[Q] Can't Enable Unknown Sources
Hello: I have an AT&T I337 that until 2 days ago had stock ROM on it. I didn't like the fact that AT&T blocked my ability to 1) tether, and 2) sideload so after about 1 1/2 years I finally decided to root and flash a ROM that would allow me to do these things. I downgraded from NB1 to MK2, rooted with saferoot, installed safestrap, and installed Deadly Venom's v3.0.2 NC1 KitKat ROM. Since there are some outstanding instructions in the AT&T GS4 forum I was able to do all this relatively easily (and I'm pretty much a NOOB) and I'm really happy with the ROM so far. The Wi-Fi Hotspot capabilities seem to work well; the only problem is that I still can't sideload. The "Unknown sources" option under "Security" in settings is greyed out and unchecked (so are "Wait for debugger" and "Verify apps via USB," under "Developer options," but I don't think I need those items for anything). Does anyone else have this problem? Or more importantly, does anyone know how to enable "Unknown sources" so I can install apps from the Amazon Appstore, etc.? I thought for sure that rooting would be the solution, if not the custom ROM. I even tried using the AndroidCentral Sideload Wonder Machine v1.2 that someone mentioned would install apk's regardless of the phone's security settings -- it didn't. Any assistance would be greatly appreciated. Thanks...
