I took down the first and second test zips when I uploaded the one that is pre-rooted with the modem update built in. Also, There is no difference between flashing the first version(unrooted) with SuperSU and the modem update zip, or the second(pre-rooted) version with the modem update zip, or just flashing the newest version all by itself. Actually there is one difference. The newest version includes the new splash screen that came with the official lollipop update but that does not have any effect on installing xposed or anything else.
