Boot router from ROM and take it from there.

Rock,
I'd suggest that you follow CCO's IOS Upgrade procedures for the routers
with RO Flash you may have. The fact that those routers have Read-Only Flash
type, doesn't mean that you can't erase and upload a new IOS image.
Read-Only FLASH memory requires a different method of "erasing" its
contents. The delete and squeeze commands do not apply to them. Cisco's
upgrade method for those routers that use Read-Only Flash, includes a couple
of steps that will apply a high enough Voltage level to the Flash that will
blank its entire content, and then copy the new IOS image in it.
Of course, there is a chance that you could have a router with "defective"
Flash, meaning that it would not accept new images because its "delete"
function no longer works.
Please visit this CCO URL for upgrade procedures:

Hth,
Angel

Subject: IOS Upgrades [7:45128]
Hello group,
After the announce on SNMP and NTP vulnerabilites we are doing upgrades on
our routers with Cisco's recommandations.
We are having difficulties with one of our router that has it's flash in
Read-Only. Which make it impossible to upgrade I think. Do you have an idea
on how to upgrade an IOS on a router with a Read-Only flash.
Any information is welcome.
Thank you.
Rock.
