Yes. Because to my knowledge there are no kernels that support f2fs and force encryption. The main kernels I know of that support it are no-force encrypt.
[UNOFFICIAL] [07/19] TWRP 3.1.1 with F2FS support
- Thread starter nathanchance
- Start date
Is is the kernel that has to support it? Would be amazing if someone could add it to their kernel. Not running encrypted will have to do for now though. Snappier phone effects my daily, while not being encrypted might maybe affect me once if I'm unlucky.
Version 3.1.1-8 now available!

You can encrypt your phone at any time on any kernel, these kernels just don't FORCE you to be encrypted.
For what it's worth, I tried to force encrypt with f2fs yesterday and it did not work. The primary reason being that it formats data to a dm block device and the tools to do that expect an ext4 image. I'm sure there are ROM side commits to support force encryption with f2fs but I haven't looked.
I still seem to be having issues restoring an adb backup I made with this latest version just recently. It says that it restored System in 0-1 second and just hangs there.

thanks man. Any tips on how to do clean update on PureNexus when I am already F2FS?
Should be the same as any other clean flash... Except a custom kernel is required, rather than optional.
Have a good one!
as has been stated, it's pretty standard.
just make sure that in settings the option for "Use rm -rf instead of formatting" option is checked so you don't accidentally reformat which could put you back to Ext4.
Hi.. @The Flash

5/12 TWRP Recovery Issues
Grand Masta Flash...
1st and foremost I want to thank you for all of your support and AMAZING work you've done for this wonderful device... You have truly made our experience far superior to what it could have been (AKA STOCK)
I have been running your divine Flash kernel (5/1) on Chevy's latest Cortex ROM which has recently integrated F2FS support. Was, without a doubt, the BEST performance and configuration this device has ever seen. I just noticed today that you have updated your kernel and am attempting to clean format and flash this masterpiece but unfortunately have received a 2 day ticket to bootloop city!
I have attached my TWRP logs and would greatly appreciate any assistance you could provide. Thank you again for all you do!

67Introduction
Hello all, this is my version of TWRP for the Nexus 6P, which includes the ability to convert your /data and /cache partitions to F2FS. This will stay inline with TWRP's changes for the most part, the changes will be listed below.
What in the world is F2FS?
From Wikipedia:
Before diving into this, I would recommend reading the official F2FS documentation to understand why this may be good for you. This is potentially unstable, F2FS is a file system that is very much in active development. There is a reason that most OEMs go with ext4 out of the box. But I digress, I am NOT here to sell you on F2FS; it makes zero difference to me if you use it or not, I am merely providing you with a tool to do so.
Changelog + differences
Differences:
- f2fs-tools bumped to 1.7.0 (Omni's 6.0 branch is on 1.4.0)
- TWRP app installation offer disabled by default
Conversion procedure
- Download TWRP from the link above
- Grab a kernel that supports F2FS (I use my own as I know it works)
- Back up any important data as this will wipe your entire internal storage
- Boot into the bootloader and flash the recovery
- Boot into TWRP and go into Wipe > Advanced Wipe
- Select Data and then hit "Change or Repair File System"
- Hit Change File System
- Choose F2FS and slide to confirm
- Repeat the previous three steps for cache
- Reboot and move all of your files back over (if restoring through TWRP, make sure to check the option to use rm -rf instead of formatting)
Bug reports
You are NOT in ANY circumstance to report ANY bugs to the TWRP team.
- If you have an issue with flashing something in TWRP, copy the recovery log to your sdcard and post it here.
- If swapping to F2FS does not stick, try formatting your data with TWRP (Wipe > Format Data) or fastboot format userdata first.
- If your phone does not boot after swapping to F2FS, either your kernel or ROM does not have proper support; post in their thread.
Adding support to ROM
In order to properly support the initial conversion to F2FS, please add these two commits to your source:
https://github.com/omnirom/android_system_core/commit/1c6700a8fb31c6e314df4f031fa23fa9178c7ca7
https://github.com/omnirom/android_system_vold/commit/c879edb2fecae709f404c2d71c1d47ceac3a325e
The reason some people have issues converting is fs_mgr will try to read the block device as ext4 and destroy the f2fs block. This commit skips that check, allowing F2FS to pass through.
Sources
TWRP is licensed under GPLv3, meaning my changes must be disclosed. I also inline a custom kernel so that source is included as well. I also add in the other repos I modify.

Checksum: http://nchancellor.net/Downloads/TWRP/angler/twrp-3.1.1-10-angler-f2fs-20170527.img.md5sum26Alright guys, new build is up. This should be much more stable than it was since it's built off of Omni's 6.0 branch (thank you so much to @jcadduono for pointing me in the right direction). Here's what's been tested and verified working:
- F2FS tools (1.7.0, both make.f2fs (log) and fsck.f2fs (log) work fine for me)
- The Nethunter kernel zip @t83wood had issues with flashing (log)
- ElementalX zip (log, boot fine for me on Pure Nexus)
- Encryption (decrypts with or without the security enabled on boot option)
Everything should be 100% good now, though if it isn't, I NEED a recovery.log (Advanced > Copy Log). Hope you all enjoy!
@chevycam94, change the zips back to the previous way they were, we now have working Busybox20Update!
Standard update, upstream fixes and such. The primary reason for this post is to notify you that your custom themes may or may not work, given the TWRP theme version has been bumped from 2 to 3. I know for a fact @z31s1g has some test themes for this here. Other than that, everything works perfect. Enjoy!
