How To Create A Chrome OS Recovery USB Drive With A Linux Device (https://www.youtube.com/watch?v=KpMswyiQM04)

This video shows how to use Linux to create a USB as the Chromebook Recovery Tool Google Chrome Extension is not compatible
on Linux

Browse to https://support.google.com/chromebook/answer/1080595?hl=en#zippy=%2Cuse-a-linux-computer and download
https://dl.google.com/dl/edgedl/chromeos/recovery/linux_recovery.sh

This tool gives you 500+ recovery images to choose from.
Unfortunately ChromeOS Flex is not one of them
After some investigation and browsing https://Chrome100.dev it appears the ChromeOS Flex board is name reven
The Recovery Images are located here https://chrome100.dev/board/reven

The linux_recovery.sh downloads a conf file with the list of boards in it.
However we can also pass a local config url ( for debugging purposes )

Run the following commands

cd /tmp

wget https://gist.githubusercontent.com/trevd/f26d66f5c54dd2275e17abda2593b1e0/raw/38a0c5b29d498dcf97679410563d02bd8ab279fb/flex.conf

wget https://dl.google.com/dl/edgedl/chromeos/recovery/linux_recovery.sh

sudo bash https://dl.google.com/dl/edgedl/chromeos/recovery/linux_recovery.sh --config file:///tmp/flex.conf

This will give you only 1 recovery image to choose from and will create the ChromeOS Flex recovery image USB Drive

Thank You and Good Night!
