I have Y9 prime 2019 STK-L21 Android version 12 EMUI version 12. I want Write CERT. But it's testpoints is disabled. first I check that it's usb connection is right. when I turn on the device it connected transfer files, shows hisuit & manufacture ports on device manager means thats it's usb connection is okay. I searched & find that emui version 12 disable the testpoints so I make the harmony cable it connected & show ports on Mobile power on condition. but when I turn off the phone and connect the cable & testpoint it doesn't shows anything. nothing no port. I thought may be modified cable is not working anymore. so I bought harmony cable from market & repeat the process. but from that cable it also shows nothing.I downgrade EMUI version 12 to 10 but testpoint with modified cable doesn't work. so that's why I try to find this solution on youtube, forums & telegram but nothing find anything worthy.

Kindly anyone have the solution tell me.
thanks

Hello

When you connect device with cable and TP battery should be connected.

Was battery connected?

Also, try to re-install USB COM 1 drivers
