Re: A1674 Wi Fi & Cellular. Son’s iPad, admitted to having “jailbroken it” Tried to upgrade to IOS 11. Restore fails about 2/3 of the way. Error56 Tried different PC’s, cables, etc. Apple tech says…probably Logic Board. Where can I find Logic Board, have experience repairing iPads, iPhones etc. Thanks in advance!!
It will be very difficult to find a replacement logic board for the iPad Pro and even if you do, it will be as expensive as getting a entire iPad Pro replacement unit. You could try to find a micro-soldering repair shop and perhaps they can fix it for you, which would be more economical.
