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

reload

- 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)

what exactly do u mean by not supported because the usb that i was using was working i-e it was showing me the contents of the usb when I give this command (dir /usbflash).

"not suppported" means that if it does not have a cisco brand on it and if you ask them for help, they will tell you to get a cisco sub stick to prove that the problem is not with a non-cisco usb. some cisco memory is specially modified/manufactured so that it wont work in a pc and standard pc memory wont work in some routers - 37xx series is one i know of.

in my experience (working in cisco tac for 6 years) i often saw devices that were not officially supported, being used in devices. most of the time it was fine, but often (very commonly with the old compact flash cards), you needed to format the card in the device you want to use it in. a cf card formatted in a pc would show the code when installed in a router, but it would not boot. once the card was formatted in the router, then moved to a pc and the code copied on, then put back in the router and it would boot fine. this might not be the answer to your problem but it should only take 5 minutes to test the theory.

another option you might try is to insert the usb and copy the code to the internal flash, then change your boot command to refer to flash rather than usbflash. or you could use ftp or tftp to get the code into the router.
