@Kielligzind2 yes you can, someone said about slow and low RAM. But if you have a tweak kernel exactly. Nexus 7 2012 wifi will work out of the box, and I knew the tweak of kernel
I own one also but since I also have own newer Nexus devices I will focus on using them.
Given the age of the 2012 devices I can't imaging much reason to open any new development and any system images that you do find will without doubt be full of bugs.
