I'm assuming you had the shell off, right?
I would honestly go back, remove the shell, and check all the connections. I had my LC+2.0 shell off for some work. When I put it back together, I pinched a wire. Fixed the wire, still had the problem.
Then I discovered I had a wire plugged into the wrong port. I fixed that and things went back to normal.
I didn't have your exactly symptoms but it's worth going back in to check the wires.
