Not sure if this is a known issue, but after flashing Slim-p5110-4.4.4.build.8.0-OFFICIAL-6930 to my 5113 it didn't have root access. I had to find and flash SuperSU and root binaries afterwards to restore root.
Other than that, smooth sailing...
Or you could use G2 TweaksBox
That is the perfect answer, thank you!
