Step 2: Connect your device to the computer via the USB cable.
Important: Now, as mentioned in “Before you Begin” section, we are assuming that you have set up ADB and installed ADB drivers for Nexus 4. That’s a must. To confirm if you have ADB successfully set up, launch Command Prompt and execute the command: adb devices
It will return device serial number which means that ADB drivers for your device are installed on the PC and it’s working fine. Let’s move on then.
Step 3: Boot Nexus 4 in custom recovery mode.
- Execute this command: adb reboot bootloader
- Once in bootloader mode, use volume keys to highlight the “Recovery” option
- Use Power button to select the “Recovery”. You will see Android logo with exclamation mark on your device.
- Press Volume up + Power buttons at the same time to enter recovery mode
Step 4: Now execute following command in Command Prompt:
adb sideload [file.zip]
[file.zip] = path and name of the zip file that you downloaded in step 1 above.
This will now flash the zip file to your device. You’ve got to wait till the process is complete.
Step 5: Once the flashing process is complete, reboot your device.
You should now have rooted Android 4.3 on Nexus 4 installed successfully. Enjoy!
