Hello,
Please help if you can! I updated my Nexus S to 2.3.4 the other day, and everything was working fine. Today, the phone at some point lost the ability to connect to my network (Bell Mobility). I was out and about and was turning data off, and might have hit the 2g/3g toggle by accident, and seem to remember reading about that causing problems - though I have no idea if I did for sure (the sun was bright) and am honestly not sure what's wrong EDIT: when I go into wireless & networks\mobile networks\network operators, the phone will only recognize Roger's Wireless (and it was bought at a Telus store!) The UI still works fine, and I can still connect via wifi - just no way to get it to recognize Bell's network
As stated above, everything was working fine this morning - voice, data and sms all good. Here is all the info from my phone:
Android version 2.3.4
Baseband version NO DGSXXKD1
Kernel Version 2.6.35.7-ge383d80 [email protected] #1
Build number GRJ22
The bootloader is unlocked, and I had been running CM7 before flashing the manual 2.3.4. I'm not sure what to do. Tried re-flashing the manual 2.3.4 update.zip, and nothing. I know a very little bit about rooting/flashing (just enough to follow guides), and am wondering whether I need to re-flash a different kernel/radio/rom or something. I did search, and couldn't find anything that outlined my problem exactly (I do apologize if something is out there and I just didn't look hard enough).
Again, the phone was bought new at a Telus store, and found the Bell Mobility network out of the box no problem. Am hoping someone can help!
Thanks so much for reading, and if you are able to help.
Check your APN's to make sure the data info is in there I had to manually enter mine (bought phone from Telus to use on Bell/Sasktel's network) for Sasktel and bob was my uncle
Every upgrade i need to put them back in. No automatic for me, so i would start there
Menu - Settings - Wireless & Network - Mobile Networks - Access Point Names.
If nothing is in there, you need your APN settings. Talk to bell support for the info, and they should be able to help you over the phone (they support android even if they dont sell a Nexus S)
Cheers!
Thanks so much for your response, though I don't think that the APN's are the issue at all; they're still in there and fine. I think that it's the actual radio (or baseband), as the phone will not recognize the bell network, only the Rogers network (and it was bought new at a Telus store!)
I think that I need to re-flash the radio, and maybe the kernel. I searched to try and find the radio image for my phone, but haven't found anything clear enough for me to be comfortable to try - I've read time and again that flashing radios is one of the riskier things to do. I don't think that my phone is bricked (can still boot it up, and all of the ui works and can connect via wifi). Don't want to risk doing more damage.
Thanks again for your response though!
i think i'm having the same problem. i've manually upgraded to 2.3.3 then to 2.3.4. and then i put a sim card in - not used it as a phone before this.
i can get 3-4 white bars lit up but can't connect to any network. the bars turn green when wifi is active, but still can't connect ("can't connect at this time. please try again later" toast appears). not sure if the phone is borked, or if the upgrade wasn't that successful.
I actually have this same issue but using it on at&t in the USA...Really hope it isn't broken cause I have no way to fix it since i'm not in canada
Maybe check if the 2g box is checked in mobile networks. Check your apn settings and if that doesn't help try and flash another radio.

i'm unrooted, and don't intend to root. apn is fine as suggested above, and regardless of 2g checked or unchecked, still no connect
Rogers is the only 2G gsm provider, your phone may be stuck on 2G. If you have the choice, I would go back to 2.3.3 full stock and see if everything then works.

No. you are best to use cwm and restore a stock image for your phone

Your best option is to flash back to 2.3.3. Download rom manager from the market and flash clockwork recovery. Once in recovery flash the 2.3.3 .zip file. I saw it somewhere here but i forgot where I saw it. Hope that helps.

Try this http://devsforandroid.com/index.php?board=18.0
I'm NOT SURE if it'll work, but it's worth the try. Make sure to to wipe everything before you flash. I'm not responsible for any damage this may cause. But I hope this helps you out.
If anyone wants to chime in and correct me please do so.

Or if you're not comfortable flashing the stock 2.3.3 rom maybe just try and flash back the xxkb2 radio which I believe was the stock baseband for Rogers, telus, Fido and bell. I have the .zip file for you to try and flash through CWM if you need it. Otherwise you can find it somewhere here aswell.

i'm not looking to root nor use any 'hacks'. i don't trust them.
under the battery, the phone is just a i9020. no letter afterwards.
Flashing a ROM doesn't require root, it requires unlocking the bootloader, which Google officially allows you to do that. You can unlock the bootloader, flash 2.3.3 ROM, then lock it as if it had never been unlocked. Just keep in mind that unlocking resets to factory default and wipes your SD card clean, backup before you do it.
Ahhh yes, I had same thing except with Telus I fixed it once, but the second time I could not get it to work, do this, flash this radio
http://forum.xda-developers.com/showthread.php?t=1044261
it is the stock radio your phone came with, then call up bell and get them to "repush" your sim card... hopefully you will see your network again.

if i unlock to then flash, don't i need a radio package? how do i know which one to use?
also, would i be able to do a full compile of android and flash that?

