On February 24, 2025, Samsung released a software update for its Q900D, Q910D, Q990D, and Q800D soundbars. By March 10, it became available for manual download from the official website, and on March 13, devices began receiving it automatically via Wi-Fi for users who had enabled updates in the SmartThings app.
However, soundbars that received the update over a wireless network experienced a critical failure. The devices froze completely, lost their Wi-Fi connection, and stopped responding even to attempts to reset them to factory settings. In contrast, soundbars updated manually via the USB service port installed the same update without issues and continued to function normally.
What caused the Samsung soundbar update failure
This isn’t the first time a Samsung update has led to serious problems—a previous faulty firmware release rendered Blu-ray players unusable. In this case, the most likely cause is an incorrect update assignment.
Before installing new software, the soundbar sends its model and serial number to Samsung’s servers, which determine the appropriate firmware version. Under normal conditions, this process ensures compatibility. However, during the automatic update process, a critical error apparently occurred, resulting in the devices receiving the wrong firmware and ceasing to respond to any actions.
The first reports of this issue emerged on Thursday, March 13. It took Samsung two days to fully assess the scope of the problem and three days to disable automatic updates and remove the faulty file from the website. By that point, many soundbars had already downloaded and installed the update in standby mode. As a result, when users turned on their TVs, they found that their soundbars no longer worked.
Fixing soundbar update error
Currently, the affected soundbars cannot be restored using a standard update. The only possible solution is a complete firmware reinstallation at a service center. Since the soundbar does not respond to standard commands, restoration requires direct intervention—either reflashing the memory or replacing the memory chip.
Initially, Samsung began recalling defective devices. However, once it became clear that the problem was global in nature and affected tens, if not hundreds, of thousands of devices, the company suspended the acceptance of devices at service centers while it sought a simpler solution. Repairs later resumed.
