[1] END OF LIFE / END OF SALE: Devices get this flag if we see that they did not receive firmware updates for a long time or are not available anymore in specific regions. Same applies if the model was replaced with a new one.

<-- Back to the overview


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.
