• 📦 Officially (MIUI Stable/Developer) — download MIUI Downloads. Pine is suitable for the Global Region, EEA (Europe or India.
• 🔧 LineageOS (Pixel Experience) – requires an unlocked bootloader and installed TWRP. Downloading from forums XDA Developers or 4PDA.
• 🔄 Port firmware – informal builds based on MIUI Risky, can contain errors.
