Requirements: You’ll need to have ADB/Fastboot with necessary USB drivers installed on your PC. Make sure your device is already running a C432 (Europe) based firmware.
Step 1. Connect your phone to your PC via a USB cable and create a new folder HWOTA in its external microSD card.
Step 2. Download the aforementioned firmware zip files, rename them and then transfer them over to the new HWOTA folder you created in the microSD card.
Step 3. Unplug the USB cable and turn your phone off. Boot into fastboot/bootloader by reinserting the USB cable while holding the Volume down key at the same time.
Step 4. On your PC, download the Mate 9 updater tool (use this link) and extract the HWOTA folder from the zip file to your desktop.
Step 5. Open the extracted HWOTA folder on your desktop and open the ‘update.bat’ file as administrator.
Step 6. A command window will pop up and ask you to restart your device into fastboot mode – you’ve already done that so press Enter to proceed.
Step 7. The tool will replace your phone’s recovery and then ask you to boot into TWRP recovery.
To do that just unplug the USB cable and hold the power key to turn your phone off. After that, press and hold Volume up + Power simultaneously for a couple of seconds to enter TWRP mode.
Step 8. Once you’re in TWRP, reinsert the USB cable, wait for a couple of seconds and press the Enter key on your computer twice.
Step 9. When asked to select the update source, type 1 and press the Enter key. Next, in update type selection, again type 1 and press Enter twice.
In a few seconds, your device will automatically reboot into recovery and install the new update.
