The new Realme Android phones come with a locked bootloader. You can’t flash recoveries like TWRP or other .img files until you unlock the bootloader. But after unlocking the Android bootloader, you will be able to flash any recovery, modded image file, and even you can root the device. Realme released the official bootloader unlock guide on their forum. We will share the step-by-step guide. In this guide, we will show you How To Unlock Realme Phones Bootloader, the Official Method with the DeepTesting unlocking app, and the fastboot OEM code.

    At present Realme have stopped supporting the required tool. (Depp test or in-depth test depending on OS).
    There is no sign they will resume the service.
    So at present, you can unlock the bootloader with MTK client. But you CANNOT use fastboot.
    This means no rooting, etc…
    Which means no TWRP etc… (because the non-root method requires fastboot)
    So we’re stuck.
    Anyone have suggestions, please feel free to share them.
