4S searching technical question Hi
Very technical question
One customer sold me his iphone 4s with broken screen
I change new LCD ,but soon phone switch on asking for password (no access to customer )
I can flash it but if I flash phone while it searching for signals I might have -1 error which happened to me before (-1 error is IMEI crape)
Any idea how I get out of this issue
Plz expert advise |
