I have an iPad 4 that I haven't used for so long that I forgot the PIN. After too many tries now my iPad is disabled and now it requires iTunes to fix.
(Error Showing: iPad is Disabled Connect to iTunes)
I tried restoring and updating via iTunes but it keeps giving Error 3600.
Device: iPad 4
IPSW (Which was downloaded by iTunes): iPad_32bit_10.3.3_14G60_Restore.ipsw
iTunes: 12.9 latest as of today
OS: Windows 10
Tried changing cables, restarting, restoring by putting in DFU mode and everything else that is mentioned by others on the internet.
