⚠️ Realistic Constraints

• No secure folder (Knox) – Once tripped, Samsung Pay/Pass/Warranty void – this ROM assumes Knox 0→1.
• Camera might degrade – Exynos camera HAL is closed-source; expect basic functionality (GCam mod recommended).

Step 3: Flashing the Custom ROM (GSI Method)

1. In TWRP, go to Wipe and wipe Dalvik, System, Vendor, Cache, and Data.
2. Go back to Advanced > Fastboot (TWRP has a built-in fastboot mode).

4. Type:

   fastboot erase system
   fastboot flash system system.img
   fastboot -w
   fastboot reboot
