Lenovo TB3-850M Unlock FRP by UMT.

I have a problem with unlocking the Lenovo TB-850 Tablet via UMT. This is exactly about the Ultimate Multi Tool - QcFire program. The program does not see the phone and keeps waiting:

Device : Lenovo Yoga Tab 3 8.0 (YT3-850M)
Operation : Read Information
Checking for existing devices...Not Found
Turn Off phone, hold Vol UP + Vol DOWN and insert USB cable.
Some phones may need Special Boot Cable or TestPoint for EDL mode.
SAMSUNG : Turn Off phone, hold EDL Cable Button and insert to phone and
press VOL DOWN + POWER on phone more than 3 times rapidly and then leave EDL Cable Button.

I used many cables, including the cable with the EDL button. The phone appears in the COM ports for a moment and then disappears. I have Win7 32 bit. I would like to ask for help what I am doing wrong.

Finally, I managed to unlock the tablet myself. You had to use Ultimate Multi Tool - MTK v5.1
Select "By Platform" and select the MT6735M model.
