How to Unlock Bootloader of OnePlus 3

There’s no doubt OnePlus 3 was the most amazing smartphone we have seen last year. This flasgship phone had many breath taking specs and features which made many Android users go crazy. Some of which includes 5.5 inches Optic AMOLED capacitive touchscreen, 64 GB internal memory, 6 GB RAM, Qualcomm MSM8996 Snapdragon 820 Quad-core processor, Li-Ion 3000 mAh battery, 16 megapixel primary camera and 8 megapixel front camera. It came with in build Android 6.0.1 Marshmallow OS.

If you are an Android geek like me, who is never satisfied with the specs and always want something more to try on their phones, then you would definitely want to root or install custom firmware on it. But before rooting or flashing any unofficial custom ROM you need to unlock bootloader of your smartphone. By unlocking bootloader you can not only gain root access but also install custom firmwares, flash modified system, kernel, increase internal memory, flash custom recoveries, .img files and much more.

Whenever you purchase a brand new smartphone, it comes with a locked bootloader. Basically it is locked because the manufacturer of that specific device wants you to stick to their self designed Android OS version. And if you even try to cross over those restrictions put forth by the manufacturer and root or install custom firmware without unlocking the bootloader, it will only result into unwanted outcomes and bricked phones as well. Hence it is always necessary to unlock the bootloader of your phone before proceeding to any flashing processes. Today in this step by step guide we’ll see how to unlock bootloader of OnePlus 3 smartphone. Actually it is the most simplest and easiest method for unlocking bootloader.
