Super guide: Persist file the magical file

[eduardozeassesme]

This is a guide that will help all users who have problems with WIFI (bad mac address), bluetooth, sensors, cameras and everything related to the part of the hardware malfunction of our device in this case of POCO F1 (also It can work on most phones with Qualcomm processor but persist.img file and twrp are diferent, search on your device thread for files) when moving from one ROM to another: From MIUI to AOSP or vice versa, or from AOSP to AOSP.

Requirements

1. It is mandatory to have the bootloader unlocked
2. Being in some AOSP rom based on android 9 or MIUI, in Q the WIFI works normally (something strange lol)
3. Use the recovery (TWRP) found in the attached files
4. Use the persist file that I am going to attach

Steps
1. Install the attached TWRP
2. Start in TWRP
3. Conect device to PC and put "pocopersist8.img" on internal memory
4. Go to install, select IMG option, select persist file "pocopersist8.img" and install on persist partition
5. Reboot your SO and check

This caused me problems..

I flashed this and then noticed the phone took longer to start.. Then today I was watching youtube so I switched to auto rotation and I was shocked to see rotation still locked.. so I restarted and was on 15% battery and after restart it jumped to 40%.. the reboot didn't fix the problem so I entered CIT to check hardware and found out that the proximity, accelerometer, gps, gyro, magnetic sensors aren't working..

I was smart enough to have taken a backup before flashing the persist image.. I restored the backup and everything was fixed.. battery became 15% and boot was fast etc.

I have the global version of pocophone.. I think this isn't compatible..
if you want to fix any issue just do a fastboot flash of stock rom but keep bl unlocked..

Hello! I would be very grateful if you could help me. I have problems with camera software on my POCO f1. If we look at MY camera device info, we can see that camera id, resolution, focus mode, all settings are wrong for both cameras. (2nd pic) On 1st pic we can see right setting.. &My flash light, camera flash as well is not working, when I check in the cit mode flash light is working. Did factory reset, downgrade miui and custom ROM also tried. Still problem..Can i use persist.img to fix?
