Hi there,
I searched a lot on the subject, but I'm still not sure if/how this would work:
Can you install a factory image or an OTA update on a F2FS formated Nexus 7 2012?
Currently I have a lollipop custom ROM and kernel, with all F2FS and TWRP running on my Nexus 7. Could I install a custom F2FS kernel on my F2FS formated Nexus 7, like Phantom, and then only flash system.img and userdata.img from a lollipop factory image? Then, could I simply flash future OTA update zips?
Thanks!
It will just format it back to ext4. I've been trying to get f2fs to wepork on mine but I can't get the damn thing to recognize and side load. So I keep having to reflash official builds and it just rewrites everything to the stock build. I flashed the whole thing as f2fs wiped the device.

Hi,
I got as far as (in short):
- Flash factory image
- Flash openrecovery TWRP
- Backup system and data (you have to make some space on system first, e.g. by moving some apps over to data)
- Format system, cache and data to F2FS in TWRP
- Restore system and data backup with "Use rm -rf instead of formatting" checked in TWRP settings
- Flash boot.img from Phantom kernel
I got this to work with LP 5.02, but for some reason with 5.1 the system restore failed so far... As for updates, I thought that, in the same way, you could just restore a system backup of a newer factory install over your actual system, but I haven't tried that yet.
Then again, this all is quite tedious. I'm not very advanced in img or ROM modification, but I'd like to know what one would have to modify in factory images or ROMS to make them F2FS compatible. For JB there are ressources out there, but I haven't found anything for LP so far... Anyone?
All I did was on 5.1 flashed a F2FS kernel then in TWRP formated cache. It was like night and day.
Simply formating cache to f2fs makes already such a difference? Interesting, will give this a try. This would be a fairly easy solution to have a fast stock experience. I might try formating data to f2fs as well (and restoring backup), but leaving system on ext4. This way you may be able to simply flash the system image from future factory images to update your system, that would be a good enough solution for me.
First try updating to 5.1.
5.1 is running and performing so much better than on 5.0.2.
Even with ext4 filesystem and stock kernel.

I already am on 5.1. Intitially it ran pretty good indeed, but I'm starting to get occasional lags again now. Not as bad as before, but still not as smooth as with JB when it was new... Like I said earlier, I haven't managed to do the TWRP f2fs backup and restore method for some reason with 5.1, but keeping system on ext4 might do the trick, so I'll try that and see if it improves upon stock 5.1...

Hey rbeavers, what kernel did you flash? I tried with Phantom Kernel r1 and r2, and I get NFC force close at startup, which prevents from using the tablet...
Thanks.

I'm using Franco Kernel(r82). It supports F2FS(formatted /cache and /data to F2FS) and it works flawlessly.
TWRP backups fail on stock 5.1 with f2fs/franco?
I downloaded the 5.1 factory image; installed it using the included batch file; installed franco r82 and formatted /cache and /data to f2fs. It seems to run reasonably well, but TWRP 2.8.5.1 and 2.8.6.0 both fail to make a backup, giving an unspecified error when backing up the data partition. Do you experience the same thing? Do you know of a workaround?

Franco Kernel(r82) sorry so late.
Still working great! Only gripe 2 - 3 second delay on waking up.

Running really good so far with Franco Kernel and Cache and Data in f2fs. Thanks guys.
I also don't get that wake delay btw. Maybe wipe cache again?
@CCarson: I made a successful backup using TWRP 2.8.6.0. Maybe backup your sdcard and then re-format data. Also, don't know if this applies to you, but if you have the 16GB model, the 5.1 factory image formated mine to 8GB, so I had to re-format data once to get it back to 16GB and only then I changed it to f2fs.

I'm sorry if this has been asked, but I have looked and am not able to post in the developer thread yet. I've got everything up and running on my N7 with f2fs, but I'm curious now if I update my ROM do I have to go through all the steps again? Do I always need to format data at the end and lose everything? Should I be using titanium backup to solve this? Hopefully someone can help me out.

If everything is up and running on F2FS already, you can flash and restore titanium backups as normal. You just now have to make sure the ROM and/or kernel you're flashing supports F2FS or has been converted to support F2FS.

I am already on Carbon Rom All-F2FS, should I switch to another F2FS rom, what wipes are necessary? And should I format my tab again to all F2FS?

Just do a normal clean flash like you would if you were still on ext4. No need to reformat. That's how i switched to Carbon. As far as nightlies on Carbon (or others), just dirty flash them. I've had no problems doing that.
Hello folks,
Well, we all know that the stock Moto G filesystem is F2FS. But surprisingly, the Moto G GPe has a native Ext4 support. Since F2FS is supposed to have about a 30% better performance, I decided to try out the convert to F2FS feature in Philz recovery. So I formatted my system and cache to F2FS (since it didn't give me an option to wipe data and data/media to convert) and flashed a ROM. Currently, I seem to be facing a bootloop.
Anyway, has anyone else tried something like this? If yes, then please share your experience here.
Cheers.
It would be great if that would be possible,then you could jump from retail stock to GPe more easly. I have an XT1032 stock rom and i'd really like GPe,but my concerns are that would i be able to stock XT1032 again from GPe? You know,for F2FS and if i wanted to flash custom roms again to have better support. Any thoughts on my question? And look the first post,this is really interesting since if you'd want custom roms and you are on GPe,you wouldnt need to flash stock ROM to avoid bugs with custom roms and GPe
TWRP also include a format to f2fs <-> ext4 option:
Add GUI option to change or repair file systems on individual partitions. The change is destructive so backup your data including internal sdcard first. This option should make it a little easier to migrate a device from ext4 -> f2fs, for instance. You will find this option under Wipe -> Advanced Wipe, then select only one partition and then press the Repair or Change File System button. If a developer has added f2fs support for your device and we don't have it in TWRP, please contact me via PM to arrange for it to be added.

