Did my APN get screwed up? Getting 2g only

So long story short I flashed a theme that wasn't compatiable with Wicked V5 rom so I dirty flashed wicked back and noticed I wasn't getting 4G signal anymore. So I thought it was a dirty flash issue so I clean flashed to another rom & now I'm still getting only Edge signal. My data plan is 2GB before I get booted to EDGE & im currently at 1.7gb so Tmobile hasn't shut off my cap. I even called T-mobile tech support which was useless cuz they made me do a bunch of stupid stuff like restart phone, check my mobile network etc & they refreshed my line but that hasn't done squat. So currently they said my area is fine signal wise but I'm thinking maybe my APN is screwed up? idk

Check ur imei number I had the same problem after a bad flash..if its on 0 or a generic imei let me know and I'll walk you though getting it back. Imei is in settings-aboit phone - phone status.

I did exactly what http://www.youtube.com/watch?v=_AlQmfMJBK0&list=FLtKzl9OBgslau4mpj3kYj9Q&feature=mh_lolz this video said . Working on restoring the 4g now

I did everything the thread said about backing up / restoring but I'm still on Edge in the end -____-

ok i lied it somewhat works but. I have set network mode to WCDMA only to even see the 4g logo but once I do that my cell signal becomes very unstable & dips back to 0-1 bars. But if I go to LTE/GSM/WCDMA aka auto i go back to edge -____- so overall I'm still on edge. I've tried it 3 times, triple checked to make sure I did nothing wrong & same result still
From the 2nd link you said me the only thing I didn't do was "Inject your IMEI back into your phone" because there was no need to since the 1st link u sent me told me how to get IMEI back & I didn't "If you still have slow connections after that consider flashing stock again through Odin and then pushing the generated file onto the phone."

Did you use peoplesarmy data restore app?

I'm not an expert but I can tell you exactly how u did it... Evil1art said that his ROM backs up bur efs folder. You might just be able to restore it from there assuming that you had flashed wicked rom before .ohh and did you is the no trip triangle away and reverted back to stock ROM.

Can you give us some info? Is your device stock? Is it rooted? What Android version are you running and are you on a custom rom? If you can, post a picture of your About Phone page so we can see versions and firmwares please
With those questions answered we can take a look and see why you're not receiving your calls. There are a few reasons this could be happening, ranging from data toggles to APN settings. Without knowing what I'm working with, I can only speculate. When noticing these missed calls are you on a particular data network? 4G LTE through AT&T will momentarily disconnect and run on 3g while a call is implemented, then return to LTE 2-3 seconds after the call has ended. Maybe you have an option to prefer LTE and it's not disconnecting the data to allow the call? This may only occur on a custom rom though. Check your APN settings under APN type and make sure things like default,supl,mms are there.
If you're on a stock rom with stock recovery, you may want to consider backing up your data and performing a factory reset. This may not help at all though.
If you know what you're doing, and have root on a custom rom, then chances are you know how to flash a new radio (modem) and may want to research ones available to you and try flashing one of those. (NOTE: Be sure you know what you're doing before flashing anything, and remember to flash a radio (modem) twice for good measure. - MAKE SURE the modem is compatible with your phone model and your rom.

Mine does this every now and then. I assumed it is a network thing, but it may not be.

That is when it happened the first time for me also...and for a few days got 2 different stories. It started up again yesterday, I thought that I would post on here about it. I have come to a pretty safe conclusion that people on here know more about these phones than the people at Sprint. And I am thinking it is a network issue again...it has been ringing like it should this afternoon.

Area code 336? That's in NC, and where I live. Seven of my coworkers have switched from Sprint due to issues with the network. It is a local issue here though, and in Sprint's defense, they are trying hard to fix the issues. (I'm not knocking anyone or any carrier
If we are sure this is a network issue, it may be best to contact Sprint and ask if they have had others complaining about the same problem.

Help with data connection on custom roms

Hey guys this is actually my first post and I am still somewhat of a noob when it comes to rooting the android system. I recently rooted my GS3 on AT&t and I'm sorry if this has already been posted about, but I need some help. Every ROM I have tried which includes paranoid android, CM, and a handful of others I can't remember the names of off hand all have the same issue. Whenever I go from basic 4G to 4G LTE I loose my data connection. When I go back to basic 4G I have to restart my data connection to reconnect. The ONLY ROM I have found that doesn't have this issue is the Synergy Touchwiz.
Am I doing something wrong?
Thanks again for any help and again I'm sorry if this has already been posted about.

OK so I just checked my APNs and just ATT was checked. I switched it to ATT LTE. We'll see if that works and if not I will check again.

