How to troubleshoot Galaxy S7 Edge that won’t turn on after an update

Problem: I have a Samsung S7 Edge and I updated my phone overnight and in the morning it’s not working since 3 days it’s not turning on only I get black screen with Samsung sign I keep charging but no use kindly advice what to do with my phone. thanks!

Solution: As you said the issue occurred after the update, it is evident that this might be a software-related problem wherein some files may have been corrupted and that might have triggered the issue.The good thing is you can fix this issue on your own without spending money from your pocket to pay for the tech. So, what we gonna do now is to determine the problem by performing the basic troubleshooting procedures on your phone.

Step 1: Do the Forced Restart procedure

The forced restart is a simulated battery disconnect in which, the equivalent of the battery pull procedure we do to phones with removable battery. Through forced reboot the memory will be refreshed and if this is just a glitch, then this procedure will definitely take care of the problem.

To do so, just press and hold the Power and Volume Down buttons simultaneously for 10 seconds and wait until the device reboots. But if your phone still refuses to power on while doing the method, you can proceed to the next step.

Step 2: Try to boot your phone up in Safe mode

By booting it in safe mode we will have to validate if the device is able to turn on while the third-party apps are disabled temporarily. It’s possible that one or some of the apps you installed is causing the problem that’s why you need to try doing this to know how the phone responds.

  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 refuses to turn on in safe mode, try the next step.

Step 3: Attempt to start the phone in Recovery mode

We simply want to know if your phone is still capable of powering up its hardware and since it won’t respond when you tried booting it up in safe mode, you should try to start it up in Android system recovery as it’s considered the fail-safe for all Android devices.

If successful, there are a couple of things you can do and that’s to wipe the cache partition or do the master reset.

  8. Wait until your phone is finished wiping the cache partition. Once completed, highlight ‘Reboot system now’ and press the Power key.
  9. The phone will now reboot longer than usual.
