How to Unlock Bootloader of your OnePlus 3T

If you are not familiar with the world of Android hacking and rooting, then there are many terms that you might not know. However, you must change that in order to get the best from your OnePlus 3T and unlocking the bootloader is a necessary requirement.

I am saying that as long as unlocking the bootloader is the first step to flash a Custom recovery and install a ROM, to root your OnePlus 3T and discover a world of possibilities. To be more precise, if you want root, you’d be in the position to flash the Custom ROM post-root, and if you want to install a Custom ROM, then you’d need to have your stock bootloader unlocked.

Every Android phone has a bootloader that instructs the operating system kernel to boot normally. So, in other words, the bootloader is a code that executes while the device is booting and which powers the operating system for the initial run.

However, you must keep in mind the fact that the Android OS is an open source OS and is available on a variety of different hardware, every manufacturer has their own version of bootloader specific for the hardware present in its environment. That is why things might a little different and you might need some guidance.

In order to get ready for such a procedure, you have to take a backup of your data. Unlocking the bootloader will wipe all your device’s data, so you have no other choice but to do that.

Even more, you have to keep the battery percentage above 60% to prevent any potential shut-down and yes, unlocking the bootloader on OnePlus 3T will void your phone’s warranty. I am not responsible for any damage to your phone. Please follow the steps carefully and proceed at your own risk.
