[Google Pixel 2 XL Guides, News, & Discussion] ScottIsMyName:
Hmm, good suggestion, but that didn't help....still boots okay. The weird thing is that even after changing those in prop.default (which is symlinked from default.prop), after i boot up, both props I changed still show as 1.

2|taimen:/ $ getprop | grep secure
[ro.adb.secure]: [1]
[ro.secure]: [1]

I saw your edit and set debuggable to 1 and still no difference.

Here is the contents of default.prop by the way:
