The procedures to unlock the bootloader on your Samsung Galaxy A51 handset are described in this guide. This offering from the South Korean Conglomerate quickly rose to the top of the charts. Its specifications sheet also drew everyone’s attention. The performance front is well managed, thanks to an underlying octa-core Exynos 9611 chipset coupled with up to 8GB of RAM and Mali-G72 as the GPU. Similarly, the quad rear camera, which was supplemented by a single selfie camera, took some decent photos.

It even features a 3.5mm headphone jack, which is now considered a rarity! However, due to the inclusion of the Exynos chipset, there were a few reservations regarding two separate features. The first is whether it will be able to compete in terms of performance with the Snapdragon chipset. I spoke with a few A51 device owners about it, and they were mostly satisfied with its daily use. Now, the second query was mostly associated with tech enthusiasts.

There’s a common misconception that custom development of Exynos chips isn’t as active as Snapdragon or MediaTek. Although to a certain extent true, this is not the case with this device. The device is a fairly active player in this space, with a plethora of tweaks already available. If you want to try them out, there is only one requirement: an unlocked bootloader. And in this guide, we’ll show you how. Here are the steps for unlocking the bootloader on your Samsung Galaxy A51 smartphone without further ado.

Benefits and Drawbacks of Unlocking the Galaxy A51’s Bootloader

Unlocking your device’s bootloader gives you access to a plethora of customization options. You could flash different Custom ROMs, install Custom Recovery (such as TWRP), experiment with a plethora of mods and hacks, and, most importantly, root your device. The latter could be done with or without TWRP (flashing Magisk ZIP with TWRP) (by patching and flashing the stock boot. img). After gaining administrative privileges, you can experiment with a plethora of Magisk Modules, Xposed Framework, and Substratum Themes, among other things.

They do, however, introduce a few uninvited risks. To begin with, it will set off your device’s Knox counter. This immediately renders your Samsung device’s warranty null and void. Your device will also be completely cleared of all data. Furthermore, all apps that rely on Knox will cease to function.

These include features such as Samsung Pay and Secure Folder. Similarly, apps like Google Pay and Pokeom Go may no longer work. Netlfix Widevine L1 Certification will also be downgraded to L3, preventing you from watching HD videos. With that said, if you’re ready to go, here’s how to unlock the bootloader on your Samsung Galaxy A 51.
