How to troubleshoot Galaxy S7 that’s unable to boot up
Problem: I have a Samsung S7 that started to give me problems on a flight to Singapore. It would restart and then not allow me access to my keyboard. I would reboot and then finally get the keyboard just to have it reboot again. It is now stuck in reboot mode with logo stuck on.
Solution: If you are certain that your phone doesn’t have a hardware issue or liquid damage, then it is evident that a firmware-related problem is causing it. More often, this issue occurs if the system underwent an upgrade and some files and data have been corrupted during the process. If the system can no longer recognize the files, there is a possibility that the firmware will crash and that’s the reason the device stuck in the logo. So, what we have to do now is to do some troubleshooting on your phone to determine if software or hardware problem triggered it.
Step 1: Forced reboot your phone for it might be a system glitch
This is a simulated battery disconnect procedure wherein it refreshes the memory of the device and close all applications running in the background. So, if the issue is caused by a system glitch, then, this method may fix it. Just press and hold the Power and Volume Down buttons at the same time for 10 seconds until the device reboots. But if your phone is still stuck in bootloop after this, you can proceed and do the next step.
Step 2: Restart the device in Safe mode
When booting in safe mode you are putting the device in another diagnostic state wherein all third-party apps will be disabled temporarily. If the problem is due to a third-party app, then you should be able to boot in safe mode without any problem. To boot in safe mode follow these steps:
- Press and hold the Power key.
- When Samsung Galaxy S7 logo appears, release the Power key and immediately hold the volume down key.
- Continue holding the Volume Down key until it finishes its rebooting.
- When “Safe mode” appears on the screen immediately release the Volume Down key.
Assuming you have successfully booted your phone up in this mode, the next thing you should do is find the app that’s causing the problem and then uninstall it. This should fix the problem and when you boot your phone back in normal mode, it should go through smoothly.
Here’s how you uninstall an application from your phone:
- From any Home screen, tap the Apps icon.
- Tap Settings.
- Tap Apps.
- Tap the desired application in the default list or tap Menu icon > Show system apps to display pre-installed apps.
- Tap Uninstall.
- Tap Uninstall again to confirm.
Step 3: Delete all the system caches
Although you didn’t mention that the firmware has been upgraded, there is a chance that due to outdated caches an issue like this occurred. This time, we have to wipe the cache partition so that the old system caches will be deleted and replaced. Here’s how you do it:
- Turn off the device.
- Press and hold the Volume Up key and the Home key, then press and hold the Power key.
- When the device logo screen displays, release only the Power key.
- When the Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
- Press the Volume down key several times key to highlight ‘wipe cache partition’.
- Press the Power key to select.
- Press the Volume down key to highlight ‘yes’ and press the Power key to select.
- When the wipe cache partition is complete, ‘Reboot system now’ is highlighted.
- Press the Power key to restart the device.
After deleting the system caches and your phone failed to boot up successfully, then, your last resort is to do a reset.
Step 4: Backup your files and reset your phone
The purpose of the reset is to bring the device back to its factory default settings. It also means all files saved in the internal storage will be deleted. So, before you continue to the steps it is imperative that you should create a backup for everything important, either you transfer it to the SD card or to your personal computer so that you can easily restore after the issue is resolved. After the backup and just before you actually reset your phone, make sure to disable the Factory Reset Protection by removing your Google account from your phone so that you won’t be locked out after the reset:
- From any Home screen, tap the Apps icon.
- Tap Settings.
- Tap Cloud and accounts.
- Tap Accounts.
- Tap Google.
- Tap your Google ID email address. If you have multiple accounts setup, you will need to repeat these steps for each account.
- Tap Menu.
- Tap Remove account.
- Tap REMOVE ACCOUNT.
Now follow these steps to reset your phone…
- Turn off your Samsung Galaxy S7.
- 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.
- When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
- 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.
- Using the Volume Down key, navigate through the options and highlight ‘wipe data / factory reset.’
- Once highlighted, you may press the Power key to select it.
- Now highlight the option ‘Yes — delete all user data’ using the Volume Down key and press the Power button to select it.
- Wait until your phone is finished doing the Master Reset. Once completed, highlight ‘Reboot system now’ and press the Power key.
- The phone will now reboot longer than usual.
After you did the master reset and your phone is still unable to boot, bring it to the local shop in your area so that it can be checked and tell the tech that you already did all the necessary procedures but the device still unable stuck during boot up. This should help the tech determine the problem right away.
