⭐️ HarmonyOS Support on Huawei (Kirin CPUs) Phones ⭐️ First in the World ⭐️ - GSM-Forum

**Chimera Tool** · 10-09-2021, 00:55

Factory/bootrom mode (HUAWEI USB COM 1.0) service functions are now available on Huawei phones with HarmonyOS!

Here are some of our most used factory/bootrom mode functions:

FRP and Huawei ID Remove
Modify OEMInfo (Vendor/Country, Disable FW version check, ...)
Load Factory Fastboot (partially supported; updates in progress)
And many more...

Supported CPUs: Kirin 710/710A/710F, 810/820, 980/985, 990/990 5G

The Problem

Due to some changes done by Huawei, phones that are updated to HarmonyOS, would not present the Huawei USB COM 1.0 serial port after test pointing. Without the Huawei USB COM 1.0 serial port Chimera cannot communicate to these devices in factory/bootrom mode.

The Solution

You need to use a modified USB cable, we call it the "Harmony TP Cable". If this cable is used, Huawei USB COM 1.0 serial port is available and all Chimera factory/bootrom mode service functions will work on HarmonyOS models.

Harmony TP Cable, How-to

What you need:

1 pc. 150 Ohm (150 Ω) resistor
1 pc. 270 Ohm (270 Ω) resistor
1 pc. 1.5 kiloohm (1.5 kΩ) resistor
and 1 pc. standard USB cable

Here is how-to make the cable:

Important Notes

You still have to test point (this cable only works if the test pointing is done)
Make sure that you always connect the cable to the phone first
Make sure, when asked to disconnect you always disconnect the cable from the computer first
You have to see the Huawei USB COM 1.0 serial port in Windows Device Manager. If you cannot see it, most probably the modified cable is wrong.

FAQ

Why do I see unknown device in Windows Device Manager?
Most probably you connected the cable to your computer first. Please make sure that you connect the cable to the phone first.

I disconnected the cable but I can still see the phone connected, why?
Most probably you disconnected the cable from the phone first, and not the computer. Please make sure that you always disconnect the cable from the computer first.
