EVCS (screen) boot loop?

Yesterday I managed to get my EVCS installed. The interface looked nothing like what’s all over the internet so I did a firmware update via vrm portal. That was not a complete success as them screen showed: System Data ERROR!. So I decided to do another (manual) firmware update, using the (required) C025 version form the professional site. So now the screen is working, BUT it looks like the screen is stuck in a sort of boot loop. Every (lets say) 20 seconds it reboots fine and then after another 20 seconds this process repeats itself again and again.
Another reload of the new firmware does not solve this.
In the meanwhile I updated my GX10 to make sure thats not causing it (couldnt think why that should be possible).
Does anyone have a solution for this ?

Hello @RLE . I’m sad to hear that. I can check your EVCS. I will write you a PM.

So is a hardware thing. Those interested
