Have you connected a PC to your Gemini over Ethernet or USB or Serial? While the HC is not starting up, does Gemini respond to commands, report status, track at Sidereal, slew/goto, etc.?

I realize this is an ancient topic, but I hope there are new things to try.? I took a stry G11 in and the G2 controller has this problem: G2 powers up, the hand controller displays the "welcome screen and the recalibration screen before switching to the black screen with "Connecting to Gemini" at the bottom.? And there it stays.??

- I checked the battery I use as a power supply and it's fine.
- I changed the internal battery first off.
- I've reseated both mini-SD cards.? I notices there is a 2GB card in the G2 controller and a 4GB card in the hand controller.? Could they be reversed?? Is this a possible solution?
- I've tried four different cables.? Admittedly none of them is confirmed to work with a Gemini controller, but two of them work with old stepper motors, so some of the conductors are continuous.
- I've tried each cable is both Port 1 and Port 2.??

Does anyone have any other ideas?
