Ouch - A bold move. Any chance you can verify your pedal is working as expected on some other device first? So we only have an SD40 at this point but we will have an Audya5 in a few days. Can't say until then how close the steps are between the two.

We published this video showing the backup options/steps on an SD40. Take a look - Maybe it will help? If you can wait a day or two we will give it a try on the new Audya5 and report back...
