My pleasure it actually has the April 2019 security patches so you will still be pretty secure and safe to use this rom without having to worry about your device or accounts getting hacked or tampered with. Hope this helps and if you plan on testing the rom make sure to use my gapps so you don't run into problems installing gapps

If you have any suggestions for other nougat based roms for grouper let me know via pm or here on this thread so i can make them for everyone. I plan on making a aicp nougat build for grouper next. I also plan on making aosip nougat for grouper also. I don't want to make tilapia builds unfortunately since i dont have that much free time anymore. Cheers!

Congratulations @JT1510365 !

We have another working and responsive ROM for the grouper Nexus 7, that's 3 now. We're so lucky to have the choice for our ageing device! I followed your instructions and installed the ROM no problems. It's smooth and functional, I would recommend it. Well done and thank you so much for building it

Your welcome and my pleasure! My only issue with the ROM was chrome wasn't loading webpages at all so i downloaded this version from apk mirror instead and now it loads webpages just fine. Another issue i saw was substratum won't apply dark mode for some reason. Other than that i have no other issues with the ROM.

I get setup wizard has stopped working. My Install

Format Data
Installed rom
Installed bean gapps linked in first post.
Reboot (I did not installe Magisk)

I followed this guide to give permissions to Setup Wizard: https://forum.xda-developers.com/cro...opped-t3274219

But I get the same error. Any ideas what I'm doing wrong?

Edit
Did above again but also installed Magisk 20.4. Then it worked and no issues with setup wizard 👍

Glad you got it working. I have uploaded an updated version of my gapps package that does not include the setup wizard so you dont have to worry about it. You actually don't need the setup wizard and it just takes up more space in system. But your fine with your current setup i guess but if anyone has anymore trouble just download the new gapps i made and then do a full clean flash rom install again. Download is below.

Just installed this and it's working smoothly - thanks!
I see there's a theme option, but only a choice between white and black. Is it possible to use a custom colour, or just a dark theme (rather than full black)?

What's VanirAOSP and how does it differ to Viper? It's great to have options!
