Can some one else confirm if Huawei is closing TP again even with Harmony cable from this version JNY-L01 12.0.0.268(C16E3R2P2)‬?
I have one with test point 100% i checked and compare with an other board.
Fastboot connnect ,usb connect in normal mode but with test point no communication with PC with normal or Harmony cable i have,3 harmony cables all still work on older version but not working on this version of P40 lite(JNY-L01 12.0.0.268(C16E3R2P2)‬ ?

Hello

Try to re-install COM 1 drivers.

Also, make sure that TP is correct.

As i said dear i have 3boards all 2 old boards are still connecting with all my PC with
harmony cable except this new version one and since i have 3board i did check with multimeter for comparison with other board test point is ok and measures 318 Khom to ground just like the other 2boards.
So i am almost 100% sure that TP is ok and clean and my Harmony cables are 100% working
