Fixing Galaxy S9 that won’t boot up successfully

There are actually just a couple of procedures I want you to do to try and fix this problem. That’s all you need to do to know if this issue is with the hardware or just the firmware. While some users reported that this problem started only after a firmware update, there are times when it’s more than just that. If the problem isn’t fixed after doing what’s in this troubleshooting guide, then that’s the time you have to bring the phone to the shop so that a technician can check it up for you. But before that, here’s what you need to do:

First solution: Try doing the Forced Reboot on your Galaxy S9

I understand that your phone is stuck on the boot screen or loop and you may have already tried rebooting it countless times. But the forced reboot is different from the usual restart as it is a simulated battery removal. If you once owned devices with removable batteries, this method is the same as pulling the battery out of the phone to make it respond again. Only that on your Galaxy S9, you just have to simulate it by pressing a combination of buttons. But if your phone won’t boot up successfully due to a minor firmware-related problem, then the forced restart will fix it. Here’s how it’s done:

  1. Press and hold the Volume Down button and don’t release it yet.
  2. While holding down the volume button, press and hold the Power key as well.
  3. Keep both keys held down together for 15 seconds or until the Galaxy S9 logo shows on the screen.

Try doing the procedure a few more times if the problem isn’t fixed after the first try. If your phone still won’t boot up successfully even after doing this procedure, then move on to the next.

Second solution: Restart the phone in Recovery Mode

Even if your phone has some serious issues in its firmware, it should still be able to run in Recovery Mode as that’s usually the fail-safe for Android. Running the phone in this mode should be your next priority if the first procedure failed to fix the problem. It’s because you can do a couple of procedures that can fix this problem if only you were able to start the phone up in this environment. If successful, the first thing you have to do is wipe the cache partition so that the system cache will be replaced with a new one. This is how it’s done:

  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 Galaxy S9 logo shows, release all three keys.
  4. Your Galaxy S9 will continue to boot up into the Recovery Mode. Once you see a black screen with blue and yellow texts, proceed to the next step.
  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 the phone still won’t boot up successfully after this, then restart your phone up again in recovery mode and do the master reset. You may lose some of your important files and data as there’s no way for you to create a copy as you can’t access your phone. But that’s the compromise you have to take to get your phone working again. With that being said, follow these steps to master reset your device:

  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 Galaxy S9 logo shows, release all three keys.
  4. Your Galaxy S9 will continue to boot up into the Recovery Mode. Once you see a black screen with blue and yellow texts, proceed to the next step.
  5. Press the Volume down key several times to highlight ‘wipe data / factory reset’.
  6. Press Power button to select.
  7. Press the Volume down key until ‘Yes’ is highlighted.
  8. Press Power button to select and start the master reset.
  9. When the master reset is complete, ‘Reboot system now’ is highlighted.
  10. Press the Power key to restart the device.

If your phone still won’t boot up successfully after this or if you cannot make your phone to run in recovery mode, then it’s possible that there’s a really serious problem with the firmware. You may have to bring the phone to the shop so that a technician can fix the problem for you.
