Phone crashed, now doesn't boot and stuck at os install screen
Hello. So I'm trying to figure out what happened to my sisters phone.
It crashed and it would get into a boot loop. Every so often it would boot into the lock screen but then instantly crash.
So I tried to get into recovery mode and do a factory reset since she had all her photos saved anyway.
And now it's stuck on this screen:
And I literally can't do anything. It doesn't respond to any button presses and if i hold power button it won't shut down.
What could be wrong with it? Should I take it to a professional to fix? How much would it cost???
