Compatibility and risks

• Flashing the wrong image variant can result in: no HDMI output (blue light), bootloops, lost recovery, or a permanently bricked NAND requiring serial bootloader access.
• Differences that matter: Wi‑Fi chip (Realtek vs Broadcom), RAM size detection (512MB vs 1GB), partition layout (factory/system/data sizes), bootloader version, and DTB file.
• Safety: back up current partitions (recovery.img or full NAND dump) before flashing. If you cannot access the device at all, hardware serial (TTL) access may be required for recovery.

How to Check Your PCB Version:

1. Unplug the device.
2. Remove the rubber feet on the bottom.
3. Unscrew the 4 screws.
4. Gently lift the top cover.
