How to Update

- Windows PC with ADB/Fastboot drivers
- Full backup of existing data and apps
- A USB cable
Step 1. Connect your phone to your computer and create a new folder named “HWOTA” (without quotes) in the external microSD card.
Step 2. Download the firmware files provided above, rename them and then copy them to the new HWOTA folder in the SD card.
Step 3. Unplug the USB cable and turn off your phone. Reboot into fastboot/bootloader mode by reinserting the USB cable while holding the Volume down key at the same time.
Step 4. On your computer, download the Mate 9 updater tool (Mega Link) and extract the HWOTA folder from it to your PC.
Step 5. Open the HWOTA folder on your desktop and execute the update.bat file as administrator.
Step 6. A command window will open up and ask you to reboot your phone 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 mode.
To do that, 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 to select 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 installing the update.
