Tech Tips

If your Samsung or Android phone is broken and caught in a reboot loop, there’s a few solutions that can help restore your device functionality without too much time or effort. In this article, you’ll find a few of our favorite fixes for this frustrating device issue. Our solutions are broken down into a few simple steps that you can follow on your own from the comfort of home. But in order to apply a solution, first you have to fully understand what the problem is. Let’s take a closer look at why your Samsung keeps restarting and how to fix it.

What Causes the Restart Loop?

The reason the restart loop manifests in Samsung and Android devices is typically related to a communication error preventing the completion of the initial launch sequence. This error can often be traced back to corrupted files or applications, viruses like malware and spyware, or even broken system files. Ahead, we’ll look at some common fixes to address these errors and see if we can resolve the problem. If your Samsung keeps restarting, read on! You might be able to get your phone working again before you even reach the end.

Removing the Battery

It’s possible that some electrical charges could be causing a reboot loop, for this reason it’s a good idea to try a soft reset before doing anything else. All you need to do is remove the battery if you have one that can be removed, or simply turn the device off. You’ll want to wait some time before replacing the battery or turning the device on. The idea is that we want any possible residual charge in the device’s circuitry to dissipate before attempting another reboot sequence. If this doesn’t work and you find your Samsung is still caught in a loop, don’t worry, there are still plenty of options ahead.

Rebooting in Safe Mode

The first thing we should try to do if our Samsung or Android device is caught in a boot loop is to try to access safe mode. Safe mode limits the device to only the applications and system data that are factory default. If your device works in safe mode, it tells us the restart loop is likely related to a corrupt application. From safe mode, you’re able to reboot the device, allowing the loop to break and potentially repair itself. To enter safe mode, first turn off your phone (this may require removing the battery in some cases). Once off, press and hold the power button as the Samsung logo appears. When the logo shows up, hold the volume up key; the lock screen display menu should show up. From here, select ‘Safe Mode’ and then ‘Reboot.’

If you’re unable to enter recovery mode or it doesn’t solve the problem, don’t lose hope. There are still a few options we can try out. Next, we’ll look into two more device modes that allow us a bit more control.

Using Recovery and Download Modes

These lesser known debugging modes are used to restore some of the more complicated software issues encountered in a Samsung device. The ‘Download’ mode can update firmware and download software, while the ‘Recovery’ mode is used to restore the device to its factory settings– which also wipes all pre-existing data. What both of these modes have in common (and why they matter to us) is that they are both alternative booting sequences, and have the potential to break the reboot loop our Samsung smartphone is stuck on. 

Let’s try ‘Download Mode’ first. To access it, you’ll need to press a few keys in your device at specific times. Simply follow along the following instructions:

 

  • Turn off your Samsung device. You may need to remove the battery to do so.
  • Hold the power button, the volume down button, and the home button simultaneously until a warning screen is visible. 
  • You should now be in ‘Download Mode,’ and the reboot loop should be broken.
  • Turn off your phone again by pressing the volume down key to exit the mode.
  • Check if the problem is fixed. If not, try ‘Recovery Mode’ next.

 

Like download dode, recovery mode also requires a sequence of button holds. In this step, we’ll try to reboot the phone and clear the cache partitions. Clearing the cache data can solve a variety of issues, and even improve overall device performance. Follow these instructions to enter recovery mode.

 

  • Your phone should be off for this as well, so go ahead and shut it down.
  • Hold the power, volume up, and home buttons down simultaneously (like before).
  • You should now be in Recovery Mode. 
  • Navigate to ‘Clear the Cache Partitions.’ 
  • Return to the main recovery mode menu, and select the ‘Reboot’ option.

 

Hopefully your problem is resolved, but if not, there are a few more options you can try before taking it to an expert for further repairs. 

 

Resetting Factory Settings

The last option is to return to recovery mode and select to reset factory settings. Leave this option for last! Although an effective option, resetting clears all the data you may have saved on your phone. Resetting factory settings means your phone will be as it was when you first bought it; which is great for solving software issues, but not so great for your data. That’s why we always recommend making sure you backup all your pictures, videos, music,  documents and whatever else you don’t want to lose before running the reset. Simply navigate back to recovery mode (using the power, volume up, and home button hold combination to enter), and select ‘Factory Reset.’
