So I have a broken Xbox 360 (not red ring of death, though I’m not sure what it is if I shake it something rattles around) and it’s power brick and kinetic. It has Minecraft stored in it- my main issue is since it won’t turn on I don’t know how I can reset it before selling it (I have another one) can anyone steal my personal data or anything like that via the Xbox? If so, how do I remove the data? Is there a quick fix for this or should I sell it as is? How much is it worth? Any help would be appreciated

So basically, I jailbroke my Xbox 360 and downloaded retro arch from the homebrew store, and when I opened it, it gave me the normal intro screen, but then from there no matter what button I press it sends me to a list of cores, and if I press button again, it sends me to a list of files and then retro arch crashes and send me back to the intro screen. Any help would be appreciated thanks. No ai can figure this out apparently.
