I have the same issue @IsraelMeshileya. Did you get it working again?

This was quite insightful, I think I'm having a similar issue, my touchbar was working perfectly fine but I cut part of the cable during a keyboard replacement so I ordered a new touchbar flex cable and now it's dead and shows no options in mac os despite it being connected with a brand new flex cable. Just curious, do you have any updates on this?

Did you have any luck with this? I have no Apple support in my country and it's weird how fragile the Touchbar is.

@negacao Yes, I triple checked all the cables and connectors and made sure everything was making full contact and was seated correctly. I also made sure not to over tighten the cable connector covers because I've read that it can cause poor contact.

But I cut it when the battery and everything else was disconnected so that's probably not a possibility?
