Hello everyone,

I used the easy installer to install e OS on my Samsung S8, but I always get the error message (see picture). what can I do? I need help

checkout this thread, same device / issue - Bootloop issue (SM-G950F)

it had the same errors your screen shows. I use to write them out to make it easier finding existing threads
