How to fix your Samsung Galaxy S6 Edge Plus that won’t boot up after a firmware update [Troubleshooting Guide]

Many owners await for the roll out of the Android 7.1 #Nougat update and while anticipation rises, carriers and service providers are trying to prepare their carried devices for a major update this year. So, minor updates and security patches were rolled out and owners don’t have any option but to download and install said updates. The problem is there were some issues that started after those updates and one of them is about the #Samsung Galaxy S6 Edge Plus (#S6EdgePlus) that can no longer boot up successfully.

So, in this post, I will tackle this issue in a bid to help our readers their problems with their devices. It’s a firmware related problem so we only have to rule out possibilities that some apps are causing it then go after the firmware. For owners who have encountered such issue after an update, don’t worry about whether or not it’s a hardware problem because it, certainly, is not.

Troubleshooting Galaxy S6 Edge+ that can’t boot up successfully after an update

The purpose of this troubleshooting guide is for us to know the reason why the problem occurs. Once we know what the cause is, we can easily try to find a solution, so without further adieu, this is what you have to do…

Step 1: Perform the Soft Reset procedure

I understand that your phone powers on but cannot boot up. It might got stuck on the logo or the black screen while starting up. Since the S6 Edge+ doesn’t have removable battery, we cannot do the usual battery pull procedure but instead, we can do the soft reset procedure that has the same effects. Just press and hold the Volume Down and Power keys together for 15 seconds so that the phone will reboot. If it won’t boot up successfully, then the next step might help.

Step 2: Attempt to boot it up in safe mode

Considering the fact that this problem started after a firmware update, there’s a chance that some third-party apps are no longer compatible with the new system or some of them keeps crashing and affected the system’s normal operation. As a result, you have a phone that won’t boot up. So, booting in safe mode will actually isolate the problem–it will tell you right away if it’s caused by a third-party app or pre-installed one. Here’s how you do it…

  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.

If the phone booted up successfully in safe mode, then we’re half way to fixing the problem. All we need to do now is find the apps that are possibly causing the issues and uninstall them.

  1. From any Home screen, tap Apps.
  2. Tap Settings.
  3. Scroll to ‘APPLICATIONS,’ then tap Application manager.
  4. Swipe right to the ALL screen.
  5. Scroll to and tap suspected app.
  6. Tap Clear cache.
  7. Tap Clear data button, then OK.

I understand it’s not easy to find apps that are causing the problem so if you don’t have a clue which app to uninstall, I suggest you just backup your data and files and then do the factory reset. This will delete all your files and data, reset your phone to default settings and uninstall third-party apps.

  1. From the Home screen, tap the Apps icon.
  2. Find and tap the Settings icon.
  3. Under the ‘Personal’ section, find and tap Backup and reset.
  4. Tap Factory data reset.
  5. Touch Reset device to proceed with the reset.
  6. Depending on the security lock you used, enter the PIN or password.
  7. Tap Continue.
  8. Touch Delete all to confirm your action.

On the other hand, if your device failed to boot up in safe mode, then try to do the next step.

Step 3: Attempt to boot your phone up in recovery mode

Do this only if your phone didn’t start up in safe mode. It could be that the firmware itself has a problem and that’s what’s preventing your phone from booting up successfully. However, if the phone powers up but gets stuck during the bootup process, there’s a big chance it can boot up in recovery mode successfully as the Android interface won’t be loaded. If successful, proceed with the wiping of cache partition or the master reset. Here’s how you do those procedures…

  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.

How to Master Reset Galaxy S6 Edge+

  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 remained after this or if the phone failed to boot up in recovery mode, then it’s time you sent it in for checkup and/or repair.
