Anyone who could help me out with this situation would have my sincere gratitude.
Here's the situation.
Me and my buddy both own W830i's and they appear to be from the same lot (1st 11 digits of IMEI match).
He took his w830i to get unlocked from someone that really didn't seem to know what they were doing. Now his W830i thinks its a W850i, and this guy who did the work, can't change it back and wont return his calls.
His phone now, cannot make phone calls anymore, and the camera feature reports that another application is using it. He's freaking out and wont stop bugging me, to try and fix it, as I am more computer savvy than him.
Is there a way I can fix this situation? (Such as transfer a copy of my firmware to his phone?)
Any suggestions would be helpful.
