RE: Cannot change set BAUD 115200 in CISCO2811

Hi guys, I cannot  set BAUD 115200 in CISCO2811  or even erase contents of the flash , all I get is error like what I have in the following display.

This error that shows up several times during the attempts to boot the router indicate that there is a problem with the image loaded into flash

loadprog: error - Invalid image for platform

I would guess that you have attempted to upgrade the image and copied an invalid image into flash on this router. I would think that something like tftpdnld might allow you to copy a valid image (assuming that you do have a valid image) to the router and to boot it.

Exactly what are you trying to achieve?  

If you're planning to push a correct IOS into the switch, then doing ROMmon is a very, very old, archaic and backward method.  Why? 

ISR G1 and G2 (except the 800-series router) have CF slots and USB ports.  All you need to do is eject the CF, get a memory card reader and copy the IOS from a machine to the CF.  The entire copy exercise will take about 5 minutes compared to 20 minutes using ROMmon (115200 baud rate).  

IF the router's bootstrap has been upgraded, you can even boot the router using the USB port.
