Default [Q] Touch firmware update on aosp ROM?

So the d2w feature stopped working for me today and I am sure that its a touch firmware issue. I just don't really want to have to spend the next 3 hours downloading a tot file to restore my phone and then manually update to kk and then root it so I can install that app and then update the firmware. There has to be a way to do this on an aosp ROM
