I've had some issues with the CM7 Toggles that came with NSCollab.
Last night, I tried switching from 2G to 3G. That worked, partly. I couldn't switch back to 3G after that, and I couldn't get any data to send. I tried switching it back on and off from the Toggles, but nothing. After rebooting, not only did 3G not come back on, but I kept getting an Error Message every 2 seconds having something to do with the android.phone not working. So then, I had to flash a backup and got the 3G working again.
Then, earlier today, I tried switching the Mobile Data and Data Sync off, but they also wouldn't come back on, even after rebooting, so I once again had to restore to a backup. I'm pretty new at this, so it could just be me being flat out stupid.
Are the toggles supposed to be this faulty, or is there a different way to turn them back on?
What exactly are Mobile Data and Data Sync?
Is it better to just leave 'em be, and turn just put it in Airplane Mode if needed?
That is a known issue with CM7, my advice would be to wipe data, reflash, then avoid the 2G/3G toggle. That's the only one with that issue so feel free to use the others.

My 3g seems to have stopped working. Wifi works fine, and 3g works for a few seconds during startup, then the icon disappears and there's no 3g. The icon always disappears just before the second media scan (does everyone's phone do two media scans during startup?)
I've tried uninstalling or disabling various apps, but every time, the 3g is disabled at startup. It initially stopped working while using Google Navigation. One second it was working, the next, no data, and it hasn't been back since, bar a few seconds during startup.
I'm in a major metro area with coverage, that's not the issue. I tried resetting the ATT WAP to default. That didn't help.
I'd really rather not do a factory reset of my phone.
Can anyone think of any options? Thank you in advance!
Have you tried toggling it into Airport mode and back out? FWIW a similar thing happens on my Nexus One and Milestone. I will have a data connection then it just goes away. The only way for me to get it back is a reboot, toggling data off then on, or toggle airplane mode. I haven't figured out the cause as it happens across multiple devices and multiple ROMs. It may be my SIM card.
Thanks, I tried that. No dice.
So I got it fixed. I'll post this in the hopes that it might help others.
On a whim I downloaded several apps that toggle 3g. Both APNDroid and Quicksettings showed that APN was on. Toggling them off and on didn't help.
But Smart Bar showed that APN was off. Clicking APN on immediately made the 3g icon appear, and it worked. Thank you Smart Bar!
So, everything works great, except when I activate airplane mode via settings or notification menu, a problem occurs AFTER airplane mode is de-activated. Only the cell network is active, neither edge nor 4g connection is available UNTIL after a reboot. WiFi CAN activate but no cell network DATA available.
I attempted to:
1. search forums and google (similar issues noticed, no solution available)
2. flash stock Rogers radio then re flash CM7, didn't solve
3. Redo APN seetings with different inputs, didn't solve
4. shutdown remove sim, startup no sim, shutdown reinsert sim, startup, didn't solve
5. now on stable (seemingly faster) UCLA3 modem didn't solve
wipe emmc etc., flash SkyIceCream ROM, and then the problem solved!, wipe to factory and wipe cache, flash back to CM7, and the problem returns!
So I'm thinking it's the kernel and/or ROM. My device doesn't FC or SOD atm it seems very stable.
I use airplane mode a lot since I do travel on airplanes quite a bit. I can reboot after airplane mode every time but it's a pain plus sometimes I don't have the time to wait for a reboot literally. Please help, I love the ROM.
Hey brotha - I had a similar problem with mine. When we went on a trip to Phoenix, it took a good 10 minutes or so for the bloody network to come up. I had a bunch of data charges too when it did finally come up... but no description except medianet data charges (sent data not received). My wife's iphone also had some large charged data for sent. I don't know what it was, but the Phoenix market has LTE (obviously nothing to do with the iPhone) - but I figured that because our home network was not the same (4g here) that was a lot of ATT internal configuration fighting going on and it took a while for their systems to parse it out. All speculation and what not, but reboots on my phone wouldn't help until if finally popped open, but I'm betting it's not a device problem, it was a network issue (based on the 60ish meg upload charges we both had our our different phones... and no, we weren't posting airplane bathroom porn to youtube...
