No Mobile Data - Help please!

Hi All,
I got my Note 2 today, and have run into a problem already
Mobile data (HSPA+) was working when I first got the phone and used it between the shop and the way home.
When I got home, I switched over to wifi to download things.
I then flashed CWM from the cwm-root-note2.tar.md5 file in Dr Ketan's guide using PC Odin.
Then, I flashed Omega v3 via CWM.
All went without a problem.
I was still on wifi and downloading and installing all of my apps.
After a while I turned off wifi and I noticed that I wasn't getting any mobile data connection. I was getting 3 or 4 bars of mobile signal, but no 3G, H or H+ symbol to indicate mobile data.
I messaged a nearby friend on the same carrier and he said his was working fine. So, I figured I must have messed up the mobile network settings,
I checked the APN settings and they were blank, so I put them back in manually.
Still no data connection,
I went into CWM and wiped cache, dalvik and user data.
Still no good.
I downloaded the stock XXALJ1 ROM for Thailand (where I am) and flashed that, did another 3 wipes, but still no luck.
I tried doing a factory reset from the settings menu. But still no joy.
I put the SIM card into my Note 1 and it got a H+ straight away and data was working fine.(when the shop cut it down, they made a nice neat job of it, so the excess makes a decent micro sim holder). So, the network and SIM card are OK.
I noticed that when I first got the phone, the boot screen said "N7100" under "Galaxy Note II".
Now, it doesn't. I'm not sure when it changed.
I also noticed that when I do the under/factory resets, there are still some settings that aren't reset, For example, I set it to WCDMA only to see if that helped and then when I did a factory reset, it was still set like that, rather than the default "auto" that it originally comes with.
Unfortunately I didn't do a nandroid backup, as my phone came with XXALIH (without the multiscreen), so I figured I'd updated to LJ1 first.
Does anyone have any suggestions of what I can do?
Is there a full wipe ROM, or a way to reflash the bootloader and ROM?
It's 3am now, so I need to go to sleep, but this is annoying the hell out of me.
Thanks,
Rich

Carrier please?

True Move H in Thailand.
I don't think it's a carrier issue, as I can put the SIM into my Note 1 and get H or H+ data connection straight away.
Also, I compared the APN settings and I have the exact same settings in the Note 2 and Note 1.
Mobile data was working on the Note 2 when I first got it.
Thanks,
Rich

Turn mobile data on in settings/data usage.

I doubt that his data is turned off in the settings is the problem since he already stated that he tried resetting to factory settings.
I'd suggest simply using odin to reflash J1 onto the phone and start from scratch again. This is why the devs always remind people to do a nandroid backup. In case of situations like this.

Thanks. Yes, Mobile data is ticked. I tried toggling that early on in case it just wasn't connecting properly or something.
I've tried flashing the stock J1 a few ties, but no joy.
It doesn't seem to do a full install, as the circle battery mod I installed previously is still there after flashing stock J1...
I'm downloading a stock XXALIE for Thailand at the moment and will try that.
It's still got 30 mins to go, and I have to leave for work soon! So, I might have to spend the day relying on wifi when I can get it
I'm wondering if the change in boot loader has anything to do with it. (Originally had "N7100" on the boot screen and now I don't, just "Galaxy Note II")

maybe APN settings are wrong? I'm from sri lanka, and I had to add an apn for mobile data to work.

OK, I finally fixed it. Here is what I did (in case anyone else has a similar problem)
Flashed stock LJ1 via odin
Downloaded Galaxy S/S2/S3 CSC
Reset my CSC to THL
Now when it restarted it picked up mobile data signal without me doing anything to the mobile network settings.
I reflashed Omega 3 and lost mobile data again. I tried the Galaxy CSC app, but it says there is only 1 CSC.
So, I went back to stock Thai LJ1.
This time I got an OTA update straight away. After that installed I noticed the boot screen had changed back to showing GT-N7100 again.
ROM is now XXALJ3 and the modem is DXALJ1
Flashed CWM and reinstalled most of my apps from Titanium Backup.
Everything is still OK.
So, it looks like I can't use Omega ROM because it changes the CSC and I can't change it back to THL.
Is there any way to install the CSC separately after flashing Omega?

