Reinstall IOS on router 871 W

cephasattica · ‎05-05-2009

I have an Router 871W with no bootable image file. I tried to upload a new IOS using hyper terminal and xmodem but get an error message ERR:Image size exceeds free flash space.

How do i re-install the IOS?

I have attached text from hyper terminal.

Hi,

You need to delete your corrupted file from ROMmon before uploading the new one via xmodem

Please follow the steps described here:

You can also try to use the "tftpdnld" feature.

Hope this helps.

The error makes me think your IOS of choice is > than the total amount of flash?
