what happened here is: I did a master hard reset on my phone samsung giorgio armani B7620.

Now I can use internet through wifi on the phone. all the apps and other stuff works except there is no network signal.

I bought this phone unlocked. It's a GSM quadband phone.

is it because the phone is missing the radio firmware after I Hard reset it? if it is can you please link me an appropriate radio firmware.

Can someone help please? I hope its not the antena of the phone that burned out. I barely bought this phone two months ago though.

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.

Please help? , someone help me with this problem.
I'll donate who ever can fix this problem for me.

Same issue here whit my B7610. It's a know problem around the world. I'm afraid that your phone have a serious hardware problem and the only solution is to go to a lab.
My lab report "replaceing soldering elements", i think that all my radio module have been replaced.
So sorry for that. Hope that your warranty is still on.

The phone will automatically go into boot loader mode when you switch the phone off, connect it to your pc and octans detects the phone
