ICD-U40 upgrade error

[Wanchope. H]

Dear friends,
I am now having a problem to upgrade my firmware into the ICD-U40. When i import the Ccsicd40.hex file, the MPLAB prompts an error 'The checksum in the hex file is incorrect; the hex file appears to have been corrupted.' What could be the cause? Is it corrupted like it said? If yes, could anyone tell me where i can get a valid copy?
Thanks very much.

I think you need to use icd.exe from CCS to upgrade the firmware as the hex files provided are reliant on the bootloader that is already resident in your ICD-U40 and MPLAB doesn't understand any of this.

This may be incorrect advice as I don't use MPLAB so if so others please correct me and proviode the proper advice.

Thanks, ajt,
In the following link, i can see that the guest is using the ICD-u or ICD-s to re-program the bootloader and firmware into the other ICD-u or ICD-s.

Can i do the same using PICSTART-plus under MPLAB environment? I guess so. But when i 'import' the Booload.hex under MPLAB, it said ' The end of the file has been reached unexpectedly; the hex file appears to have been corrupted.'
why this happens? pls advice.

I am foggy on my recollection here but I think there are some comments at the beginning of the CCS bootloader.hex file that should be removed as MPLAB can't handle it.
