so a short update about the situation of 12.2.7 for Mi10
Gpay working no issues anymore no idea why but it is what it is
what i've done as i messed up anyway:
download TWRP TWRP3.4.2.b1206 from the forum
Downloaded 12.2.2 and 12.2.7 from forum as i had notification issues whicha re gone as well now
boot into fastboot
fastboot/adb shell comand: fastboot devices (should be listed if not enter adb devices to start demon)
fastboot boot twrp.img (or whatever you named it. Need to be in same folder as adb)
give it time it should be loaded fast in command but it actualy take like 30sec to boot in twrp
Ignore the steps i did to avoid loosing data. marked with a -
-Delete data etc so it was completly empty
-adb devices
-adb push xiaomi.eu_multi_MI10_V12.2.2.0.RJBCNXM_v12-11 /sdcard
-wait a very long time do NOTHING it take time to transfer the date
-when done install zip within TWRP
-clear dalvik etc again. also data
-boot system
after booted up i only installed backup from google. NOT XIAOMI!!! very important for xiaomi backup: do NOT, i repeat do NOT restore settings from cloud. only missing apps AFTER google is finishd. Why? because it messed up my energy settings previouse thats why i complete reinstalled everything. had no notifications and i was able to reproduce the issue after the xiaomi backup restore with settings incl. Do as you wish but keep in mind it messed with my energy settings and had no chance to keep apps running in background with a lock and ignore energy setting enabled.
So after system is working or you want to update do the following and no data will be missing as i tryed and others as well:
download the newest firmware to the phone from updater
Disable fingerprint and lockscreen. (i will test it a other time if it works or not to decrypt with a pin. some say it can not decrypt anymore but it worked all versions till now for me)
turn off phone and boot into fastboot
on pc: fastboot devices (if not showing do adb devices and start demon again)
fastboot boot twrp.img (as you named your twrp used previouse)
once booted install zip from internal storage
after flashing just reboot to system do nothing else
patience for the boot as all updates take their time to boot first time afterwards. like 5 minutes or maximum 10 minutes i say
your done.
If a pro want to add something or want to correct me please do it and i will adjust this post accordingly
Edit:
important note: if you fail to fastboot boot twrp bc of a error message reenter fastboot on phone by pressing volume down and power at the same time and try to boot twrp again. if still not working repeat it
Edit 2: gpay not worked at first, but as i use revolut i added the card from within revolut to gpay and since then gpay worked also for me other card. Safetynet still fails but that crap can go somewhere else in my opinion
Edit 3: you can use a OTG USB stick to put the firmware on that instead of use the command "push". thank you @
