You don't really need this rom to use wifi tether. Just do what I say, and you'll be fine. Google search and download WifiTether_TrevE_Mod_11_22_2012.apk. After you download it, you need to change settings as following otherwise it won't work(rest of other settings are up to you)
Device Profile: Generic ICS/JB (wlan0)
Setup Method: Netd-NDC (master)
Send Netd Max Client Cmd: Check
Wifi-driver reload: Check
Wifi-driver reload 2: Check
Keep Alive - Connection Checking: Check
Routing fix: Check.
I went ahead and made a video for this. Thanks a million. Works on the AT&T Note II as well
