I accidentally updated my 1.1.2 phone and as per guide have tried to Restore to 1.1.1 to fix the problem. I just keep getting the message "Can't Restore - Unknown Error (1)" I tried to reboot the phone with iBrickr and just get a green screen (never seen that before!!). Then just get scrolling text and code on black background. Not sure what to do from here. HELP!!
but pay attention! If u already in recovery mode, u'll need to "boot from recovery" through any app. I did using 1.1.2-Jailbreak by Touchfree application.
Same problem happened to me. What i did was put it in DFU recovery mode and downgrade to 1.0.2 firmware. Then i just restored it to 1.1.3 and it works fine now