[Q] Poor mobile data connection after loss and subsequent reinjection of IMEI

Hello everyone, please excuse my noobness. I have spent two days now searching and trying to solve my issue, but no luck. Here are the series of events:
1. rooted i747 and got cwm 5.5
2. flashed liquidsmooth with cwm 5.5 and gapps
3. everything was fine (i think)
4. i tried to flash cm 10.1 with cwm 5.5 not realizing i needed 6.x and the flash failed
5. restored to my liquidsmooth back up
6. realized my imei was 0 at this point and no cell signal
7. used odin 3.07 to flash back to stock 4.1.1 rom from samsung
8. injected my imei using NV items reader writer method
After this sequence of events, regardless of the rom (stock, cm, liquidsmooth), my modem connects to LTE and is fine while i'm using it, but then after idling for 20 mins or more is on GPRS. Sometimes it has no data connection whatsoever. If i go to airplane mode and then come back out of airplane mode it will find the LTE tower and be fine again until I leave it alone or use it for more than 20 minutes.
I am using the correct APN (phone or pta on ATT)
my IMEI is correct under status in the about section in settings.
I have also done this : http://forum.xda-developers.com/showthread.php?t=2036891
i have also flashed my modem with this rom : I747UCDLK3_I747ATTDLK3_ATT (My baseband version is UCDLK3) from this thread: http://forum.xda-developers.com/showthread.php?t=1831898
The issue isn't that I can not connect to HSPA+ or LTE ... the issue is I lose that connectivity after 20-30 minutes and can not gain it back unless I toggle airplane on and off.
Any help or suggestions would be greatly appreciated.

I wanted to update this thread, in case others had the issue.
There was no solution that could be found. I ended up taking the phone in to ATT after resetting to factory defaults and resetting the flash counter. They replaced it and now on CM10.1.2 with normal functioning radio.

[Q] Sprint Note 2 LTE Issue

Hello there, I have been in the search for a perfect 4.4 ROM to work, I seem to be at an impass..
The 2 that I have tried, and Quite enjoyed so far are the Omni ROM and the Cyanogenmod 11
Both roms have the same issue, I cannot connect to a 4g LTE Sprint tower. I know the LTE Towers are working, My mom has the same phone, Sprint Note 2 and I have Mac's Rom on it and is picking up a very strong 4g Signal, yet my phone which sits literly right next to it, Refuses to get any 4g.. I drove around, went to known working areas, Never once did I snatch a 4g signal.
I played with the settings, it is set to LTE mode, I even tried Flashing as a fresh Install..
I tried flashing a Stock rom, but for some reason after it installs, and on boot up the phone does not work. I get a blank screen and literly nothing. I have to pull the battery to get it to turn back on. At that point I have to either Re-flash or restore a backup through CWM.
Any help would be appreciated, I miss my LTE Thanks

Same issue here. Not sprint though...

In cm11 set your mobile network type to cdma+lte/evdo or global. See if that works.
Next you can try to flash a touch wiz rom and do a hands free activation, verify lte works on the touch wiz rom, then flash to CM11 and see if you can connect to lte.

I have tried setting it to both. Global shows no signel what so ever on anything, I currently have it on cdma=lte/evdo and I just get a good 3g signal..
I might try that one out, Which is a good touch wiz rom to try and do that with ? I dont think I even tried a touch wiz rom yet

Personally I would recommend doing this:
Backup everything to your PC (both internal and external)
Delete the contents of the "0" folder on your internal card. If you use ES File Explorer, you'll need to enable root access, and then while in the app hit the menu button. The left menu will slide open and you'll see "Local".... underneath that you'll find the "0" folder. The problem is the way CM and Touchwiz mount the file system - they don't do it the same way. So when you do a factory reset in CWM, it doesn't clear out one of those folders. (I found this thread helpful - especially posts 2 & 4) I had major data problems on CM10 for 2-3 months, then I found this out.
After you do that go back to stock. Make sure you download the keep root file as well.
To play it safe, once stock, I highly recommend entering ##72786# in your dialer. The phone will grab the latest prl and update your profile. Whether or not you want to update the software (incl modem) is up to you, but I'd rather not get into the knox world.
Verify working gps. (I prefer "GPS Status")
Then go back to CM11.

