IPhone Boot loop stuck

bootiphoneitunesrecovery

The phone has never been jailbroken. Never got wet, anything.
But after one night it reboot, and got stuck. The battery overheat and even after a few attempts to solve the issue through iTunes, Recovery and DFU mode, it continues stuck at the same part of the boot.
I really don't know what to do anymore.
It is an iPhone 7 Plus 256, 2 months without warranty! Thats the worst!!
I'm running iTunes 12.7.2.58 on a MacBook Pro

Many things can cause a boot-looping device.

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)

If you are comfortable opening your device (now that it's out of warranty) then consider the following:

  • 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 either doing an OOW replacement at Apple or finding a reputable, independent repair shop to do the troubleshooting. A shop that also does micro-soldering can go deeper if the problem is not modular in nature.
