I am still unable to upgrade it. It keeps failing.

Sorry, you need a DS.
Borrow one from a friend or go to a local store and ask to use it. :)

Do you know why it might be failing ? I ask this as I have the right version of the card and am on a lower firmware and it still doesn't work :/ Do not know anyone with a ds or someone who wouldn't mind me borrowing theirs!

This is to notify the people who might see this later on - They have still not completely patched all the "C" version cards of theirs'. That was my issue. Will have to wait for them to release a new patch!