I will try that out thanks

Update us on your progress.
If it works, consider hitting the thanks button - at the very least the guy in that other thread - I know I thanked him - his info saved me from going crazy!!!
I had working data (3g/LTE) on any touchwiz, but not on CM. It turned out that I had some corrupted data that wasn't getting deleted upon a factory reset. After I cleared out that data, everything was fine.
Hope your phone is back to normal!

Finally was able to download everything and run the tip, Thanks a lot dude! That helped and that did it ! I got 4g Back and everything is all peachy!!! Thanks again!

[Q] Rooted, Carbon ROM, Mobile data and Wifi problems

So I have rooted my S4 Mini, as described here and installed JellyBean version of Carbon rom for S4 Mini LTE (i9195, my model).
I used this guide when rooting and I used this rom version.
Everything works as should, but my data network is behaveing strangely. It's not that it's not working, it does connect to via H+, 3G (which imediatley turns into DC which is something I haven't seen on stock rom). But it connects only sometimes and doesn't work at other times in places where it definitly should. And 4G never works (in places it worked on stock).
Disregard Wi-fi part, I had some issues with my router, there was never a problem with my phone (at least regarding the Wi-Fi)
My APN is fine, it wouldn't be able to connect otherwise (and I checked the settings).
Any ideas?
Ask for any additional information. =)

I hope somebody else knows, but if you don't find any solution just change the rom

FOUND FIX!!!
I too had this problem on 4.3.1 carbon rom. I wiped data using recovery boot and at first it didn't help. But it started working again in a few seconds. Magical fix. Let me know if this works for you too.

same problem. Do you use a 3G or 4G signal from your network provider ?

Possible fix for you

Hi again, i spent hours trying to fix this and came up with a solution:
Make a back up of your current rom
Use Odin to flash the I9195XXUBMJ7_I9195OXABMJ7_DBT file ( can provide if needed ) to go back to stock firmware
Make note of the APN settings of the stock firmware, then restore the back up and change the apn settings to the same as the stock and it should work.
This worked for me.

Went back to stock and it worked well enough (as intended). However I just installed the official Cyanogen ROM and it works like a charm. Latest nightly build (01.02.2014.)

Cannot SEND SMS Tried Everything Please HELP :(

All of a sudden today I cannot send SMS.
I was on a really old build of Cyanogenmod12 (April 22nd I believe) as any time I tried to update to newer Nightly builds I lost all Sprint service could not make/receive calls or texts, etc.
I decided I was pretty fed up with CM12 so I decided to go ahead and migrate to AICP. I wiped everything TWICE in recovery, loaded up AICP and it works fine, I get LTE signal, etc. However I cannot SEND SMS, I can RECEIVE SMS I just cannot SEND. I had done some data restores with Titanium and I figured that somehow some way that might be messing with things. So I did another 100% fresh install after wiping everything.... I can send/receive calls, receive SMS but I cannot SEND SMS
I am really at a loss here guys, ANY help would be greatly appreciated

*#*#4636*#*# change it to CDMA wait 30 seconds send an SMS and do *#*#4636*#*# again change it back to late/CDMA n should be ok

