How to upgrade Rommon Router 2921

[mdrangell22]

Hello Guys

I have tried to find the procedure to upgrade Rommon to Router 2921 but I haven't found something specific.

I Think I have to upload the Rommon file (C1900_2900_RM2.srec.SPA.150-1r.M16) to my flash and then to use the command: 

R1#UPGRade rom-monitor file flash0:C1900_2900_RM2.srec.SPA.150-1r.M16

and after that the router will restart and I should have the new rommon version? Is that all the procedure or did i miss something?

upgrade rom file flash:C1900_2900_RM2.srec.SPA.150-1r.M16

Use the command to apply the patch. 

After the ROMMON has been "applied" (with the command above) reboot the router for the ROMMON to get upgraded.
