Ok so I was upgrading the firmware on my Gen 1 from the original 1.0 to the latest 1.03.01 and I ran into an issue that the firmware upgrade got stuck at 0% and wouldn’t go any further.
I had tried a reset and re-down loading the firmware still no luck.
I actually found a hint to the solution on the board but I thought I’d document it in a message to make the solution easier to find.
My issue was caused by my USB drive being too big… I was using a 4GB fat32. I copied the firmware onto a smaller drive (the new drive was 512MB but I think 1GB would also work)
I powered off the WD media player even though it said DO NOT, swapped the USB drive for the smaller one and turned it on… When it powered up it found the smaller USB drive rebooted then installed the firmware… No ill effects.
