I have an old iPhone 6, I have recently tried restoring it to factory settings but no luck. I’ve tried through the phone and connecting it to iTunes.. nothing worked. Currently it’s stuck in recovery mode and I can seem to get it out of it. I’ve tried everything I know. It was thrown at a wall once so maybe a component inside is damaged? Error 56 problem.
Have you tried using “3uTools?” I had the same problem. 1.Download 3uTools 2.Install it(Obviously) 3.After Installation connect your IPhone in Recovery mode 4. In 3uTools select the option called “Flash & JB” 5.Select the option called “Easy Flash” 6. And after that you will see a list of available IOS versions for your IPhone. 7. Untick the option called “Retain User’s Data While Flashing” Beside Flash 8.Just tick the Circle of the version of IOS you prefer and click “Flash” If not, try visiting your local apple store
