I too have successfully rolled back to 52!

The process I followed was as follows

  1. Download 52 firmware from B50 Firmware Version Update 52-452f344c
  2. Put firmware on a FAT formatted USB drive. I used a very old Lexar JumpDrive 2.0 pro (256MB)
  3. Connect the hdmi cable to the B50 and to a suitable device, I used a Chromebook and a dock.
  4. Once connected the lights on the B50 stop flashing and I was able to select the BT input on the amp by using the volume control once connected via Bluetooth I was able to select USB and I was immediately notified about an available upgrade.
  5. Clicked the upgrade and within seconds B50 was restorted.

Thank you @Topher52 and @arboeh for having the smarts to try the HDMI port! You have made my weekend!
