Before updating, it is important to know your current firmware version. Follow these steps:
Downgrading is generally because newer firmware often includes security fixes and hardware support that older versions lack. However, if you experience serious issues, downgrading may be possible by using an older firmware .bin file via the USB method. Some users have succeeded by first installing an “intermediate” version rather than jumping directly from very new to very old. Caution: Downgrading can cause unexpected behavior; always back up your configuration first. dhxvr5104hsi3 firmware
