Amlogic Burning Tool

Amlogic USB Burning Tool or Amlogic, almost always written AMLogic is an American technology company that was initially founded as Amlogic Inc. In the US and is primarily focused on developing and selling integrated circuits for SoC (System on Chip). Amlogic’s USB Burning Tool is a Windows based tool used to upgrade devices based on Amlogic processors over USB. Most devices now implement OTA firmware updates, so in most cases it is not necessary, but if your device has problem to boot, or want to update to a beta software it is often required, although now it is possible to use a micro SD card with Burn Card Maker.
