IF you get an error saying "E3004: This package is for device: TB-8504X,TB-8504F,tb-8504x,tb-8504f,tb_8504: this device is *your_device" then
You are trying to flash this to an unsupported device
You need to unpack the zip file and in "META-INF/com/google/android/updater-script" delete every line of text until "ui_print*", then save updater-script and repack everything into a zip archive and flash in TWRP.
This was posted by the rom developer, go to Page-2 of this thread and have a look there if you want...
Edit: Let me know if it works/doesn't work...

Also, don't wipe the stock rom boot and system partition before installing this zip file, only format the data partition if you want to, because wiping the system partition and then installing this zip causes the os to not boot (boot partition can be wiped, but just to be safe, don't wipe it...)
