What is Android Bootloader?

Do you know that Bootloader is the first thing that runs when you boot up your Android-powered device? Well, yes and it is just like a BIOS to Windows.

Every pro-Android user wants root access on their Smartphone. Well, it is mandatory only for those users who love to modify & add betterment to their mobile experiences. However, to get superuser access to root your device, it’s the work of bootloader.

How To Unlock Android Bootloader?

Here is the way to unlock the bootloader on any smartphone. However, you need to follow the below steps carefully and make sure you don’t touch anything we haven’t said. Altering sensitive settings may damage your phone, and it’s performance. So, stick to the steps we have provided down below.

Firstly Backup Important Data

Unlocking the bootloader will sweep all of the data of Android. So it is important to back up any photos, videos, app data or any other files on your device. I would recommend you to use Titanium Backup (available on play store). Also, you need to Backup all your phone data before continuing to the next step.

Download KingoRoot(Recommended)

KingoRoot is the easiest root tool that works for free. It is an alternative to the Android SDK and USB driver, which improves feasibility. Furthermore, KingoRoot includes the Android SDK and will download the USB driver for your device automatically once connected to the PC. Here are the steps you need to follow:

  • Download & Install KingoRoot to your PC. You can follow this link to download KingRoot for your PC directly.
  • Connect your smartphone to your PC with the help of a USB cable.
  • Enable USB debugging from your Settings > About phone > Build Number (Tap 7 times to enable the option)
  • “You are now a developer Message” will pop up now on your Android screen.
  • Go to Settings > Developer Option > USB Debugging (tap on the checkbox to proceed)

Launch the App

Once you launch the KingoRoot on your pc, the PC will download the USB driver of your device automatically. Next, you need to visit KingoRoot, Go to Installed Directory > KingoRoot > tools > KingoRoot.exe

Open cmd (as given below)

Start by inputting the letters “cmd” in the “address bar”, and hit Enter.

Open cmd

Codes in Command prompt: adb devices

Now the command prompt window will pop-up as shown below. If it shows serial number, the PC has recognized your device, and you can continue with the process. Otherwise, do check that you’ve performed the above steps correctly.

Codes in Command prompt: adb devices

Get The Unlock Key

Visit your manufacturer’s bootloader unlocking page, create an account. The device will boot into fastboot mode. Always keep the connection enabled so that the process doesn’t fail. Also, search on google “Unlock “ Your Phone Brand And Model” Bootloader to find the unlocking page.

Get The Unlock Key

Now it’s time to retrieve the unlock key as provided by your Android device manufacturer.

For example:

  • (For Motorola) fastboot_oem get_unlock_data
  • (Also, for HTC) fastboot OEM get_identifier_token

Now simply select the token, that is thrown out by the Command Prompt window.

Next, you need to copy the token and paste it into the application box. (use the code without any spaces anywhere)

Now simply select the token

Submit the form and wait for an email with a key, once you receive the key proceed to the below steps.

Unlock the bootloader of your Android device

Run the below command

>> All manufacturers have different code. For Example

  • (For Nexus Users) fastboot OEM unlock / fastboot flashing unlock
  • (And For Motorola Users) fastboot OEM unlock (UNIQUE_KEY from your email)
  • (Also For HTC Users) fastboot OEM unlocktoken (Unlock_code.bin file from email)

>> Use the “Volume” keys to confirm whether you are sure about unlocking the bootloader.

>> Also, you can reboot your Android device by running command fastboot reboot or using “Volume” keys for the reboot.

So, now your device will show a message at boot stating that your bootloader is unlocked. Also, with an unlocked bootloader, you will be allowed to root your Android, flash a custom recovery or install a custom ROM.
