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?

Cannot Connect to Mobile Data

Good day Gentlemen and Ladies,
So, as you the title states I cannot connect to mobile data (3g). (Before posting this I had done my research trying to find a solution and I cannot find any solutions) Let me tell you a little bit about my Galaxy Nexus SO originally when it was purchased it was a yakjuxw and I flashed to stock yakju-4.0.4 by this methodI can not link the video atm as I am a noob here) (I am sure that I did not skip any steps). I updated to android 4.2.1 all OTA updates and since that day I cannot connect to mobile data. I am pretty sure this is a software issue unless its a coincidence that my device fails on me at this point in time. Everything worked fine before i flashed it. I have tried going into *#*#4636#*#* and making sure my network type is correct as well as the radio band as automatic. I tried rebooting the device, I turned on mobile data and waited for +2hours for it to connect and nothing. I am sure I did not reach my mobile data limit as it is the beginning of my billing cycle. So, if anyone has any solutions would you be kind enough to give me a link or instructions on how to fix this problem. I recently also got double my data free of charge (from my provider) and I can't even use it Lol... Thanks!

1. Settings -> About Phone -> See your baseband? Does it exist or does it say Unknown?
2. Attempted to reset APN?
3. Tried your SIM card in another phone? Does data work on that phone?

Man you are a genius thank you. It was an APN problem. I think when I flashed it the server # and port # went missing or something so I added those and 30 seconds later it is all working! Thanks again my friend. And for anyone who has this in the future you can access you APN settings->more...->mobile networks->Access Point Names (and APN vary on provider)

I recently had CyanogenMod 11 installed on my phone and I noticed phone calls, messages, and WiFi worked but when I turned my Mobile Data on, It did not work even though it showed it was on. If your issue has not been resolved, I suggest you check this out - http://forum.xda-developers.com/showthread.php?t=2540998.

who is the wireless provider?

It's PlatinumTel (PTEL), which is a t-mobile mvno. I should note that i have the bootloader and the modem matched, have tried factory resets, and even downgraded to previous version (before updating bootloader to latest so i don't brick). Ptel tells me i need to update my APN, which basically was their standard msg... no help there. Thanks.

Hi, so... there are bunch of links and downloads on that page... i do have the latest bootloader and modem... can you tell me what you think i should [try to] update to make the mobile data work? BTW, at least on my phone, the mobile data icon doesn't even show. Not even 3G or whatever... thanks for your help.

RESOLVED!
Ugh. So after countless flashes, resets and wipes, turns out that PTEL needed to do a Data RESET on their end. So much misery for such a simple solution that they could have given me. If you're a PlatinumTel user, and this may apply to many other providers, please try telling them to reset their data service for you before trying anything else. Hopefully you won't go through the misery and time wasted that i have gone through.:cyclops:

All of them are stock but I personally chose upndwn4par - Full - Features : Odexed, Rooted, Knox Removed because I really didn't know what the other ones did. (PLEASE NOTE : Neither the developer or I are responsible if you brick, or mess up your phone! This also deletes everything on your phone so do backup if you want to save your important files.) When it finished downloading, I put the file on my phone's internal storage (SD card works too) then went into recovery mode using TWRP and installed the rom onto my phone, then while I was still on TWRP, I deleted the cache and data, it then reboot and then I had to set up my phone as if I had just bought it.

THIS NEEDS TO BE PROCLAIMED!
PTEL locked us out of voice once before, which also required a reset. That was also with a phone change so maybe a security measure? Never thought about it happening with data.
So many hours wasted.
On calling, the PTEL CSR first reset the data, then helped with a new APN. Note that even with the correct settings in an existing APN and the data connection freshly reset, the phone (SGN3) refused to connect, even after a reset. Added APNs had to be deleted, then a new one created, which then connected immediately. (Pissed and happy at once.)
Thanks, @geesedude, for this info; wished I'd found it sooner. (Have to stop assuming that if it doesn't work, must be something I'VE done.)

Glad that the information helped you. Yeah, i mean... since we mess around with our phones, we always first assume it's something we did, which really can't be blamed for thinking that way. Like you, i searched the web for a solution and it was out of desperation that i called ptel, and the CSR happened to suggest it (they were out of ideas, too), and it happened to be the solution. Not sure why they have to do this in the first place, but i am guessing that there are stricter guidelines from TMobile for the MVNOs, and they have to do some things manually. At least now i know to contact them first before spending hours searching for something that may not exist!

Flash latest factory images

Hey, did that, flashed all the factory images.

I just bought a used phone on eBay for a friend of mine, and he's having the same issues. Every time he tries to connect, the phone detects WiFi but doesn't connect. I had him reset his modem and router, and still nothing. He did factory settings on his phone as well, and still nothing. I had him find free WiFi at a restaurant and try that route, and he's still having issues. Will flashing new updates fix this issue, or is there something else needed in order to fix this solution?
I guess I can always have him send me his phone since he's not tech savvy! Any help would be appreciated.
Thanks

Have you tried the N Beta? https://www.google.com/android/beta
Shouldn't make a difference, but nothing really to lose by trying it. Other than there's a data wipe if you go back to stock. When I turned it off because some apps didn't work, it installed an OTA version in one shot with the latest version up to that point. With the data wipe. No security updates needed on top. That shouldn't make a difference either, but maybe it will.

Cellular data stopped working, help

Zenfone 2 ZE551ML on straight talk,
stock ROM 5.0.1 latest release(not beta tester).
have tried resetting APN settings
Have set APN settings to straight talk directed settings.
have multiple disabled and enabled data and disabled data caps from phone.
multiple restarts, multiple attempts to manually choose network with error messages saying cant connect at this time try again later.
AT&T should work just fine even t-mobile LTE service. they both worked a couple days ago.
ive contacted straight talk and they've had me reset and update the APN settings. had me restart the phone a few times, no luck
still receive texts and calls just fine.
any advice would be great. (if i can avoid resetting the phone to factory defaults or installing a custom ROM that would be ideal)
thanks,

I have straight talk and while I never had a problem with data I have had some other problems. Any problems I ever had was solved by dirty flashing the same rom I was running. Since you are on stock you should have no issues downloading .184 LP from ASUS and using stock recovery to update with ADB. On a side note I have been running the MM beta since it first found its way on his site and my service has never been better, don't be afraid to try it.
