I will upload all the versions here.
***IMPORTANT*** Only flash 188.8.131.52xx radios where "50" on TMOUS. If that number is "51" it will brick your device.
Note: any radio version that is 2.04.50.xx or 2.05.50.xx will brick a TMOUS HD2, these were test radios for earlier HD2's treat them like .51 radios for TMOUS. (the first download has such radio rom)
This warning has been added since the roms below contain radio roms also.
