Here is a complete walk-through and guide on how to unlock bootloader on OnePlus phones. Whether you are looking to install a custom ROM or trying to root your device, bootloader unlock is a prerequisite to all mods. More, it also enables manual flashing of official firmware along with Open Beta builds. A must-do, in our opinion, for all OnePlus owners; read the guide ahead to learn about the official unlock bootloader process.

Being a enthusiast brand, OnePlus officially supports bootloader unlock on all its devices. Due to security concerns and a vast number of users who wont be modifying the system, the brand doesn’t ship each phone unlocked from the factory. Rather, it allows an official unlock built-in that doesn’t require any sort of wait. The procedure is a bit technical but as we have split it into simpler steps, readers can easily unlock bootloader on OnePlus phones.

Moreover, the T-Mobile version of the OnePlus phone comes loaded with some of their own carrier apps (i.e. bloatware). The rest of the device is the same.
