If you have bricked your Samsung Galaxy M21 2021 Edition and it is stuck in a boot loop, you have come to the right place. Follow this article to learn how to unbrick your phone. When a phone is bricked, it usually cannot get past the Samsung boot animation logo. This is called a boot loop, which means the phone cannot load the OS firmware. Most of the time users fail to follow online tutorials properly, and as a result, end up installing incompatible software, which bricks the phone, in this case, the Galaxy M21 2021 Edition.
If for some reason your Samsung Galaxy M21 2021 Edition is also stuck in a boot loop and it refuses to boot up past the Samsung logo, it means that is soft-bricked. There are many reasons for this.
Why your Galaxy M21 2021 Edition is bricked
- Flashing the wrong firmware: Each firmware available online is created and designed for a specific phone model. The problem with Samsung is that it creates multiple variants of the same phone. For example, a phone in one country has Samsung’s own Exynos chipset, while the same phone version might have the Snapdragon chipset in another country. As a result, it is always recommended to carefully check the model number of the firmware before flashing anything. If you flash a firmware designed for another phone model, your phone will get stuck in a boot loop.
- Flashing the wrong custom ROM and kernel: The same thing applies to other files that you might flash on your phone. If you download and flash a wrong custom ROM, kernel, or any other files that are not designed for your phone, they will brick your phone.
- Failing to wipe data & cache: Some tutorials and procedures requires the user to wipe data and perform a factory reset. For example, installing a new ROM that has a different Android version to the one your phone currently has, requires a full data factory reset. If you fail to wipe data, the phone will fail to boot up.
