DMR+ not connecting following upgrade to 4.1.7

[G4CTP]

I'm trying to help a friend out, who seems to have lost DMR connection following upgrade to 4.1.7.

He has sent me screenshots of his config, and all looks good - identical to mine apart from the fact that he's using Phoenix F as the DMR Master and I'm using DMRGateway. But other than that, all the settings look good, and he hasn't changed anything prior to or during the upgrade.

However, "DMR" is red on the Dashboard Modes Enabled, as is "DMR Net" under Network Status.

I'm a bit at a loss as to where to look to try to diagnose the problem. Any thoughts or clues?

Oh, hang on a minute - he may not have done the "sudo pistar-update" step. Stay tuned...

Fixed.

It needed the MMDVM firmware upgrading - twice, because we didn't know the crystal frequency. Followed by restart, toggling DMR Mode switch, another reboot - and then it came back to life
