How To Fix a Bricked Samsung Galaxy M51 (Stuck in Bootloop)

Follow this tutorial to learn how to unbrick your Samsung Galaxy M51. If you have accidentally bricked your Galaxy M51, do not worry. Most of the time you can easily fix a bricked phone. A device is considered bricked when it is stuck in a boot loop and cannot boot the OS. This is often called a soft brick and it happens for many reasons. Most of the time users fail to follow online tutorials properly, and as a result, end up installing incompatible software.

If for some reason your Samsung Galaxy M51 is also stuck in a boot loop and it refuses to boot up past the Samsung logo, it means that is soft bricked. This might have happened for a number of reasons. We cannot go into detail about all the reasons why a phone can get bricked, but below are the most popular reasons why.

Why your Galaxy M51 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.

If restarting your phone and wiping does not work, then flashing a stock firmware is the last resort.

You can flash stock firmware using Odin.
