F2FS problem - CM 12.1 - TWRP v 2.8.7.0
Hi.
Would like to format data & cache to F2FS, and have tried following the guides available.
However, when I want to format TWRP doesnt give me the option to use F2FS, only the other five filesystems.
Any ideas ?

Then you have a non f2fs compatible twrp build

Hi,
I have installed custom ROM and apparently it converted my userdata partition to F2FS, because when I try to install any other ROM it fails after checking userdata filesystem type. TWRP doesn't boot as well, I only have CM recovery working. I'm looking for someone who can help me write updater script to format the partition back to ext4 using mkfs.ext4 which is included in recovery. Please help.
Installing custom TWRP with f2fs support from here helped.
Does anyone have encountered this issue?? It's really damn annoying... Thanks for any help
I did have it and it is very annoying, I installed TWRP Blue Spark and it solved the issue. I will look for it and if I find it I will share it with you.
What version of TWRP are you using? 3.0.3-1, 3.0.4 and 3.0.4-1 have all been working well so far.

This happens if yu are f2fs formatted and swipe in allow for modifications when booting in §TWRP. If you don't swipe, you can still flash roms. Not sure what's changing anyway...I formatted ext4 and have no issues right now.
iam using f2fs with latest twrp (3.0.4.x) and no such issues.
but i was losing apps randomly after booting into recovery, on older TWRP versions.
Installed TWRP 3.0.4 and everything seems back to normal. Thanks for ur help guys.
Now my next problem is 4g reception in France..
Cheers thanks a lot
PS: how do I know if I'm using f2fs or ext4?
I believe there was an option somewhere in TWRP to view all your partitions and their file formats. By default, only the data partition is formatted in f2fs, everything else should be ext4 (and maybe fat?)
Edit: If you select Wipe in TWRP, then advanced wipe, and select the Data partition, you can click partition options to see what the file format is (don't swipe right if you don't want to wipe it). Aside from data, every other partition should be ext4 by default.
There's also apps like disk info that can tell you the file system used as well.

Hi,
I made this guideline for those who want to convert filesystem from EXT3 / EXT4 to F2FS on lavendar, for amazing speed & performance.
I already had MIUI EU beta working on my phone.
Note: Internal data storage will be wiped. Make sure to have a backup.
Steps:
1. Install Orange Fox Recovery (latest one)
2. Reboot to recovery
3. Go to Manage Partition
4. Select "Cache" and click orange tick button, then choose F2FS as the file
system and proceed.
5. Again, select "Data" and click orange tick button, then choose F2FS as the file
system and proceed.
6. Reboot to Recovery again.
7. Install a custom kernel which support F2FS (i.e Evira)
8. Install Universal F2FS support patch file. (otherwise causing boot loop)
9. Reboot
Enjoy the speed.>>>>>>>>>>>
Hi! Filesystem F2FS keeps always even if you make full wipes + format data? For example, if i do the process but later i want to change my device's ROM, system will still have F2FS after wipes and format data? Sorry i've never changed my device's Kernel so i don't know if the system keep the new kernel (and the F2FS support patch file mentioned in this post) after a wipe + format data or they have to be re-flashed. Thank you in advance.
Did as instructed. got a boot loop : (
Are you sure that fstab flags are properly set? I don't see 'nofail' option or maybe there's some other option that substitutes?
I use miui eu 9.8.9
I reformatted back to EXT4 and it boots again.
If you are not so sure (neither am I, I will go research mount command options) then I recommend 3 separate zips
One that's F2FS only for cache and data
One that's all EXT4 for cache and data in case someone needed to revert without reflashing rom
And one that's F2FS cache and EXT4 data because migrating data partition can be a lengthy process for some people. But formatting cache is always easy.

I had the same problem, to solve it do the partitions process, flash first evira, reboot to recovery again and flash the patch. It worked for me and booted succesfully into the rom. I use xiaomi eu 9.8.9 too.

