iphone 3gs just showing searching for signal

[tamgunner]

hi all i have a 3gs 16bg i accidently updated it to 6.1.3 with baseband 6.15 managed to jailbreak it with redsnow and installed ultrasnow but all im getting now is searching i have a sim card in and i know its working the wifi is working ok to ive opened it back up and checked all the connections which are on.

only two things i can think of it can be is a software issue or a faulty anntena.

is it possible to downgrade to 6.1.2 without the shsh blobs

mate. there is no downgrade possible. Did you install ultrasnow fix? all ios 6.x.x needd ultrasnow fix installed and after that original ultrasnow.(only your baseband)

[tamgunner]

uninstall all ultrasnoww..completley, after which install ultrasnow fix, and ultrasnow original.

also amke sure you iphone was activated properly with a valid SIM, not HAcktivated or via jailbreak

how can i check it was activated properly with a valid sim? i bought the phone off ebay installed a new battery n screen connected it to itunes to see if it was working and it came up asking to update i didnt think anything of it so went ahead and updated it then i tried to jailbreak it only found out that i shouldnt of when i had no service. would it be worth buying a replacement anntena just in case its thats faulty?

[ominimicu]

no i really dont think it s the antenna.but more a SIM compatiblility problem. When you updated did it do the activation process?

[tamgunner]

not sure cause when i updated it the screen wasnt connected just updated via itunes and that was it didnt have a sim card in or anything before i jailbroke it itunes did say it couldnt activate it if that helps
