🔧 Android 14+ APEX Bypass

Starting Android 14, CA certificates moved to APEX module (com.android.conscrypt).

This module implements:

• Namespace Injection - Mounts into zygote namespaces
• Dynamic Re-injection - Service script reinjects after boot
• Per-process Mount - All app processes see the certificate

Verify Injection

# Check if certificate is in APEX
ls /apex/com.android.conscrypt/cacerts/*.0 | head -5

# View module logs
cat /data/local/tmp/ProxyPinCert.log

---

⚠️ Troubleshooting

"Certificate Not Installed" in ProxyPin

# 1. Check logs
cat /data/local/tmp/ProxyPinCert.log

# 2. Manual re-inject
su -c "sh /data/adb/modules/proxypin-cert-installer/post-fs-data.sh"

# 3. Force stop and reopen ProxyPin

"Unknown Publisher" Error

• SukiSU/KernelSU: Settings → Enable "Allow untrusted modules"
• APatch: Settings → Security → Enable "Allow unknown sources"

WebUI Not Loading

1. Ensure webroot/index.html exists in module
2. Check if root manager supports WebUI
3. Try reinstalling module
