Hey, Im just telling you how I did it.
At any rate, when I was new to this and was reading freaking everything everywhere I ran into thet by member c3327101 called
XV6800 Upgrade sequence and followed some of these directions.
What you guys are looking for exactly though is in STEP 2
************************************************** ******************************************
STEP TWO
In the Hard SPL directory find this file, Hard_MFG_SPL_2.40_RUU_signed.nbh. rename or move it.
I just add a .DONE extension so the RUU won’t find it.
Extract this radio, Titan_radio_rom_3.42.40.zip and place the TITAIMG.nbh in the Hard SPL directory.

Run ROMUpdateUtility.exe from the same HardSPL directory, following the prompts until it says Finish.
This updates your radio on your phone

This is what I did and how I did it.
