Flashing help.

So I have been researching on how to have unrestricted hotspot on my g20t on metro pcs. So I did read on another post that metro/tmobile uses their native hotspot in tracking usage. My thought was two remove it but to no avail. So my next theory was to flash a unrestricted rom on it and see if that would work. Has anyone done this before and had success. I have tried wifi tether router and I can't use fox first as it says my phone is not supported. Right now I am on the twisted rom for MM....
