might not matter but the logical way is that
edit: i know why atse didin't work for you, type just "ATSE VMG8324" use zynpass from here
http://www.stkaiser.de/anleitung/zynpass/ZynPass.exeATSE VMG8324
generate pass in zynpass
ATEN 1, zynpassword
after that im waiting for outputs of the commands above
without ATBT it may be that firmware flashes have no effect for ATUR
edit: alright i dont know if the problem is solved but if it is + you have the full command list [with ATBT in there] then serial time is over, btw i had to re-read the same pages a whole lot as it was my first serial time xd
also note if ATUR indeed worked for you, ATBT was already set to 1
