Maybe I should ask
How can I downgrade/change my firmware to 3.0 with cydia. I have tried several time, with itune and redsn0w 0.8v using the 3.0 firmware ( iPhone1,2_3.0_7A341_Restore.ipsw).

Note :-
Using iTune update restore the 3.0 firmware it do giving me the error msg half way the update
Using the redsn0w 0.8v the cydia installation fail.(Complete the uploading process and not the installation of the cydia, did not show the pineapple graphic. after the harddisk graphic then go restart and give me the insert sim to activate screen)
Both process also giving me the insert valid sim card to activate iPhone.

Hi All,
This is on the 3g iphone. I am now stuck at the insert Sim card to activate Iphone error. Even I had try to restore the firmware and seem that the cydia cannot be install into the device. It happen after I update the firmware from 3.0 to 3.2.1. (Window mode using the iPhone1,2_3.1.2_7D11_Restore.ipsw). I had tried:-

a) Restore to firmware 3.0 with iTune(v8 and v9). Fail to do, half way the restore process, prompt me an error.
b) Restore to firmware 3.0 with Redsn0W v0.8, complate but did not install cydia(not seeing the pineapple screen). reboot and get back to the same error(insert Sim to activate)
c) jailbreak with the blackra1n and complete all the process(no error) but still go back to insert valid sim card to activate Iphone screen.



What can I do next and what went wrong on the process? Please help..............


thanks

It is not an unlock phone, previouly unlock with ultrasn0w. What happened? How can restore it?
I am not update with the Apple firmware but I am using this to (iPhone1,2_3.1.2_7D11_Restore.ipsw) do the update.
What can I do now? Please help............


Any way for me to jailbreak it without a AT&T sim card? Should I update the firmware to Apple original firmware?
It is now always on the insert sim car to activate iphone screen.



thanks

I followed the step listed there. DL the custome firmware (iPhone1,2_3.1.2_7D11_Restore.ipsw) and do the restore (Shift+ Restore) thru iTune and get stuck at here. Does this update the baseband? What can I do know? Waiting for the jailbreak on he latest baseband? I am unable to confirm the baseband. Anyway to confirm the baseband if the phone always in insert sim card error?
I am ok if no phone fuction and only can be use like ipod for time being, but now it is totaly cannot use.


thanks
