My Samsung Galaxy S6 (SM-G920T) on Marshmallow 6.0.1 with Superuser Access doesn't turn on, and it's just a black screen. This happened after I tried to reboot after installing Xposed Framework. I've tried everything. Even dismounting the battery, but nothing works. I heard that the problem can be resolved by installing a fixed OS. Is this true? And if it is, where can I download it? I know how to install custom OS, I just need to know where I can find it.
