Hi Community,
i have some problems to use my cisco c2811 router. After accidentley deleting the flash:/.bin file, my IOS is not available anymore. For that reason, after restart, the router is in a continous loop with boot: cannot fload "flash"
Is there any possibiliy to setup the device with new IOS file, which could be installed from usbflash1: e.g.
I cannot enter break sequence (CTRL+BREAK over Secure CRT).
Error code:

Is there any possibiliy to setup the device with new IOS file, which could be installed from usbflash1: e.g.
To get the ISR G1 to boot an IOS (from ROMmon) using USB flash, the ROMmon itself needs to be upgraded first.
Next, is there a compact flash currently in the slot? If so, eject the CF and copy the IOS into the CF using a multi-card reader.

Hi Leo,
i was not aware, that it is "so" easy to just copy the IOS file to the CF card.
This worked directly (more effort to find a card reader :) )
Thanks for your help! Appreciated!
