M2 - 5G Dev Board Connection issues

I have a Slate AX1800 and it had been working great for a while.

I am using it with both a T-mobile tablet sim with the appropriate magic applied, and also AT&T but it seems as if it just wont’ connect. it keeps cycling and this is what i get when I drilled into the logs… any ideas?

*****End

Tried on Firmware 4.5, 4.4.6, and now on 4.2.3 and still seeing the same issues.

Tmobile/ATT/visible all act the same and will not connect.

Are there any firmware updates for the m2 board?

I have taken the sim out and stuck it in a 4G Pulli and Collie - and it does work so I know the SIM cards are good - possiblt something with a driver stack or issue? looking for guidance for anyone also havin an M2…or other ideas…
