Explain what the expected result was and what happened instead.
The "Hold Lock, Menu and Left buttons" method of booting to data disk mode seems to be not working after the most recent OS update 1.12.3
Not sure if this was intentional, but accessing data disk mode through settings is a bit cumbersome. I'm hooking up to Windows 10.
When I hold the button combination while connected via USB, nothing happens. Have held for upwards of 15 secs on a try.
