I've been using TWRP for ....ever on my N900T (Note 3). Today I thought to format System/Data/cached to f2fs. TWRP 2.8.7.0 would only format system and cache, and only offered "Error =1" when trying to format data. By dropping down to 2.8.1.0 I was able to format data. All seemed well until I found the system and cache reverted back to ext4...probably after restoring the rom. I DID check the -rf box in settings before restoring the backup, but ...oh well.
After updating TWRP to 2.8.7.0 I went to backup the rom again, but data was not accessible. I tried repairing the file, but that was in vain also. I went BACK down to 2.8.1.0 and formatted the data back to ext4, but left system and cache f2fs. The phone seem to work fine like this, but I would REALLY like to format the data f2fs. Is there anyway of doing this with success?
The Fix.

Okay...I found that by downgrading TWRP to 2.8.1.0 I was able to format all to f2fs, restore the backup, and create a new backup. So...I'm going to stay on 2.8.1.0 until someone can assure me 2.8.7.0 or another version can perform the format and maintain the stability..

Hi guys! I need a bit of help. I was using PA 4.42 with FK r209 on my N4 with all F2FS (/system, /data, /cache). Yesterday I flashed Nexus_5_Experience_cm11_Nexus4_Release8.5 which claimed in its features that it has F2FS support. so I made a Nandroid backup with TWRP, wiped system, data, cache, dalvik cache and flashed the ROM. Installer did the job apparently fine and showed installation as successful. I then rebooted but ROM could not make it. It was stuck on decryption password screen and did not go past even by giving the password. Then I got back to TWRP Recovery mode and tried to restore my Nandroid backup but it was also stuck at PA boot animation prior to decryption password screen. Then I again went back to Recovey, wiped system, cache, data and dalvik cache again and then restored the Nandroid backup again but it stuck at PA boot animation again.
Is there any way I can restore my backup or would I need to fastboot flash a factory image to make the phone alive again? If so, would it be ok to flash factory image while having all partitions converted to F2FS? Will it do the job or add up in the issue?
Any suggestions would be appreciated please.
EDIT:
ISSUE SOLVED BY FASTBOOT FLASHING 4.4.4 FACTORY IMAGE WHICH HAD NO CLASH WITH F2FS PARTITIONS AND RE-WROTE ALL PARTITIONS TO EXT4 FORMAT.
Hello everyone,
I am running 3.0.2-2 on the SM-G935FD and for whatever reason TWRP won't wipe the encryption, thus I cant read the internal SD card. I am getting the " /data mount" error.
I have done the advanced wipe and cleared everything except the external SD, am I using the wrong TWRP? any ideas?
You must wipe data! Wipe it all internal storage!

I had same issue on G935F. Try advanced and format data in twrp. The option where you have to type yes. If not then flash stock recovery, factory reset and boot into download and flash twrp before booting into system to flash dm-verity zip.

...have you tried cursing/threatening/random acts of violence on inanimate objects? no? well BEFORE you do, advance wipe, wipe system/data/etc, reboot, or there are ways to reformat as ExFat with a PC too.
Title says it all!
I know that this should be done trough TWRP recovery but, what i need?
Backups?
Kernel with F2FS support?
ROM with F2FS support?
SuperSU can cause any problems?
Thanks in the advance for your time!
UP!
No one interested?
Ok this how i do it. It works out well for me but some get asked for an encryption pw.
Go into twrp recovery that supports f2fs
Wipe everything, format normally
Flash rom compatible with f2fs
Flash GApps
Flash kernel compatible with f2fs
Flash SuperSU
Wipe cache/dalvic
Boot into android startup screen
Reboot into recovery
Make a nandroid backup
Trasnfer nandroid backup to pc
Wipe/format again normally
Select data, then change file system, then change data to f2fs
Transfer nandroid backup back to phone
Restore nandroid backup
factory reset wipe
Reboot
Profit.
Hey guys, I was trying to flash a ROM. TWRP was unable to wipe data. It showed error "unable to mount data". So I reformatted the data partition to exFat from ext4. After that, I was able to wipe data.
Then I flashed Carbon ROM. Everything went fine but when I booted I got Encryption unsuccessful message with an option to reset the phone. I clicked reset phone, then I was booted to recovery. I tried wiping data but it doesn't work. It gives errors which you can see in the images attached.
So, can the problem be fixed using the MiFlash tool and flashing stock rom? Or do I need to manually format data partition first?
Thanks!
Nevermind, I was able to boot into twrp and then I reformatted the data partition to ext4. Then I reflashed this rom and it seems to boot fine now.

Sure, in TWRP go to Wipe > advanced wipe > select data > change or repair file system > change file system > select your preferred format.

Thank you so much. Was really frustrated with this encryption deal. Worked like a charm. Cheers :good:
So i have tried to downgrade to android 7.0 from oreo as i have replaced the screen to an unoriginal one and the touchscreen didn't work (j730f/ds.). I flashed twrp through odin and it booted up but i couldn't use touchscreen as well. so then i found older version of twrp (3.2.1-0) and it worked but it claims it is unable to mount storage. changing filesystem works only for cache and system (i haven't tried changing it for whole storage option or internal memory as i don't want to format the efs folder) and my question is what should i do now? flashing anyting using twrp doesn't work and i'm not very keen on loosing my imei.

The system partition and EFS partition are separate partitions to /data, so no need at all to touch those.
Format the data partition and it will mount.
The Format data option can be found under the wipe settings.
