Uh oh, That doesn't sound so healthy.
The 2D logo, From my experience, is used when the unit is cold booting - similarly to the "SAMSUNG" splash on android phones from a certain manufacturer
- This logo would be displayed for the initial kernel load (Note this is speculation from experience of the HU & Android / Linux systems)
The 3D logo is ususally from a warm boot; as you would get when turning on the car - The unit is in a sleep state, rather than full shutdown.
The 10 Second reset would be my first port of call, as you've already tried:- It could be worth disconnecting the battery (Having shut down the unit first!), a-la Smartphone battery pull
and reconnecting after a brief wait to ensure the unit is fully power cycled.
I've had a few similar scares, and usually they can be dealt with by power cycling / panic pressing the power button
and letting it do it's thing - Try giving it a couple of cycles, though I imagine you've tried this already.
I'll do some quick looking, but as far as I know, you'll only get the honda diagnostics screen once booted in - I don't think there is access to a boot debug (To memory, will check now)
