I have AT&T Note, stock ICS, rooted. I have been having problem with inconsistent data connection, even though I have good AT&T signal. For example:
1). Signal is 4-5 bars
2). I CAN make phone call
3). Open browser, Gmail, etc - the "4G" icon shows it's trying to connect, but nothing happened. All the application will timed out.
I tried this in different locations (home, work, airport, etc.) and same problem.
I didn't change the APN or install custom ROM. I am trying to figure out if this is just my phone (bad radio, etc.) or a widespread, known problem for AT&T stock ICS.
Please chime in if you have the same problem.
Did you try powering down.... Then a battery pull..... Battery back in.... Reboot..... Turn off wifi... Make sure data is turned on..
Write back.... Good luck

I did try those, specifically:
1). Power down and battery pull out
2). Airplane Mode
3). Disable WiFi and BT - leave only cellular signal
The only thing I have not done is hard reset.. But before doing that (it'll take me a long time to re-configure everything), I want to get feedbacks from other first..
BTW, the ONLY thing I can think off that MAY mess up with the connection is Avast! Anti-Virus. It has a built-in firewall (root required) to prevent select apps from accessing the Internet. However, with WiFi, I have no data connection issue even with Avast! firewall running.
Un install avast and see if that helps.

I did, same thing... Can make voice call but no data. Even when I rebooted and pulled the battery. About 10 minutes later.. data magically comes back!
Does anyone else have this problem? If yes, please chime in..
I am thinking of doing hard reset. Will this make my Note lose root?

I can't reset the default APN...check I can't even edit it. I think AT&T blocked it.
Did you just get the note or did this just start happening? If you just got the phone did you buy it new or used?

you are right.. you cannot edit and change the default ATT APN....
BUT!!!
You can create a new one.... and choose the new one over the default...
you are allowed more than one APN...
Modem .....and APN settings are the most likely causes.
APN settings first of course.....g
Thanks for the suggestions.
The original APN cannot be edited, so I created a new APN and select that. When I press the "back" button and go back to the list of APN, the phone AUTOMATICALLY selected the original APN, not mine.
I selected that again, press back button and waited for 5 minutes (in case the phone trying to update whatever it needs with the new APN). Went back to the list of APN and the original APN was selected again! (???).
So I think something went awry with my phone (I already uninstalled pretty much everything), and just for a test, installed a new ROM (Padawan v7). So far so good, but I haven't done extensive testing (at home, not traveling) yet.
Of You Are on a stock room when you are in the apn's try taping menu and see if you get a reset defaults option

I was playing with the *#*#4636#*#* menu in CMX and changed my band to Australia. I then lost all connectivity but wifi. I figured I'd just nandroid back to my fully functioning CMX - I was wrong. After restoring the nandroid, the phone still won't connect to anything but wifi.
I then saw this post and flashed meanbean to use the Sense dialer.
None of the instructions worked! When I try to ##786# reset all my data, the phone will do its thing and then boot back up into meanbean and ask me sign in to my accounts.
The DEVICE_PROVISIONED=1 doesn't exist in my build.prop as seen in this post so I can't use the simple method. :crying:
Any help is greatly appreciated. I only have wifi while I'm at work, so in 5 hours I'll be screwed.
EDIT: Almost fixed it! I nandroided back to CMX and tinkered with some more advanced settings. I figured I can't hurt anything more than I have. It's now connecting to the network and 3G, but says it needs activated. Finally, progress!

Thanks guys, I did get it fixed. Once I got some sort of connection reestablished I needed to activate the phone. I called Sprint customer service from my work phone and they refreshed all my data/connections. That allowed me to connect to the network, but not use it (if that makes any sense). I then downloaded the deodexed stock rooted JB ROM from here. After flashing that and booting into it, it said "hands free activation" and then starting updating the PRL before asking me to set up my accounts.
Hopefully my story helps anyone who gets caught up in this issue.
One more thing, upon reinstalling my cmx nandroid, I checked the build.prop file and it had the DEVICE_PROVISIONED=1
I changed it and that's how I got the phone to reconnect to the network (still no use of the signal though at that moment). That's when I flashed to the stock rooted ROM and everything was fine from there.

