How to Update
Compatibility: This update will only work on the Asian Mate 9 Pro variant carrying model number LON-L29.
Step 1. For this procedure, you’ll need a Windows PC with ADB/Fastboot drivers and a USB cable.
Step 2. Plug your phone into your computer via USB and create a new folder “HWOTA” in external microSD card.
Step 3. Download the firmware files (update.zip, cust and public package) 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 device off. Then reboot into the bootloader (fastboot) 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 (click here) and extract the HWOTA folder from the zip package 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 your phone into fastboot mode – as you’ve already done that, you can press Enter to proceed.
Step 8. After replacing the TWRP recovery the updater tool will tell you to boot into recovery – disconnect 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’ve entered TWRP, reconnect the USB cable, wait for a few seconds and then press the Enter key on your computer twice.
Step 9. In 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. You can now safely disconnect the USB cable and let the installation proceed.
