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] Network lost during downgrade procedure. Any Help

T-Mobile Note 2:
How can I get data service back on the Note 2?
I cannot get 4G/LTE status on the Note 2 after the downgrade procedure.
I was on the latest OTA. I downgraded to 4.1.1 in order to be able to unlock the phone.
I flashed Factory Image T889UVALJ1 successfully. I noticed in the Flashing Instructions it states:
For Factory Image use Odin. – which I used
__-- Unzip the downloaded file and flash ".tar.md5" via Odin. Ignore "SS_DL.dll". Will LOOSE data and root. Back to Factory State.
____-- If you boot loop go back into recovery, do a factory reset, and reboot
I lost data service and I am having a hard time trying to get the network back again. I have tried flashing to the latest OTA, CM10 nightlies, and now currently on Jedi14. Everything works except Network. I put the sim card on a Galaxy S4 phone and the 4G/LTE service is there but no service on the Note 2.
I have searched and searched on how to get it back and nothing. Any help would be appreciated.

Anyone????
I have an extra Note 2. Rooted as well. Is there a file that I could use from the working Note 2 and place it in the non working Note 2?
For fun, I made a backup of the working Note 2 and placed it with the non working Note 2. Everything is there except network.

Do you have the correct APN setting?
Can you see your IMEI number?
Do you have the correct modem?

1st: make EFS backup (important! )
It is essentially a software issue. If you are on custom ROM, try flashing Agni Kernel (risky business). It should work.
If not, do a full data wipe / factory reset. Also format internal SD card. (Move your important stuff to external SD card and remove it for safety reasons)
Flash stock ROM via ODIN. The problem should be solved.
Press thumps up if you found this suggestion helpful.

@nilz_rokx - have you managed to sort out wife issue?
Think mine is the same issue. Updated from 4.1.2 Jellybean to 4.4.2 Kitkat. Now wifi will not switch on. Flick switch to right only to see it flick straight back.
Didn't really want to re-flash.

1st thing: go to stock recovery and do a wipe data/ factory reset and wipe cache partition.
If problem persists, only then flash the firmware.
Download link:
http://www.sammobile.com/firmwares/download/35296/N7100XXUFNI1_N7100ODDFNI1_INU.zip/
follow the instructions on the page.
Use ODIN 3.09 to flash the 4.4.2 firmware.
Report back.

No WiFi - EFS folder is empty

Hello everyone. Looking for some help. I suddenly lost the ability to use WiFi. I have 4g and cell service. When I try to turn on WiFi my phone reboots. After the reboot I get a message that the phone is in factory mode. I opened my EFS folder to make edits but it is empty. Can anybody help?
EDIT: I'm currently on 4.4.4 NH7 rooted.

Try flashing stock firmware, ShinySide has a link in general to download samsung stock firmware.
Pp.

I flashed the stock firmware. Wifi is somewhat working without rebooting. After a reboot i still get a message that factory mode is on and the phone turns off wifi. I also have to re-enter my wifi password to reconnect. Any ideas on how to turn off factory mode?
EDIT: Also when I trying flash anything in recovery I get a message in red saying unable to mount efs.

Try this Samsung Galaxy S4 : How to Get out of Factory Mode: http://youtu.be/d8dbrerUacw
Pp.

I already tried that. But for some reason my efs folder is empty. I'm guessing I need those files.
EDIT: Anyway someone can share their EFS folder?

Even after flashing stock NH7?
Try reflashing again, maybe open nh7 rom on pc with adb and copy content to your folder and reboot.
Pp.

I've flashed Shiny Sides modem through Odin. Then I followed it up by flashing his NH7 Stock ROM. No luck. The positive is that I have WiFi working again. The Bad side is that I get the "Factory Mode On" message on reboots and I have to re-enter my WiFi password.

What roms where you running before ShinySide's rom?
Where you on CM11?
Check your bootloader.
Pp.

I was on Phoenix Rom 4.4.2. Then I flashed Eudemony 4.4.4. It had some bugs so I restored back to Phoenix Rom. This is when my wifi and factory mode on issues began.

Try flashing Phoenix again, see if that fixes it.
Pp.

Panch, thank you for sticking around and trying to help me find a solution to my problem. I'll give re flashing Phoenix a shot later today and report back.

Loss of Data - No Sim Message

Good Morning Everyone,
I encountered a very weird issue last night after updating my table to 5.1.1 official. For the longest time, I was running the AOSP rom for 605 on my 607T. I was able to access Data and Wifi with no issues.
Last night, I rebooted to twrp, wiped my system and cache and internal storage.
Through Odin 3.07 - I flashed the factory firmware for 5.1.1.
Phone booted up and told me there was no Sim and would not allow the wifi option to be turned on because there was no sim. I thought this was strange as I have used it before on wifi when there actually was no sim card present. I pulled the sim out and put it back in - voila, i have wifi again. My Data connection kept the X through the bars though. I figured it must be something with the APN. I go to the APN Section and get a messages that this user (verified im set as the owner and only user) is not authorized to view APNs. I figured I would just create a new one - which I did and saved it. It would not even show the new one I made.
I ran into a similar lack of Sim visibility before when I first flashed 4.4.4 after running on an AOSP rom. I ended up flashing back to AOSP.
Has anyone else encountered this?

Reflash and try again, there was some mention of Data/Wifi errors. Also was the factory firmware for the 605 or the 607T? If 605 just flash the 607T firmware and you should be fine.

I flashed factory firmware for the 607T.
Going to try and reflash this afternoon when I get home from work and will follow up.
LOL I just read through the 605 thread -
http://forum.xda-developers.com/showpost.php?p=63147588&postcount=75
Looks like if you come from a custom rom - a double flash is required period. Glad I didn't actually set up my device last night.

Figured I would update for anyone who runs into this. Reflash did not work. Wiped everything and flashed a third time - no dice. I flashed back to 4.4.2 original factory image and used smart switch to upgrade back to 5.1.1
