I'm actually wanting to update the bios and everything else in it to the latest version, but I'm not sure how to do it exactly. Is there a guide I could follow? Could I do it all over ftp? I'm just not sure where to start exactly.

Hey guys, Bought a second hand xbox that came hard modded with a sst 49lf020. Seems this xbox hasn't been used in a while as some of the apps are a couple of revisions behind. Should I wipe it clean and start again? Should I buy a different modchip? Attached an image below of the details from EvoX.
