I was trying to update my acer C720p laptop’s firmware from 4.14 to the current one (4.22.2) but it got stuck for an hour on (Error parsing manifest…)
specs:
intel celereon 2955u
2gb ram
32gb ssd
firmware: MrChromebox - 4.14
OS: Windows 11 home
codename: Peppy

Most likely, you’ll need to boot a Linux live USB and update that way.

ok i am running ubuntu from a usb what should i type in the terminal?

cd; curl -LO mrchromebox.tech/firmware-util.sh && sudo bash firmware-util.sh
