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 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.
Update: i Fixed it by myself. Thanks
Hello! i am new here. i have samsung galaxy s3 neo i9300i. updated to android 4.4 with TWRP installed. i wanted to flash cm 12.1 rom by "Rox". but he wrote in order to flash one need to change the partition from ext4 to f2fs which i followed but didn't find in TWRP wipe>advanced>change partition there are others but not f2fs. because of this problem i have flashed the ROM & GApps & they both flashed successfully but when i rebooted the system, download mode appears. did rebooted several times but the problem was still there. plz help me. i want CM 12.1. THANKS
WTF.... Well, guy, you needn't to convert partitions, you only have to wipe data, dalvik and cache and flash ROM & Gapps.
If you want to convert, convert only data and cache... idk why you haven't this options... Well, I never converted this files, and CM12.1 is working fine.
not working

i tried but when i flashed, its stuck in the download mode. just like Rox wrote i did that. nothing more.
Did it by myself...
The problem with my phone was the TWRP 2.7.1.0, + due to root ota updates not worked, so i downloaded another rom 4.3, flashed it, updated to kitkat (ota), flashed TWRP 2.8.5, flashed the rom (cm 12.1 by rox), flashed the gApps... now it's working... Thanks...
My phone is X720, and I have flashed DotOS based on android 8.1.0 before. Now I want to return to Android 7.1.2, but I can't flash the ROM after I wipe system, data and cache. It said "failed to mount /dev/block/bootdevice/by-name/userdata at /data: device or resource busy". I can't restore the TWRP backup of my omni based on android 7.1.2. After restoring and rebooting, it said "encryption unsuccessful"...
What should I do? Thank you very much!
I did that too, after many oreo roms, each with goods and bads, I come back to omni 7 cause it works fine.
You have to search and download the all in one tool by manforio and erase/decrypt storage after makeing a full storage backup of the phone.
It will erase everything. After that just install a stock firmware and whatever rom you want. I installed an older version of twrp to be sure it works. I think it was 3.2.1.1
if you didn't do a backup of the storage, install an oreo rom make the backup and then erase it.
The simple answer is format your storage, reboot to recovery, advanced wipe> system, data, cache, dalvik. now flash whatever you want. Warning about Omni it may be good, its kernel will destroy your battery, change the kernel and you're fine.
