No Internet, even over working wifi

I just got this phone, really excited when I got it working on my plan of course, rooted it but planned on keeping stock rom just to test out and have some fun while keeping it cool. Hours later, after an RUU reflash, update, and flash over to Harmonia 3.17, no matter what I've done, no matter what step along the way, internet doesn't work on anything but syncing my account. I've successfully connected it to my home wifi (with which I'm typing this on my laptop, so no issues there), but not wifi nor 3G gives me internet, can't connect to the play store, can't browse the web, but get texts just fine. Is there any way I can fix this without doing the "Fix Everything Evo3d change" thread? I'm trying to keep my system S-ON, so that's kinda a hope to not do.

If I can get any help in the next 8-12 hours, I'd be eternally grateful.

 

I wiped everything. I'm using TWRP 2.2 touch, and I cache/dalvik, then factory reset, then system wiped, then installed Harmonia, mostly just to make sure it wasn't an OFW issue. I did figure out right after posting last night that it seems to be the wifi, not the 3g that's having issues. I gave it a few reboots to give it a check, and 3g seems to work alright as it usually did for my LGOV, but wifi makes all data just cease to work, EVEN with a working wifi network (long run-on sentence, but it makes sense). I didn't check the MD5Sums, just because I'm not sure how to do that.

I'm seeing if I can get a replacement from a local store because I also noticed a dead pixel on the phone, but truly if I get it working I shouldn't notice it at all once I get to using the phone working, so I'll update this afternoon after checking.

 

Well, the problems seemed to iron themselves out actually, wifi is working at my friend's house, so is 3G, I'll probably just get the 4ext app from the Play store and flash that.
