Troubleshooting Galaxy S6 Edge that keeps rebooting after a firmware update

Frequent and random reboots happen from time to time but they often occur after a firmware update. It’s a sign that your phone experiencing either a minor problem with the firmware or a complex issue that involves both the system and the hardware. With all that being said, here’s what you need to do in a bid to fix the problem…

Step 1: Attempt force reboot the phone

Okay, so the problem is random reboots and your device may have already rebooted more than a hundred times since the problem started. Why would you want to reboot your phone again to see if the problem gets fixed?

If you’re a long time owner of a cellular phone, you should have encountered issues before that could be fixed by pulling the battery out for a few seconds. The Forced Reboot procedure is like that–it does the simulated battery disconnect on your S6 Edge, which apparently doesn’t have a removable battery.

Press and hold the Volume Down button and while doing that, press and hold the Power key and keep both keys held for 15 seconds. Your phone should reboot normally and hopefully this fixes the problem if it was only due to a minor firmware or hardware glitch. However, if the problem remained, then it’s time to move on to the next step.

Step 2: Boot up your phone in Safe Mode and continue using it while in that state

The purpose of this step is for you to know if the problem would still occur even if all third-party apps are temporarily disabled because if not, then it’s clear as day that one or some of the apps installed on your device is causing the problem. Therefore, you just have to find the culprits and uninstall them one by one until the problem disappears. By the way, here’s how you boot your phone up in safe mode…

  1. Press and hold the Volume Down and Power keys for 20 to 30 seconds.
  2. Once you see the Samsung logo, release the Power key immediately but continue pressing the Volume Down key.
  3. Your phone should continue booting up and you will be prompted to unlock your phone as usual.
  4. You will know if the phone successfully booted in safe mode if the text “Safe mode” is displayed at the lower-left corner of the screen.

Step 3: Delete the system caches to have them replaced

These are the temporary files the system creates and uses every time the user launches apps. Caches make the performance of your device smoother but when they get corrupted, things can also go south if the system continues to use them. So, deleting them will definitely help as they’ll be replaced with new ones. Here’s how you delete the system caches…

  1. Turn off the device.
  2. Press and hold the following three buttons at the same time: Volume Up key, Home key, and Power key.
  3. When the phone vibrates, release the Power key but continue to press and hold the Volume Up key and the Home key.
  4. When the Android System Recovery screen appears, release the Volume Up and Home keys.
  5. Press the Volume Down key to highlight ‘wipe cache partition.’
  6. Press the Power key to select.
  7. When the wipe cache partition is complete, ‘Reboot system now’ is highlighted.
  8. Press the Power key to restart the device.

Step 4: Perform the Master Reset

Lastly, if all else fails and your phone is still rebooting randomly, then you will have to backup your files and data including your messages and contacts as they will be deleted once you reset your device. A reset is necessary to rule out the possibility that it’s just a minor firmware issue. After the reset, you will have to setup your phone again to be able to use it normally. Here’s how you reset your device…

  1. Turn off your Samsung Galaxy S6 Edge.
  2. Press and hold the Volume Up, Home and Power keys together.
  3. When the device powers on and displays ‘Power on logo’, release all keys and the Android icon will appear on the screen.
  4. Wait until the Android Recovery Screen appears after about 30 seconds.
  5. Using the Volume Down key, highlight the option, ‘wipe data/factory reset’ and press the Power key to select it.
  6. Press the Vol Down button again until the option ‘Yes — delete all user data’ is highlighted and then press the Power key to select it.
  7. After the reset is complete, highlight ‘Reboot system now’ and hit the Power key to restart the phone.

If the problem, however, still occurs after the reset, then it’s clear enough that the phone is currently experiencing a serious firmware issue. The new firmware may need to be re-installed for the phone to work normally again.
