Coolstar Organisation wants to do his Windows thang with one of the Broadwell Chromebooks, so I'm trying to build a working ROM with chromium.googlesource.com/chromiumos/third_party/coreboot/+/firmware-yuna-6301.59.B to give him a hand. Luckily USB debug works with this, so here is what I'm getting. What could I do next?
Do you happen to know if the hang happens at the same spot when using serial?
I don't. What do you mean by "using serial"? Serial console? I can tell you that if USB debug isn't enabled, it will hang/lock almost immediately after pressing the power button, and require a long-press to switch off. If using USB debug, it switches itself off and terminates the console at the end of the log. The only other thing I notice is that on a "normal" boot using the backup, the next bit of log is vboot related which I am not using i.e.

Incidentally, if I flash back my backup, it goes into recovery mode now every time I boot (flags are 0x489), I've tried pulling the battery to no avail. If anyone has a trick to get around that, I'd appreciate it, as the Acer is my main machine.
What is the recovery reason? (<TAB> at the recovery screen)
I managed to get around that one by flashing a shellball ROM and then flashing back the backup internally. Next time I do it I'll press the TAB key.
