Question Leave data unencrypted

[vodkinagdan]

Hello! Is there any possibility now to leave data partition unencrypted?
Tried to install miui.eu with PBRB with dfe toggles enabled - no result.
Tried to install same through TWRP + latest dfe - no result
Tried to install havoc treble + dfe - no result.
Am I missing something?
UPD
I've created DFE patch for 12.0.6.0 xiaomi.eu firmware
Original firmware is hosted here

You should replace files in original firmware with files from patch and flash it through recovery
I also flashed latest DFE(may be not beeded)

[Deprecated] Universal DM-Verity, ForceEncrypt, Disk Quota Disabler [11/2/2020]

Hi all! For the past couple of months, I've been looking into making a more universal solution to disable dm-verity and forceencrypt. Needing to take different zips, modify them for different devices, and then cross your fingers when you switch...

And latest stable magisk(may be also not needed)

If your data partition is encrypted right now, you have to format it first, then flash DFE to prevent encryption. I'm guessing that's what you did?

Yes, i did it and it was not helpfull. Seems that i've found something. Looks like I should repack vendor image with patched fstab.qcom and then reflash it through fastbootd. Because of superimage dfe patch cannot replace this file(vendor is RO even in recovery mode)
For now i've found this project, seems exactly what I need

Do we have to do this unpacking and repacking process for every new version of stock ROM?

The only real benefit I know of is being able to switch between different ROMs without having to format data - it would still be recommended to wipe it, but you would be able to preserve your internal storage between ROMs.
Theoretically there's also some performance that you could reclaim by getting rid of encryption, but on such powerful SoC any gains would not be noticable maybe outside of benchmarks.

Minor CPU performance and NAND lifetime gain. Also if you somehow clear contents of /metadata partition - you will loose all of your files on /data partition ( and internal sd as /data/media too).

Also several years earlier days I've faced a problem when new firmware can't decrypt data after previous one(it was in lolipop times as I can remember). So, if I can preserve /data unencrypted - I'll try to do so.

Do we have to do this unpacking and repacking process for every new version of stock ROM?

Seems yes, at least for now. Not for every rom, just for vendor part.
You can apply this patch to any rom based on 12.0.6.0 vendor. You'll only have to edit original dynamic_partitions_op_list file from rom archive - replace "resize vendor" string with
resize vendor 1563119616

Thanks for the work. Confirmed worked on ArrowOS build 2021.05.04. Flashing dfe and masgisk are not necessary

Thanks !!! It works !!! This is what I have been looking for...

So.... To get an unencrypted phone on Android 12 Custom ROMS you still need to flash patched Vendor?

Twrp 3.6 for 12 can't encrypt System/User data.
So to create backups one would need an unencrypted phone. Correct?

To switch between different Android 12 Custom ROMS with Userdata and system ready to flash back.

If rom is based on OSS vendor - for android 11 this patch working well now. You can try it on A12
