I have downloaded sysNAND from two different 2ds systems that are both on 11.0.0-33u. After running each one through Autofirm 11.0 there is no change in the files as checked by HxD and when I try to downgrade I get the "can't get am:u service". No emuNAND is installed, blank SDCard apart form the basic files required by Plialect's guide.
