2018 Fire TV Stick 4K Firmware Entry Appears After 320 Days
FTVDB lists Fire OS 6.7.1.1 (NS6711/5908) for the 2018 Fire TV Stick 4K, 320 days after the previous package date.
A new firmware entry has appeared for the 2018 Fire TV Stick 4K.
The FTVDB firmware page for Fire TV Stick 4K - 1st Gen (2018) now lists Fire OS 6.7.1.1 (NS6711/5908), code 11644900484, with an uploaded date of March 23, 2026. The previous listed package for the same device is Fire OS 6.7.1.1 (NS6711/5866), code 11644889732, uploaded May 7, 2025.
That is a 320-day gap between uploaded package dates for the same model family.
Amazon has not published release notes for this package, so there is no confirmed changelog. The confirmed news is the metadata: the same Fire OS version string, a newer build label, a newer code, and a 2026 package for a 2018 device.
Amazon’s current Fire TV software security updates page lists the Fire TV Stick 4K (1st Generation) as receiving software security updates at least through December 31, 2029. That means this entry should be treated as late-life firmware activity for a supported device, not as an update after support ended.
