Step 1. Create a new folder “HWOTA” in the external microSD card of your device.
Step 2. Download the firmware update files provided above and copy them to the new HWOTA folder in the SD card.
Step 3. Disconnect the USB cable and power off your device. After that, reboot into fastboot mode by reinserting the USB cable while holding the Volume down button.
Step 4. On your computer, download the Mate 9 updater tool (check the link in prerequisites) and extract the HWOTA folder from the zip file.
Step 5. Open the HWOTA folder on your PC and execute the update.bat file as administrator.
Step 6. A command window that opens up will ask you to reboot the phone into fastboot mode – as you’ve already done that, hit the Enter button to proceed.
Step 7. When the tool replaces and installs TWRP recovery, unplug the USB cable and hold the Power key to turn off. Then reboot into TWRP mode by holding Volume up + Power keys simultaneously for a few seconds. Once you’re in TWRP mode, plug in the USB cable again, wait for a few seconds and then press the Enter key on your computer twice.
Step 8. When the tool asks the update source, type “1” (without quotes) and press Enter. Next, in update type selection, again type in 1 and press the Enter button twice.
Step 9. In a couple of seconds, your device will reboot and start installing the update. You can now safely unplug the USB cable.
