This tells me how to update the firmware but it doesn't provide the firmware file.
Hello Lgranlund928,
Above I have provided the links that you can download the instructions for the firmware along with the firmware that you can put onto a USB.
Thank you

Is this firmware for UK or US? I'm in the UK and bought my receiver in 2022. Its missing some menus but it shows I have this firmware R110-0400-2130-0000 which looks newer than the one posted here. Which is the correct one for UK please?
Hello BFG,
That is the current version for the TXSR393 for Europe. What is the menus that you are missing on the unit? Have you tried to reset the receiver to see if the menus would come back?
Thank you
