Lenovo TB3-850M Unlock FRP by UMT.

[pomocrtv]

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.

Program can not see it until it is detected in Device Manager.

Please check Device Manager if 9008 Port appears there when you connect phone and it has drivers installed.

After connecting the phone with the VOL+ and VOL- keys pressed, a device like the one in the picture appears for a few seconds. I installed the drivers and they seem to be good

You are trying to connect MediaTek device with QcFire which supports Qualcomm devices.

You should try UltimateMTK2 v1.2 for MediaTek Devices.

I installed the program. I select the unlock option and the phone already communicates with the program. It didn't unlock the tablet and it seems to freeze. I can't run it (it starts only by pressing VOL+ and PWR).

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.
