No Data (3g/4g). Root related?

I just got off the phone with Verizon. My Rezound has 4G, but the Droid4 has no data (but does have voice, and Wifi works). They had me do the following:
- Reboot the phone (did that before calling)
- Pull and re-seat SIM card and SD card
- Clear Browser app data and cache (morons)
- Toggle airplane mode
- Toggle Data roaming
- Safe mode
I also tried toggling CDMA/LTE with CDMA-only on my own, and cleared the cache partition in Recovery.
Nothing I do can get data back. Also, after a reboot none of the text messages she received today are still in the app. Since my phone is working, a network outage doesn't seem likely. The D4 is rooted but no custom ROM.

Thanks, but it didn't change anything. VZW suggested I try a factory reset, will it mess up root? I don't mind rerunnung the script if necessary but I want to make sure it won't break the phone.
One other question is because I am new to SIM cards, could a bad SIM work with voice but not data?
EDIT: Doesn't the 3G still go over CDMA, so shouldn't I have 3g at least, even with a bad SIM?

I have very off and on data. I go to airplane mode and back and sometimes it fixes it. Could b circumstance..I am on my second d4 and it was so bad I had to get on wifi to setup and sync everything on this new replacement ...I'm rooted as well but obviously I wasn't when I did setup and it was bad. I don't think root is to blame. Could b the sim. We r in a good coverage area supposedly.

Voice is still over CDMA/3G, LTE is for data only, and is what the SIM is for.

On your phone do you have the lte logo pop up?
I have been having issues with my d4 which is rooted as well. I have figured out for some reason the APN that controls the internet keeps dropping out however the IMS APN stays connected. When that happens the lte logo stays up but turns white and when the internet APN is connected it turns blue.

There is no signal bar for 3g or LTE. unless you refer to a different symbol?

Some of the Razrs have the same problem. Probably you will need a phone swap, would try factory reset first.

Did you do a restore from titanium backup? If so was it a restore of EVERYTHING? Cause I did that when I got my droid 4 and I had no data or anything once the restore finished. I had to do a full blown factory reset then everything was good again.

I assume you've already tried settings->data manager->data enabled, checked?
My D4 decided to turn this feature off on its own yesterday. I use the Smart Actions app to disable cell data when using a wifi connection and this configuration might have caused some kind of hiccup and not allowed the cell data to come back on when a wifi connection was out of range. I had to hunt around a little after trying most of the stuff you mention above only to find the data enabled, not checked. Simply turned it on and LTE came back instantly.
Good luck.

Verizon tech support told me this is a known software issue with the Droid 4 and advised me to keep the WiFi turned off when I didn't need it. They also said a fix was on the way around the end of July. (This now appears to be ICS, which looks like it might be out very soon.)
From my own use, WiFi appears to be responsible. I can lose my data connection when WiFi is turned on even when I'm not connected just like I was told.
I can also lose data when Notify Me is enabled in settings. This will manifest as losing the data connection when opening an app that uses a data connection, such as the browser. I chalk this up to the phone refreshing the available AP list for which turns on the WiFi, even when it's disabled.
My suggestion is to turn off WiFi when you don't need it and disable anything else that can call it up like the Notify Me setting, Google and Verizon location services, and turn off settings in any apps that might enable it.

Att atrix hd connectivity issues

So i have had the phone for a couple of days and recently i have been having connection problems. My data will stop working even though i have bars and the 4g lte sign is up. I have to restart my phone to get my data back connected. Not even going to settings and turning the data toggle on and off works. Any ideas

Id call att for now and see what they say...

Toggle Airplane Mode. Works for me. I have the same issue.

airplane doesn't works all times.. i prefer suspend the phone for a few seconds..

Are you using any smart actions that affect your data connection? I had the same problem before I realized that the phone automatically turned off data when connected to WiFi. I had set up a smart action to do it as well, which I think confused the device and wouldn't connect to 4G. I had to factory reset to fix it. Left smart actions out of the loop, and haven't had a problem since.
Deep rooted in the mAtrix HD...

Yea i tried the airplane mode and nothing. I had smart actions on but then i turned them off and still have yhe problems. I think im just going to factory reset and see if it fixes the problem. The problem usually happens when im at school where in my classes i get no reception. And after class i get the bars but still wont get data and then i restart my phone and then i get the flood of notifications.

This is exactly what happens to me..

could also be lte problems... as att deploys new towers and works on em sometimes you'll have problems for no reason... which is why i would try to call att or do a factory reset, is all i can think of

I had to factory reset my atrix. I dont use the smart actions anymore and that solved my problem

Yea, I stopped using also the smart actions as they seems more stupid than smart

I will have to disagree with you, once setup properly the smart actions are great. Never had a single issue with connectivity.

[Q] CM10 and no connection to internet

Hello all,
I flashed CM10.0 a few weeks ago and everything was working fine up until 2 days ago, now my I9000 won't connect to the internet at all. I was using Easy Battery Saver which cancels the data signal everytime the phone is idle, but this stopped turning the connection on. I uninstalled it hoping the phone would revert back to normal but can't get connected. I restored the app hoping it would pick up the settings again but still no joy.
I have wiped everything including user data and the caches, done a factory reset and reflashed the rom. The signal did return for about 30 minutes after the flash but the connection has since died again. I've tried switching on the roaming and national roaming, also no luck.
Does anyone have any idea what might be causing this or even how to fix it?
Thanks in advance

I am just guessing, but as from what I understand you uninstalled the application when you were not having the internet connection working. Right? The correct settings have possibly remained overwritten (some applications block the outgoing data traffic by changing the connection settings). Give APNDroid a try and if unsuccessful try going to your phone operator webpages and find the correct connection settings.
I am using CM10 with APNDroid which works fine. However sometimes I cannot connect to 3G as well. Switching the APNDroid on/off couple of times or rebooting solves the issue.

