    Did you cook a custom 5.0.1 firmware with Redns0w or snowbreeze? your phone has Ipad baseband on it and you can't restore it to Apple office firmware.

    Apple stops signing 5.0 already, you can't restore to OS5 any longer, you can only restore to the latest firmware Apple is signing now which is 5.0.1. So, you must use snowbreeze 3GS-5.0.1 and not OS5.

    Yes, you can downgrade it to 4.1 without any problem. Make sure you put the phone in DFU mode first.

    As per Dev blog, Ultrasn0w has not been updated to be compatible with 5.0.1. This might be a problem that it is not working.

    Since Apple stops signing OS5, you can't go back down to OS5. you can only downgrade it to 4.1 and then jailbreak and unlock it. The reason you can downgrade to 4.1 is that for some reason, Apple still sign that firmware and you can downgrade it to that firmware without SHSH blobs save.

    Yes, you can. Also, check to see if you have old bootrom or new bootrom 3GS, if you have old bootrom 3GS, then you will have untethered jailbreak on 5.0.1 when you decide to go back to this firmware.

    You can use official 4.1 fw to restore your phone to it. At the end of the process, Itunes will give you a 1015 error. Open tiny umbrella, click on your phone at the upper left hand corner, then look at the upper right hand side, click on the box "exit recovery". Your phone will boot up to emergency screen.

    2 things you can do;

    1. Activate with official sim, then jaibreak it with Redsn0w or limera1n, then unlock it with Ultrasn0w.

    2. If you don't have official sim on hand, then hactivate/jailbreak it with redsn0w, then install Ultrasn0w from Cydia to unlock it.

    Listen to what CRX is telling you, he knows his stuff well
    And next time dont be in a rush to upgrade when the unlock is not even compatible with the firmware version you're upgrading to and cant even use the device as a phone.
    You can even restore to a custom 4.1 IPSW created with snowbreeze or pwnage.

    Crystal, u seem like the guy to ask. I have the same problem as this and have followed the steps but i was on official 5.0.1 with no signal and have used the official 4.1 to downgrade, i didn't get the 1015 error code and i've tried to jailbreak and deactivate with redsn0w but its not deactivating, i'm just getting the plug into itunes screen, any ideas??
