SKR Pro 1.2 w/ TFT 35

Hi Bob,
I tried reflashing to no avail… My board that works says: marlin 515D 2.1. 1
Machine: V1cnc 5150
Board: Bigtreetech GD_TFT35_E3_V3.1
Firm: V27.x Mar 10 2022
The new board that doesn’t work:

                                                               System:  unknown
                                                               Machine:  3D printer
                                                               Board:   Same   V3.0

Where do I change the System and the Machine description?
Can you tell me the exact MPCNC file to reflash? I also need the one to reflash the screen… I couldn’t find it on your email. With this firmware I can’t get Marlin to load but TFT loads but cycles over and over…
