: Source for specific kernel and bootloader images for Allwinner H616/IK316 boards.
: Always check the PCB board version printed on the green circuit board inside your device before flashing. Firmware meant for a "V10" board may not work on a "V11" or "V1.0" board even if the external case looks identical. Q6 Android TV Box Product Specification - Manuals.plus
To check your bootloader version, run version in the serial console. If your chosen "best" firmware is not booting, repack it using mkimage or downgrade your bootloader first.
The "best" firmware depends on your goal: maintaining the original look or switching to a more stable Linux-based system.
Wrong firmware can brick the unit. Always verify:
You flashed the wrong firmware. Boot back into FEL mode and flash a known working backup. If that fails, you may need to short the NAND pins (search for "Allwinner FEL short pin" for your specific board).
