I could only use Vol Up + Power button to turn it off. It still freezes on the next reboot. It doesn't even vibrate at the start screen, so I cannot enter the XZDualRecovery mode. Please help.
You should follow the instructions in the thread.
You have to flash the srtipped FTF before rebooting. and there is no need for a full wip, you lose all your settings then.
To fix it, just flash a stock FTF and start again (You could try flashing the stripped FTF)
