Slow/Dirty EvoX Fingerprint Recognition Solution:

I almost left this ROM due to the bad/slow/dirty fingerprint reading i was experiencing that i didn't have on OOS stock. I have finally figure out why and corrected the issue by flashing a backup copy of my persist.img i had from OOS OB4 then deleting the fingerprints and then adding them back. The fingerprint recognition is super fast, and never complains now!


In ADB Shell, enter this command to backup a current copy of the Persist partition (just to be safe)
dd if=/dev/block/bootdevice/by-name/persist of=/sdcard/persist_EvoX.img

Move that from your SD card to a safe storage place.

Note: If you don't have a good persist backup, flash back to STOCK OOS that the fingerprint works good with and use the method above to save a good copy of persist.

Now restore your good Persist image you made or already had from OOS 11:

While on EvolutionX ROM using fastbootd (you MUST be in fastboot D):
fastboot flash persist persist_backup.img

Just reboot after flashing, then delete your fingerprints and re-add them back.

I am currently also considering switching back to a/this custom rom, but it bothers me a lot that the fingerprint problems are present on all custom roms. If your solution works it would be sensational. Therefore my question, could the developer directly the "persist.img" of OOS in the Rom plant?
Second question: has anyone tried this step and can confirm that it works?
Thank you.

Worked great for me. FP was basically as fast as OOS after doing this. Only reason I went away from this ROM is the fact AOD doesn't turn off with proximity sensor in pocket / wallet cover. Every other ROM does this but even with pocket mode activated the screen just stays on 24/7. Very burn-in intensive and wastes battery like mad.

DotOS and CrDroid both turn off AOD just fine in pocket for example.

I can'n install room v5.8 on 8T- because error 7.
1- flash recovery 8T
2- format factory
3- apply adb sideload room--> flash 47% error 7
Can guide me? Thank

Download the ROM and the payload dumper tool. Extract the fastboot files from the downloaded ROM using the payload dumper
Login to fastboot and run the following commands

fastboot flash recovery recovery.img
fastboot flash boot boot.img
fastboot flash dtbo dtbo.img
fastboot reboot fastboot
fastboot flash odm odm.img
fastboot flash system system.img
fastboot flash system_ext system_ext.img
fastboot flash product product.img
fastboot flash vbmeta vbmeta.img
fastboot flash vbmeta_system vbmeta_system.img
fastboot flash vendor vendor.img


Or download the attached zip. It will have the payload dumper as well.
1)Download ROM
2) Copy the payload.bin file from the ROM zip to payload_dumper/input directory
3) Run payload_dumper.exe
4) FIles will be extracted to payload_output
5) Copy those files to the fastboot_installer directory
6) Run ROMinstaller.bat

Failing at 47% is normal. Did you actually start the phone afterward?
For me it didnt even start installing. I got a similar error (dont remeber the exact one) like "error applying update 7 kinstalldeviceopenerror " and it failed. But i didnt actually start the phone.

Tried with the recovery mentioned in this thread and also with LOS latest recovery, gor similar error. so went with the payload method.
