Unlock - Bootloader - LG Nexus 4

Warning : The methods and procedures given here are one and only for LG Nexus 4 device. So, don’t try it on other device. It is considered to be risky. Best Android Blog would not be held responsible/liable for anything that happens wrong in your device.

Instructions to Unlock Bootloader in LG Nexus 4:

1. Before start to proceed the first and foremost thing you have to do is backup of your internal datas.

2. Next download and install the Android SDK from here. This will install the necessary drivers for the phone on your computer.(The drivers for your phone can be installed manually by other methods too, they are mandatory) For the fastboot driver to install (and for fastboot commands to work), your device must be booted in fastboot mode.

3. Then download the fastboot from here. It will be used for unlocking the Bootloader.

4. Next extract the fastboot.zip file on your computer to get a folder named fastboot with four files inside it. To keep things easy, extract the Fastboot folder to your C:drive.

5. Turn off your Nexus 4. Then, boot it into the fastboot mode by holding down the volume down button and power button together till the screen turns on and shows “Start” written in big green letters.

6. After that connect your LG Nexus 4 device to the computer with the USB cable, then wait for Windows to finish installing the drivers (drivers will be installed only the first time).

TIP : For reliability, ensure that you use a USB port at the back if you are using a desktop computer, as the front panel ports can be loose and cause problems.

7. Click on Start menu » All Programs » Accessories » right-click on Command Prompt and click on Run as administrator. If you are using Windows 8, this can be done by right-clicking on the extreme bottom left corner of the taskbar, then selecting “Command Prompt (admin)”

8. Now, perform the following steps in the command prompt to unlock the bootloader.

8.1 Navigate to the Fastboot folder which you obtained by using the above mentioned step. For example, if the Fastboot folder is in drive C on your computer, enter cd C:\Fastboot in command prompt (and press Enter) to navigate to the folder.

8.2 Then, enter fastboot devices. If your Nexus 4 has been detected properly, you will see a device ID show up in command prompt. If nothing comes up, make sure you have installed the drivers.

8.3 Finally, to unlock the bootloader, enter fastboot oem unlock in command prompt. You will get a prompt on the phone asking whether you want to unlock the bootloader. Just select Yes.

9. Your phone will then reboot, and once it starts up, you can set up your phone.

10. To relock the bootloader, simply follow the entire procedure again from step 5 to 8, but in step 8.3, enter fastboot oem lock. This will re-lock the bootloader.

That’s it! The bootloader on your Nexus 4 is now unlocked, and you can start installing custom ROM and other modifications to the phone. Enjoy!!!!!
