Hi, I have a PWD Mk II w Bridge that I haven’t used in a while. I’m now trying to update the firmware (2.4.4 and bridge 2.15) and I’m having trouble getting the PWD to switch into firmware update mode. Current firmware is 2.0.2 (bootloader 1.02, USB 1.03). I have two PS Audio supplied 2GB Sandisk FAT16 cards, one with 2.2.0 and one with 2.4.4. Neither SD card (inserted correctly) triggers a firmware update. I’ve ready quite a few posts here on correct approach and believe I’m doing all the right stuff (unplugging other devices including power, re-attaching only the power cord). I’ve held down the front logo switch and it goes into screen calibration. I can touch the logo on the screen and it goes into the version screen. But no firmware loader. Was there a different method to trigger this back in the days of 2.0.2?
