Hey all!!!

The iPhone won't update. It won't progress past the point shown in iTunes/the phone in the pictures attached.

I have tried updating with the screen off, with a different original screen, a new battery inserted.

It did at one point restore, but then it turned off and started boot looping with vertical lines showing up on the screen.

Any help appreciated!

What happened between the phone working well and the failed update? Is the phone still boot-looping?

Try these things (if you haven't already) to see if anything helps:

  • Try a hard reset (Home & Power button for 10 secs)
  • Use a genuine Apple Lightning connector
  • Use a genuine Apple charging brick and let it charge overnight
  • Try to connect it to different computers (mac/pc if possible) with an updated iTunes
  • Put the phone in recovery mode (search DFU Mode). Careful, this can reset your data
  • Use 3uTools for putting it in and out of Recovery Mode
  • Use 3uTools to flash the firmware (you can't downgrade)
  • Check the condition of all the flexes (with magnification)
  • Disconnect the Front Camera Ribbon from the logic board and reboot your phone
  • Disconnect the screen assembly completely and see if iTunes will recognize the phone.

Otherwise, you may have a logic board issue. If you are uncomfortable doing these steps, consider finding a repair shop to do the troubleshooting. A shop that also does micro-soldering can go deeper if the problem is not modular in nature.
