Upgrading the IOS on my 2811 router from IPbase to Advipservices

I want to upgrade IOS on my 2811 router from IPbase to [c2801-advipservicesk9-mz.124-25a.bin]
via my USB flash drive. I have copied it the router boot system to boot it from the usbflash.

But when it starts to decompress the file the decompression is aborted in the middle and gives me the error "No interfaces found".

Can somebody tell me what is the problem? I have followed the following steps

boot system boot usbflash0:c2800nm-ipbase-mz.124-3i.bin

verify that this is the first boot command in sh run

with sh run | inc boot system

if so just do wr mem

- cisco will tell you that you must use a cisco usb device and that others are not supported;
- did you format the usb in the router? it might not support booting if not formatted in an ios device. safest to try this in a spare router, if you have one. if not, make sure you take a backup copy of everything in the router flash before trying a usb format, just in case! ("dir /all" to see what you need to backup)
