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?

No service after reflashing to stock [Solved]

Had my nexus rooted since day 1 and never had any issues. Lately i've been trying to use Barclay's Pingit app which doesn't work on rooted devices. So i reflashed to stock through the galaxy nexus toolkit. I did get service on the stock rom, but i've since tried a nandroid restore of my CM10 and it appears to have screwed something up. First off, the restore completed in 4 seconds, so it obviously didn't work. I'm using TWRP if that makes any difference.
So i tried a wipe and flash other roms, but still no service. Even after going back to stock, still no service. I'm assuming the botched nandroid restore has possibly damaged my radio somehow? I did try to flash another radio, and it flashes ok, but still no service.
APN settings are fine. All i get though when i try to connect to a network is "Can't connect to this network at the moment, please try again later".
I'm on 3 UK. Tried connecting to other networks, but still the same issue
Just tried flashing a new radio through fastboot, flashes fine and shows up in baseband version, but still no service...

Have you tried getril app? If your radio interface layer doesn't match it can fix it.

Yeah i tried it earlier, no luck.
Just tried again to make sure, still nothing

I have had some bad flashes with twrp. If I were you I would try cwm and then flash a new ROM.

Op, do you still have your imei? Try another simcard have you?
Sent from my i9250

Yeah i've tried several new rom flashes through CWM.
@bk201doesntexist - Yeah the phone has an IMEI in the status menu. I'm wondering if it's blocked since my provider accidentally cancelled my contract a few months ago, and i didn't say a word
Scrap that actually, apparently Three UK can't block IMEI's for some reason...
Funnily enough, i tried a sim card from another carrier and not only did it not connect to any network, but now when i go to search networks it just says "Error while searching for networks".
Edit - Called my network provider, they said my IMEI was wrong. At the minute it starts with 0049, which it shouldn't apparently. I dunno how this got changed in the first place.
Ok, so i've looked into the imei 0049 issue and it's starting to make sense. I looked in the /factory folder and it's empty, well apart from lost+found but it's empty. I assume the only option is to send it off for repairs? I do still have a nandroid backup on my computer and it has efs.ext4.win on there. Gonna give that a shot.
Edit 2 - Ok so I updated TWRP as my version was 2.2. Attempted the nandroid restore again and success! Got my voice and data back!
Thanks for the suggestions, its been a stressful day and hope this can help somebody else in a similar position

Yeah i forgot mentioning the fake imei thing. I was thinking about the /factory partition being null, thats why i spoke of imei.
Please edit the thread title to include tag [SOLVED]. Thanks.

[Q] Initially lost signal, ended up with unrecoverable boot loop

Hey guys,
This thread stems from this post: http://forum.xda-developers.com/showpost.php?p=39594591&postcount=18
I'm gonna spare you the trouble of having to read that thread by summing it up for you:
- T-889V, running Jedi x12, had to pop out the sim to try it on another phone.
- Once popped back in, my phone lost all carrier connectivity. At first the signal icon looked like a "forbidden" sign. Then, after a little while, I get service bars, but no connectivity indicator.
- IMEI used to show up, but I still didn't get connected. Used my sim in a different phone as well as a different sim in my phone to rule those 2 out. As expected a different sim in mine didn't work.
- I go back to stock using mobile odin. My IMEI is now unknown, obviously I can't connect to anything and on top of that the phone reboots every 1 minute or so.
- I flashed some other rom I had lying around. My IMEI is back, bootlooping stopped, however I was still unable to get any service.
- Try a different version of stock with mobile odin the and I'm boot looping. This time I can't get into recovery at all.
- Finally I try desktop odin with a couple of different stock images, and I'm still bootlooping (reboots right after the Samsung logo). Recovery works fine.
I would send it back but I'm worried about my flash counter being 1, and my system status being "custom". I am completely stumped. Absolutely any ideas are appreciated.

Sometimes after flashing stock you have to wipe data factory reset to get it to boot. Just a thought.

Thanks for the idea. I have tried that

Have you tried flashing back whatever modem came with that Jedi ROM, along with either the stock T889V or an N7105 ROM?
Still getting bootloops?
In other words, get to a no service and no bootloop situation, and look into restoring NV items with the appropriate Qualcomm compatible programs.
Sent from my SGH-T889V using xda app-developers app

But do you think it's possible to escape the constant bootloop? Right now I'm a little worried about flashing anything that will increase the counter, as I don't know if I'll get to run triangleaway ever again...
By qualcomm compatible programs you mean those 2 little tools that let you extract/write an IMEI as well as generate it as a text file?

