how to format without * # 7370 # on the phone is turned off.
Tried everything, different versions.
Or so it is not formatted?!
I tried version 701, C7, N8
My understanding is that OP has already tried this, although you need to release power button only after first vibration keeping other three depressed until Nokia "Shaking hands" logo appears.
There have been some unconfirmed reports that for 603 key selection is Green (Call), Red ( Reject) and Camera whilst powering on.
