# BD-UN-JB

**Note : YOU NEED ALREADY JAILBROKEN PS5**

BD-UN-JB is RemoteJarLoader that can be used on already jailbroken PS5 upto 13.40 firmware.   
It supports on-screen logging and network logging.  

Send bdj_unpatch.elf to elfldr to unpatch BD-J.  
bdj_unpatch.elf will backup existing bdjstack.jar to bdjstack.jar.bak just in case.  

Then burn BD-UN-JB iso and run.  

**DO NOT REINSTALL FW, IT WILL WIPE THE PATCH AND LOSE BD-JB**

RemoteLogger server is listening on port 18194.  
Use log_client.py to get the log.  
I recommend first running the log_client.py then starting the BD-J app.  

RemoteJarLoader server is listening on port 9025.  
Use jar_client.py to send the jar file.  
You can use any other TCP payload sender too.  
Don't forget to set Main-Class in manifest.txt.
