How To Fix Samsung Galaxy S9 Restarts When Samsung Logo Is Displayed After Software Update
Problem: I have an android phone, specifically a Samsung S9. I am not sure of the android version that is on it but I update everytime one is available. It had an update available this morning so I done the update. When the phone went to restart it makes it to the Samsung Galaxy S9 Secured by Knox Powered by Android screen and then restarts. I have tried to get it into safe mode but it doesn’t stay on long enough to get that far. If I hold the lower volume button with the bixby button I will come to a screen and ask if I want to download a new operating system. It restarts continuously until the battery eventually dies. There is no error code that I can see. Any help would be appreciated. This happened on 2/1/2019. Thanks.
Solution: Since this issue occurred right after a software update then we will be concentrating our troubleshooting steps on the software side of the device. Before performing the troubleshooting steps listed below make sure that the phone is fully charged. If necessary connect it to its wall charger first and charge the device. You should also remove the microSD card of the phone if you have one installed.
Perform a soft reset
A soft reset which is usually done when a phone becomes unresponsive but is also recommended in this particular case as it will refresh the software.
- Press and hold the Power and Volume down key for up to 45 seconds.
- Wait as the device restarts.
Once the phone restarts check if the phone can now successfully turn on.
Check if the issue occurs in Safe Mode
An app you downloaded in your phone could be causing this problem. To check if this is the case you will need to start the phone in Safe Mode since only the pre-installed apps are allowed to run in this mode.
- Turn the phone off.
- Press and hold the Power key past the model name screen appearing on the screen.
- When SAMSUNG appears on the screen, release the Power key.
- Immediately after releasing the Power key, press and hold the Volume down key.
- Continue to hold the Volume down key until the device finishes restarting.
- When Safe mode appears in the bottom left corner of the screen, release the Volume down key.
In case the issue does not occur in this mode then it’s likely that the problem is caused by an app you downloaded. Find out what app this is and uninstall it. Once it is uninstalled start your phone normally
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 occurring 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 issue still occurs.
Perform a factory reset
One last troubleshooting step you should consider is a factory reset. This will revert your phone back to its original factory condition. 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.
Do not install any apps in your phone after the reset. Try to check first if the issue still occurs.
In case the issue persists even after performing the troubleshooting steps listed above then the best thing to do right now is to have the phone checked at a service center.
