i highly doubt that that method is easier than simply plugging up ur 360 to the local network,running dashlaunch,and enabling updserv,then one click in jrunner bam its updated.and less risk of messing it up than with flash360.but its ur box do it how ya want.
So, I got my hard drive today, and started the update proccess with J-Runner (I have FSD 775 and Dashlaunch 3.14 (571), this is what I did, enabled updserv in DL, in Jrunner loaded in Source my nanddump, previously I went to Advanced>Get latest System Update, went to Patches/Dashlaunch tab and checked "Use Dashlaunch" and "Include Launch .ini ?", then in Update Mode tab it says 1750, I clicked Update, and the log says this:
