Despite these benefits, updating the NB4540 requires caution. The process demands a stable power supply and a consistent internet connection. Interrupting the update—by unplugging the soundbar or losing Wi-Fi signal—can "brick" the device, rendering it inoperable. This fragility often deters users, but the risk is minimal when proper procedures are followed. LG typically advises users to be patient, as the update can take several minutes, and to avoid using the soundbar during the process.