The solution should be the same as the one I used for fixing my phone: using NV reader writer to rewrite correct stock settings along with your IMEI.
Warranty centres don't care about your exact counter, only if it's 0 or not, so flash away until you fix this. My counter was well over 30 when I finally did.

And finally you have paranoidandroid or back again in the previous rom? With a little search in the forum i found this "Hey...I found out why I didn't have service and was able to fix it. When I had flashed AOKP, there is a setting in the Mobile Networks screen to change the CDMA subscription to RUIM/SIM. Somehow (probably playing around) I changed it from the NV to RUIM/SIM. THEN, I nandroided back to stock, and had no service. As far as I know, that CDMA Subscription option isn't on the STOCK ROM...so I was baffled. Good thing I remembered what I did."
Try it and report..!

i'd recommend that you flashed again your previous rom to see if it is rom related or not. I ve read somewhere that some people had problems with the signal when flashing aokp.

i going to take it to the samsung cc....... lets see what they will say about this problem

I am suffering a very similar and strange problem. I have a Dmc3 deodexed and rooted Rom with NEDLK1 baseband (3 ITA operator) since 3 months. I have done nothing special (no new apps nor flashes) in the latest weeeks. I have never flashed any other ROM. But 2 days ago I saw NO service. I have correct imei, could even surf the web but no telephone functions. Rebooting the phone did not work.
I thought of a SIM card issue and yesterday I asked my operator for a new sim. While I was waiting the new sim to be enabled, today I pushed in my Note 2 another SIM by another operator. After some hours I had the same trouble with this SIM.
So the problem is the Telephon. I don't know if hw or sw, but there is an issue.
Now to see what may be, first I changed the baseband Modem and flashed a stock XXDLK7 and inserted the new Sim inside. Now I will wait and see.
In case of continuing issue, I will try and go back to full stock operations.

Hello guys. I had the same problem, and it was a hardware problem. The solution is really simple: put onto the left of the camera, inside the chassis, a small piece of papero of 3 mm. It's enough to strenght the connections of the flat of the SIM card connectors to the motherboard

D850 cant connect to GSM. stuck at "No Service"

We had a few hours network outage due to security reasons. But my G3 didnt recover when the outage was over and is still stuck at "no Service" even after several reboots, clean flash of cloudy and restoration to stock using nandroid. It was working just fine a night before. I have tried restoring Stock from nandroid but still no luck. I have tried different SIM cards too but still no connectivity.
*#06# shows proper IMEI number.
Any clue what might be wrong and how to go about fixing it ?

Update ::
OK So I looked around. my IMEI is correct. my wifi and bluetooth mac addresses are ok. but my baseband is shown as unknown. So i flashed a modem from here for v10D D850 and now I am not getting "No service" but still not getting any network

My suggestion is flash stock Rom with kdz or tot method. Look under general section and return completely stock.

OK so I am back to stock using TOT method. I have my IMEI, baseband and MAC addresses intact. Now it doesn't say No service rather it keeps on searching for signal and catches some from time to time but loses it again in a jiffy. Sim Toolkit is working fine so I assume SIM jacket isn't the trouble maker here.
search for signals :::: get a lock on :::: lose the signal :::: repeat
Any clues ?

Turn on airplane mode on and off. Factory reset your device from settings menu. It's a weird problem. It must be fixed after tot method.

Are you using it on At&t? Maybe sim gone bad or imei blacklisted by accident.

Which ATT APN are you currently using?

I'm actually having this exact problem to right now, I flashed back to stock and I still receive no data. I've tried nextgenphone APN and the PTA APN, I also checked my IMEI and it's fine to.
Edit:
I'm using an AT&T LG D850
When I put the sim card into my Moto G, it picks up 3G and works.

Ok so after having my go at the phone i had it given for repairs. The guy said he has replaced antenna multiplexer ic which has solved the problem.

I am experiencing the exact same issue but with a D855.
I decided to go from stock to CM12.1. This didn't end up working. Stuck on Bootloop. I also tried Xenon HD and had the same issue. So I came back to stock. Now having this issue.
What I did was flash from 5.0 to 4.4 so that I could root. I was unable to on 5.0.
Then I rooted using LG One click Root.
Then I flashed the latest TWRP
Then I did a full clean in TWRP and flashed CM & GAPPS (same with Xenon)
When this didn't work, I flashed to stock using LG FLash tool.
I tried both the KDZ and TOT methods numerous times, also tried to re-flash CM & Xenon and had the same issues.
I also tried flashing stock 4.4 and 5.0 roms and still the same.
I have also done multiple factory resets after flashing.
If anyone out there has solved this issue without sending their phone away, please advise as I am at my wits end and without a working phone.
Thanks
