C3560 Unable to load IOS

Greetings All,

I recently bought a C3560 switch of off ebay for a home lab. The switch worked for a week and today when I rebooted the switch it  recieved the following messages:

switch: boot flash:c3560-ipbasek9-mz.122-55.SE4
Loading "flash:c3560-ipbasek9-mz.122-55.SE4"...@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
Error loading "flash:c3560-ipbasek9-mz.122-55.SE4"

Interrupt within 5 seconds to abort boot process.
Boot process failed.

So i downloaded the a new image, formated the flash and xmodem'd a new Image to try and fix the problem. However this did not help.

switch: format flash:

Either your flash is fubar, or you've downloaded a corrupt image.

The corrupt character at the start of the software line leads me to think the formar, rather than the latter, but you never know.

Try the image download/install process again, but if it doesn't work I'd be suspecting the flash. I've never pulled one of those apart, so I don't know if the flash is something you could source/replace yourself (I'm assuming, since you bought it off eBay, that there's no service contract).

Cheers.

The IOS is corrupt.

I have tried a few other images and that did not help either. I aslo found out that the 3560 does not have any field replaceable parts. So a quick flash swap I was hoping for is not a possiblility (or is it?).

Did you try to check the MD5 hash file is the same as the one published in the Cisco website?  If the hash file is not the same then either you downloaded an incomplete file or something is wrong with your client.

I did not check the MD5 hash file but I did try a few different IOS's. I also used an image from a working 3560.
