Bad LCD, Reset to Factory I have a galaxy sII (i9200m) updated to the latest firmware and would like to do a factory reset. I have no idea how as the LCD is completely shot (solid black). 

Hope you can help.

Thank you
Since you have no access to the UI, the option would be using the adb shell.

Note: the adb shell will Only work if USB debugging was Previously enabled!

Connect your device with the USB cable. (install drivers if needed)
Use a terminal (or cmd if in windows) Change to your adb location directory. Run the following to do a recovery wipe:

adb shell
&gt; recovery --wipe_data
