This is the latest firmware (T700XXU1ANF7) as of June 29, 2014 for the Galaxy Tab S 8.4 (Wifi) model (SM-T700).
"No-Wipe" means your app data and storage will all stay 100% in tact. Only system mods, custom kernels, and root will be removed as you are flashing stock firmware.
Please feel free to use as you see fit.
Same problem here, after following standard Odin procedure as described here: http://nasirtech.blogspot.ca/2014/06/t700xxu1anf7-android-442-kitkat.html
