Display removal guide by ifixit https://www.ifixit.com/Guide/Huawei+MediaPad+M3+Motherboard+Replacement/127053#s247249

Testpoint for W09 variant is attached. Let me know if it works for DL09 also(it should).

Use heat and/or alcohol at top and bottom of display to remove.

Disconnect battery and display flex-cable from motherboard.

Press power button for three seconds to clear device.

Plug usb cable to tablet only.

Use sharp tweezers to short testpoint to heat-shield with qr-code(the closest one does not ground)

Plug usb into computer while keeping testpoint shorted.

As soon as you see or hear connection release short by simply removing tweezers.

You are now in Huawei USB COM 1.0 mode.

Complete IDT setup and flash .xml firmware from usb_upgrade folder.
