3750-PoE bricked - Magic number mismatch?

Hi,

I have a 3750 PoE which I was trying to get the image off by doing a archive upload-sw...... but as it got to the image file it said the file/device was busy and gave up.

I executed the reload command and since then I've had this error message which doesn't allow the switch to boot its IOS:

switch: boot

Loading "flash:c3750-i5-mz.121-19.EA1c/c3750-i5-mz.121-19.EA1c.bin"...flash:c375

0-i5-mz.121-19.EA1c/c3750-i5-mz.121-19.EA1c.bin: magic number mismatch: bad mzip

file

Error loading "flash:c3750-i5-mz.121-19.EA1c/c3750-i5-mz.121-19.EA1c.bin"

Interrupt within 5 seconds to abort boot process.

Boot process failed...
