Alright thanks I'll give that a shot. yeah by etc I meant for each image i would use the fastboot command to reflash that image separately. I figured fastbooting each image individually was the safest way to go, as I know exactly what was done. Does matt's utility basically do the same thing when selecting the option to "restore stock", but in a batch function? I never used his utility to revert back to stock, have always done fastboot to this point. I may have some time tonight to try this again.
This. Basically your partitioning is probably no longer stock due to tinkering and needs to be wiped out and reset. RSD will do this for you automatically. Not sure if matt's util does.
