Their new website is a chaos.
Yeah wtf. All their old links are broken, plus they used to have multiple old firmware versions available for download, in case there was a problem and you wanted to roll back. Now they only seem to offer the latest (3.03). But most importantly, I can no longer find instructions on HOW to update the firmware. I haven't done it for a few months and I forgot how. Googling doesn't turn anything up. Anyone have the instructions saved, or know of a link where they're still posted?
I used the wayback machine from archive.org (

Please read and follow the steps below carefully. You may want to print them before upgrading firmware.
Sound Devices recommends saving a setup file prior to loading new firmware.
Prepare to Update
Download the MixPre firmware file MixPre_2.21.zip using the link below.
From the zip archive, extract the file within named MixPre_2.21.prg file. Copy this .prg file to the root level (not within a folder) of an SD memory card that has already been formatted by the MixPre recorder.
Power the MixPre via USB-C to external DC power or via "fully charged" batteries. Do not perform the update with low batteries or unstable power sources.
Insert the SD card with the .prg file.
Power on the MixPre.
Navigate to System > Update Firmware and follow the on-screen instructions.
When the update is complete the recorder will power cycle itself. The version number MixPre_2.21 will be displayed briefly on the splash screen while booting up. A message box appears "Firmware updated successfully Version:MixPre_2.21". Tap "OK". Please note any changes or additions to the main Menu (if applicable). Consult product documentation for details.
