Solution: You likely have a NAND flash chip (not eMMC). Android 9.0 struggles with old NAND. You must use a MultiDownload configuration (scatter file) instead of a single update.img. Look for "RK3229 NAND Android 9" on FreakTab.

Storage and RAM Management

• Swap – Not enabled by default, but custom kernels allow zRAM (256MB) for multitasking.
• Adoptable storage – Treat USB drive as internal (slower but useful for 8GB eMMC).
• F2FS – Support for /data partition if formatted accordingly.

a. Stock / Vendor Firmware

• Supplied by manufacturers (e.g., MXQ, X88, H96, T95 series).
• Heavily skinned, preinstalled bloatware, often rooted.
• Typically version RK322X_9.0_xxx_2021xxxx.img.

Bootloader and Kernel

• U-Boot 2020.10 – Supports multi‑booting from eMMC, NAND, or SD.
• Kernel 4.4.189 – Backported drivers; not mainline but stable for this SoC.
• init.d support (in custom builds) – For startup scripts.

Step 4: Erase Flash (Optional but recommended)

• Go to the "Upgrade Firmware" tab.
• Click "EraseFlash" . This removes old Android 7.1 partitions to prevent conflicts.

1. Superceleron’s "Pie Plus" Build (Best for MXQ Pro 4K)

Base: AOSP 9.0 Kernel: 3.10.104 Best for: MXQ Pro 4K, MXQ Pro+ (S905X clones with RK3229, check your board). Highlights:

• Overclocked Mali-400 MP2 (500 MHz).
• Fixed 1080p UI rendering (stock 7.1 often locked to 720p).
• Pre-rooted with Magisk 23.0.
• Kodi 19.4 pre-optimized.
