Accidentally enabled OS verification with SeaBIOS/RW_LEGACY, will the break anything in my Chromebook?

Accidentally enabled OS verification with SeaBIOS/RW_LEGACY, will the break anything in my Chromebook? So far nothing seems broken, but is there anything i should know of? but also when I re-enable dev mode, can I just press ctrl+L & SeaBIOS will still work, or do I have to re-install it?

well, it erased everything under ChromeOS. You will likely have to re-enable the dev_boot_legacy crossystem flag in order to boot legacy boot mode.

Ah ok, but will i need to reinstall SeaBIOS?

not unless you performed a USB recovery. but you can always just reinstall it to be safe, there’s no harm, and it will set the flags as well

Ah ok then, thanks. Ill see if its still installed, if not ill reinstall
