Hi there,

As for the router - it looks like it doesn't know what file it's pointing to. In rommon, you can have a look at the files in flash and then change the boot to point to that file. Something like "BOOT:"flash:c2600-iz-122.bin"

The switch seems to have the same problem. The file that it's looking for is not there. Go through a similar procedure for the switch, find the correct file name and alter the BOOT variable and make sure it pointing to a real file!

getdevnum warning: device "flash" has size of zero

open: read error...requested 0x4 bytes, got 0x0

For the router, those lines above implies that the flash is probably not seated properly or the flash is bad. Try to open the router and reseat the flash. If the problem persists with the same error, change the flash.

Check the following link

Error loading "flash:c3750-i9-mz.121-19.EA1c/c3750-i9-mz.121-19.EA1c.bin"

For the switch, the switch cannot locate the IOS image. Use the dir command to confirm if there is a valid image in the flash. If there is none, use xmodem to copy a new image into the flash and reboot.

Check the following link

Note, that after reseating or changing the flash of the router, it probably might be in the same state as the switch i.e. having no IOS image on it, and not able to boot. What to look for is that you will stop getting error
