How to Unlock Bootloader of OnePlus 3

Do you want to root OnePlus 3? Do you want to flash custom ROM on OnePlus 3? If yes, then you need to unlock bootloader of OnePlus 3 first. There’s no doubt OnePlus 3 was the most amazing smartphone we have seen last year. This flagship phone had many breathtaking specs and features which made many Android users go crazy.

Some of these include 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, 16MP rear camera and 8MP front camera. Moreover, it runs on the Android 6.0 Marshmallow operating system.

If you are an Android geek like me, who is never satisfied with the specs and always wants something more to try on their phones, then you would want to root or install custom firmware on it. But before rooting or flashing any unofficial custom ROM you need to unlock bootloader of OnePlus 3. After that, you can not only gain root access but also implement various operations.

You can either install custom firmware, or 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. 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 in unwanted outcomes and bricked phones as well. Hence it is always necessary to unlock the bootloader before proceeding to any flashing processes. Here, we’ll see how to unlock bootloader of OnePlus 3 smartphone.
