Click to expand...
Click to collapse
Download odin and stock rom files to flash with odin (make sure you use correct files or a brick will happen)
Shutdown the phone (if needed hold power button 10+ seconds until bootloop stops).
Plug phone into computer and turn the phone on and as the phone vibrates release the power button, then hold down the volume down button and home key. then follow onscreen instructions.
for flashing instructions please search the mobile section of these forums.
I followed all the intrusions given and the only thing that as changed is the cwm. its still stuck on the Samsung screen and not moving.

S6 (G920T) Bricked and Never Rooted

I was taking a picture the other day and then my phone rebooted to the Samsung logo, and stuck there for like 2 hours until it ran out of battery.
After that I tried to boot into recovery mode but it also got stuck at the Samsung logo. I could get into download mode though. So I tried and successfully flashed the firmware through both Odin and SmartSwitch but when I boot up the phone it gets stuck at the Samsung logo again...
Has anyone else encountered this issue? Can anyone possibly help me
If you are trying to get in the recovery you shouldn't have reached the Samsung logo. When completely off, hold the power+home+volumeup until you see the recovery. Don't just press them and expect to get into recovery. You are gonna see the splash boot animation Samsung Galaxy S6 G920T hold the buttons and after that you will see the recovery.
