The #Samsung Galaxy S7 Edge (#S7Edge) is finally getting updated to Android 7.1 #Nougat but it appears like there are still a lot of users who are bugged by a problem or two. One of the most common is that the phone can no longer boot up to the home screen shortly after the update. There are even cases wherein the device couldn’t finish the reboot after installation because it gets stuck during boot up.

Troubleshooting Galaxy S7 Edge that can no longer boot after the Nougat update

By using deductive troubleshooting, we will be able to pinpoint what caused the problem and formulate a solution that may be able to solve it. There’s no guarantee that it will be fixed by following the steps below, however, we suggest you take time trying to fix the problem on your own to save you from a lot of trouble should it be fixed by one of the following procedures.

Step 1: Try to see if the phone restarts when you Force Reboot your device

Obviously, the device doesn’t boot up successfully using the normal method and I’m sure you’ve already done it a hundred times. So, this time, try to force reboot your phone to see if the problem gets fixed. It is equivalent to the battery pull procedure we often do to devices with removable battery. It’s very effective in dealing with minor firmware and hardware issues so it’s worth doing it. Just press and hold the Volume Down button and the Power key for 15 seconds to see if the phone reboots normally and successfully. If so, then, at this point, the problem is solved but if the issue remains, then move on to the next procedure.

Step 2: Attempt to boot it up in Safe Mode

Some apps may not be compatible with the new firmware of your device and that may have prevented it from booting up normally after the update. Therefore, we need to isolate the issue to know if your third-party apps have something to do with it or if it’s all with the pre-installed ones or the firmware itself. Try to boot your device in safe mode to temporarily disable all third-party apps…

  1. Turn your Galaxy S7 Edge off.
  2. Press and hold the Power button.
  3. Once the ‘Samsung Galaxy S7 Edge’ logo appears, release the Power key and immediately press and hold the Volume Down button.
  4. Continue holding the button until the phone finishes rebooting.
  5. Once you see the text “Safe mode” at the bottom left corner of the screen, release the Volume Down button.

If the phone successfully booted up in safe mode, then your third-party apps have something to do with it but the question is which app is causing the problem?

There’s no easy way to know which app is causing the problem so I suggest you open the Play Store and view your apps. Try to find ones that need to be updated and try to update them and then boot your phone in normal mode to see if that fixes the problem. Also, if you have apps that suspect are causing the problem, clear their caches and data or even uninstall them and reboot your device normally.

How to clear app cache and data

  1. From the Home screen, tap the Apps icon.
  2. Find and tap on Settings.
  3. Touch Applications and then Application manager.
  4. Swipe to ALL tab.
  5. Find and touch the app in question.
  6. Touch the Force Close button first.
  7. Then, tap Storage.
  8. Tap Clear cache and then Clear data, Delete.

How to uninstall apps from Galaxy S7 Edge

  1. From the Home screen, tap the Apps icon.
  2. Find Settings and tap on it.
  3. Scroll to and tap Applications.
  4. Tap Application manager.
  5. Find the app you want to uninstall and tap on it.
  6. Touch the ‘UNINSTALL’ button.
  7. A new dialog box will pop up, tap OK to confirm your action.

However, if the phone  is still not booting up in safe mode, then there’s a couple more things you can try.

Step 3: Attempt to start your phone up in Recovery Mode

If the phone can boot up in safe mode, then it can start in this mode up but if not then there’s still a chance that it can boot up in Recovery Mode depending on how serious the problem is. Therefore, it’s worth it to try this method because if successful, you can try a couple of things to try to fix this problem. The first thing you can do is wipe the cache partition to delete all system caches…

  1. Turn off your Samsung Galaxy S7 Edge.
  2. Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  3. When the Samsung Galaxy S7 Edge shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  4. When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
  5. Using the Volume Down key, navigate through the options and highlight ‘wipe cache partition.’
  6. Once highlighted, you may press the Power key to select it.
  7. Now highlight the option ‘Yes’ using the Volume Down key and press the Power button to select it.
  8. Wait until your phone is finished doing the Master Reset. Once completed, highlight ‘Reboot system now’ and press the Power key.
  9. The phone will now reboot longer than usual.

If this doesn’t fix the problem, then you can try to perform the Master Reset. This will delete all your files and data but you actually don’t have much of an option now. So, if you decide to go with it, here’s how…

  1. Turn off your Samsung Galaxy S7 Edge.
  2. Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  3. When the Samsung Galaxy S7 Edge shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  4. When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
  5. Using the Volume Down key, navigate through the options and highlight ‘wipe data / factory reset.’
  6. Once highlighted, you may press the Power key to select it.
  7. Now highlight the option ‘Yes — delete all user data’ using the Volume Down key and press the Power button to select it.
  8. Wait until your phone is finished doing the Master Reset. Once completed, highlight ‘Reboot system now’ and press the Power key.
  9. The phone will now reboot longer than usual.

Should these procedures fail, it means that there’s something really wrong with the firmware and it may need to be re-flashed. You have to bring your phone to the tech and let him take care of it.
