Iphone 2GS 3.1.3 after unlock no signal

[tethryus]

iPhone 2GS 3.1.3 Jailbroken it with Spirit, then I tried to unlock it with ultrasn0w (from cydia). As soon as I`ve done it, when the device rebooted, I couldn`t get any signal on the original sim card. Has anyone have the same problem?

Was it working before ?
Are you sure isn't barred?

 

[afrimian]

is it 3gs ot 2g ?!
you wrote 2GS

 

[tethryus]

it`s 2g, it`s not barred, I rewrote the firmware on it, and it works on the original sim without any problem. the phone is 2g, version 3.1.3 modem firmware 4.0.5.0_g. Only when I unlock it with ultrasn0w, i can`t get any networks to work on it.

You can't unlock 2G with ultrasn0w. Use bootneuter instead.

3. download redsnow 0.9.4
4. in redsnow open 3.1.2 firmware for 2g and press next.
