[Please help] Samsung S6 security error message
(13-12-2017, 08:12 PM)Olanie I have a Samsung S6 that displays "Security Error: This phone has been flashed with an unauthorized software and is locked ..... "
No network service, it keeps searching.
It was unlocked with Tmobile Device Unlock app.
The imei is intact.
I have flashed with various stock roms with Odin, and also with Kies.
Any other idea on how to resolve this?
