I am trying to upgrade a 3750-24PS. No matter what image I try to upload I get a error when booting.

flash:/<IMAGE_NAME> magic number mismatch: bad mzip file.

I have tried every single 12.2(25) image I can find on CCO and they all return the same error.

Anyone seen this before?

I have seen this before on a different model 3750. I ended up calling TAC and received an RMA for the switch. Before that, here are the steps I went through:

1. verified the image (verify flash:/image_name

2. ran fsck on flash

3. formatted flash completely

4. copied image via xmodem

none of these steps proved successful im my case.
