Nevertheless, you don’t have to be worried when dealing with this kind of problem.
In today’s article, we’re going to be tackling the issue of boot loop. We’ll teach you how you can fix it all by yourself on your Galaxy S9. However, you have to know that troubleshooting is pretty safe, but sometimes they can go wrong. So whatever you do will be at your own risk, if you wish to continue, read follow these instructions on how to troubleshoot your Samsung Galaxy S9 whenever you stuck on activation boot loot.

First Step: Safe Mode

Booting your phone into a Safe Mode will allow you to disable all the third-party apps and services temporarily. If third-party apps are the cause of the boot loop, you’ll be able to confirm after all, since your phone is in Safe Mode they won’t be running on your phone. This case is usually typical, and the method is the easiest out of the three.

Accessing the Safe Mode on Galaxy S9

Press and hold the Power button
Let go when Samsung S9 displays a message
Immediately press and hold the Volume Down button
Let go of the key when the phone finishes booting; Safe Mode will show at the bottom left corner of your screen

Troubleshooting your Galaxy S9 in Safe Mode

Start monitoring what happens to your phone, if it works well, and no longer show the problem, then this means your third-party app is the root of the problem. You should know that you can still open the third-party apps despite being in Safe Mode. Start the troubleshooting by testing all the third party apps one at a time.
If you have few apps, you can perform this function manually beginning with the most recent apps. But if you want too many apps, you can opt for resetting your phone. However, before you do this, ensure you backup all your data. Follow this step if you don’t know how to do this:

Open the App menu
Click on Settings
Go to Backup and Reset
Click on Factory Data Reset
Select Reset Device
If required, enter your unlock password
Hit Continue
Tap on the Delete button for reset confirmation

Move to the next method if your device didn’t boot while in Safe Mode

Second Step: Cache Partition, Recovery Mode, and System Cache

The Recovery Mode is a useful function for troubleshooting any firmware problem. The mode allows you to power up all the elements of your phone; it is a medium to see if the entire component works as they should. Also, Recovery Mode let you access a different range of services relating to firmware and system.
The aim is to make your phone boot into Recovery Mode, and from this point, you can remove all the system cache data. Android created the data automatically; this means they’ll always come back after deleting them.

You have Two Alternatives if you cannot Boot into Recovery Mode

Manually flash your stock firmware; you can also install the firmware from scratch.
Seek the assistance of a technician to help with the troubleshooting

Note, if you don’t know what it means to “Flash the Stock Firmware,” or if you have never successfully performed this action, we’ll advise that you couldn’t do it. The procedure can void your warranty, and it is possible that it may not fix the bootloop issue on your phone.
However, if you can perform this procedure, there is a chance you can fix the issue with this process. It doesn’t matter the number or kind of corrupt files you have; it could remove them.

Third Step 3: Master Reset and Recovery Mode

We have to emphasize this; you can’t boot into Recovery Mode, you surely can’t perform a Master Reset, and your journey ends here. However, if you boot successfully into Recovery Mode and still couldn’t fix the issue, you can try the Master Rest, and this is the ultimate solution.
How to perform the reset is close to the Factory Reset. However the difference is that you won’t just delete all the data, but you will also have to reformat the data partition. The procedure will make your Samsung Galaxy S9 look like a brand new smartphone. The configuration will be like the one you took right out of the box.
Formatting and deleting your phone is the best way you solve lots of other issues. Follow this process:
