How to troubleshoot Galaxy S7 Edge that won’t boot up after Android 7 Nougat update

Problem: My phone, an S7 Edge, has recently been updated to the newest operating system. I still remember when it was updated a few months ago, after the update it rebooted and after that it worked perfectly with noticeable improvements. This time around, however, it got stuck on a black screen. What happened is that the update was downloaded and installed but by the time it rebooted, it didn’t go through. I hasn’t reach the home screen and I can no longer use it. I’m not really sure what happened or what I have to do to fix this that’s why I’m seeking for your assistance. Please help.

Troubleshooting: Some caches and data may have been corrupted during the update process and that might be the reason why your phone can no longer boot up successfully. Such is the case to most of the problems that many owners encountered shortly after firmware updates regardless whether they were minor or major ones. In this case, the following are the steps you can actually try in a bid to fix this problem or make your phone boot up successfully.

Step 1: Perform the Forced Restart procedure

This must be the very first thing you have to do. I understand if you already tried rebooting your phone several times. This procedure, however, is basically the same as the reboot only that does the simulated battery disconnect. If you once own a smartphone with a removable battery, you may have tried doing the battery pull procedure when your device froze. This is the equivalent of that only that this time, your Galaxy S7 Edge doesn’t have a user-removable battery.

What you have to do is press and hold the Volume Down button and the Power key together for 10 to 15 seconds. Provided there’s still enough battery and that the problem was caused by a system crash due to recent firmware update, then your device should reboot once you’ve performed this procedure. Otherwise, try to do the next steps.

Step 2: Try to charge your Galaxy S7 Edge to see if would respond

It is imperative that at this point in our troubleshooting, we can confirm that your phone responds whenever it detects electric current flowing through its circuits because if it doesn’t, we’re not actually dealing with a firmware-related issue but a hardware problem that may probably include the battery. But let’s not get ahead of ourselves here, instead follow the simple procedure below:

  1. Plug the charger to a wall outlet with its cable attached.
  2. Now connect your Galaxy S7 Edge via the USB cable.
  3. If it doesn’t respond, leave it charging for, at least, ten minutes.
  4. If it failed to charge after ten minutes, press and hold the Volume Down button and the Power key for 10 to 15 seconds while charging.

If the phone won’t charge at all, then try to go through our not charging troubleshooting guides:

On the other hand, if your device charges the way it should but still not being able to continue the boot up process, then the next step might be of help.

Step 3: Try to boot up your Galaxy S7 Edge in Safe Mode

We are now trying to validate if your phone is still capable of booting up even with all third-party apps temporarily disabled because if it can, then we might just be dealing with compatibility issue. That means that some of the third-party apps may not be compatible with the new firmware and during boot up, they may be creating conflicts in the system that prevents the phone from reaching the home screen normally.

So, to start your phone up in safe mode, follow these steps:

  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.

At this point, if you’ve reached the home screen or if your phone has successfully booted up in its diagnostic state, then our suspicion that maybe one or some of your downloaded apps is causing the problem has been confirmed. So, all you gotta do is find them and uninstall suspected apps. If you find it hard to know which app is causing the problem, then I suggest you backup all your files and data while in safe mode and just do the factory reset:

  1. From the Home screen, tap the Apps icon.
  2. Find and tap Settings and then touch Backup and reset.
  3. Tap Factory data reset and touch Reset device.
  4. If you have screen lock feature turned on, enter your password or PIN.
  5. Touch Continue.
  6. Tap Delete all to confirm your action.

If, however, your phone cannot boot up in safe mode successfully, then you have to try the next step.

Step 4: Try booting your phone into Recovery Mode and try wiping the cache partition

Since your device failed to boot up in safe mode, it’s time you tried booting it up in another mode. This time, we need to try to boot your device into the recovery mode and if successful, try wiping the cache partition since the problem is more on the firmware side than hardware. Here’ show you do this:

  1. Turn off the phone.
  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 wiping the cache partition. Once completed, highlight ‘Reboot system now’ and press the Power key.
  9. The phone will now reboot longer than usual.

