Success after getting error 1601
Using winpwn to upgrade from 1.1.4 (iLiberty) with itunes 7.7 on XP - Folllowed iClarified directions and got error 1601.
After several tries using various suggestions on this and other sites, I was about to downgrade itunes to 7.5.
Investigated a little further first (REALLY didn't want to downgrade) and found comments on making SURE that you go into DFU, not recovery mode.
Apparently it requires a little more finesse to get it right with iTunes 7.7. Once in DFU the Custom ipsw loaded with no problem.
Took about 10 minutes, then some waiting while the bootloader was neutered. After that, I restored from the iTunes backup to recover contacts, notes etc. and I was good to go. Checking out the AppStore selections now.
Thanks to all who took the time to comment and contribute!