Thanks for the response mate. You guessed right, APNDroid hasn't fixed it and I haven't been able to find APN settings other than the one that is already in my phone. Might reverting to stock solve the issue? My contract is up at the end of the month so I could handle living with GB until then .

Hi again, reverting back will definitely not solve the issue. From what you had said I understand that the internet settings are somewhat messed up.
These settings are bound to your SIM card. By up/downgrading ROM these remain.
Could you check if your APN settings are correct (I assume you need to check with your provider).
Good luck and keep us informed.

Just found the APN settings online. Reset my APN and it looks to be working. I'll keep an eye on it just in case but I think either the ROM or the App messed up the user/password on the APN.
Hopefully it's all fixed. Thanks for all the help.

[SOLVED] Data connection not working properly

Hello, I got an xperia z three weeks ago and it has always worked perfectly until yesterday: I'm experiencing strange mobile data connection issues. I can surf the web but if I disconnect and connect again, the connection may freeze: the H icon (or g or e..) appears and phone seems to transmit data as it shows an up arrow but the down arrow never appears and I can't surf the web. Toggling data and airplane mode may allow me to connect successfully but it's always pretty random..
I started thinking it was a software issue.. So i flashed The phone with the utility twice.. No success. Carrier issue? Nope: it's all ok and apn settings are ok as I can use them. Hardware issue? Perhaps as I found out that removing the SIM card and inserting it back in a certain way could make the difference (higher rate of successful connections).. So what do you think? Could be the SIM card (I got a new one in December though), the phone or something I did not consider? Sadly I can't test a different SIM now but as soon as I can find one, I will try. Thank you!

Does it happen while your using the device or when it's sleeping you turn device back on? I also have sort the same issue but with WiFi..

Suddenly unable to connect to home wifi

So my wife's motox decided to stop connecting to my home wifi/cable modem. My phone (LG G2) as well as all laptops/tablets connect fine. My G2 can see about 8 nearby networks, the MotoX always sees my neighbors network and occasionally a 2nd or 3rd but that's about it. If my home network finally shows up I enter the password and it immediately switches to "Out of range" and shows as a Saved network. I enabled the hotspot on my phone and the MotoX still didn't show the hotspot. Here are the things I've tried so far:
- Forget network and readd it if/when it finally shows up as a visible network.
- Cleared cache from recovery
- Rebooted
- Toggling airplane mode
- Disable just data
- Power cycled cable modem. Also Hard reset it and set the network back up.
- Disable wifi optimization, notify when open network is available, as well as the always allow scanning.
- Switched from auto to 2.4 Ghz only.
- Switched between multiple channels on router.
The MotoX is the Canadian version, 4.4.2 stock, unrooted. Router is an awesome Hitron piece of crap but it's been working perfectly fine for months.
Short of doing a factory reset, does anyone have any ideas?
Thanks

You have already tried everything that I would suggest, short of a factory reset. If you do factory reset, please let us know if it resolves your issue. Since you are not rooted, I'm confused as to how this could happen :/
Good Luck

I am assuming you have already unchecked the "avoid poor connections" option too in the wifi settings.

It was already unchecked so I didn't touch it.

Some routers can't handle certain number of conectinons, try rebooting your router

The router is built in with the cable modem which I've already rebooted as well as reset completely. Also with the phone only able to see a couple of networks at a time when there should be 8 - 10 visible at any time I think the phone is the problem. I just can't figure out what happened.

A few users have randomly had issues with WiFi, and their issues were only resolved by flashing the entire stock SBF as per the "Return to Stock" thread.
If a factory reset does not resolve your issue, you may consider SBFing back to stock. Since you will be flashing the stock rom (with matching CID), this is possible even with a locked bootloader.
Good Luck

I saw some posts about the SBF thing but wasn't sure if that applied to an unrooted / locked device or not. Thanks for the info.

An update for anyone looking for one. Her phone stated working fine yesterday on its own. It picked up and connected to our home network on its own and it can see all of the nearby networks like mine does.
Neither of us have done anything to it yet. Haven't touched the router or her phone since I first posted the problem.
Sorry I don't have an actual solution for you.

Ok so wifi decided to crap out again. This time I did a full wipe (internal storage included) and now wifi doesn't even turn on. It flips to ON for half a second then immediately back to off. Bluetooth does the same thing. I've called my provider (Rogers) and they're sending me another one.
Considering the wifi and bluetooth are on the same chip I guess the whole chip is toast or loose or something. Either way its well beyond a software fix.

You did a full wipe, but did you actually SBF back to stock? As I had commented previously, ONLY a full SBF back to stock can repair a corrupted filesystem. A "Full wipe" just erases cache and userdata.
SBFing actually REPLACES all the partitions. If you haven't tried, you can't say for certain that it is well beyond a software fix. It could have simply been a corrupt file...
Good Luck

If it was my phone I would have tried a SBF but considering it's my wife's she's a big more hesitant to let me and if they're sending us a new one, why bother?
