[Milo Wilson]

Go into diagnostics and do an NVM init.

on the 260 I can not connect to it with diagnostic navigator only through the download navigator and it shows nvm errors and the machine does not boot up

how do you get into diagnostic mode on the nuvera?

[Milo Wilson]

On the machine itself. Like logging into a docuSp server. If the license string is not active then you have to get a new diagnostic license string before going into Diagnostics.

You need to restore nvm or replace Sw/NVM module and restore nvm.
You dont have service manual ?
