Flashed "additional partitions" downloaded from microg site
Installed lineage recovery from their site
Factory reseted phone from recovery
Downloaded lineageos .zip from microg site
Run phyton script to verify .zip
Adb sideloaded .zip
Phone's terminal again displayed something like "signature verification failed", "status 1" and "rebooting may fail, continue?"
I rebooted and same situation as previous time occurred: boot animation, sound and black screen. Can hear "usb connected to pc" and "sound and turn off screen" sound.
Later that day I have panic installed xiaomi.eu rom and it thankfully booted. Today I have followed every step again. (https://wiki.lineageos.org/devices/alioth/install/variant1)
It seems like python script is faulty
Should I give up now and reinstall stock?
