🛡️ Aurified-NET - Retroid Pocket 5 Edition

A secure, auditable rebuild of the original "SPPH ULTRA NET" Magisk module.
Removes obfuscated code, eliminates security risks, and optimizes network latency for handheld gaming.

⚠️ Why This Fork Exists

The original SPPH-ULTRA-NET module contained heavily obfuscated code (eval, variable concatenation) in its service.sh and system.prop files. This practice is a major security red flag, as it prevents users from auditing what the module actually does.

This fork:

• ✅ Removes all obfuscation: Every line of code is transparent and readable.
• ✅ Eliminates security risks: No hidden backdoors or malicious payloads.
• ✅ Focuses on proven optimizations: Only applies settings that are safe and effective for the Retroid Pocket 5.
• ✅ Graceful degradation: If a feature (like BBR) isn't supported by the kernel, it skips it without crashing.

🚀 Features

1. TCP Keepalive Tuning (Verified Working)

Reduces the time it takes to detect dead connections, crucial for online gaming stability.

• tcp_keepalive_time: 30s (Default: 7200s)
• tcp_keepalive_intvl: 30s (Default: 75s)
• tcp_keepalive_probes: 3 (Default: 9)

2. IRQ Affinity Balancing (Verified Working)

Moves network interrupt handlers (WLAN/ETH) to a dedicated CPU core.

• Benefit: Isolates network processing from the main gaming cores, reducing input lag and micro-stutters.

3. Connection Tracking Optimization (Verified Working)

Increases the NAT table limit to prevent "Connection Lost" errors during heavy multiplayer sessions.

• nf_conntrack_max: 65,536
• nf_conntrack_buckets: 65,536

4. BBR Congestion Control (Conditional)

Attempts to enable BBR (Bottleneck Bandwidth and RTT) if the kernel supports it.

• Note: If your kernel does not support BBR (common on stock kernels), the module gracefully falls back to cubic without errors.

🛑 Removed Features (Due to Kernel Restrictions)

To ensure stability and prevent errors, the following features from the original module were removed as they failed to apply on the Retroid Pocket 5:

• ❌ DNS Changes: /system/etc/resolver.conf is read-only on modern Android ROMs.
• ❌ WiFi Power Save: The power_save sysfs node is missing on this device.
• ❌ TCP Buffer Tuning: tcp_rmem/tcp_wmem writes are ignored by the kernel.
• ❌ Obfuscated Logic: All eval statements and hidden code blocks.

📥 Installation

1. Download the latest .zip release from the Releases tab.
2. Open Magisk Manager (or KernelSU).
3. Tap Install → Select and Patch a File (or Install from Storage).
4. Select the downloaded .zip.
5. Reboot your device.

Verification

After reboot, run the following commands in a terminal (Termux/ADB):

# Check Keepalive (Should be 30)
cat /proc/sys/net/ipv4/tcp_keepalive_time

# Check Congestion Control (Should be 'bbr' or 'cubic')
cat /proc/sys/net/ipv4/tcp_congestion_control

# View Debug Log
cat /data/local/tmp/net_debug.log
