[Q] No Data Connection - AT&T Samsung Galaxy S II Skyrocket SGH-I727

I have Paranoid Android 2.99 and UCLL3 radio. Recently, I lost my data connection and can't seem to get it back. When my phone is connected to WiFi, it lists the data connection as 4G, but as soon as I disconnect the internet connection I get "No Internet Connection". However, I can still text/make phone calls.
I've tried toggling airplane mode, toggling data, resets, cache wipe/dalvik cache wipe, and reflashing the radio. None of these seem to work.
Does anyone have any ideas that I haven't tried yet? Or should I just reflash and start over?
Thanks y'all!

You should probably try reflashing the whole ROM if nothing else works. But before that, you can try to flash other radios.

I would reflash and see if it's still doing and last I would try a different Rom

So while connected to a wireless network it says you're on 4G? Do you still get the wireless signal icon or just your cell signal? If you have access to your wireless access port, try disconnecting it from the gateway to see if your phone is using the wireless network for data or if there is a very weird connection between the wireless toggle and data toggle. I know it may seem strange, but I have had some weird issues like this. (mine involved CM10 and the CRT off animation only working while wireless is on) See if you can stay connected to your wireless router without it being connected to the isp and see if you can ping google.com. If you can, then we have a starting point. Double check your APN settings on your phone under networks settings and see if you can track down the wap.cingular APN settings to see if you can get 3g at least. AT&T can remove LTE provision and then restore them in hopes to register your device again if all else fails...

Data connect after airplane mode

After going into and out of airplane mode a couple times, my Touch Pro won't connect to data. Tried with the weather tab in TF3D and multiple other programs. I've tried resetting the data connection to avail. Ultimately, I have to reboot the phone to get data back. I am not roaming, I am on the Sprint network when this is happening.

Did you ever get a response to this? I'm having the same issue, and I'm on the new Samsung Infuse 4G, but my issue isn't solved by reboot, I'm only able to go in and tap the apn settings and not change then hit save, and it seems to reset the data, real annoying.

ICS data slow to connect

I am running the Zero rom and it is working great. I am having one issue but not sure if it is ICS related ot not. I am currently in Afghanistan and have edge data service. When I first started using it on GB all I had to do was create a new Access Point and only had to enter "internet" into the APN, no authentication, no proxy etc. So I instaleld ICS then when to their website (etisalat) for the APN setting. They show using a proxy but still no authentication. When I use those settings it shows that I am connected to edge but I get no data down and eventually get an error about not connetcing to the proxy. Anyway, I couldn't get it to work so I used the original APN setting but had to enable "Pap or Chap" authentication. Now it works.
But, the problem I am having is that it takes forwver to get data to connect. I mean when I leave my wifi connection, or go from a place with no cell signal to a place with signal, it takes a long time (5-30 min) for the phone to establish a data connection. I try to open my broswer or other internet programs but they just fail to connect saying no network avaiable. I try turning data on and off etc but it doesn't force it to connect. Eventually I will see the edge data connection icon showing in the top bar and it works again.
Anyone have any idea why it is slow to connect to the data? I never had this problem in GB.
Thanks
Try flashing the radio from this thread, its UCLA3, the best radio in many peoples opinion for speed and connectivity. It is gb based, but that shouldn't be an issue. I was using it with ics for a long time

Thanks, I will give it a try.
Well that didn't seem to help. Any other ideas?
Thanks

[Q] [AT&T] Wifi from hell, help?

So, before rooting, my One X had great Wifi connection. No issues. Now that I'm rooted, I can't connect to wifi to save my life. I tried the wifi fix (not the ROM, but the 3 files instead) and still nothing.
I've tried turning off Mobile Network while wifi was on, turning mobile network on while wifi was on, tried restarting the wifi....
I cannot get a connection to the Store, browsers won't open webpages, it's essentially done for. Yet every other device in my house can access the router just fine (and it's not just here, it's elsewhere.)
Anyone have any ideas how to fix this short of flashing the new ROM (which I can't do from my house since the HTC drivers always fail to install.)
Have you tried running fix permissions to see if there's some sort of error holding things up? The only other thing I could think to do is to do a factory restore of the phone, unfortunately...

[Q] Rogers Galaxy SII: No Data Connection

I have the Rogers Samsung Galaxy SII running CyanogenMod 9. A couple of days ago I rebooted my phone and for some reason it got stuck on the CM boot screen. I tried unplugging the battery overnight but it still was just stuck on boot. So I wound up re-flashing the phone and installing CM9 again. Now I cannot get a data connection at all. Wi-fi works fine and I'm able to make and receive calls but for whatever reason it will just not connect to LTE/GSM.
I re-flashed the phone again, using a slightly older release of CM9. Still not connecting.
I have tried about 3 or 4 different modems. When I flash a new modem and reboot the phone, it will connect to data for about 5 mins. I will see the data connection flip between 3G and H+ numerous times and then the data connection will drop and I cannot get it back.
I've set my APN settings (ltemobile.apn) and I've gone into the phone settings via *#*#4636#*#* and tried various settings in there (LTE only, LTE/GSM pref, etc.) Still not connecting.
Any ideas? I feel like I've tried everything at this point.

[Q] Need help with connectivity issues. DESPERATE

Hey guys, quick background. I bricked my SGS3 and had to have it replaced. I think I got a refurb phone because from day one I keep having the same issue. First day I got the replacement phone I rooted it and flashed CleanROM 5.0. Everything was peachy until I noticed that I have no 4G or 3G service. In fact, I had no data connectivity at all. My phone can make calls, receive texts no problem, won't connect to internet. If I restart the phone, I have 4G right away. After a few minutes, the 4G icon is on, but the phone won't has no data connection (when I say data connection I mean it will not go online, no internet, no android market, still have voice and txts). If I attempt to go on internet, I get a message saying "No Signal Found For Mobile Networks". I have installed Network Signal Info and right after a restart it says 4G LTE, data connected, upload+download activity. After a few minutes, it says 4G LTE, data connected, after a little while, it will switch to EHRPD, with data "connecting". Also, in the System tab, it will tell me my IEMI and version of JB running, next to "Radio", it says "unknow". WiFi works perfectly btw. My IEMI is perfectly fine,
I had it backed up. My phone number is still there.
Here is what I had tried so far: Switching into and out of Airplane mode, different programs that reset mobile connection, flashed different custom ROMs, flashed the stock kernel, flashed 3 or 4 verizon Modems, Data wipe, cache, Dalvik wipe, Odin'ed back to stock 4.0.1 ICS and had upgraded it to 4.1.1 via verizon software update, changed the SIM card, and reprovisioned the phone with that *3767*whatever the hell code. I'm out ideas.
If anyone has any other idea that I can try before I take it back to Verizon, please, let me know.

Did you go into your mobile data settings to make sure you're on CDMA/LTE? If not I would select and reboot the phone and see if the problem persists. I don't know if you have tried this but it's worth a shot.
I'm having literally the same exact problem with my mom's S3 except for it's not rooted, complete with 'download + upload activity' and 'unknown' radio. I've yet to find anything in my search, but if I do I'll post it here.
