I saw on his presentation months ago that the xbox one is also affected by it, so any hope for a jailbreak with this?
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

how does someone start with doing this

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.

More info:

A list of homebrew games you can play through this method:

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

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

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.

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.
