How to downgrade the firmware 8.6.0 to 8.5.3 RMX 2000

Hi everyone,

 

Just in case someone faced something similar. I upgraded the RMX 2000 containing an MPMx card. Big error.

 

The system gets updated properly but card is not recognized.

 

I need to roll back to 8.5.3 but I cannot do it from GUI client. Any chance to do it via command line, serial?

 

The USB disk is an option? Has anyone used anytime?

 

Thanks a lot in advance, any help welcome

Why can't you do it from the GUI? This has happened to several other customers and all it took to resolve the problem was to push the 8.5.3 software back to the RMX.
