How To Fix Samsung Galaxy S9 Bootloop When Installing Android Pie Update

Problem:  I just wanted to update my Samsung Galaxy S9 with the newest Update distributed by Samsung and now it is stuck in a boot loop. I wanted to do a Master Reset but holding the bixby and the volume up button and then the power button which led me to a screen where it said a software update was being performed. At 28% the “update” crashes (every single time) and my phone is once again stuck in a boot loop. Is there anything else I can do? I did read your advice on the steps to try and fix the issue, however it is stuck in this loop and will not turn off or on, phone was plugged in for a few hours so it’s not a battery issue, it’s just stuck in this endless loop. So I can’t even get to the hard start option or even start it in safe mode, it just bounces between trying to finish the update and turning on and off. No combinations of buttons does anything except getting to the “odin” screen. Please help. Thank you in advance for your quick reply.

Solution: Since this is most likely a software related problem we will be concentrating our troubleshooting efforts on the software of the device. Before proceeding with the troubleshooting steps listed below make sure to remove the microSD card of the phone if you have one installed.

Do a Soft Reset

The first thing that you will need to do in this particular case is a soft reset. This will usually fix issues caused by minor software glitches as it will refresh the phone software. This is also called as a simulated battery pull as it disconnects the phone from the battery.

  • Press and hold the Power and Volume down key for up to 45 seconds.
  • Wait as the device restarts.

Check if the phone will update successfully.

Update from a computer using Smart Switch

Make sure to backup your phone data before performing this procedure.

  • Download and install Samsung Smart Switch that is compatible with your computer from http://www.samsung.com/us/support/smart-switch-support/#!/.
  • Connect the cable to a compatible USB port on your computer.
  • Connect the other end of the cable to your mobile device.
  • Allow your computer to install any required drivers for your device. This process may take a few minutes.
  • Open Smart Switch on your computer, and allow it to make the connection.
  • If a software update is available for your device, Smart Switch will automatically prompt you to update. At any time, you can click Update.
  • Click Update to begin downloading the necessary files.
  • Click OK to proceed.
  • Your device may turn off and on a few times during the update process.
  • Once complete the device will return to the Home screen.

In case the phone software does not get updated then proceed with the additional troubleshooting steps listed below.

Wipe the cache partition of the phone

The phone system cached data is used to speed up the access to your phone apps. Sometimes this data can get corrupted which results in issues occuring on the device. To check if a corrupted cached data is causing the problem you will need to wipe the cache partition of the phone from the recovery mode.

  • Turn off the phone.
  • Press and hold the Volume Up key and the Bixby key, then press and hold 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 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.

Check if the problem still occurs.

Perform a factory reset

In case the issue still persists then you should consider performing a factory reset. Take note that this will erase your phone data.

  • Turn off the phone.
  • Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  • 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).
  • Press the Volume down key several times to highlight ‘wipe data / factory reset’.
  • Press Power button to select.
  • Press the Volume down key until ‘Yes — delete all user data’ is highlighted.
  • Press Power button to select and start the master reset.
  • When the master reset is complete, ‘Reboot system now’ is highlighted.
  • Press the Power key to restart the device.

In case the issue still persists after the reset then you should bring the phone to a service center and have it checked.
