How to Unlock the Bootloader on Your Pixel 4 «Android :: Gadget Hacks



Pixel 4 is one of the most talked-about phones of 2019, and there are many things to do, especially in the world of rooting and modding. As with previous pixel generations, unlocking the bootloader is the gateway to unlock the true potential of your device. This can also make room for TWRP, Magisk, custom ROMs and many other device-specific mods.

The bootloader is software that tells your phone what it needs or needs to be restarted each time it is turned on. By default, the bootloader only allows official firmware from first-party vendors to be installed and run natively on the device. Unlocking the bootloader allows you to use third-party firmware on your device, allowing for modification.
