Cmd Timeout Error Easy Jtag

Hi
I bought an z3x easy-jtag recently.
The box arrived this week and after I installed it, I tried to read eMMC with it but unsuccessfully.
So now I'm here to ask official developers any help.
To be easier to understand my problem by the support people and by anyone who's facing the same problems I'll try to simplify everything, explain my test conditions and give you images of a log of a phone that I've tried to read. Notice: the phone was fully working before trying to read its eMMC (and is still working, I supose...)
Here we go.

************************************************** *****
All of the above is a test condition to show to official supporters an example o my test conditions.
Now I'll report all that I have already tried to not let people make me waste my time and their with tips and tricks that I could have already tried:
eMMC reading:
I tried to read eMMC of 1 faulty (not booting) gt-i9205 Galaxy Mega
I tried to read eMMC of 1 faulty (not booting) gt-i9505 Galaxy S4
I tried to read eMMC of 1 great condition' gt-i9505 Galaxy S4
----------With Adapter------------
Using th Red Adapter that arrived inside the box' package that I bought from GSMServer, using the adpater's external power (Vcc adpater's pin to 2.8V logic board's testpoint & VccQ adapter's pin to 1.8V logic board's testpoint)
(the adapter is the one on the right side of the picture)

>>>>>replace the '*' with a '.'
----------Without adapter---------
Used USB cable to feed the Logic Board internally + HiPower CLK Drive Mode
#############################################
---------configs possible---------
tried all the combinations of eMMC voltages + eMMC CLK rates (with and without adapter
I tested all of this in the 3 phones that I mentioned above in an Windows 10 x64 Pro Desktop and then repeated all again in another different Windows 7 x86 Pro Desktop
The results were the same
In the 2 desktops I tried serveral Box software + Box firmware (downgrade too)
EasyJtag_Release_v1.0.105.0 (plus respective firmware)
EasyJtag_Release_v1.7.0.1 (plus respective firmware)
EasyJtag_Release_v2.0.5.0 (plus respective firmware)
EasyJtag_Release_v2.5.0.6 (plus respective firmware)
#######################################
JTAG reading:

after all of this I tried to JTAG the gt-i9205 follwing all the instrutions of the most recent 'EasyJtag_Release_v2.5.0.6' software suite. Using the USB cable + battery to power the logic boarfd as sugest by software suite, etc.. just to check if it could be a fault of the box.
Result: none....

What I didn't tried:
I didn't tried to dessolder the eMMC chip and read it directly but I don't see any advantage for me and my clients on that kind of service so I'm not interested in trying too
Last toughts:
For general users: If anyone have any valid sugestion please feel free to leave your answer and share your experience
For developers + official z3x supporters: it would be nice to hear any help from you. And if you think that this box unit can be faulty, please tell me so I can ask for a replacement on GSMServer seller
Best regards for all
