Bittboy v3 not booting with 2.0.0

[novhack]

Hi!
I tried beta and nightly and my v3 doesn't seem to boot at all - it just shows a black screen (after a while the "We understand.(...)" and "Formatting swap P3 partition" appears but there is no way how to interact with it.
v1.3.3 works fine and I've seen somebody else on Discord having the same issue with their v3 console.
Is there something I could do to help to resolve this issue?

I managed to make it boot by renaming firstboot file in BOOT partition to firstboot-OLD. I guess skipping the whole setup.
Buttons didn't work but adding miyooctl -k 7 to the end of normalboot.custom.sh fixed that.
Screen is not flipped and seems to work normally.
I did these changes on today's nightly build nightly.link/MiyooCFW/buildroot/workflows/build/master
