After flashing, reboot your device by:
Once it has rebooted, it is now time to flash the radio. Do this by using the following line:
./fastboot flash radio [radio_file].img
After this, reboot the device again.
Once these steps above are done, it is now time to flash the actual system. Enter the following line to the terminal or command prompt:
./fastboot -w update [image_file].zip
The device will reboot as it installs the new files. So do not panic.
Flashing and OTA image
This is the final step in updating your Android device. To do this, download the latest OTA images from Google and save it to the same Platform Tools folder.
Reboot you device. While booting, press the volume down button twice to select the Recovery Mode and press the power button to execute it. After this, hold the power button and press the volume up button to enter the Recovery Mode. Once in this done, you are now ready to copy the new OTA file. To do this, enter the following line to the terminal or command prompt:
./adb sideload [OTA_file].zip
Wait for the installation to finish. This will conclude the update process. You have successfully updated your device.
