I was looking for a solution to reset my new spider v 20 because the presets would randomly change on me.
I went ahead and updated the Line6 updater which just itself got updated. (9-13-2019) Something like that.
I carefully read the how's and such, and you must find on your computer, under settings( the Windows Defender smart screen) and disable it.
Before you update the Line 6 Updater, because this interferes with the download of the Line6 updater( it says that the files get corrupt on the Windows platform).
I am using Windows 10.
Seems like a lot to do, but sure enough I was able to fix it no problem.
After you successfully Get the New Line 6 updater installed. Simply follow the onscreen instructions. The Factory Reset will Automatically take place.
Sure Hope this helps some of you!!!