I stayed up all night last night working on this, let me update the thread with what I have done so far.
I was looking at some stockish ROMs and I noticed that there were warnings on some of them stating that you needed to have the Sprint OTA 5.0 update installed prior to flashing, which I actually never got. My phone came out of the box with Kit Kat and I never installed the 5.0 update, I went straight to CM12 5.0 instead. So I had a theory that there might possibly have been some sort of network data profile, etc or something out of that official 5.0 OTA that I never got that was somehow causing me problems. I decided to revert back to complete bone stock.
I wiped everything and flashed the N910PVPU1BOB7 file (MD5 = 7304e42cf0e241553d8db9e3c3eeed81) which was the official Sprint 5.0 OTA. Loaded it up, updated the PRL, Network Data Profile, etc, etc, etc.... everything works (relatively speaking...... TouchWiz sux balls of course). I have LTE signal, I can send/receive calls, I can send/receive SMS... all good.
So at this point I decided to re-wipe and flash AICP, with the emotion Kernel (latest builds on all). Load it up.... same problem as before. I have LTE signal (stronger than on the stock Sprint ROM), I can send/receive calls, I can receive SMS but I still CANNOT SEND SMS
I tried a few things at this point. I tried to manually reset the Sprint network connection on the phone by dialing ##72786#, this did not work, it returned an error "incorrect MIM code". I tried the *#*#4636*#*# that I have seen suggested in multiple places, this also did nothing, it returned an error "incorrect MIM code". I also noticed on the "mobile networks" tab, and this is true for BOTH CM12 and AICP, that it has the setting at "Global" by default and everything works with exception of sending SMS. Now when I click that tab it only has 3 options LTE, 3g, 2g.... for some reason "global" is not an option, neither is CDMA. Whenever I select LTE it automatically drops me from the Sprint network PERMANENTLY until the ROM is re-flashed there is no way to reverse this. I cannot even dial the manual programming codes "*#* etc" as it just simply says "no network service". If I try to automatically connect to the sprint network through the network operators tab it does in fact find Sprint as my provider, however if I click on Sprint to connect it processes for about 2-3 minutes and then simply returns an error of "cannot connect to the network at this time, please try again later". Again the only way to reverse this is to re-wipe and re-flash again which puts it into the unselectable "global" network setting by default where then I will have LTE signal, I can send/receive calls, and can receive SMS but not send SMS.
So that is where I am at, I stayed up all night last night wiping, flashing, and testing different things over and over. Nothing seems to work 100%, except the stock 5.0.1 OTA which is what I am on now. I really hate TouchWiz and for some reason I get a much weaker LTE signal on stock compared to either CM12 or AICP (I have no clue why this is). I am really at a loss here why everything works on the custom ROMs except for sending SMS..... willing to try almost anything to go back to a custom ROM.
Let me know if you guys have any other ideas.

Well great news I have finally resolved the SMS send issue

pbedard had tried to help me with the above post (which I appreciate, thank you), and I have seen the same advice in other threads. One slight problem though, he slightly mistyped the manual programming code it is actually *#*#4636#*#* not *#*#4636*#*# which I had tried entering ohhhhh I dont know 30 times? :silly: And it always returned an "invalid MMI code".
I had tried everything and after spending a full day on TouchWiz I was determined to fix the issue so I could go back to a custom ROM. I was even manually creating and deleting APNs, etc. Nothing would work. Right as I was about to finally give up (after literally 12hrs of researching the issue and testing fixes) I was reading the official CM 12 thread and came across the "fixes" post:
http://forum.xda-developers.com/showpost.php?p=57613217&postcount=3
Because I had tried entering the manual programming code so many times I happened to notice that the last 4 key strokes were not what I had been entering. I entered the correct programming code, boom the Phone Info menu pops right up I follow the directions and what do you know send SMS finally works .... wow what a relief, I am on the latest AICP release on the emotion Kernel and everything works like a charm.
Also by setting the phone to LTE/CDMA through the manual programming menu I have the strongest LTE signal by far, full 100% bars at all times (I live right next to a Sprint tower). I have never understood why I only got 1-2 bars on the stock ROM and 3-4bars on CM12/AICP through the default settings. Anyway thanks for help and I will list out exactly what I did to get it working.
- 100% Stock ROM
- CF Auto Root and TWRP install through Odin
- Reboot to recovery
- Wipe Dalvik cache, system , data, and cache
- Reboot to recovery
- Flash emotion kernel (optional)
- Flash latest AICP build (or custom ROM of your choice)
- Flash latest stock Gapps
- Reboot system
- Confirm Google Messenger is the default SMS app (it will already be if you flashed 5.1 stock Gapps)
- Dial *#*#4636#*#* ("Testing" menu screen will pop up, select "Phone Information")
- Scroll down to "Set preferred network type" click it and scroll up and set it to "CDMA auto (PRL)"
- Wait until 3G signal comes online (takes about 10 seconds)
- Change "preferred network type" to " LTE/CDMA auto (PRL)"
- It should take another 10 seconds for LTE signal to come online and you should be good to go to send and receive SMS ! :good:
