Upload your boot.img patched by SuperSU and I'll take a quick lookI got a problem with SuperSU after flashing any kernel. I tried TGPKernel and same result.
I flash the kernel then flash 2.79 SuperSU straight after. Root access is working for apps that were previously allowed but any new apps and the root prompt doesn't show.
Like before flashing kernel AdAway had root access. After flash it still has access, but any app that didn't have access before can't request since the request doesn't show.
Running Renovate Edge r130, but it's the same result on Helios 7.9.0 and ambasadii 11.0.
