HOW TO INSTALL TWRP RECOVERY ON HUAWEI G8

1. Download the TWRP custom recovery image file from here.
2. Install adb and fastboot on your computer and open the folder where you have adb when you’re finished.
3. Copy the TWRP Recovery file over to the same folder as your adb so they are both sitting in the same directory.
4. Hold the Shift key and right-click the mouse within the folder where it shows the white background and choose to open a new command window here from the menu.
5. Type the first command: adb reboot bootloader
6. The Huawei G8 smartphone will now boot in fastboot/bootloader mode; type the next command:  fastboot flash recovery twrp.img
7. The custom recovery is now fully installed on your Huawei G8 smartphone; type the next command: fastboot reboot

As soon as you type the ‘fastboot reboot’ command, hold the recovery mode hardware button combination for your Huawei G8 smartphone so it boots into the recovery mode during the first time boot. Sometimes the stock recovery can wipe the work you just did if you do not go directloy into the custom recovery. Once you are in the TWRP mode, you can reboot back in normal mode.