I couldn't take it anymore so i flashed nexusmod4 and now i don't have airplane mode problems anymore. So for anyone having this problem on CM7 don't worry you can fix it by flashing another ROM.
I’m currently using AOKP Jellybean 4.1.2, the supposedly stable, reliable milestone version found here: http://forum.xda-developers.com/showthread.php?t=1804223
I'll try to be as thorough as possible in hopes that someone will respond and know what to do. I apologize in advance for being long-winded.
I didn’t have any issues last night when I first flashed the rom. I was able to watch youtube videos using the mobile data. I was also able to turn on wifi to sync some files from my dropbox to my phone, and then turn off the wifi with no issues. However, today after connecting to a wifi network to download a few things and browse the web, I disconnected from the wireless network and the mobile data curiously did not start up again. I DO have cellular service (3-4 bars), and I can make phone calls and check my voicemail by pressing and holding 1 on the keypad, but my mobile data doesn’t work. I looked around for some solutions, and I've since restarted my device several times, tried toggling airplane mode on and off, and did several combinations of reboots with airplane on/off and no dice.
Everytime I use the toggle in the notificaton bar area to turn off wifi, my internet connection goes with it. It says “no internet connection” in the notification background at the bottom of the screen. Once I turn wifi on, I get my internet back and it says “at&t” at the bottom, but I don’t actually get mobile data because apps like “At&t Visual Voicemail” which require mobile data to function don’t work.
I tried flashing the 1.85 radio to see if it would connect to mobile data, and same issue persisted after reboot and dalvik/cache clean. After that failed, I flashed the 2.20 radio + RIL zip files seperately (which is what I understand came with the rom), and still no dice.
For reference, my HTC One X was rooted with 1.73 firmware (I never tried to update it until last night). I did the CID spoof method to unlock my bootloader, and installed the newest version of TWRP on it. I flashed the rom and the gapps package. I used TiBu to restore program settings and a handful of my out of market apps, and the rest of my purchased apps downloaded automatically from the market after connecting with my google account. I had literally just finished reinstalling the last of my apps today via wifi when this issue started to happen.
I'd really prefer a practical method of getting this fixed that doesn't involve starting over with a fresh rom install. Reflashing at this point would be something of a nuisance since I don’t have much free time to begin with. And hey, it took a long time to load up all of my apps just right
However, if there is no other fix that anyone is aware of, I guess I could reflash or in the worst case try a different rom. It’s a shame because the rom otherwise is really smooth and runs great on the phone, in addition to not using a whole lot of resources and having a decent battery life.
Thanks in advance for any suggestions and solutions.
Here is an image of my battery drain screen showing what my mobile data is supposedly doing despite not being able to get a true data connection. Even with my wifi off, there is supposedly medium mobile signal.
And attached is another image of what happens when I turn my wifi off. I pulled the notification pane down and you can see that it says "no internet connection" at the bottom. Also, you can't really see it in that cap, but the mobile data bars behind the notification area are colored white, and there isn't any "H+", "4G", or "LTE" notifiers visible.
Edit: Attached a third image showing the "white" signal bars (i.e. no data connection). Yes, my mobile data is turned on, and I'm obviously not in airplane mode.
I figured it out eventually for anyone interested... Apparently the APN were not set. They existed on the APN list but were not visible due to a glitch in the ROM I guess. I had to add a custom APN and then the other ones suddenly appeared.
Thanks anyway.

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.

I did try that. Nothing seems to be working.
So, I take smoke breaks several times a day and my phone always loses signal in the elevator. This has never been an issue but this week my phone has decided to not resume the data connection when I get back to my desk. It shows it has an LTE connection, I can make calls and send texts but no data. Toggling airplane does not fix it either, I am forced to reboot my phone to get data again. I really don't want to be rebooting my phone 5-6 times a day.
Any ideas for fixes before I go the hard reset route?
Is Titanium backup the best way to go still before doing the hard reset? I however have not rooted this device, so don't think that is even an option right?
Thanks!
