Are there any improvements on bg apps? I've had them restarting over and over again starting 12.5. The update showed up in my notifs but was gone when I went to the updater.
i didn't test it, as soon as i noticed that 12.5.4 isn't smooth as 12.0.9, i immidiately switch back to 12.0.9
because .eu 12.0.9 safetynet isn't passed by default, so you must fix with magisk root and use universal satefynet module from kdrag0n
I had your problem too! My first TWRP was "3.4.0-0 By mahajant99" and got the Unable to Decrypt message.
Then I tried to decrypt phone using this https://forum.xda-developers.com/t/...ck-twrp-factory-image-stock-recovery.3358711/. Installed the app in Windows 10, executed the "Erase All Data / Decrypt Internal Storage". But there was an error there too, so I think it didn't decrypt anything...
After I changed TWRP to "twrp-3.4.0-15-surya-mauronofrio" and rebooted to System and MIUI was on the screen!
After the boot I got a message saying my phone was locked and to unlock it I had to enter my Xiaomi Password and that I did and the phone got unlocked.
I think this was all I did...
Now I have the EU ROM and Root.
By the way, in the "TOOL ALL IN ONE" there is no option for X3, so I selected Poco F1 I guess... I know it was another Pocophone...
Just remembered I read in another site about flashing another .img and a ZIP file, and I asked about it here. Just went to history and here it is: https://unofficialtwrp.com/xiaomi-poco-x3-root-twrp/
I don't know if it will help you, but in there states that, after flashing TWRP, DON'T BOOT TO SYSTEM! First flash "no_verity_opt_Encrypt.zip". Again I ended up not doing what it says there (flash "Vmbeta.img" and flash "no_verity_opt_Encrypt.zip"), but it's another option for you, in case your phone is still stuck on TWRP...
Good Luck !!!!!!!!!!!
Flash the global fastboot rom using Mi flash .... make sure you haven't relocked the bootloader by unchecking the necessary box
Reboot into system
Boot into fastboot
Flash Orangefox recovery image using adb
Reboot into recovery before you reboot into system or you will lose OF
Boot into OF then flash Xiaomi.eu
Format data .....
Reboot into recovery
Reboot to system
These are the steps I used.
