Mobile screen blankl?
the code you typed in is used to restore factory settings. turn the unit off, give it a few minutes then turn it back on. let the software resume processing the reset feature, the screen will just be blank for a few minutes. wait about 10 mins and if the lcd is still blank then take it to the nearest service center. taking the battery out after you keyed in *#7370# probably damaged the software.
