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,

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] Sprint Galaxy Nexus; signal/3G issues

Sprint Galaxy Nexus
4.2.1
Not rooted
I performed a factory reset on my phone yesterday due to it bogging down and being rather slow. I never did a reset after getting the 4.2.1 update so I figured it was a good time. I woke up this morning, putzed around the house, and setup Tasker again. I laid my phone down for ten minutes while I got ready for work. Whenever I tried to wake my phone and nothing happened. I tried a few more times and the screen would not wake up. I pulled the battery, hard reset, reinserted battery and the phone wouldn't turn on. Then, I wiped the contact terminals (on the battery and the phone) and reinserted the battery and the phone booted up. However, since then I have had some major problems.
1. Power button does not always work properly. I have to press it several times to sleep or wake the phone. (Okay, not major, just inconvenient and probably unrelated to the issues below)
2. No data connection whatsoever.
3. In the data usage menu, there is no longer a data toggle switch.
4. Under the Network Mode option, LTE/CDMA produces absolutely no cell signal whatsoever. I have to switch to CDMA only. (WiFi works fine)
5. Toggling airplane mode, as some have suggested, does not cause the phone to connect to mobile data. Another factory reset did not restore mobile data. Rebooting did not restore mobile data.
6. All of these problems are true before and after factory reset. No new problems were created and nothing was exacerbated as a result of performing a factory reset.
I've been from one end of the internet to another looking for solutions to this problem and I have found that many are having a similar issue but toggling airplane mode or rebooting fixes it. Not the case for me. Most also seem to be having this problem after rooting. Again, not the case for me.
Any suggestions? I would prefer to not return the phone. Purchased from Radioshack and the 30-day warranty has expired. This is my second gnex already, as the first one's charging port broke. It took over a week to get this one from another store which graciously shipped it in to my store. There's also the issue of being broke and not really being able to afford another $30 activation fee on top of the deductible for a new phone.

Why not try reflashing the stock image and updating again to 4.2.1?

Not at all. You'd use Odin . Myself I have very spotty sprint signal in my home. Spoke to a corporate executive and they mailed me an AirRave free . Never have less then full bars 3g all around home. You should a- flash to stock using Odin following posts in sprint sextjon . b - call up and try to get an airavana.

Excellent. I will give it a shot at some point today or tomorrow and then let you know how it worked out. Thanks!

So, I restored the phone to stock. Signal is still non-existent on LTE/CDMA mode. Cannot perform Profile or PRL updates. Still no mobile data. I'm guessing hardware failure?
Also, on setup it asks for a SIM card. And at the bottom of the drop-down menu, it says "No SIM card|Sprint" or "No SIM card|No Service" depending on if I am in CDMA or LTE/CDMA.
Also, in the Status menu:
My phone number
Unknown
MIN
Unknown
PRL Version
Unknown
ICCID
Unknown
Seems a little odd to me.
Attempted fully rooting and flashing radios. No luck there either. It's also not wanting to update. Tells me my phone is up-to-date (connected via WiFi). Downloading Cyanogen now to see if it will work in the morning.

And while attempting to flash a new ROM, got the famous "can't copy anything to the device ever, under any circumstances" error.

Update: Got CM10 installed. Still "No SIM" error, no 3G, no data, no LTE. Found some more information on this No SIM error. Apparently a few others have had this same problem and in the end had to get a new phone.
Anyone know anything?

You should a- flash to stock using Odin following posts in sprint sextjon

I've been back to stock twice now. The first thing I did was flash to stock. Then I played around a bit and now I'm back to stock again.
Is there a difference between using Odin and Nexus Root Toolkit to return to stock?

Bump

Wow, one day and my thread is buried!
After battling for about a day, I got updated to JB 4.2.1, I can do profile and PRL updates again, but there is still no 3G/mobile data, and I still have zero bars on LTE/CDMA and have to use just CDMA. I am currently stock but the bootloader is unlocked, no root.
If anyone has heard any solution, please help. Also, if there's a difference between flashing to stock with Odin vs NRT, please say so.

Try fastboot flashing your LTE and CDMA radios again. As far as I know, fastboot commands do NOT require root. I had a similar issue.

Indeed, fastboot does not require root. I've flashed my radios several times now in various different ways. I even flashed different versions. I attempted again but with no luck. I have normal service when using CDMA but nothing on LTE/CDMA. Still no data, still "No SIM card" error.
Pretty sure I'll have to get it replaced. I've gone from stock JB back to stock ICS, rooted, CM10, back to stock ICS, rooted, back to stock JB unrooted, and flashed three different radios. I'm surprised I haven't managed to brick it yet.