Occasionally I have a random reboot. It happens when you flash with any regularity and I hop ROMs fairly often. Regardless of which ROM I'm on, sometimes after one of these reboots, my APNs will be gone and my phone has no network connection. I've tried re-entering my LTE configuration manually and it just disappears. I always have to reinstall the ROM in order to get them back. It's quite a nuisance.
If anybody could enlighten me as to just what the hell is going on here, I'd appreciate it.
Cheers!

I've had this issue on CM10 reboots. Nothing will get the APNs back or get them to stick without rebooting. Typically, if I don't see that I have a signal then another reboot will bring the APN settngs back. Scary, given past issues that I have seen with APNs fully disappearing (in Captivate) but, again, subsequent reboots bring them back, Have not been able to figure out any pattern or reason for it hapenning. The good news is that I have not exprienced in th day since I hve had CM10.1 On the ther hand, I have not had any random reboots either....:good:
I had that happen in a rom a few weeks ago ,all apn,s disappeared ,however after fixing permissions and then resetting the apn I was ok

I am new to root and ROMs so perhaps I overlooked a setting.
I just rooted my phone and flashed CM 10.2 a few days ago and I cannot get 4G anymore. I can only get 3G. I have tried a few fixes like dialing *#*#4636#*#* and adjusting the APN settings but nothing worked. I have the LTE button ON and I am wondering if I am still getting 4G because I have LTE on and it's just showing 3G. But I don't think that's the case.
Any help or tips would be greatly appreciated!

reflash stock rom. make sure you have 4g. flash the vram3c radio then flash cm10.2 rom. you should have no problems with 4g after that.
I will try that. Thanks!

I tried flashing the radio and CM again and sometimes 4G comes up for a few minutes and goes back to 1X. This happens where I have gotten 4G before. Maybe the radio isn't as strong?

My personal experience, living in a fringe signal area, is that AOSP roms just don't have as strong a signal as TW roms (it presumably has to do with how the RIL had to be hacked/reverse-engineered to work for AOSP). I would prefer running AOSP, but unfortunately in my experience on my S3 and Note2, where I am located on the fringe of full 4G coverage areas, I have the same issues as you: on TW, full, fast, 4G; on AOSP, very obviously slow 3G or 1X.
Edit to say I've only tried 4.2.2 ROMs, haven't tried the 4.3 ones yet, so if I'm handing out wrong/outdated info, I'd love to be corrected.
I am now running a stock 4.1.2 ROM and still cannot get 4G. I now for some reason can't even dial *#*#4636#*#*. When I try it just says "Welcome to Verizon Wireless, this call cannot be completed as dialed." Anyway to get that number to work so I can check my networks again?

Try going into settings and factory reset phone now. If that doesnt work, reboot into stock recovery and factory reset from there and reboot. That seems to restore signal for those of us that got stuck in roaming mode from the Carbon thread. Might help your problem too
So I decided to re-flash CyanogenMod 10.1, adjusted the APN settings again, and I have 2 bars of 4G right now. Usually 4G will flash a couple times and change to 3G, but it is staying 4G, so hopefully it stays that way!
Well it stayed 4G for a bit until I turned WiFi on. The moment I turned it on, my 4G went to 3G. I turned WiFi off and I still have 3G. Anyone know what would cause this?
EDIT: My network type shows eHRPD with 3G, where as when I had 4G (before I turned my WiFi on) it showed LTE. If this helps any.

Where do you live, i know the mid Circle drive all the way over across platted to the airport are just dead zones. I lived on Verde drive and rarely had good signal, then when i moved up circle behind the bowling alley i never had a good signal. Just something about the antennae in that area. T-mo is a complete bust in that area. But i'm sure you probably all the way over on the Nevada side completely making what i said irrelevant.

Do a search on towers in your areas. If I remember correctly the closest tower to you in right by the interstate by the new (now not so new) MCD's in Security. That tower had alot of problems in the area past the Olympics complex all the way back to Peterson because of the radio towers for the Jets. I have been gone for almost 3 yrs so don't take what i say as truth tho. Just how it was when i was there.

