'No Service' after Unlocking a 3GS on 4.1 With Ultrasn0w
The phone was bought from USA (AT&T locked) and I jailbroke it with Limera1n and unlocked with Ultrasn0w. Everything went very smoothly up till the no'service. I've tryed toggling Airplane mode, rebooting, different Sim cards and reinstalling Ultrasn0w. I had the AT&T sim card in in up untill after I installed Ultrasn0w but I can't really activate it because I'm in UK?
Any help is much appreciated.

How did you activate the phone?
-
05-31-2011, 11:57 AM #7I'm not 100% sure what 'activating' en tales but I managed to get to the homescreen from the emergency call screen by inserting the AT&T sim card and then Itunes was satisfied and then asked me if I'd like to set up iPhone as a new phone. Originally Posted by Simon

Ok, then you activated properly (got past emergency call screen). Not sure why you cant get signal, maybe try a restore and set it up as new.

Shouldnt really make a difference.

05-31-2011, 01:57 PM #11Could it be a hardware issue? The rear assembly and screen was replaced but the battery and motherboard is the same original Originally Posted by Simon

It's possible the radio could be busted.

Something similar happened to me. Where everything worked fine then after a while i would get No Service or it would just constantly search. After that it would just reboot and reboot.
I fixed it by taking my sim card out and restoring to a custom firmware i created using Sn0wBreeze or whatever it's called to create custom firmwares on Windows. After i installed Ultrasn0w it worked fine it hasn't dropped the service yet. It seemed like what screwed up the unlocking process was having my sim card in it.
