Chromebox stuck on black screen with logo
I upgraded yesterday my Acer CXI3 from stable to newest stable. It got stuck on a black screen with white ChromeOS logo.
I can recover with beta from https://cros.download/recovery/fizz
But, when it updates, the same happens (it gets stuck). I repeated it several times, not allowing immediate upgrade, and switching build to stable or to dev: same happens after OS update.
Finally, I recovered with LTC. This works okay. That is ChromeOS version 150.
Also, I have a Minisforum mini-PC (Venus series UN100C) with ChromeOS Flex. Same story. Except that sticking a USB stick inside one of its ports, allows ChromeOS Flex to boot.
In the end, I'm glad that I learned to use the LTC version: updates are really fast, and Android apps download really fast.
