I have a Nexus 9 with SlimRoms and a broken TWRP recovery that won't start, so I can't factory reset, clear cache, etc..
So I dealt with that.
A few weeks later, the fonts on my Nexus 9 because big. I was able to fix it. But then I realized that the Interface settings were gone. The only way I can access the System UI Tuner is through Nova Launcher's activities option.
The home button stopped working, and the recents stopped working. I can't access Users or Developer Options. If I switch to the Guest account, the home and recents work, but apps are frozen. Trying to create a new user would force the tablet to switch back to the main user.
Other people have gotten this issue, but not on the Nexus 9, usually it's on a Galaxy, so no luck for me.
There's no troubleshooting kind of forum on this, the closest thing I could find, was the general discussion.
I have installed SlimRoms clean, no dirty flashing at all.
Any fix without reinstalling the entire ROM again?
