Few things are more frustrating than when your phone refuses to start properly. You press the power button, the Apple logo or Android animation appears, then it shuts down and restarts over and over again. This endless cycle is called a boot loop.

At Reparation Tech, we regularly handle boot loop cases across iPhone repair, Android repair, and tablet repair services. This blog will guide you through:

What Is a Boot Loop?

A boot loop occurs when a phone gets stuck restarting itself repeatedly. The device never fully loads the operating system. Instead, it cycles between the logo/startup screen and shutdown.

Symptoms include:

iPhone stuck on the Apple logo then restarting
Android stuck on boot animation and restarting
Endless reboots without reaching the home screen

This can happen suddenly after an update, app installation, or hardware problem.

Causes of Boot Loops

For iPhone:

Software Update Failure – Interrupted iOS update causes corrupted system files.
Jailbreak/Unauthorized Modifications – Instability from unsupported tweaks.
Corrupted Apps or Data – Malfunctioning apps crash the boot sequence.
Hardware Issues – Failing battery, loose connectors, or damaged logic board.

For Android:

Custom ROMs/Rooting Errors – Flashing unsupported software.
App Conflicts – Faulty apps installed outside Google Play.
Corrupted Cache or Data – System cache corruption leads to restart cycles.
Battery or Motherboard Faults – Power instability triggers endless reboots.

DIY Fixes for Boot Loops

Step 1: Force Restart

iPhone: Quickly press Volume Up → Volume Down → Hold Power until Apple logo appears.
Android: Hold Power + Volume Down for 10–15 seconds.

Step 2: Charge with Official Cable

A weak or faulty battery can prevent full boot. Always use certified cables.

Step 3: Safe Mode (Android)

Hold Power → Tap and hold “Power Off” → Safe Mode.
If boot loop stops, an app is causing the issue.

Step 4: Recovery Mode

iPhone: Connect to iTunes/Finder → Enter Recovery Mode → Choose Update.
Android: Power + Volume Up → Wipe Cache Partition.

Step 5: DFU/Factory Reset

iPhone DFU: Connect to computer → Enter DFU → Restore iOS.
Android Reset: In Recovery Mode, select “Factory Reset.”

⚠️ Warning: Factory reset erases all data.
