In theory, it could work for booting backups burnt to a disc but I don't believe anyone has managed to pull it off. As far as leading to an actual jailbreak of the console for homebrew outside of dev mode, it's not likely
The tech is available on the Xbox One. We would need to dump the interpreter's binary and look for vulnerabilities.
Using this image: https://www.mediafire.com/file/6a6aexvvm36o3t3/Doom-BluPlay.iso/file (by Shykelit above, who sent me the image months ago at the time of the Tweet). This is just executing Java code contained in the bluray disc.

As for reversing & exploiting the interpreter: it's very easy to obtain the binaries from a dev-mode console nowadays, so it isn't a far-fetched idea to maybe look up for vulns. If anyone wants to look into it feel free to ping me btw
So realistically speaking, this is the only method someone can make a way to hack an xbox one

Wonder if it will be possible to transfer over the contents of the Xbox One's memory to a PC via FTP with this method in mind?
We should do some testing and post the results, its dire in the xbox one scene lol

I am interested in finding some vulnerabilities but i have no idea how to and where to look lol, i already have dev mode and everything
Last edited by XboxModder2,
When you test it could you come here and let us know the result? Very thanks.
I got my xbox one ready and dev mode too also with bdjb, so how do i start looking for vulns
yeah the only thing that was said related to it is "so it isn't a far-fetched idea to maybe look up for vulns.", never mentioned where to look for the vulns or how we can do it lol
BD-J and BD-JB are not the same thing. BD-J is a standard feature on all Bluray players which follow the standard properly. It allows java code execution in a sandboxed environment. BG-JB specifically targets the PS4/5 implementation of BD-J to allow for full userland code execution. While possible that Microsoft made a similar mistake with their implementation, it's extremely unlikely to be 1:1. Though it is a possible entry point to start looking for vulnerabilities.
no worries

ah i see, thanks, so bdjb is the only way forward right?

this video shows that the BD-J exploit works though
Because BD-J is not an exploit. It's a feature of the Bluray standard. Easiest way I can try explain is imagine you have BD-J which is like 10% of the system's functionality unlocked (But planned like that by Sony/Microsoft/etc). BD-JB exploits the already unlocked 10% to unlock an extra 40% of that functionality, which is the exploit part of this all. (The percentages are just arbitrary numbers with no real meaning other than to portray my point.)
The names do cause a lot of confusion, but there is a big difference between the two.

Yea but to play the next gen games, you must have those games on internal, or buy the official ssd expansion cards, which are expensive -

A surge protector is a device that protects your electronics from fluctuations. I recommend having your console plugged into one of those -

An UPS is even better because it has an internal battery that keeps your system on even if the power goes out, but it's much more expensive obviously

@MysticStarlight, although whatever device we plug into them stops getting power anyways lol

On the series s/x you can use a external HD but any next gen games must be on your internal ssd, or you can buy a ssd expansion card, but pricey. Any xbone, 360, or og Xbox games can be played from external tho.
