How to fix Galaxy Note9 stuck on boot screen (bootloop) issue

One of the most common problems in Samsung Galaxy devices is Android being unable load normally, causing the phone to restart once it reaches the Samsung screen. This issue is also known as bootloop as the device is forced to continuously loop after booting up. Many users encounter this problem after tampering with the software but some also reports this problem on the Galaxy Note9 even if they did nothing differently.

How to fix Galaxy Note9 stuck on bootloop or boot screen

Troubleshooting bootloop issue on Galaxy Note9 can be done by performing the following steps:

Solution 1: Force reboot

Sometimes, Android may fail to load normally due to a temporary bug. To see if the bug can easily be fixed by refreshing the system, you can simulate the effect of disconnecting the battery. Here’s how that’s done:

Press and hold the Power + Volume Down buttons for approximately 10 seconds or until the device power cycles. Allow several seconds for the Maintenance Boot Mode screen to appear.
From the Maintenance Boot Mode screen, select Normal Boot. You can use the volume buttons to cycle through the available options and the lower left button (below the volume buttons) to select. Wait for up to 90 seconds for the reset to complete.

Solution 2: Restart device to Recovery Mode

When faced with bootloop issue on any Samsung Galaxy device, the most effective solution is often a master reset. Also known as factory reset, this solution can only be performed when a device can successfully be booted to Recovery Mode. Bootloop obviously won’t allow you to open Settings app so the only way to reset the software to their defaults is by accessing Recovery Mode. This is how it’s done:

Turn off the device. This is important. If you can’t turn it off, you’ll never be able to boot to Recovery Mode. If you are not able to shut the device off regularly via the Power button, wait until the phone’s battery is drained. Then, charge the phone for 30 minutes before booting to Recovery Mode.
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).

If you are able to restart your Galaxy Note9 to Recovery Mode, there’s a chance you may be able to fix your problem with factory reset or master reset. Under Recovery Mode, there are a number of options that you can do such as clear the cache partition and factory reset. Below are the complete steps to do each one.

Clear Note9 cache partition

Turn off the device.
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 cache partition’.
Press Power button to select.
Press the Volume down key until ‘yes’ is highlighted and press the Power button.
When the wipe cache partition is complete, “Reboot system now” is highlighted.
Press the Power key to restart the device.

Perform factory reset

Turn off the device.
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.

Solution 3: Drain battery and restart

Some bootloop cases are due to unique bugs in a certain device. If your Note9 was working perfectly fine before it got stuck in bootloop, you may be able to fix it by allowing it to drain its battery, then restarting it afterwards.

Solution 4: Flash stock firmware

If you are unable to load to Recovery Mode, or if cache partition wipe and factory reset won’t make a difference, you should consider doing a more drastic possible solution — flashing stock firmware. This procedure is only advisable for seasoned Android users as it involves doing advanced steps and can potentially cause more problems if not done properly. This can also be the only way out for bootloop cases that occured a user has tampered the software by rooting, installing apps from non-Play Store sources, or flashing. If you are a newbie to Android, we suggest that you skip this step unless you can accept the chance that your Note9 may be damaged permanently.

Keep in mind that Samsung will not entertain any repair request once they realize there’s obvious signs of software tampering.

If you want to give flashing a try though, use Google to find a good guide to help you do it.

Solution 5: Contact Samsung support

Some Galaxy devices in the past got stuck in bootloop after installing a system update or app. If this is what happened to you, we suggest that you call Samsung so you can allow them to fix your Note9.