U need a kernel support somewhat like this in nexus 5 for f2fs
http://forum.xda-developers.com/google-nexus-5/orig-development/nexus-5-f2fs-t2668486
Stock kernel supports f2fs, GPE kernel does not. Development of a GPE kernel that supported f2fs would be ideal, assuming the GPE stock ROM also functions correctly with a f2fs formated USERDATA partition.
Has anyone even tried to flash boot.img from stock,and then converting in philz?

/boot/ (kernel+ramdisk) does not need to be formatted. Flashing boot.img before or after wouldn't make any difference.

Well, I tried using TWRP, but it ended converting my phone back to dual sim.

Using TWRP to reformat 'data' from f2fs to ext4 wipes SDCARD and didn't even change the format. Right now it appears if you plan on moving between GPE and non-GPE and possibly back again, keep a full firmware image for both.
EDIT: Actually it appears TWRP did format correctly. But the GPE kernel can't get past the Bootloader. Perhaps there are other partition table differences.
After another try..the following works fine.
Migrate to GPE:
1) In TWRP, wipe, and format 'Data' from f2fs to ext4 (this will wipe internal storage.)
2) Sideload / adb push GPE ROM or flash ROM and Kernel via fastboot.
3) Reboot
Return to Motorola Stock:
1) In TWRP, wipe, and format 'Data' from ext4 to f2fs (this will wipe internal storage.)
2) Sideload / adb push Stock ROM or flash ROM and Kernel via fastboot.
3) Reboot

I re-read your OP. The GPE Kernel expects the 'userdata' partition to be ext4. Unless someone develops a custom kernel to support it; you will never be able to run the GPE ROM with an f2fs 'userdata.'
Because you set all partitions to F2FS. Only need to change /data to F2FS. Leave system and cache ext4. You would need a ROM with a patched fstab and then a kernel supporting f2fs for system and cache to be in F2FS as well. Plus major benefit is in /data, not system and cache. I tested full F2FS on my N4 and it was more a pain with less gain. /data is all that should be F2FS.

You can get it by deleting the partition / data and change it later by f2fs with TWRP fastboot erase boot partition and flash the boot.img from the stock 4.4.4 rom motorola everything from GPE and I have it so it shows more fluid
I converted a stable version of cyanogenmod into f2fs format. Everything was going well until I accidentally updated it and now it just sits on a bootloop. Anyone have any ideas how I can fix this without wiping. No i didnt get to create a nandroid.

The update you installed likely reformatted your system and cache partitions back to ext4. Try reformatting them and reflashing your ROM.
Alternatively, you could also try just flashing an f2fs-compatible kernel first to see if that gets it booting for you. That may be all you need if /data is still formatted as f2fs.
Did you used TWRP to convert to f2fs ?
Hi,
I have a 16GB Nexus 4, running Android 5.1.1 LMY48I. I had recently flashed Google's stock rom (Android 5.1.1 LMY48I) on my Nexus 4. Later, I noticed that my Nexus thinks my internal storage capacity is 5.6 GB, while I know it should be a little less than 16 GB. That was really strange, and I figured that re-flashing stock rom might solve the bug. Unfortunately, my phone still believes I have less storage than I actually have.
I'd be happy if someone could explain why it happened, and more importantly - How I can fix it.
Thank you!
SOVED:
I managed to fix it by formatting the CACHE, SYSTEM and USERDATA partitions, then re-flashing the stock rom. I encountered a bootloop, so I decided to format again only the CACHE and USERDATA. Everything works now.

In the future, all you need to do is boot into the stock recovery after flashing the factory image and do a factory reset.

However, as much as I know, it should be able to wipe cache and user data. I tried to flash the stock recovery, but from some reason all I got is a green Android with exclamation mark on it... By the way, I also tried CWM and it failed too.
I ended up improvising something with ADB...
I was trying to convert my system, data and cache to F2FS but after the conversion I can't use Data anymore (apparently it cannot mount data and system anymore).
Could be a problem LinkedIn to the grarak modded 3.0.2 I'm using for Exodus 6?
Any feedback is welcome!

Most probably as the official one from twrp supports f2fs natively.
I would recommend to go back to official twrp convert to f2fs properly from there and then flash the modified one, do this if you are brave enough, i havent tried this method but it should work. If all fails stay on ext4 till garak or twrp updates their twrp versions.
Thanks for you answer... I thought the same... I'll try as the new phone will come and let you know...

I got the same error for my Redmi Note 3 ... tried 3.0.0.0, 3.0.2.2, but nothing. then a guy suggested this:

and it worked. Now I can't boot on f2fs, just trying to make it work on 6.0.1 Mokee rom
