LimeSDR dead, flashing does not help

Same for me. My board worked ok in the past with old GW. Newest sometimes flashed but most of times showed version 0 revision 0 and did not work. Back to old - works again. My friend’s board works fine on the same setup same cables etc with both old and new GW. With some more digging I reached to conclusion that the problem is with FX3 usb connection. My board caused many error on loopback test (while my friend’s caused only sporadic error).
Also problem was more severe when board was cold (room temperature). When board warmed up due to self heating problem was less severe.
As of right now I did send my board to Lime Micro. Still waiting for response.

Maybe older versions were less prone to usb communication errors.

Test I mentioned:
