This information is collected over time by my rooted devices and stored in a database. There might be firmware older than this, but it is not listed here as I did not own a particular device at that time. There is no guarantee for accuracy of this information, as the availability of firmware might be device specific and region specific. Sometimes I don't have enough devices to cover all regions.
