IOS Upgrade

I have 3560 switch, I uploaded the latest ios version to the switch and when I reload I get this message "Error loading "c3560e-universalk9-mz.152-4.E8.bin"" and it reload itself again.

 

Is there any solution to fix this issue?

Re: IOS Upgrade

Hello ahmed,

use the password recovery procedure to make the switch to stop at rommon mode (you need a console connection and access to the switch to press and release the mode button if I correctly remember)

 

see

https://www.cisco.com/c/en/us/support/docs/switches/catalyst-2950-series-switches/12040-pswdrec-2900xl.html

 

From there you can mount the flash filesystem and you have a chance to boot with the old image if it is still on the flash:

 

You may need to upgrade the ROMMON to be able to run the new IOS image. You should read the release notes for the target release.

 

Hope to help

Giuseppe

Re: IOS Upgrade

This has been my experience as well, ROMMON likely needs updated.

Console into the switch and reboot.
Post the entire boot-up process. We want to see what the switch is actually doing (or trying to do).
