can't downgrade 3.0 to any previous firmware...
Hi folks, i've tried everything to try and fix this and need a fresh pair of eyes.
My problem is that when I try to restore to anything below 3.0, i'm getting the dreaded 16xx errors in DFU mode. I have not found a solution to this as yet and was wondering if someone could help me out.
The phone unfortunately won't do anything in anything less than iTunes 8.2.
If i use normal restore mode and try for example 1.1.4 or 2.1 or 2.2.1 firmware I get error 20 etc ... using the same firmware in DFU i get 1600, 1601 or 1604 error.
At the moment the phone is sitting on v3.0 F/W, a fresh clean apple version. The modem firmware is sitting at 04.05.04_G.
Is there ANY way to do this.
Thanks for your help guys.
ps I should also say, that I have tried this on vista, xp and windows 7 with the same results :-(
