[armen71]

Hello guys, i successfuly created a custom restore file on a mac using pwnag tool, and when i tried restoring the firmware to the fone using the usual method, putting the phone in DFU mode, it kept giving me error 1600 and 1602, i tried several times and it didn't work, we even tried it on the Mac mahine that we created the restore file on, still giving me the same error. Can anyone please advise what to do ? thank you
