How to fix your Samsung Galaxy S7 Edge that won’t power on after an update [Troubleshooting Guide]

Some of the Samsung Galaxy S7 Edge owners are just receiving the Android Nougat update and we have readers who reported their device no longer turns on after the update. After reading some of the problems, we noticed that some of them are actually “not booting up” issues but their owners labeled them as “not turning on.” So, we have to differentiate these two problems before we proceed.

When you say “not turning on,” it means that your device doesn’t power up–there’s no response when you press the power key. The screen won’t flicker, the phone doesn’t respond, there’s no sound, no everything. It means the phone is completely dead and unresponsive.

However, when you say “not booting up,” the phone powers on and you will immediately notice it responds but the screen may remain blank or the phone may be stuck somewhere during start up.

Now that we’ve made clear the distinction between these two problems, we can proceed with our troubleshooting. So, in this post, I will walk you through in troubleshooting your S7 Edge that won’t turn on after an update. We will take into consideration each possibility and rule them out one by one until it becomes clearer to us what the problem really is. If you own this phone and are currently bugged by the same issue, continue reading as this post may be able to help you.

What to do if your Galaxy S7 Edge won’t power on after update

Problem: Hi, We recently performed the latest software update on my Galaxy S7 Edge and it worked fine. Until we used the camera, while filming the phone screen turned blank and began to get very hot. Since we have attempted to place it on charge to no response of lights etc. We have tried to boot the phone in numerous ways, performing all the button restarts to a blank screen. The phone appears lifeless after the update. Any ideas?

Solution: Since the issue started after the update it’s not far that this is just a software-related problem. Most of the time, due to corrupted files and data the firmware is having a hard time recognizing it and that may be the reason that the system will crash your phone refuses to power on. So, what we have to do now is to isolate the issue through performing the basic troubleshooting to determine what really triggered the issue.  Don’t you worry, these procedures won’t harm your phone nor delete the important files saved in it.

Step 1: Perform forced reboot for it might be a system glitch

System crash is one of the common denominator that the device is unable to power on and become unresponsive. So, through forced reboot we will have to refresh the memory of your phone and close all apps that might caused the issue. This is how you do the force reboot:

  1. Press and hold the Volume Down and Power keys together for 10 seconds.
  2. The phone will reboot successfully provided that it was just a system crash and that there’s enough battery left.

But if the device still won’t power on after the procedure, follow the next method.

Step 2: Attempt to boot it in safe mode

By booting it in safe mode we can determine if there’s an app responsible on the issue. Remember, this is just an android environment wherein all third-party apps will be disabled temporarily. So, if your phone boots up normally while in this method, then an app caused the problem. This time, you can uninstall the suspected apps starting from the recent one you installed until the issue is resolved.

  1. Press and hold the Power key.
  2. As soon as you can see the ‘Samsung Galaxy S7 Edge’ on the screen, release the Power key and immediately hold the Volume Down key.
  3. Continue holding the Volume Down button until the device finishes rebooting.
  4. You may release it when you can see ‘Safe mode’ in the bottom left corner of the screen.

If the phone still refuses to boot up in this mode, then try the next one.

Step 3: Attempt to start the phone in Recovery mode and delete system caches

In clearing the cache partition, we are deleting all cached files stored in the directory to force the device to create newer and fresher ones that are compatible with the new system. Also, in doing this procedure the hardware components inside will be powered-up, so, if this is just a firmware issue your phone will boot up without a problem. 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 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.

After clearing the cache partition observe closely if your phone is able to turn on, if it is, then corrupted files might caused the issue. However, if it persists you don’t have a choice but to do the reset.

Step 4: Bring your phone back to its factory settings

Assuming you’ve successfully booted your phone up in recovery mode and wipe off the cache partition but the problem remained, then this must be the next procedure you should do. In this method, we will bring back your phone to its default settings by deleting all stored files like: contacts, music, videos and all third-party apps installed in the firmware. So, before you follow the steps we recommend that you should create a backup for all of it. But the good thing about resetting is, all bugs and other issues that conflict the system will be removed from the firmware. Just follow these steps:

  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 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.
