Before flashing my 13, did you have my stock global?
And why did you also delete the app data permissions first?
If I load the xiaomi.eu rom from 12.5.7 global with windows_fastboot_update_rom.bat do I lose all application data? And above all, does it work? Or do I have to reconnect on whatsapp, telegram and the other apps?
One last thing, boot.img do you modify it before or after loading the rom? Do you upload it directly patched?
Thank you for the help!!
I came from MIUI 12.5 xiaomi.eu ROM (android 11)
The way how permissions work are changed in Android 12 and this MIUI permissions app needed to be reset. It gave a lot of errors and sometimes crashed the phone.
Normally it should keep the data, it did for me, but do make a backup! If you don't have root you can use the MI PC suit (

I had to run
windows_fastboot_update_rom.bat twice for it to work.
If you don't need root, you do not need to this step. But if you want root:
1. Copy the
boot.img from the
new ROM folder to your phone ( Xiaomi.eu_****-fasboot/images/boot.img ).
2. Open up Magisk -> Install -> "Choose and patch a file"
3. Copy the patched boot.img back to Xiaomi.eu_****-fasboot/images/ folder > remove the original boot.img > rename the patched boot.img to
boot.img
4. Put your phone in fastboot
5. Run the
windows_fastboot_update_rom.bat (if the first time fails, run it a second time)
Good luck
