Firmmware update failure Canon EOS 6D

[coldwaterjohn]

Despite following the download an application instructions assiduously, I keep receiving this error message:  

"Firmware Update Program: Update File Error. Please check the memory card and reload the battery and try again."

I have also reinitialised the data card, without success in updating the latest FIR.

How do I go about overcoming this issue with my Canon 6D?

1. Exactly which card are you using?
2. Which firmware and which file size if you check the unzipped file?

[coldwaterjohn]

I am using aScandisk Ultra 64GB SD Card.

My 6D was running on 1.1.18 and I am attempting to update to Firmware 1.1.19

[Peter]

In my opinion no need to update if you don't connect your camera to an unsecure WiFi access points. How often do you do that?

Thank you for that suggestion. However Iam at times connecting through "unsecure" wifi points, however even if I was not, this does not explain why Canon firmware will not upload into the Cano 6D. The FIR file has transferred to the SD Card and is showing on the root directory. Wht is not appening is the update from the card to the camera itself.

1. Try 32GB card or smaller file size.
2. Low level format the card.

3. Check the file of when the file is extracted onto the card, 6D000119.FIR should be 21,346,096 bytes.

This may be the reason for the failure...the downloaded  6D000119.FIR on my P.C.is showing as 20,846KB bytes.

I have tried downloading it twice now with same result???

I have also tried downloading from this site: https://in.canon/en/support/0400526302/1

where indeed it shows as supposed to be of the byte size you indicate. However when you download the zip file and extract it, it comes out at the size I have already indicated to you...couriouser and curiouser!
