It is certainly true that the 2500 series routers are run from flash routers and that makes the flash read only in normal operation. And certainly one way to upgrade the IOS is to boot to rommon (or even better to boot to rxboot) which will make flash read/write and allow the image file to be replaced.
But Cisco provided the Flash Load Helper feature to work around that aspect of operations. I am surprised that FLH did not kick in and do the upgrade. The FLH should prompt for the parameters of tftp host, new image name and then did the boot to rxboot in the background.
The original post show the command as copy tftp: flash:. I wonder if the colon affected things since the old 2500 code did not use them. I wonder if you just enter copy tftp flash (omit the :) if FLH would work and make this operation more simple.

This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
