Samsung TV & Audio HW-S800B Ultra Slim 3.0 Channel 360 Watt Soundbar with Dolby Atmos and Bluetooth FIRMWARE UPDATE FAIL Error Fix: Over-the-Air Firmware Update Failed

Error code FIRMWARE UPDATE FAIL on the Samsung TV & Audio HW-S800B Ultra Slim 3.0 Channel 360 Watt Soundbar with Dolby Atmos and Bluetooth means: Over-the-Air Firmware Update Failed. Firmware update via Wi-Fi / SmartThings fails to download or install. For OTA: ensure stable Wi-Fi connection, keep soundbar powered on during update, don't press any buttons during update. If OTA fails repeatedly: download firmware manually from samsung.com/support → search model number → Software & Drivers → download latest firmware → extract to FAT32 USB drive root directory → insert USB into soundbar → update starts automatically. CRITICAL: never unplug soundbar during firmware update. If update bricked the soundbar (stuck on "UPDATE" or no display), try USB recovery: insert USB with firmware, unplug/replug soundbar while USB is inserted. Contact Samsung support if USB recovery fails.
