Ella Garcia Updated on Apr 26, 2022 8:15 PM

iPhone 8 (Plus) isn't particularly prone to a boot loop, but when this happens, there's a good chance that something goes wrong during the boot process, leaving the operating system unreachable. You should be facing anything from software errors to a serious hardware problem.

What Is a Boot Loop in iPhone 8 (Plus)?

A bootloop is an error that makes your iPhone restart endlessly and never pass the Apple logo screen. It often dies until the battery is completely drained. The cycle keeps repeating, showing the Apple logo and then the black screen, but it's unable to boot to the Home screen.

What Causes an iPhone 8 (Plus) Boot Loop?

It's never fun having to deal with an iPhone 8 (Plus) that's stuck on boot loop with Apple logo over and over. But how the looping begins? It can be diagnosed as one of three things:

  • An iOS update, or an iOS restore or reset goes wrong
  • Conflicts with iOS Jailbreak, and your phone is stuck in reboot loop issue.
  • Hardware damages (bad battery connector, broken charging port, smashed screen, etc.)

How to Fix iPhone 8 Endless Boot Loop?

With the clues about why iPhone 8 (Plus) went to rebooting loop, check out our guide below and get the device booted up correctly. The troubleshooting process could take from minutes to hours.
