Black screen now showing strange screen

[J2016denali2500]

2016 Denali 2500. Had the screen go black but still backlit. Radio still works with steering controls. Did battery reset, fuse reset, check all connections on hmi and wiring. Now a strang screen has came up... looks like a programming/info screen. And ideas if this is a software issue or hmi issue?

Same thing happened to me.  They had to replace the hmi module.
