If all files downoaded successfully and the checks read "OK", you can continue with the installation.
Enable developer mode
Your device needs to be in developer mode to continue with the installation. What operating system is the device running right now?
Go to the settings menu, scroll down and select "About phone".Scroll down to the bottom again, where you see "Build number."Tap it seven (7) times. After the third tap, you'll see a dialog that says you're four taps away from being a developer. Keep on tapping until you see a dialog saying "You're now a developer"Now go back to the Settings menu and find "developer settings" (sometimes called "developer options"), Tap that.Enable the "OEM unlock" and "USB debugging" options.Open System Settings, go to About this Phone, and then Developer Mode.The adb service will be enabled if 'developer mode' is selected. Note that you must have some sort of lock screen security enabled (pin or password), and 'Developer mode' will be greyed out if that's not the case.The 'Lock Security' menu there can be used to set a pin or password.Connect your device to your computer and run the following command to see if the adb connection works:
adb devices
You should see something like this:
List of devices attached
0123456789ABCDEF device
If your device does not show up, disconnect your device and plug it back in again, or run the following command and try again:
adb kill-server
Unlock the bootloader
First, you need to reboot your device to bootloader mode. Press and hold the volume up and power buttons until the phone reboots. Use the volume keys to select bootloader mode and confirm with the power button. Now, connect your phone to your computer and run the following commands to wipe the internal memory.
sudo fastboot oem unlock
sudo fastboot format cache
sudo fastboot reboot-bootloader
If you want to erase the data on the device, run these commands:
sudo fastboot format userdata
sudo fastboot format system
Installation
sudo fastboot flash recovery recovery.img
Now reboot the device to recovery mode. Press and hold the volume up and power buttons until the phone reboots. Use the volume keys to select recovery mode and confirm with the power button. Create a new text file called "commandfile" with the following content:
format system
load_keyring image-master.tar.xz image-master.tar.xz.asc
load_keyring image-signing.tar.xz image-signing.tar.xz.asc
mount system
