Choose your “type of brick” :
Type 1
Your phone is completely dead.
Type 2
Your phone boots up but hangs on the Samsung logo and boots into download mode or shows a corrupted white screen and boots into download mode.
Type 3
Your phone boots up but hangs on the Samsung logo or shows a corrupted white screen and boots into download mode, but it has an incompatible bootloader version with the tool (follow type 2, you’ll see when it’s incompatible).
