DTPro I can't put my Huawei P50 Pro model phone into EDL mode

[tdl55]

Hello. I want to change the IMEI of my Huawei P50 Pro device. I installed the necessary drivers but I could not put the device in EDL mode. When I apply the method in the link below, the phone restarts but I cannot see the Quallcomm label in the device manager.

I also bought a deepfash cable from China for this. However, I still cannot connect to edl mode. I ask for your help.

On Devices with the latest Revision Patch! It is not possible to enter Edl Mode from adb or Fastboot!
- Requires Testpoint [physical]

En son Revizyon Yaması olan cihazlarda! Adb veya Fastboot'tan Edl Moduna girmek mümkün değildir!
- Testpoint gerektirir [ fiziksel ]

Thank you
