Upgrading Instructions

1. Requirements

  1. Mate 9 Pro (LON-L29) variant already on C185 firmware
  2. Windows PC with ADB/Fastboot drivers
  3. A USB cable

2. Procedure

Step 1. Create a new folder named “HWOTA” in external microSD card of your phone.

Step 2. Download the firmware zip files (update.zip, cust and public package) provided above, rename them as mentioned and then copy them to the new HWOTA folder in the SD card.

Step 3. Disconnect the USB cable and power your phone off. After that reboot into the bootloader (fastboot) mode by reinserting the USB cable while simultaneously holding the Volume down key.

Step 4. Download the Mate 9 Pro updater tool from here and extract the HWOTA folder from the zip package to your PC.

Step 5. Open the extracted HWOTA folder and run the update.bat file as administrator.

Step 6. The updater window will ask you to reboot your phone into fastboot mode – as you already did that in step 3, press Enter to proceed.

Step 7. After replacing the recovery the updater tool will tell you to boot into recovery – to do that, disconnect the USB cable and press & hold the Power key to turn it off. Next, reboot into TWRP mode by holding Volume up + Power 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 8. In update source selection, type in 1 and press Enter. For update type, again type 1 and press the Enter button twice.

Step 9. In a few seconds, your device will automatically reboot and begin update installation on the patched stock recovery. You can now safely disconnect the USB cable from the device.
