Modification of MrChromebox's script to support flashing RW_LEGACY on EOL devices.
If you encounter any issues with running RW_LEGACY on your chromebook, you will recieve NO support from either MrChromebox or me.
Run
cd; curl -LO https://raw.githubusercontent.com/OtterCodes101/rw_legacy-eol/master/firmware-util.sh && sudo bash firmware-util.sh
to use the script.
