For starters, before updating, you need to reinstall the stock tune.
Then, read through the 'revision update instructions' found at the bottom of the downloads page.
Then, power the tool up to see what revision it is on currently. If it says 7r84, you need to do 8r10 then 8r17.
If it is on 8r10, you can go straight to 8r17.

Thanks
