PS4 [BD-JB-1250] New Exploit (bluray) for PlayStation 4 supporting upto 12.50 firmware from Gezine

The PlayStation 4 has new BluRay exploit that supports upto 12.50 Firmware. Thanks to the efforts of developer Gezine, who has released the source code and helloworld.iso to complete the proof of work of this recent exploit for the PS4. Below you can see the readme for the project. Also some community reaction and comments about the new exploit for the PS4 from Abkarino & Modded Warefare dives into the exploit in one of his latest video attached below:

  BD-JB-1250​
  BD-JB for up to PS4 12.50
  This might be the exploit that was reported by TheFlow and patched at 12.52
  Nope TheFlow just confirmed this is not his exploit.
  lmao
  Just take my early Christmas gift
  No this won't work at PS5.
  
  Notes
  Change Status.java ip address for network logging.
  Default is 192.168.2.1
  For compiling I recommend using john-tornblom's bdj-sdk

  Credits
  TheFlow - for his BD-JB documentation and sources for native code execution
  hammer-83 - for his PS5 Remote JAR Loader, it helped me a lot to learn how BD-J works
  john-tornblom - for his BDJ-SDK, I couldn't have compiled PS4 BD-J without his BDJ-SDK

  A new BD-JB userland exploit had been implemented by @gezine_devthat support PS4 up to 12.50So this will be a very easy to use exploit rather than Lua method for all people who does not have Lua games activated on their consoles

I don't have a usable Blu ray disc rn but I could get one for my BD drive eventually for the PS4 on my current firmware 12.50 since I haven't updated yet to 12.52 luckily.

Unfortunately BD-JB isn't too useful on 12.50 due to the lack of a kernel exploit. The most recent kernel exploit found was Lapse, which works up to 12.02.

 

On 12.50 you can run emulators such as NES, SNES, Mame. True or false ?

Mostly false. You can't install FPKGs without a kernel exploit. The userland exploit by itself only lets you take over the BD player process, but you're limited to whatever the BD player is allowed to do, which is not a lot.
Technically, you could port an emulator to run as a BD-JB payload (rather than its own app), but I doubt anyone would bother. If I'm not mistaken you'd also need to burn the ROMs on the BD-R itself, because the Blu-Ray player process doesn't have access to USB disks.

EDIT: The above info is outdated. It's now possible to jailbreak up to 12.52 using BD-JB+Poopsploit, and apparently 13.00 might be coming soon using either a new BD userland exploit or a variant of poops that can be used from LUA. 13.02+ is not known to be jailbreakable at the time of writing this.

 

Hi. In what forum is this being discussed? I think this is a major news but is not being discussed in here!

 

Im still on 12.02 bd-jb , im waiting for 13.00 jb it seems interesting
