The MSD338 chipset with 512MB of RAM was obsolete in 2018. No firmware update can add more RAM or improve the GPU. Even after a successful update, expect sluggish menu navigation.

While holding the button, plug the power cord back into the outlet.

: Ensure the file name exactly matches what the board expects. Generic boards often require the file to be named all_upgrade_msd338_512m.bin Board Variants