UPDATE: Sprint is sending me a new phone, for free.

[Q] Lost IMEI now stuck in boot loop after ODIN to stock

Hello,
I'm having a lot of difficulty getting my Note II (SGH T889V) in working order . I'll try to explain the situation in an organized way. Thank you for your time and kind help!
Background
I have a Note 2 from Wind Mobile in Canada - SGH T889V. I got it 2.5 months ago. It was rooted, was running TWRP and I only loaded one ROM, flashed once, on it - 4.1.2 modified touchwiz ROM. Never once had an issue. The ROM was super stable and in great working order.
I got it unlocked about 2 weeks ago because I was visiting the states. When I got to the states, I put in a T-Mobile sim card which was working great for a few days. One afternoon during my vacation I was having slow data issues, so I thought to change the modem/radio from a Wind Mobile radio to a T-Mobile radio. That gave me 4G data speeds but killed my calls. So I tried to go back to the Wind Radio and that had my phone complaining that there was no SIM card. I went back to the T-Mobile radio and I got calling back but only 2G data.
My IMEI was corrupted - it showed up as zero. I left the T-Mobile radio on the phone when I got back. My home network wouldn't recognize me and thought I was still roaming.
Attempted Fixes
Tried a basic factory reset. Tried a different ROM. Tried wiping all internal data.
I got home and tried to flash to stock ROMs found on XDA for Wind Mobile phones. That didn't solve the issue. The IMEI remained null. The phone would reboot automatically every few minutes unless I turned Airplane Mode on. I figure the phone was looking for a signal and couldn't because of the IMEI problem.
So I looked around on the net and found a link about injecting the IMEI back using QPST (http://forum.xda-developers.com/showthread.php?t=1206275) but I couldn't get the program to detect my phone so I gave up and thought I could just get my binary count to 0 and stock and I'll just take it back for warranty.
I tried Triangle Away but I couldn't get the counter to go to 0 even with stock ROM and recovery. So I thought I would take it to a cell repair shop locally. I took it there and all they did was cause an issue on the phone to make it appear that KIES firmware upgrade failed so that it would be repaired under warranty. You would see a emergency firmware upgrade error the minute you turned the phone on. However, download mode still showed the custom binary count at 1, they didn't get it down to 0.
I spoke with my carrier and with Samsung anonymously, they said the counter would be an issue if I sent it in.
I came back home and tried doing the following, with the hopes of trying Triangle Away again:
1. Installed TWRP via ODIN and ran the restore on the backup I created in TWRP when I first got the phone. I restored everything including EFS. Phone boots to the stock samsung rom but it would restart automatically every few minutes. Even with Airplane mode on, it would still reboot on it's own.
The KIES error message doesn't appear anymore.
2. Went back to ODIN. It was getting stuck on SYSTEM in ODIN version 3.07 when flashing a stock rom. So I switched the USB port on my computer and used ODIN 3.04 then the flashes went through properly with no hang ups.
So I tried to flash a prerooted (http://forum.xda-developers.com/showthread.php?t=1975560&highlight=wind) stock ROM
and
also a basic stock ROM (http://forum.xda-developers.com/showthread.php?t=2061031), along with a stock recovery
Both just get stuck in a bootloop. I tried going to the stock recovery and wiping data, cache, factory reset several times. No luck - still boot loops. Wont go into the ROM.
I did not try "Re-partition" in ODIN. I'm not sure if that'll hard brick the device but maybe that way I can repair all of the partitions? - http://forum.xda-developers.com/showthread.php?t=860432&page=2
__________
Im hoping to get back into a prerooted ROM or stock ROM to try this Triangle Away Method - http://forum.xda-developers.com/showthread.php?t=2272966 to get the custom binary down to zero.
I tried to use the Triangle Away ODIN method but it doesnt go through in ODIN, it just gets stuck.
If I can get into the ROM without it boot looping or rebooting automatically- I think I can fix my IMEI like this person did - http://forum.xda-developers.com/showthread.php?t=2145967
Outcomes Im hoping for
To stop the bootlooping/ automatic reboots, then
1. To get the custom Binary count to 0 so I can send it back in for warranty to Samsung or my carrier, Wind Mobile. The binary says Samsung Official. - http://forum.xda-developers.com/showthread.php?t=2068156
or
2. To get the phone to working order so I can try this persons method - http://forum.xda-developers.com/showthread.php?t=2145967
The phone is still responding and it's still working with ODIN. It makes me think the issue is software or partition related and not hardware related per se. If it is hardware, I just want to get this phone back to Samsung but I need to unroot/clear the binary counter.
The phone has never been dropped or damaged physically. I've really babied the phone. This is my third Samsung Galaxy phone (I've had a Vibrant and S2x before this one.)
This has really ruined my week. I need my phone for work. I greatly appreciate any kind help or guidance. I know the collective genius here at XDA will be able to find a solution.
Thank you so much!

