[itsXactlY]

Hey, so far its 'freezing' after 10 to 100 trys, stuck on Bootloaderscreen, nothing else happens.

P20 Pro (CLT-L29)
Android 10 (will try downgrading to 9.x)

Any idea(s)?

Hi,
not sure if downgrading Android will be a good idea. The opposite would be better.
I've the same smartphone with the latest updates and its working quite well.
