HCU Unlocker

IMPORTANT: This is a paid tool which gives a limited timed license to use a properietary non open source tool. I cannot guarantee that this is safe or work for you but I can say that it has worked for me.

The above steps are based on the provided tutorial from HCU unlocker. If my steps are too confusing then following the official tutorial.

1. Download HCU Unlocker

2. Purchase a 72 hour license

Payment screen

  1. Purchase a DC-Phoenix + HCU timed license for €19.00 here.
  2. You will get a username and password pair which you can then use to login to the HCU unlocker.

3. Login to HCU unlocker

Login screen

  1. Login with your username and password pair. Once you start you will only have 72 hours to get read your code so make absolutely sure that you are prepared to go through with this.

4. Select CPU loader

CPU loader

  1. (Optional) Check in device manager if Huawei USB COM 1.0 is present before starting. If it isn’t activate your phone in testpoint mode again. You may need to do this multiple times.
  2. Select Fastboot/Xloader (Hisilicon only) while your Honor Play is in testpoint mode
    • Manufacture mode - COM ports doesn’t work for the Honor play since it uses the Kirin 970 and is using hardware testpoint mode.
  3. Select a CPU loader for the Kirin 970 from the menu. There are multiple options (5 for me) where only one of them will work.
  4. Click Read phone info. If it fails move onto the next option until it works.
    • Make sure that your phone is in hardware testpoint mode via device manager.
    • Make sure that you are using the correct driver (I had to use Driver 1 since Driver 2 did not work for me).

My results with CPU loaders

  • Honor Play COR-L29 9.1.0.399 (C636E3R1P12T8)
  • You might get different results to me.

5. Read bootloader unlock code

  1. Hopefully if it there is a working CPU loader you will get a success message on the right panel.
  2. Enable the checkbox Write bootloader code without changing any other fields.
  3. Click on Repair.
  4. Get the bootloader code from the phone information shown in the right hand panel.
    • Refer to the below snippet from my own read attempt as to what you should expect.
    • Refer to the tutorial linked at the head of this page for the official steps.