So I do it like this?
1- change partition fs
2- reboot into recovery
3- flash evira
4- reboot into recovery
5- flash fstab.zip
6- reboot into rom
Is there actually any benefit at all in using F2FS on Lavender since the flash type is not one of ones supported by F2FS?

What do you mean when you say that its flash type is not supported by F2FS?

See, F2FS works on NAND flash memories.... Lavender ilis NOT a NAND flash, so there is no advantage in using it. At least this is the rationale if I am not wrong.
As speed goes, F2FS is no benefit as your link said, but also for the wear and tear there is not much benefit

Hmm? according to mi website and wikipedia it uses eMMC 5.1 which is a NAND storage. why wouldn't it work?
As for my link they all agree that F2FS is a bit slower for read but hellalot faster for write. overall gain is considerable.

No, the data partition will be converted back to ext4 everytime you do "format data".
Not formatting your data could keep the f2fs status, but it's risky to not formatting data when changing ROM in lavender due to it's strict encryption issue.

Miui.eu ROMs doesn't fully support F2FS. The rom does, but the kernel doesn't.
You need to make sure both the ROM and kernel has F2FS support.
if one of them don't, you'll get bootloop.

I've been on F2FS since.. April I think, and I've installed and tried so many roms without any problem.
here's what I normally do and it works all the time:
- Make sure data & cache are ext4
- format data
- reboot recovery,
- wipe cache, dalvik, system, data, internal,
- flash firmware
- flash ROM
- flash gapps (optional)
- flash magisk
- flash kernel that has f2fs support (optional, if the rom's kernel doesn't support F2FS)
- reboot system
————————————————————————
it's necessary to install the rom in EXT4 because automatic encryption doesn't work in f2fs partition (I think... based on my experience). granted, you can do the encryption manually from settings, but it's require to have 80%++ battery and the more stuff you have in your internal, the longer it'd take to manually encrypt the device. automatic encryption is just easier to do. You can leave your internal decrypted as well, but you won't be able to use your fingerprint or any screen lock methods. That's just how redmi 7 family works.
————————————————————————
- once you get into system, reboot to recovery once again
- convert cache & data to f2fs
- flash magisk
- flash universal f2fs patch
- reboot
now your /data and /cache are in f2fs.
If you're already on a rom and kernel that support f2fs, you can just do the later half of this tutorial without the need to reinstall rom and everything, but you'd lose all your data. good luck!
What's the benefit of changing cache into F2FS?

Thanks
thx for guide.
Which custom rom that support f2fs?
I just did a full flash and erase with sweet_global_images_V13.0.12.0.SKFMIXM_20220801.0000.00_12.0_global ROM.
after a quick rom setup with no sim and no wifi, I went back to TWRP and the data partition can't be mounted.
I tried then the usual advanced wipe, setting the partition to ext2 then to ext4 and the rom does not boot and goes back to recovery.
If from recovery I do a wipe, then the rom starts, but after setup, going back to TWRP gives agaion the same problem and the data partition can't be mounted.
Any Idea?
which TWRP version you use?

Have you format data partition before starting the new rom?
Format is neccesary to remove the encryption of the formal rom.
Wipe data isn't enough for that.
yes I did... but I think MIUI reformats it.
which twrp are you using?
Maybe the twrp you're using doesn't support encryption yet
it worked with MIUI 12.5.9.. but MIUI 13.0.12 reformats the userdata partition if it is formatted with twrp.
maybe because of dm-verity but I am not sure.
I just did this:
FULL FLASH from EDL or FASTBOOT without relock and including userdata.
Then fastboot boot twrp-3.6.2_11-0-sweet.img
Form TWRP I reformatted userdata as EXT4.
Then booted the system... after booting for the first time the system, userdasta is again encrypted.
Yes, seems u are using twrp which not support decryption yet, change ur twrp/ofox then (there is 1 that already support android 13)
