Help AT&T Note 2 (i317) NFC / SBeam / Wifi not working.

[100n3y]

Lemme first drill down the facts:

Was on 4.3 stock rooted. NFC and SBeam stopped working a few months ago. No biggie, but I'm trying to sell it now and want everything to work for the buyer. When I would click Sbeam or NFC...the switch SOMETIMES toggles, but never turns green. Most of the time it'll flip on and off rapidly or not flip on at all. Wifi worked fine.

Currently on 4.4.2 Stock (I know I shouldn't have, but the ship has sailed) w/ NE5 baseband. Kernel 3.0.31-1728680

I've tried i317-cwm-ucucne5-rooted-deodex...same issues. No NFC, SBeam. Wifi connects successfully, but can only access about 256kb worth of data before it just stops. Stays connected...just no data being transferred.

I've been messing with this for 3-4 days now so me posting here was/is my last resort. I'm at a complete loss. There's lots of info tip-toeing around my issue, but nothing seems to hit. Please let me know if there's anything else I can do to help you help me and thanks, in advance, for any assistance.

i have same problem when connecting wifi to my xperia c. there's 2 thing..
1:authentication problem.
2:wifi connected but cannot browse the internet.
solution to:
no 1: press and hold the wifi name in the wifi setting, and modify the network. i dont know how other phone works, but try to modify it.
2: clear all the cache files, and some apps data that u can retrieve back such as facebook (takes a lot of ur memory spaces) messanger, and browser like chrome and others.

my wifi problem fixed when i do this. try it out. hope it'll help.

Preesh the help Asyar, but I already tried regular network troubleshooting. Wifi worked perfectly until the 4.4 upgrade. It has to be something else regarding that. I'm more interested in why Sbeam and NFC fail to turn on. Could it be a hardware issue? I am using the stock samsung battery and nfc back so it's not an interference issue.
