My Acer 14 Chromebook that I got for free from Acer and Chrome years ago entered into AUE. (Auto Update Expiration) This made me the sad, as it is a nice little laptop for carrying around for web surfing. I started going down the rabbit hole of third party firmware. I had used Brunch Framework on Intel laptops, but didn’t see anything specifically for the Acer 14. But then I looked closer at the Auto part of AUE. Could I manually update this? I saw that there was 114 versions for the Loki family brand on the supported site. So I loaded up the Chromebook Recovery Utility Extension on my regular windows machine, created a new media USB for it, installed and look at that fully updated. So you can’t auto update, but you can manually update. So keep using those Chromebooks, and keep them up to date.
