)
-Since the device tree was already using a prebuilt kerenel, I plugged the one from the TWRP 2.8.x kang/area51 by sdbags release
-The "rom base" folder I was building under was "zombi-x" 5.1/LP
-and the TWRP sources were from omnirom's oreo/8.x source
Here's a link to my dropbox tf701t folder, I keep a backup in the recovery folder.
I also built a 3.0.0.0 "area51" version, think I found that in the zombi-x repositories also. Both booted, roms I had installed, backups were made and restored under both however I've used the 3.2.1.x version more exetensively.
DROPBOX TF701T LINK!
Anyways, happy holidays everybody! I'll try and keep up with this post and update things when I get a chance, but for now rock on!
PS. Should be able to
Code:
fastboot boot <recoveryimagefile.img>
to test it before flashing permanently with
Code:
fastboot flash recovery <recoveryimagename.img>
PS2. Added images to post for 3.2.1.0 and the "Area51" 3.0.0.0 builds, Enjoy!
PS3. UPLOADED SOURCES! (finally, lol)
DEVICE TREE
-The device tree is still setup to use the prebuilt kernel (I compiled from source posted below this, with gcc 8.x toolchain). If using the kernel source below, use recovery_tf701t_defconfig - otherwise just make sure whatever config you run is setup to use LZMA for ramdisks here.
-Also this device tree is setup to use F2FS, I left the original ext4 fstab files included with a ext4_* prefix if anyone's curious. I'll fix that eventually and split them into 2 branches (ext4-only and f2fs).
KERNEL SOURCE
-This experimental kernel has some tweaks, F2FS support (no encryption), O/C @ ~2.5Ghz, bunch of extra governors (lionheart works nicely), but in it's base form works great for booting recovery.
Hopefully this stuff helps others bulding for this awesome lil tablet! Back to some more compilations while I got time.
UPDATE: F2FS Test (12/30/17)
-Added a recovery build that I have been running for a bit with F2FS support
-Use this with a ROM that supports F2FS, or repack a boot.img with a F2FS kernel and mod the ramdisk (edit fstab to mount /data /system and /cache with F2FS.).
-It supports the usual ext4 and other filesystems, but defaults to f2fs when using the format data and wipe commands (modded fstab on /system /cache /data).
-Also haven't had any issues formatting /cache, or touch not working with this kernel. I'll get around to a normal ext4 version and upload that as it seems to fix the /cache issues.
Just here to say it all works as before and there aren't any new/strange problems. The issues with not being to format /cache and so on without going back and forth to ext4 still persist, though.

Glad it works for you too, I noticed the /cache issue also on the other TWRP 2.8.x version posted for this tablet too. One thing that I do (even on the other TWRP) is wipe the partition I want (or change its fs type) first, and if I need to touch another partition then I reboot the recovery and it works.
It's annoying, I'm currently testing building the kernel inline instead of using the 2.8.x kernel (from that other posted recovery) in the device tree. I'm using sources that I know boot, just playing with the configs to see how it plays with TWRP. I ported over the f2fs stuff from the katkiss kernel to mess around with, boots in the rom fine - so if I can get it to boot recovery then the f2fs formatting stuff should work and mount correctly.
Sidenote - one thing I notice with the 3.2.1-0 version is the screen seems to work better, I haven't had the touchscreen not responsive issue I had with the previous TWRP 2.8.x version.
Going for a coffee, I'll play around with it tonight (and remember to upload stuff to my github eventually to share). Long day of work, time to unwind
Small Update (Progress is good!)
So, took some time to dig around why it wasn't booting the recovery when I built from the same (working) kernel source I'm booting the normal android os with. Turns out, most likely due to space savings, the recovery is set to boot LZMA - turned that on in the config and that kernel now booted up recovery perfectly!
I'm rebuilding the kernel, since in my infinite wisdom, I compiled with my selinux disabled kernel - which also worked, but bombed out on any rom zips that ran anything to do with contexts/perms. Good news was F2FS worked mounting, formatting, etc.. Hopefully tomorrow I'll have a selinux friendly f2fs supporting kernel for recovery that'll work.
Random sidenote: I was eyeing the newer kernel drivers (from 4.x), If everything works as it's currently configured, I'll give try backporting the newer stuff and see how she runs. Just wanted to post a small update with some notes just in case anyone in wants to try building it themselves.
Thanks for your work! If you could manage to fix the format issues with current TWRP, that would be excellent. I've never been able to dirty flash due to this pesky recovery problem, I always have to go back and forth to ext3 -> ext4 and then flash clean and restore my apps .. quite a bit of time waster.

I need to reformat /system and /cache only - most times. No need to reinstall apps.
You're lucky then, I always end up with errors on dirty flash and format /data also fails, so I resort to changing FS. Sometimes even this gives errors and I need to do it several times until errors are gone.
I just restart recovery and try formatting again.
AmauryRR great work! Please use the memory card of the docking station
Sorry for offtop, but... I saw on your dropbox remixOS. Where I can find info about how to install it? Main theme on tf701t about remix os is not having this. (or i am blind).
I haven't tried flashing a newer rom - just using a "dirty port" of Remix OS I'm using (SK1WG base)

Can you, please, describe how it is working?

Yes, please, more info on that!
Tf701t update
Hi AmauryRR,
Any chance you could break the process down step by step for none-IT people like me? i have tried everything but think i have to accept that this is above my pay grade .
i am especially having a difficult time with the boot loader. Indicates the following: "An unknown error occurs, which may be a network......try again later"
i can email you the screenshots as i can't seem to upload them here.
regards
rob
Can someone get me recovery work in android 4.2.2 ,
10.14.1.47 bootloader please?
"" I searched in google all recovery file can't be downloaded''
Any chance of a flashable version of this?
