How to Update
Step 1. Before installing this update, you’ll need to make sure you have ADB/Fastboot drivers on your PC, a USB cable and the MHA-L29 variant of Mate 9.
Step 2. Connect your phone to your computer and create a new folder named “HWOTA” in its external microSD card.
Step 3. Download the firmware files using the links provided above, rename them and then copy them to the new HWOTA folder in the SD card.
Step 4. Unplug the USB cable and power your phone off. Then reboot into fastboot/bootloader mode by reinserting the USB cable while holding the Volume down key at the same time.
Step 5. On your computer, download the Mate 9 updater tool and extract the HWOTA folder from it to your PC.
Step 6. Open the extracted HWOTA folder and execute the update.bat file as administrator.
Step 7. The tool will ask you to reboot the phone into fastboot mode – you’ve already done that so press Enter to proceed.
Step 8. After replacing the TWRP recovery the tool will tell you to boot into recovery – simply unplug the USB cable and press & hold the Power key to turn off. Then reboot into TWRP mode by holding Volume up + Power simultaneously for a couple of seconds.
Once you’re in TWRP, reconnect the USB cable, wait for a few seconds and then press the Enter key on your computer twice.
Step 9. When you’re asked the update source, type 1 and press Enter. Next, for update type selection, again type 1 and press the Enter button twice.
Step 10. In a few seconds, your device will automatically restart and begin update installation. At this stage, you can unplug the USB cable.
