Qualcomm MSM 8926 (SnapDragon 400) Need Help

[Formingus]

I Have ZTE Blade Apex2 with QC MSM8926 SD400
ZTE Blade Apex2 - Specifications

I need to factory reset but phone will not be recognized in EDL Mode

With Vol Down plus UP Pressed it will enter in DFU Mode aka ZTE Handset Diagnostic.

Forced to install Emergency Drivers , drivers installed as Emergency but software will not detect it.

I Use EDL Boot Cable too Same thing.

Phone condition :

Boot OK , when starting up xxxxx.com.process.stoped.
Factory Reset and Clear Cache from recovery will not Help

Any Idea or key combination to EDL Mode of This model. Thanks

Open the phone ... take a picture of mainboard, post here ...
It's usually accessible after taking off the back cover...

I'm vote for 2x3 point group under metal cover, up from sim reader.
100-500 Ohm resistor and between horizontal line, battery reset required between every try.
Then insert cable in device, when points shorted.

I agree with JayDi on that, it's usually close to CPU/eMMC,
but as i saw on huawei y530, it may be near usb socket.
so ... start connecting two by two, and after connect insert usb cable,
it should appear as emergency downloader port.

i attached picture with possible points location ...
(and possible "best luck" point)

Find eMMC VCC or DAT0 pin and short via resistor ( 100-500 ohm ) to ground, connect cable.
Or find TP points. They are marked as DLOAD or similar.
