Tethering on the N910t3

On my regular N910T I had a 5.0.1 Rom that had working unlimited tether, but I got a replacement device because of GPS problems and it came with 5.1.1 (N910T3) and I couldn't find any way to have unlimited tether... So if anyone has a working solution for unlimited tethering on DOG1 for the N910T3 I'd really appreciate it. (I tried the IPV4 apn and wifi tether router and also the modded tether apk from the s4 forum both didn't work)
