Sir mArvin at sa ibang nakakaalam dyan:
Iphone 3GS 16GB
MC136LL/A - iPhone3GS
AT&T Factory Unlocked
IMEI: 012028001829610
Serial: 3249044118958
Baseband: 5.13.04
Firmware: iOS 4.1
Status: No Service (Searching...)
Na-try ko na rin po update to:
Firmware: iOS 6.1.3
Baseband: 05.16.08-6.4_M3S2
Same problem pa rin po
No Signal (Searching...)
This is what i've done: (Following tons of web and youtube tutorials")
1.) Restore to firmware 4.1
2.) Jailbrake with redsn0w and install Ipad baseband 6.15.0
3.) Downgrade ipad baseband to make it 5.13.04
4.) Everything is fine except that "No Service"
Then i tried:
Update to iOS 6.1.3
Baseband: 05.16.08-6.4_M3S2
Attempted to jailbrake but no success coz mag-sta-stuck on "Waiting for reboot" si redsn0w)
Same problem... No Service (Searching...)
If disable ko po yong Automatic sa carrier setting, Ma-dedetect po lahat ng available network. But if i select the carrier with my corresponing sim e.g. Smart, magpa-prompt ==> "Network Lost" "You are trying to connect to network that No longer exist..."
(May nabanggit po kayong Iphone 3gs new bootrom need to have the original sim for activation. Kahit AT&T factory unlocked na po, need ko pa rin ba?)
Please help po?
Hardware related problem na po ba to?
Please help po guys
... tnx
