I have a G250 that, after an attempted firmware upgrade will not initialize. It attempts to boot up, and passes all self tests but gives an exception:

EXCEPTION_RESET_TYPE Exception in tExcTask

Here is the complete contents of what I see on the console port when I power the G250 up...

This problem began after I had attempted a firmware upgrade from my CM5 upgrade/install. The installation wizard timed out while doing the post-flash reset of the MGP. My question is, how can I go back and flash an earlier firmware load into the MGP? Is there a way to perform a reset at the hardware level, or anything else that would allow me to restore an older set of firmware?

if you can't get to the MG-001-1(configure)# prompt then you have no choice but to replace the gateway..

Yep, that's what I'm going to do. Thanks!
