Note : YOU NEED ALREADY JAILBROKEN PS5

BD-UN-JB is RemoteJarLoader that can be used on already jailbroken PS5 upto 12.00 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.

Use john-tornblom's bdj-sdk and ps5-payload-sdk for compiling.
