This procedure assumes you are using an Amlogic-based STB with USB Burning Tool. Adjust for Rockchip (RKDevTool) or HiSilicon (Hitool) if necessary.

Boot the STB into fastboot and run:

fastboot getvar erom-version

If the output is older than 2.1.0l (e.g., 1.8.2 or 2.0.3), the upgrade is applicable.


Boot into fastboot again and run:

fastboot getvar erom-version

Expected output: erom-version: 2.1.0l


For developers, the new release enables verbose UART debugging over triple baud rates (115200, 230400, 460800), making root-cause analysis of boot failures significantly easier.
