First let me start with the phone: AT&T Galaxy S II running 4.1.1 SuperNexus Rom Build 4-20121007. Kernel is 3.01.15-CM-g3802d32 faryaa kernel. Baseband 1777UCLE5 Everything was working fine. I've been running SuperNexus for about a month. The only initial problem I had was that the baseband was not working upon startup and I had to put a new baseband in for it to work, got that fixed and been flying smooth for a month with no issues. Today...suddenly it stopped being so smooth. Let me clarify: - I can make outbound calls and hear just fine (couldn't do that when baseband was wrong) - I can recieve and send text messages - I show a full reception bar up top with 3g, the signal bar is grey. That may mean something or it may just be the color theme for this rom. I didn't really pay attention before the issue. - Network info: AT&T network, Signal Strength -83 dBm 15asu, Mobile Netowrk type UMTS:3 HPSA+ :15, Service state is 'in service', Mobile Network Status 'connected' I was literally in the middle of surfing the internet and pulled up a browser for a webpage, suddenly it hung in terms of loading the website. It did nothing for about ten minutes. I then found that all apps that use data do not work. They attempt to load but give errors. I rebooted the phone several times, shut it down fully several times, removed the battery and sim card, replaced and restarted. None of that worked. I made a call out to a friend and he could hear me and I him very clearly, call dialed out and connected without issues. Text messages come and go just fine. The only thing I can think of is that they turned on the 4g signal in my area, or near it today and maybe there's an issue there. Please help. Thanks in advance.
