go back system, disable developer options, you really don't really need those to stay enabled.

Yes. That's what I am trying to find 😬
read my last comment
Settings > About Phone > Tap the Build Number a bunch to enable developer options.
Then they'll be under System, where you can disable OEM unlocking. You may also need to lock the bootloader in fastboot, I can't remember.
If she has followed the install guide properly and her phone shows a yellow "Your phone is booting an alternative operating system" page, then her bootloader is locked already. Fortunately this is already in the instructions 😃
Well. I thinkji manually had to do that. Because I received an error from the instruction page.
And now that I ent back to developer options the OEM unlocking was enabled.
I think I got it now. Might have to figure out how to verify with the boot key hash. 👀
Then as long as you get a YELLOW boot screen then you should be fine... 😅
The verifying boot key hash is matching the hash that appears on the boot screen with the one on the list in the install page. Reboot the device and you'll see it at the bottom 😃
I think we are good. First 4 and last 4 are the same
