Do you want to root the Android smartphone or tablet? Do you want to install TWRP recovery and flash custom ROMs? If yes, then you are in the right place. In this tutorial, we’ll discuss some easy steps for unlocking the bootloader of any Android phone. Before you install TWRP recovery or flash custom ROMs, you will have to unlock the bootloader of your Android.

What is Bootloader?

The bootloader is a code that is executed before any Operating System starts. Every Android phone has a bootloader that instructs the OS kernel to boot normally. Since Android OS is an open-source OS, every manufacturer has its own bootloader version.

Why is Bootloader locked?

It is not possible to install TWRP recovery or flash custom ROMs on a locked bootloader. Forced attempts to unlock the bootloader can void the warranty and brick the device. Hence, manufacturers usually lock the bootloader to make the users stick to their official Android OS.

Why unlock Bootloader on Android?

If you want to root, flash a custom recovery like CWM/ TWRP, or flash custom ROMs, then you need to have your bootloader unlocked. That means unlocking the bootloader allows you to gain root access, flash unofficial custom recoveries, third-party custom ROMs, take Nandroid backup and restore, increase internal memory, remove bloatware, and much more.

Phones like Motorola, Sony, LG, HTC, Xiaomi, and Huawei use a unique code through their website to unlock bootloaders. Samsung phones (Exynos models) that can be rooted have unlocked bootloaders. Whereas the new Snapdragon models of Galaxy S9, S9 Plus, S8, S8 Plus, S7, S7 Edge, Note 8, etc. all have locked bootloaders.

Moreover, the bootloader of Google Nexus or Pixel devices like Pixel 2 XL, Pixel 2, Pixel XL, Nexus 6, Nexus 6P, etc., can be easily unlocked using this guide. Also, the bootloaders of all OnePlus devices, including the OnePlus 6, OnePlus 5/5T, OnePlus 3/3T, etc., can be unlocked. If you’re unsure whether your device’s bootloader can be unlocked, you can still refer to this tutorial. It’s great if it passes. If it fails, no damage will be done.

  • Go to Settings and enable USB debugging mode on your device.

  • Using a standard USB cable, connect your Android device to a PC.
  • Furthermore, ensure that Mobile USB drivers are installed on your PC.
  • Go to the location where you’ve installed ADB and Fastboot drivers. (For example, C:\Program Files\Minimal ADB and Fastboot folder).
  • Then by holding the shift button of your keyboard, right-click on space.
  • From the list, choose the Open command window here option. This will launch the command window.

  4. After doing the “fastboot devices” step it doesn’t return anything. Then when I run the fastboot oem unlock/fastboot flashing unlock command it says “waiting for device.” What should I do?

    • I did face that problem and I just close the cmd window. Download the USB Drivers for the hp model. As for me, I download Google Driver and encounter waiting for device. So I download vivo USB Drivers for V15 Pro and it works BUT cannot unlock the bootloader. So sad…

  5. on a realme 7. I followed the steps but when I enter the adb reboot bootloader command all the phone does is a normal restart but it does not open in fast boot mode. I tried putting it in fastboot mode myself but that did not work. The device is recogniced. Maybe perhaps this method doesnt work on a Realme 7.
