Follow this guide to learn how to unlock the bootloader on your OPPO A74 (5G). Most modern Android phones come with locked bootloaders, which make it difficult to install custom ROMs, mods, kernels, or even enable root with Magisk. Thankfully, the OPPO A74 (5G) bootloader can be unlocked in a few simple steps.
A locked bootloader is the barrier that prohibits users to modify the software of their devices. Luckily, the bootloader on the OPPO A74 (5G) can be easily unlocked. Once that has been done, users can then go ahead and root the phone, install Magisk, and install custom ROMs.
How To Unlock OPPO A74 (5G) Bootloader
A bootloader is an important piece of code that runs before the operating system. It gives instructions to the phone on how to boot up and how to find the system kernel. In other words, your phone, and in this case, the OPPO A74 (5G), cannot boot up without a bootloader.
For security purposes, OEMs lock the bootloader beforehand. This makes the device more secure and less susceptible to manipulation. However, this also makes it impossible for consumers to flash ROMs and custom mods. As a result, the bootloader needs to be unlocked to make any manipulations to the firmware.
