| Component | Meaning | | :--- | :--- | | | The proprietary Amlogic USB burning tool and the naming convention for its firmware images ( .img or .aml files). | | AML920 | The specific Amlogic system-on-chip (SoC). The AML920 is an older 32-bit chip, often found in low-end HDMI dongles and basic Android 4.4/5.1 boxes. | | 4G | Refers to 4GB of storage (NAND flash memory), not RAM. | | 512M | Refers to 512MB of RAM (DDR3). This is a critical hardware limitation. | | None | In this context, "None" usually indicates no RF (radio frequency) remote or no built-in wireless chip support. It can also imply a stripped-down build without Google Services (SOS build). | | SOS | In firmware circles, "SOS" can mean two things: either a "Save Our Ship" emergency recovery image, or a "Stock OS System" build. More commonly, it denotes a minimal, rescue-level ROM. | | Repack | Signifies that the original firmware file has been modified—either to remove bloatware, change the partition table, or fix a corrupted bootloader. | Why the AML920 Still Haunts Repair Shops The Amlogic AML920 is not a powerful chip by modern standards (think S805 or S905 rumors). It was popular between 2014 and 2017 in budget devices like the MXQ Pro , X96 Mini clones, and generic OTT dongles.
