How to fix Galaxy S9 that’s stuck on the logo and won’t boot up?

As long as the firmware hasn’t been modified in any way and remains intact, there’s always something you can do about this problem.

First solution: Try doing the forced reboot procedure

The good thing about this problem is that at least you know that you’re phone still powers on and that’s very important because you can still perform some basic troubleshooting procedures. That said, the first thing you must do is the forced reboot procedure which refreshes your phone’s memory and reloads all its apps and services.

To do this, press and hold the volume down button and power key together for 10 seconds or more. This will reboot your phone like it normally does but more often than not it does the trick.

If your phone, however, still can’t boot up completely, then move on to the next solution.

Second solution: Try to boot the phone up in Safe Mode

You need to do this to know if the problem is caused by some third-party applications. When in safe mode, all downloaded apps are temporarily disabled so if one of them is preventing your device to boot up, then your Galaxy S9 should start normally into this mode. Here’s how you do it:

1. Turn the device off.
2. Press and hold the Power key past the model name screen appearing on the screen.
3. When SAMSUNG appears on the screen, release the Power key.
4. Immediately after releasing the Power key, press and hold the Volume down key.
5. Continue to hold the Volume down key until the device finishes restarting.
6. When Safe mode appears in the bottom left corner of the screen, release the Volume down key.

Assuming you’ve successfully booted up your phone into this mode, the next thing you must do is reboot it into normal mode as that would usually work. At least we know at this point that  third-party apps have something to do with it. Find out which apps are preventing your phone from booting up and uninstall them.

Third solution: Try to reboot your phone in Recovery Mode

You only have to do this if your Galaxy S9 is also stuck on the boot screen while trying to boot it up in safe mode. In recovery mode, there’s a couple of things you can do that will have a great impact on your phone especially that it can no longer boot up successfully. The first thing you should do if you can get your device to boot up in this mode is to wipe the cache partition.

1. Turn off the device.
2. Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
3. When the Android logo displays, release all three keys.
4. An ‘Installing system update’ message will show for 30 – 60 seconds before the Android system recovery menu options appear.
5. Press the Volume down key several times to highlight wipe cache partition.
6. Press Power key to select.
7. Press the Volume down key to highlight yes, them and press the Power key to select.
8. When the wipe cache partition is complete, Reboot system now is highlighted.
9. Press the Power key to restart the device.

If it’s still stuck on the same screen after wiping the cache partition, then you have no other choice but to perform the Master Reset. It’s effective enough to fix firmware related issues including this one but you may lose some of your important files and data as everything that’s saved in the phone’s internal storage will be deleted during the reset process.

1. Turn off the device.
2. Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
3. When the green Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
4. Press the Volume down key several times to highlight ‘wipe data / factory reset’.
5. Press Power button to select.
6. Press the Volume down key until ‘Yes — delete all user data’ is highlighted.
7. Press Power button to select and start the master reset.
8. When the master reset is complete, ‘Reboot system now’ is highlighted.
9. Press the Power key to restart the device.
