Error in IOS transfer using Xmodem

[grapevine]

When I transfer IOS from  the desktop to a 3750 X switcch via the console at 115200 speed, the number of retries keeps on increasing and the md5 value dos not match the real md5 vlaue. Please tell me how can I mitigate this error and the root cause for the same.

The IOS was maybe currupted during download.  Try dowloading it again and than try Xmodem

3750X? Why are you wasting your time with Xmodem? How long does it take to transfer a BIN file to the appliance vie Xmodem? 45 minutes? A faster alternative is to boot the IOS via the USB stick. As long as you have a USB thumb drive formatted FAT 16 and the hardware is supported by the appliance, you can boot the appliance via USB. I've done this so many times.
