When you connect the T56, look to arrow in the picture for the fw version, please post it, and the voltage you see displayed.
Also post were you get the messages for overcurrent, and version of software you use now.
Also, please post the IC were you see the problem, just to try the same here.

   Rgds

   Hello,           Based in what you wrote, several machines tried, several firmware loaded correctly, and my tests with my own T56,
it seem that you may have a faulty component in the ICSP area, a leak, but not a short/open circuit, as that will show in the test.
An example of a short/open circuit, and an area, you can see here Help me probleme t56 eror G-j1 - XGecu T56 使用问题解答 - XGecu Programmer Forums - Powered by Discuz! , just to show the area, and if the unit isn't on warranty.
T56  is also a bit sensitive to ground noise from machines with poorly designed power supply's, and i prefer to use it on USB3 ports. In the T76, they improve it a lot, at least my findings so far, and they have available better protected adapters for the job.
You can also try, contact the point of purchase, many times they help to get parts, and info, when needed.
If not tried yet, you may get extra help from their support at Contact US , as many times they are 'absent' from this forum.
Please, if any development you may have, post here, please, as it may help others.

   As i know, if you have a problem with the ZIF socket, just order a new one , and replace it, as the Zif is installed in a socket by itself... Please see link below, you do not even need to open the T56 :) but be careful a lot if you decide to it, and it's cheap. The initial kit from XGECU also bring the socket, just in case of damage/other reason. Warranty, i think, is one year, and yours T56 is out. You can also ask the dealer that sold you the unit.

   Hello, I think it depends of driver version used by the installer. .
Here tested:
Coright SKYPRO I, and it do not show to eject.
Xgecu T56 and T76, and SVOD4, all show to eject.

Hello again,
                  If you suspect that firmware is the culprit because it fail to load correctly, you
have two choices.
1-just wait that a new firmware, newer then the one already installed and identified by the Xgecu app, is available
   and it will, hopefully, show the flash enable, because newer version available. This happen often to add new features
   or correct bugs.
2-If firmware need to reload the present version, due to a failure loading it, or programmer not recognized at all, you may need to start an emergency firmware reload. You can see the procedure here Programmer not recognized after firmware update failed - T56/TL866II Plus新增芯片支持 - XGecu Programmer Forums - Powered by Discuz!

Overcurrent warnings from real use, are different from eventual bugs with no current load at all.  Current max level at T56 and app version 13.10, is 350mA, but to inform you, with T76 and app 13.11 is 400mA. If the 350mA current limit from T56, is 'real' safe max level, i expect to see Xgecu app, help users informing that alternate power feed is needed, and how to do it correctly/safely, or remove those ICs from support list :'( , as T56 is a discontinued product, it will, hopefully, have updates for some years, but that will reach an end. I'm expecting that will happen to programmer TL-866II sooner/later. Also, unfortunately, Xgecu manufacturer, did not timely update available information at it's site Haikou Xingong Electronic Co,Ltd as still show T56 in production, and that is, as i know, not correct, and even the 'blue prints' for T76 happen the same.

That is my personal opinion, but the risk is yours. Proceed, always, with care. Hopefully ADMIN will help you.
For sure, Xgecu products are great value for money, but not error free, as you can see with updates, they are always trying to improve :)

Let us know, please, any development you may have.

Thank You

   Hello,            Please, insist with manufacturer support, strong suspect of a leak in one of components,
then, hardware error, even if test pass ok. Hope they help You further, sorry.
Still digging in internet, if i find a similar case, I'll keep you posted.
