That’s to be expected, @zkennedy137 is still working on it, and I’m helping him for the research together with @Medelcartelinc as well.

If you would though make a copy of ia.log by booting into stock recovery or stock operating system or the usb installer whichever you can get to without wiping the partition that Tahoe stage 1 is installed to. Open terminal and run this command:

that will save the log as an actual file on your usb flash drive so you can upload it here for me to see and compare with the others.

@zkennedy137 I've already reset everything to the stock system :( sorry
