Not here unfortunately. I've quit messing with it for the time being because without debug logs and ways to figure things out it is impossible for me to continue.
I've tried starting Zygote with strace parameters but it doesn't finish booting, it hangs at the black screen. I thought maybe strace was so busy writing logs that it was just slowing it way down, but nope I didn't find any log anywhere after rebooting.
Unless someone wants to give me pointers about getting a boot log or some kind of verbose log, there's not much I can do unfortunately until I can think up enough more ideas to be motivated enough to play with it again.