I've had that problem before. .I used a mod like this.
This mod is from DroidXcon, Try this and hopefully it will work. (make a backup of your buld.prop first)
Instructions:
1)Go to market install BuildProp Editor
2)Once installed find and open Build Prop Editor
3)Hit the menu button and select Edit
4)Scroll to the bottom of screen and add the following lines
Code:
ril.sales_code=LOL
ro.csc.sales_code=LOL
5)Hit the save button at the top right hand corner of the screen(looks like a disk)
6)Once this is done saving restart the phone
7)After restarting go to Settings>More Settings>Mobile Networks>Access Point Names>Menu Button>+ New APN
8)Add desired carriers APN info, when finished hit menu button and save
9)Power down and change to your desired SIM card if you hadn't already done so
10)Power back on and go to Settings>More Settings>Mobile Networks> Access Point Names (if done properly you should see the APN data you entered for your respective carrier).
11)Select the respective APN listing and then you should have working data

I tried this but having the same problem, so I decided to save the APN each time I edited an item, and every time I would change the MNC and save, it would not be on my APN list, and it would be blank again.
Bump... also having this issue. Trying CM 10.2 for the first time since August. It had Bluetooth issues back then, so I've been running Bean's ROM until yesterday. Can't get 4G serivce in what is absolutely a saturated 4G area...
Was able to fix the issue by wiping the phone completely (including internal storage!), installing Bean's ROM, doing a factory reset, then coming back.
FWIW I always wipe internal storage when going back and forth between 4.1 and 4.2+ roms, seems to alleviate any SD card issues that can arise from the changes to filesystem in 4.2.
Sorry guys, thought we had one of these already.
Just curious about the V_2.3.1? Mostly the reception, but....
Is the Reception any better - mainly for those that have lousy reception to start with.
Are you having any issues?
I haven't heard anything yet so let me know :good:
I have decent reception at my house but I think the beta added a bar to it (from 3 to 4). Definitely better at my son's school. I was only getting 3g there but now get LTE. The big test will be at work but I'm on vacation and don't go back until next week.
I was so amazed that I actually noticed a better internet connection I never looked at my signal bars there is an extra bar or two in my house, which I swear I only had one if that all the time one thing is that I'm not sure if it is the ROM or me but shutdownani is really choppy, every since 2.2 but I try modules sometimes that make my phone unstable like xprivacy& cool tool which I immediately remove but deff noticed improved signals, like I actually see the difference
Updated to 2.3.1 to check apn, I checked apn setting. They didn't change, so I selected reset to default. Then I lost internet and apn kept selecting VM. On reboot phone app fc. Had to revert apn.config and do ##scrtn

Yes, I already did that edit. 4 me in a specific area the 4G is slower than the 3G. I wanted to try different apns. But those APN would not connect for Sprint at all
What is the intended effect of that file? Sprint has its own APN on a profile update
Works Well for me, definitely see improvement with Switching from 3g to LTE. I also find an LTE signal much quicker. I work in NYC, before the 2.3.1 update I would struggle to get an LTE signal once I left Penn station, now As soon as I walk out it grabs a signal. engine95 you are the Man Bro.
@engine95
I think the apn.config has bad settings for Sprint OTA, I've edited going to test, should be able to activate phone with the edits.

I'm not sure what you were trying to do prior to the above.
If you're talking the apn in the beta, It seems to work better for all of us.
If you're talking about modifying that apn for hotspot, it works also.

The original, and the beta do the update profile/prl as they should. And "Activate device" is the telltale.
But, you can't use the beta on a fresh install. Meaning on a full ROM. It'll only work as an update.
Remind me again what issue you're trying to fix and I'll see if I can help.
Edit: In V3, it has a new zipalign binary that does what you want.
Did some testing, updating profile/prl works because it uses apn settings from activation, but if you do ##72786# which erases everything then reboots and does an activation using apn.conf.xml to connect to ota. But the setting don't work for ota. Crashes phone app and then only way to fix by wiping and doing clean install.

That would be right because it has to go through the setup all over again. Just like a clean, full rom install. And it can't find the apn it needs.
Yes, all that file is, is a hack. Not a fix.
Well I'm going to keep working on trying to make the hack safe,
The new native hosts file appears to be blocking random pictures in the play store. Not sure which URL is the culprit but I disabled the file temporarily and the pictures come back. Other than that v3 is running great. Thank you.

That can happen. If they are too restrictive, then you might have to use the stock Sprint one.

Mine are but the timing is about 10 sec between blinks.
I guess check your settings, and maybe wipe cache and dalvic?
I just realized I don't have the native Wi-Fi calling app. Can I ##72786# from v 3.01 and get it to download or is that only on factory ROM?
