Hi guys having problem with my 8520 curve not booting up.it turn off but not on..I put a higher os but the same thing happens..
Have you wiped your device before loading the latest OS ?
I don't think I wiped it before I loaded it
So I suggest wiping your device & loading the latest OS.
Follow our guide : All In One Guide - How To Upgrade Your Device - with Pictures & Videos
Also you can find in our Downloads Center the latest Official & Leaked OS for your device.
