Cisco 3640 - Error : Uncompression of the image failed.

Having a problem booting my Cisco 3640 Router and get the following errors in boot "rommon" mode:

Error : Uncompression of the image failed.

invalid compressed data--format violated

Error : zip decompress failed

Does anyone know what might cause this and what I can do to get it booted up into IOS?

Thanks, Scott

Re: Cisco 3640 - Error : Uncompression of the image failed.

Update - I have already tried uploading a new image to flash: using the rommon> xmodem command and got the same results. Thinking that my flash SIMM card was toast, I then tried installing the IOS image from a PCMCIA Smart card. Again, got the same errors. Anyone know what might cause these errors and how to fix them?

Have you tried uploading different IOS files ?
