BD-UN-JB 1.1 — Advanced PS5 Jailbreak Disc

BD-UN-JB 1.1 — RemoteJarLoader for Already Jailbroken PS5

BD-UN-JB 1.1 is the next-generation Blu-ray disc designed for PS5 consoles that are already jailbroken. Unlike the classic BD-JB, this advanced tool extends firmware support up to version 13.20 and adds the ability to remotely load Java applications directly onto the console.

🎯 What is it for?

BD-UN-JB 1.1 is a RemoteJarLoader: it lets you load and run custom JAR applications on an already jailbroken PS5, hugely expanding the possibilities for homebrew development and console customisation.

✅ Supported PS5 Firmware

• ✔️ Support up to version 13.20
• ⚠️ Prerequisite: PS5 already jailbroken (via BD-JB or an equivalent method)
• ⚠️ Do not reinstall the firmware: doing so would remove the mod

🔧 Main Features

• 🔓 BD-J Unpatch — automatic removal of BD-J protections by sending bdj_unpatch.elf to elfldr, with automatic backup of the original file
• 📡 RemoteJarLoader — JAR loading server listening on port 9025
• 🖥️ On-Screen Logging — logs displayed directly on your TV
• 🌐 Network Logging — remote logging via RemoteLogger on port 18194
• 🔄 Compatible with any TCP client for sending JAR files

📋 How It Works

1. Run log_client.py to enable network logging
2. Insert the BD-UN-JB 1.1 disc into the already jailbroken PS5
3. The BD-J application starts automatically
4. Send JAR files via jar_client.py or any TCP client on port 9025
5. Make sure the Main-Class is set in the JAR manifest

⚠️ Important Warnings

• The PS5 must already be jailbroken to use this disc
• Do not update the firmware after installation
• Online play remains unavailable while the mod is active
• Keep the console in rest mode to preserve the mod without reinserting the disc
