Unlock Samsung Phone giorgio armani b7620
I've been struggling with this no network signal for a week now.
I have AT&T. I was thinking maybe something is wrong with the antena of the phone. so I put my friend's T-mobile sim into my phone. It had signal and worked fine. Then I put my AT& T sim into his unlocked Nokia N97. It worked fine. so the antena is still good. and there is nothing wrong with the sim.
I remember I left my sim in the phone when I did the hard reset.
What happened here is: I had a password lock on the phone to prevent others to use it. Last wednesday I entered the same password as I always did, but the phone did not open up. Therefore I had to do a hard Reset.
so I think most likely, the phone set a sim lock by itself on AT&T simcards while I was doing the hard reset on it. Now when I put my mom's simcard (also AT&T) in the phone, and it doesn't show any signal. No signal, no call, no receiption.
I am trying to flash it with a different radio version. but I don't know how to put the phone (Samsung Giorgio Armani B7620) into the Boot Loader mode.
, someone help me with this problem.
I'll donate who ever can fix this problem for me.
