Harmony TP V2.0 Cable Entering Huawei USB COM 1.0 for Harmony OS or Chimera Pro Tool Dongle

The Problem:

• Due to some changes done for Huawei, phones

• that are updated to HarmonyOS, would not present the For HUAWEI USB COM serial

• port after test pointing. Without the For HUAWEI USB COM serial port Chimera

• cannot communicate to these devices in factory/Boot ROM mode

The Solution:

• You need to use a modified USB cable, we call it the “Harmony TP Cable”

• If this cable is used, for Huawei USB COM serial port is available and all Chimera factory/Boot ROM mode service functions will work on Harmony OS models

Package includes:

• 1 x Harmony TP V2.0 Cable

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 For HUAWEI USB COM serial port in Windows Device Manager. If you cannot see it, most probably the modified cable is wrong
