I have been given a Trinity with Xell and Aurora already installed but Xell, official dash in NAND and other things are out of date so I want to start a fresh NAND and HDD. I don't have the original virgin NAND or tools to do RGH3 but I just dumped the current glitched NAND through Ethernet which has all the vital files needed. How's the best way for me to do a new fresh updated glitched NAND with Jrunner?
