I am trying to Downgrade Baseband from 02.30.03 to 02.28.00 for my iPhone 3G. My phone was accidentally restored with 02.30.03 and now I cannot use my phone. So now Its not jailbroken or unlocked anymore.
Now, I am using Quickpwn to jailbreak it but cannot because I keep getting error 2001 and one time I got error 1621. I read every1 elses answers to this same problem but it didnt help me. Now Im stuck with no cell phone to use, PLEASE HELP ME!!!
Thank you very much
