First, in the future, read before leaping -- it's well known that ART cannot work with a Sense based ROM -- it's totally broken and it will surely do bad things. If you want to know why it's so hard -- it's because your device is totally screwed up now.
First, your /system partition is probably trashed -- so that's why PhilZ says you have no root access -- you don't, there's nothing worthwhile at all on your /system partition.
Before you go too far, please tell us all what your firmware versions -- look for the 'OS-???????' on your bootloader screen. That will dictate with RUU you will want to use if necessary.
There's a couple choices:
1) *if* the ART mess didn't totally screw up your internal storage, you have a shot at loading a ROM and moving forward (see if you can look at the internal storage in PhilZ, to go 'backups restore' menu, and try to load from /sdcard -- hopefully it can see the file system, if not -- you better RUU so see below):
a) Place a valid ROM (my suggestion is use benny3's stock, rooted ROM so you get to a place of sanity) on a exFAT, ext4 or ntfs formated USB stick;
b) Boot into recovery (PhilZ is apparently working for you -- whew!):
c) Plug your OTG cabled USB stick in to the device (PhilZ will mount the USB drive);
d) Use PhilZ to 'wipe to load new rom' in the menus;
e) Load the ROM from /mnt/storage/usb.
2) *if* the ART mess screwed you totally, you'll have to RUU back to stock:
-- Start with Q16 in that FAQ.
We can help -- don't rush. Also, plug your device in, PhilZ will charge the thing and you want it charged reasonably before you get started.
