Problem downgrade ios 2811 124-15.T13 to 124-15.T7

[service-realisation]

Hello,

I'm trying to downgrade an 2811 of 124-15.T13  to 124-15.T7.

I can without problem (with TFTP) copy a IOS T7 over the flash and I can see it with sho flash:

copy tftp flash:

boot system flash c2800nm-ipbase-mz.124-15.T7.bin

copy running startup

reload

Unfortunately, during the reloading we can see "problem checksum" and the 2811 reboot over the ios T13

Can you say to me if I make an error in my procedure or exist it a true problem?

TKS a lot

I tested again this morning 2 procedures.
Here recovered logs.

copy....

Can you post a dir flash:

Can you also post the complete boot log when the router is reloaded?

Your T7 image could be corrupt.

[Richard Burts]

We do not have enough information here to say for sure what the problem is. The procedure of:

- copy tftp: flash:

- show flash

- change the boot system commands

- copy running startup

- reload

sounds like the correct procedure. If it is not working it would sound like there is a problem with the IOS that you copied to flash. Perhaps you could post the output of show flash and this might provide some insight into the problem.

[Phillip Remaker]

Issue the "verify /md5 flash:filename" command at the CLI to see if the MD5 matches the one on the download center.  Sounds like simple file corrution.

A copy of the exact error message text and a directory of the flash could be enlightening.