If you have flashed the tmobile modem you will now have to keep the tmobile one in order to get your phone to boot. Flashing a t889v modem will cause loops. Dont know of any way to get back to t889v modems.

Hey, don't worry, you aren't the first to experience this problem. Many users have reported that the T889V will bootloop with the T889V modem after flashing another modem. Many have also restored IMEI and service to their phones, so there is a solution. I don't have the specifics, but there are many threads about this problem with solutions. I have quickly searched for one and I believe it has everything you need to fix it.

Thank you. I'm going to give that a shot. I'll install CWM then install a T889 TMobile Radio to see if it boots.
I'll report back. Fingers crossed.

Thank you all!
I got the boot loops to stop by flashing CWM recovery, then flashing a TMobile Radio.
From there, I followed the QPST instructions of installing a QCN file on the phone to reenable the AWS spectrum. Then I used the IMEI creator and NV Writer programs and I was back.
Data seems alright, getting alright speeds on Wind right now. I just found my bluetooth a little hard to hear in the car this morning.
So with this process, I should stick with a Tmobile radio from now on right? If I flash a Wind/ T889V modem it'll boot loop?
Have you guys noticed any signal or performance issues after restoring the phone this way? I'm wondering if it's worth the trouble to get the custom binary counter to clear and return this phone for warranty. Seems to be working for the most part so far.
Thank you so much again! I thought I was going to have to pay $100 to get it JTAGed.

Glad to here your back and running.
I have a t889v using it on telus, and since I am stuck on tmobile modem I get lower phone signal but never loose signal. On a plus I now get lte speeds.

First day back it seems good for the most part.
Only issue I had was Bluetooth in my car would cut out at a high rate of speed (when I was on the highway). It worked really well while I was on local roads but once I hit the highway I couldn't hear the other side at all pretty much. I had to put them on speaker to hear them. They could hear me really well, better than before when I was driving on local roads.
Never occurred in the past. Could it be a radio issue? Signal seemed okay and I was able to continue the conversation over the phone speaker on the highway.

I noticed I have serious data issues when the network goes into HSPA+ mode. I get really good data for a minute then it'll cut out totally for like an hour. I tried rebooting, tried battery pulling. It seems the T-Mobile radio doesn't interface well with Wind's HSPA+ . I had full bars but the internet wouldn't load. It was pretty non-functional for most of the day.
It works decently when it's not on HSPA+
Tried switching to a Wind modem, went into boot loops. Went back to T-Mobile radio. Should I try a different T-Mobile radio?

how to fix your T889v if you accidentally overwrite the radio
If you get stuck with no IMEI, in my case, flashed omnirom 4.4.1 t0ltetmo, which uses Tmobile radio... it killed the Wind Mobile radio... restoring form nandroid did not help.
solution:
flash omnirom t0lte (not t0ltetmo) and your problems are gone!

t999 has bars but no calls or data, in all roms

So about 6 months ago, I decided to finally try out some custom roms on my t999 after running stock for over a year. I tried a couple of roms and stuck with cm11. Every thing was great until about 3 weeks ago. Out of nowhere, my phone randomly decides to drop connection to tmo towers. Sometimes i have bars and 4g symbol and sometimes i don't have anything. When I pull the battery and restart, I am able to connect to data, make calls, and send messages for a few minutes, but then i lose everything. Randomly throughout the day, I will get signal back for a few minutes but thats it. I flashed a touchwiz rom for now so I can use wifi calling, So that still works.
So I tried to flash a different baseband modem from DocHoliday77 and none of them worked. I also tried going back to stock following DocHoliday77s guide once again, but for some reason that does not work. I launch odin3.07, put my stock firmware in the pda section, make sure only auto reboot and F reset time are checked. I connect my phone in download mode, it is detected and i start the process. The phone restarts but gets stuck at the samsung logo screen. I have tried flashing different roms and none work.
I dont think its an imei problem because I got the phone direct form tmo with a contract.
Does anyone know what I might be doing wrong? ANY help would be greatly appreciated.

Did you factory reset after you flashed the firmware in Odin? That's the only way it will boot coming from cm.. You may just need a new sim if flashing to stock won't fix it.. And BTW T-Mobile doesn't do contracts

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
