Device is Acer C720P (PEPPY). Per the FAQ at Frequently Asked Questions | MrChromebox.tech (Use Find In Page in your browser, and search for VT2):
The script says I must run it from VT2 terminal on ChromeOS R117+ - how do I do that?
*Starting with ChromeOS R117, Google removed sudo from the main shell, so the script must be run from a VT2 terminal:
- At the ChromeOS login screen (not logged in), press [CTRL+ALT+F2] (F2 is the right arrow key)
- Login as chronos (no password needed)
- Run the script: cd; curl -LOf https://mrchromebox.tech/firmware-util.sh && sudo bash firmware-util.sh
You cannot run the script from a Crosh shell ([CTRL+ALT+T]) or from a Crostini/Penguin terminal.
Right! The first words in the FAQ entry are: Starting with ChromeOS R117
PEPPY is running ChromeOS 76.0 3809 136 (Official Build) (64-bit). Way earlier than R117.
The [CTRL+ALT+F2] doesn’t do anything. I don’t think it existed in PEPPY’s heyday.
I tried using the [CTRL+ALT+T] terminal to download the script, and run it. However, curl was not a valid command, and neither was sudo.
What terminal was used to download and run the script to flash Coreboot on Chromebooks, before R117?
