Sold My Gryphon and

[svt2205]

I'm looking to see if I can, well you guys, can help out the new owner of my Gryphon. I returned the tuning to stock before selling my old truck. Then I ran the updates to purge the custom tune and restore the unit to it's canned state.

Now the new owner is getting this error, "checksum failed RXAP9B6" when he tries to load #2.

Any suggestions? I've not had any issues with the unit during the 2 or so years I had it. And I want the new owner to be happy with his purchase.

Please help
Thanks
