Which iOS are you trying to jailbreak.

The firmware of my 3GS is 05.16.08
And using redsnow, i install ipad baseband 06.15.00

i read some forum, to be able to restore the 3GS i should remove or replace ipad baseband.

but i didnt know how to remove or replace and what i should replace...

Thanks

Which bootrom does your 3GS have. If you try flashing the iPad baseband on the new bootrom outside of iOS 4.1, you can potentially brick your device. And if you want to downgrade the iPad baseband, run RedSn0w, select the iOS 6.0 IPSW, then click Jailbreak. DFU the device. In the menu with the tickboxes, only tick the option to "Downgrade the iPad Baseband". Untick everything else and let RedSn0w do its thing.
