I keep getting error 21 while restoring my ipod touch 5g 32gb to ios 6.1.3 from 7.0 b2 while in DFU mode. i have a faulty cord and i was wondering if that had to do with it, if it is any help, i also got 1611 while trying recovery mode. i need to know if the cord is the problem before i go spend an outragous 20$ on a new cord. thank you if anybody can help. any questions, look at my previous thread.