If wiping the cache partition didn’t fix the problem, you should try to do the master reset. However, you must try to boot up your phone in safe mode so you would have a chance in backing up your files and data. Follow these steps to reset your phone:

  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. NOTE: It doesn’t matter how long you press and hold the Home and Volume Up keys, it won’t affect the phone but by the time you press and hold the Power key, that’s when the phone starts to respond.
  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. NOTE: The “Installing system update” message may show on the screen for several seconds before displaying the Android system recovery menu. This is just the first phase of the entire process.
  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.

If the phone can’t still boot up after the master reset, then you need help from a technician to reinstall the firmware.

How to troubleshoot your Galaxy S7 Edge that got stuck on the logo during boot up after Nougat update

Problem: Hi! There seems to be a problem with my S7 Edge. It has updated its operating system a couple of days ago and then it stopped working. I mean, it sure does power on but it gets stuck on the Samsung logo and won’t proceed. I’ve already tried leaving it in that state for a couple of hours but nothing happened. I tried rebooting it a lot of times already but nothing seems to happen. I am hoping you guys have something to suggest to fix this problem. Thanks a lot.

Troubleshooting: Your device might be experiencing a firmware issue after that update. It could be that some of the files are corrupted or damaged during the update process. This is a common issue since the release of the new update (Nougat). Actually, we’ve received a lot of complaints about it, mostly from our Samsung Galaxy S7 Edge readers. Some of them experienced this just as they experienced from the last update (Marshmallow), they find it a ‘hassle’ update. However, as long as it’s a firmware issue, it can be fix. Just like the first issue above, we recommend performing some basic troubleshooting procedure to narrow down the issue.

You can start by doing a force reboot to your device, just press and hold the button for 7-10 seconds and allow your device to reboot. It will do a simulated battery pull procedure, you can refer on above topic for more information. Since your issue is related on the first issue above, then you can follow and perform other troubleshooting procedures above.

If in case all mentioned procedures didn’t fix the issue, then you can proceed and perform master reset, but first, you can try plugging your device to a PC to see if it will recognize your device. If so, we recommend making backups of your important files, that would be your best option left available before performing the master reset procedure. Otherwise, you don’t have any chance of making backups if you already brought it to a tech.

Hopefully, your device will be fixed after performing the master reset, if not, and it’s still stuck on the Samsung logo and won’t proceed then it could be experiencing a more serious problem that cannot be done by performing a basic troubleshooting procedure. It is time to let the specialist handle the situation, bring it to the nearest Samsung service center.

How to troubleshoot a Galaxy S7 Edge that gets stuck on the black screen after an update

Problem: There was an update that I downloaded a few days ago. The phone rebooted after the update and I was actually able to use it after that but I noticed the performance deteriorated instead of being boosted. So, I tried to reboot it but it didn’t boot up successfully but got stuck on the black screen after the logo. I’m not sure what happened let alone know what I have to do next to fix it. So, if you guys know how, please help me. Thanks a bunch!

Troubleshooting: Since this issue happened after installing the software update, then your device is obviously experiencing a firmware issue, it could be that some files are corrupted or incompatible to the new update. However, we don’t know the issue yet, it could be a minor system glitch or it could be worse, a hardware-related issue. To narrow it down you need to perform the basic troubleshooting procedures on your phone to give you insight on what caused the problem.

In many cases, due to glitch in the system that could be one of the reasons that your phone’s screen went black without apparent reason. So, the first thing that you should do is to do forced reboot on your device and observe if the issue still happening. If so, you can perform the next procedure.

If the device refused to boot in forced reboot procedure, try to connect it to the charger and wait if it will respond. If it will, then there should be other factors triggered the issue. Try to boot your phone in Safe mode and wait if the device will boot up normally. In this procedure, all third-party applications will be disabled temporarily and only the pre-installed apps will run in the system. If the issue is not happening while in this state, then  third-party apps triggered it.

However, if the problem persists then most-likely it is a firmware issue wherein the system cache had been corrupted after the update. To fix the issue, you can wipe the cache partition of the phone by following the procedure above. This procedure will delete all old caches in the system to force the device to create newer and compatible caches in the system.

But if all procedures didn’t worked on your phone, then your last resort is to perform master reset. Take note that this procedure will delete everything including your files, contacts, photos and music saved on your phone. So, before resetting the device make sure to backup everything because all will be deleted. To do the reset; follow the steps above.
