Recently ordered two bundles (Giga & Display). Similarly to you guys, I am in the same situation with the "Touch controller init - FAILED" and the Error 2 for both addresses, but only for one of the two bundles.
First bundle is working good, second is not. This begs the question, what happens if I switch the Displays ? It works...
So, it seems the problem comes from the Giga itself instead of the display.
