Reactivate license from cli?

I have a 1500 running LTM 9.40 which is broken so I can't get to the web GUI, but I do have console access to the command line.

 

 

I don't need it fixed as I want to upgrade it to 10.1 and use it as DR.

 

 

Is there a way to re-acivate the license from the cli or would I be better resetting to factory defaults and starting from scratch. Or something else? Presumably if I did the latter I could obtain a new license from my third party supplier or F5 direct. It's still under support should I need something else.

 

 

Thanks.
