Root not working on ChromeOS 74

[AraDevs]

Hi! Your work here is amazing! sadly I'm unable to root a chromebook with ChromeOS 74 installed, I've managed to run all the first script flawlessly, however, the second script doesn't recognize the SU.... I don't know if is a issue related to android 9 and super su not getting along, maybe if we use Magisk instead of super su all the android versions could be covered?

Thanks for reading

Flawlessly? I run the first one in developer mode and its completely locked out..

I have the exact same issue here. Even tried setting up the file directories which the script tries to make manually. Still the same output. And still 02SEPatch.sh says no Su found. :/
Also kinda agree on using Magisk simply because it's just gotten so much better than SuperSU with the systemless interface, repos etc. I have magisk on my phones and tablet and I'd love to see it on my chromebook.

You have to download and extract supersu into the downloads folder, however don't waste your time there, if you have one of the newest versions of chromeos it's more likely that isn't going to work
