Bootloader Unlocking isn’t something that most of the users are interested in but it’s a necessary tool if you want to tweak your device with MODs or install a custom ROM with the latest Android version. OnePlus has always been a developer-friendly OEM as they release the sources on almost the same day as their mobile devices. The same is true for OnePlus 6T for which the sources were uploaded on Github on the release day of the device.
Few days in and developers have already built a working TWRP recovery and now MODs & tweaks have started pouring in on the XDA Forums. If you found some mods that you might wanna use on your OnePlus device but don’t know how to Unlock the bootloader of the device then you have come to the right place. So let’s get right into the prerequisites but before that a Disclaimer.