[Q] d2usc - 4G issues

Hey all, I'm at my wits end trying to figure out what's going on with my phone/service. First off I hope this is the correct forum since none of them officially address the US Cellular version of the S3.
So what is happening is that my device seems to only want to connect to 3G. I am running the latest nightly for CM 10.1. It all started last week while I was in the twin cities on data roaming for a few days. On my drive back to Wisconsin I notice I would go in and out of 4G service.. by the time I hit home I was on solid 3G service. This was last Friday. I knew there was some work going on the towers in the area as my brothers 4G service started working on Sprint. I just assumed it was something to do with that.
By Sunday and still on 3G, I called tech and they did everything under the sun to try to get me back on 4G to no avail. They ended up sending me a new phone. When the new phone arrived on Tuesday I did a factory reset on the old phone just to clear everything before sending it to them and I noticed it went back on to 4G. This was on the stock ROM, rooted still.
So I switched the phone over to the new one and sure as hell, comes up in 4G. I replaced the recovery and restored a backup I had.. phone pops up.. 3G. :crying:
I did a factory reset a few times and nothing.. still would only come up in 3G mode. I then restored a backup I had for the stock ROM and what do you know.. 4G. Flashed a fresh download of the stable 4 snapshot.. 3G.. then I did a factory reset and what do you know .. 4G.. reboot the phone.. back on 3G.. Tried AOKP.. 3G..factory reset.. 3G.. Back to CM 10.1 nightly.. 3G.. factory reset.. 4G.. reboot.. 3G.
I cannot figure out what the hell is going on.. it clearly isn't hardware as it's now happened on two phones. I thought it might have had to do with being on data roaming for a few days so I waited until the data billing cycle finished (the 6th) but no luck.
I'm at wits end.. I will try anything at this point to get it working again with CM/AOKP.. doesn't matter.. just want my 4G back!

Your phone does not have 4G, It has HPSA.
On AOSP/AOKP, your connection will show up as 3G until it's being used. Let's see some speedtests.

Don't go by what it says in the ststus bar. What does it say inder Settings > About Device > Mobile Network type?
Now go start a large download, like a rom or something. While its downloading check again and post what you see.

Speeds
Thanks for the quick responses guys..
First thing was my status bar was showing 4G for about a year.. it was just recently I started having the issue. I used to get about 20Mb/sec down and now I'm getting about 800Kb-1.5Mb. It's clearly much slower than it was.
And the network type is CDMA - EvDo rev A:6

Try going under Settings, More Settings, Mobile Networks, and try a different network mode.
Sent from my SGH-T999L using xda premium

Its selected as LTE/CDMA/EvDo. The only other option is CDMA/EvDO. I think it's set correctly.

What about Network Operators? Have you tried checking or trying a different one?
Sorry, I just don't know much about the usc model.
What is the model# btw.

Not sure what you mean by network operators but the CDMA subscription is set to RUIM/SIM (which it should be) and the System Select is on Automatic and not Home Only.
Model is SCH-R530U

Under mobile networks you can manually search for and then select an operator.
Judging by your model number, you will likely find more and better help and probably others with your phone in the Verizon forum. (Possibly Sprints, but most likely Verizon)

Thanks. I think I found the answer.. some code in CM 10.1 was causing the NV to lose it's information. A code change was put in to prevent that from happening.. I just need to go back to stock and flash back to CM.
Thanks for the help guys!

Everything I've read involves going back to stock, factory reset, and reflashing. Is there any way to resolve this without reverting to stock? Or is that the only way? - Does it need to be unrooted? And also, one thing I was curious about, I have a stock backup, would flashing that, and then reflashing to a current CM backup do anything, or does it need to be a clean flash?

I would go totally back to stock and start over. It wouldn't even take more than an hour to do everything.

Yup, if you're having problems, taking shortcuts often result in more problems and more time involved than just starting over clean.

I was having the same exact issue on CM10.1 RC5 -- called US Cellular and eliminated everything but CM causing the issue. Flashing back to an earlier version of CM, trying RC2 first.

Do you have the SCH-R530U? If so, see my quoted post below.

Went the revert to stock and reflash route. Issue is resolved. I did have to do it twice, as after the first reboot with RC5, I lost 4G again, skipped it and am running the 6-19 Nightly and have had no further issues! Thanks for your help. You guys are awesome!

So since the sense 5 roms is compatiable with us s3s i thought i could flash a att galaxy s3 rom and it booted and i had signal bars but no 3g i restarted and no siganl at all searching for signal. Does anybody know how to fix this? It doesnt show my phone number just imei.
EDIT: Fixed my problem. Had to reset my network settings by dialing ##72786# on a stock sprint rom. The phone restarted and everything came back.

Ok so just because the sense5 rom with no radios is flashable across different platforms you ASSUMED that you could just flash any ATT rom on your Sprint phone?

Ha ha ASSUME very funny. You acting like you never made a mistake before. Yes my sprint phone on Verizon prepaid really not the pages plus one but it's the closest thing to it. But I fixed my problem and learn from you mistake. I just had to reset my network settings. The only reason I posted in flashing the phone to Page plus thread is because maybe he have had the searching for service problem before and could give me some information about what I could try. Like try to reset my phone networking but I found out how to do that.

Your signature says your provider is Pageplus that's where I got it, not from what thread you posted. Glad you got it fixed.
