Nope and nope. I purposely stopped all play store updates and tried to only download busybox and update supersu. It said they were downloading, but just continued endlessly. And performance control is just endlessly checking for root, there is no prompt to allow or deny it from root access. Also, when I open supersu, PerfCtrl is not listed as granted nor denied. I tried em both for about 1/2 an hr w/o results, so I doubt waiting is my key to success here. Lastly, neither explains why there is no phone signal (data), unless that's part of the performance control setup. Everything works on stock so it's not the phone, and my wifi is speedy, so that's not the issue either.
