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] Error 1500

When my phone boots up, it tries to do a "Hands-Free Activation"; it fails and then says "internal error 1500." I still have service and can make calls, but I can't use mobile data or use the internet. I need to fix this. Any help?

Bump, need help on this issue as well.
I'm on sprint version, I'd mistakenly pushed a N7100 Note 2 rom instead of the 900 sprint model, and even with a complete restore of the stock rom, mobile data is borked.

Same issue here any fix's yet ?

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)

[Q] LTE issues after cm12 (virgin mobile a5_chl)

So as the title states I have the virgin mobile a5_chl variant and after flashing cm12 (build 05052015) I can no longer (or at least hardly ever) gain LTE signal back, no matter what ROM im on. It comes across saying I have no service and no signal and I can't text or call when trying to use LTE.
I have done the following to try and fix:
1. flash apn fix (obviously)
2. restore stock backup
3. try a different rom
4. completely RUU back to stock.
I believe the issue lies somewhere within the HtcOMADM_SPCS.apk but I'm not 100% sure about that. According to any thing i've found the HtcOMADM_SPCS.apk is the "vDM client" that allows for profile updates (when i try to do a profile update it either says vDM client has stopped responding or the the profile update could not be completed). I've tried uninstalling and reinstalling the HtcOMADM_SPCS.apk but that only provided a fix once and when i rebooted my phone I lost signal again.
I'm pretty much at a loss as to what to do as virgin mobile gives me the usual run around that they are "having tower issues" so I'm hoping maybe someone on here can help out. If you need any further information please ask and I'll provide, I tried to be thorough when creating this thread. Thanks for any help.

BUMP / Can someone from VM USA upload a copy of the HtcOMAD_SPCS.apk it can be found in system/app/HtcOMAD_SPCS. It would be very much appreciated if you could

Same exact issue

Pixel 2 XL cellular data issue with any custom ROM

Recently i have entered some state in which mobile data is busted on my phone. I have tested multiple android pie roms to find the same thing in each. When i flash the latest stock android (PQ1A.181205.002), mobile data is fine. In this broken state i can see the signal bars with a little 'R' by them (notification on lost mobile data connection Data roaming is turned off. tap to turn on). Every time i navigate into Settings> Network & internet > Mobile Network > Advanced > Carrier Settings. The screen will flash and take me back to Mobile Network, this happens with every custom rom tested. The app SprintDM tries to set up the phone 5 times and then fails. Phone codes seem to have no effect. the code 4636 will allow me to view current info in which it says mobile data disconnected. It doesn't appear to matter if i connect to wifi and allow the basic stock apps to update first. Reboots do not help. I even tried flashing the modem and radio for PQ1A.181105.017.A1 and OPM4.171019.021.R1. I can also say the phone app shows a message "This device is not supported and phone calls may not work correctly". Phone calls work fine. Previously i was running LiquidRemix (10.0.2) just fine, everything working. Randomly mobile data died so i tried a update to LiquidRemix (10.0.3) and still busted. Tested multiple other PIE roms to find the same. And again if i flash any stock firmware mobile data is fine. Anyone else see this or have an idea of how to fix this for custom roms?

I rooted my pixel2xl yesterday and installed Havoc OS.
Today I was out with my family and was trying to navigate via Google maps and it continuously displayed error "try again"
Status bar was showing lte connection then I tried opening chrome and was unable to use mobile data even if it being on and active.
I am planning to move to Stock again tomorrow

vipulkarkar, did you find out any other additional info on this? I went back to stock and everything is fine but would very much rather be running a custom rom.

Just seeing this post, fortunately, I've not run into this issue on stock or custom roms ... What I do run into, on stock or custom roms, is when I leave my house, with a T-Mobile CellSpot, I tend to switch to 3G or H+ in an LTE area. I sometimes have to cycle airport mode a couple times to get LTE back.. So odd and annoying!

Is there something we Sprint users could do to help the devs include Sprint connectivity in their roms? Like provide a nandroid backup of our device or ?