It depends on which ROM you flash. I flashed the official 2.3.3 ROM, it contains the radio image, it'll flash it as you apply the update.
Do you remember which baseband version it came with out of box? That should give us hint as to which radio applies to your phone. I think there are really only two types of radios used except NS 4G, 850/1900/2100 (i9020A radio) and 900/1700/2100 (i9020T radio). You can ask your service provider or check out their website which band you are running on.
Back to flashing ROM, I just realised you don't even need to unlock the bootloader if you are flashing Google signed files. You should most likely be able to flash a 2.3.3 full ROM, then flash the 2.3.4 update file. But if you find the 2.3.4 full ROM, that's even more convenient. I saw a full ROM on the forum, but I that was for i9023 or i9020. Not too sure, maybe others know.
For the Canadian carriers, as stated before, Rogers is the only 2g (edge) carrier all others (Bell, Telus, Sasktel) are 3g (HSPA). go Settings>Wireless & network settings>mobile networks and ensure "Use only 2g networks" is not selected.
If this does not work flash the KB2 modem, the other modems may lose 850mHz spectrum which could be causing your grief.
Solution!!! (At least this worked for me!) - Didn't have to flash anything
Hey all,
I apologize for not posting this sooner, but found a solution that worked for me, hope it might work for others experiencing the same problem.
**PLEASE keep in mind that though this worked for me, I don't know if it will work for you (maybe it might make things worse for some people). Especially keeping in mind that I DON'T KNOW FOR CERTAIN what originally caused the issue for me, nor what specific factors (rom build, phone model, radio image, etc) might have contributed. As well, I am on the Bell Network. USE ANY OF WHAT'S STATED BELOW AT YOUR OWN RISK. Disclaimer stated, read on...**
In the dialer, I punched in *#*#4636#*#* and then from the menu that popped up, selected Phone Information.
From there, in the Set preferred network type: drop down menu (scroll down a little, you'll see it) I selected GSM/CDMA auto (PRL). **Again, remember that I'm on the Bell Network in Canada. Should you be trying this, these settings might not be for you. Again, AT YOUR OWN RISK**
Then, still from the Phone Information screen, I pressed menu button (the hard menu button on the phone), and then chose the Select Radio Band option. From there, I believe I selected Auto, though I may have selected USA (It's been a couple of days, and I can't remember, I apologize).
After that, went back to the Phone Information menu, and pressed Run Ping Test. It seemed to show all of the necessary (and appropriate for my network) settings as ok, and... everything worked!!! Full network connection as before!
Hope this might help someone else! Keep in mind that I'm not sure what caused the original problem; I do believe I remember pressing the 2g/3g toggle, and also remember reading somewhere that this can cause problems. Specifically, that it stopped peoples phones from going back from 2g to 3g - in my case (Bell Mobility) there is no 2g network to drop down to, so if it got stuck on EDGE mode, it probable looked for the only local carrier with a GM EDGE network, (Rogers) and got stuck there. Not sure, but maybe this is what happened. Any wise folks out there that might be able to confirm/offer insight?
Anyhow, thanks so much for all the responses and offers of help!
Hi,
I recently decided to flash a jeallybean ROM since most of them are getting really great and we don't have any word on the official update. Unfortunatly, I'm now unable to get a data connection on my HOX. It's the rogers version which I unlocked and I'm now using on the Bell network. Before flashing, LTE worked fine with the stock sense ROM, but now I don't have any data at all.
ROMs I've tried :
AOKP, MIUI and CM10.
I've tried to : set the data connection to GSM only, nothing, to LTE only, nothing, to WCDMA only, nothing. I've tried all the APNs I've found (pda.bell.ca, pda2.bell.ca, inet.bell.ca). On AOKP it sometimes said "Error while searching for network". WiFi, texts and calls work fine.
If anyone could help me, it would be really appreaciated. Otherwise I'll just revert to Rogers ROM. Thanks alot!
I cant offer any help, but I'm having a similar issue recently. I was on a nightly build of CM10 (from 10/06/12 I believe). I upgraded to a newer build (from 10/10) and I get no data over cell. I flashed it back and things were fine.

Before flashing jelly bean roms you need to flash a sense rom then do full wipe and install cm10 or aokp..

I have the exact same problem with my SGS using the X-bean 3.0 rom.
What's the best solution? Is it because I used to Cwm?

Every device has its own nuances, as do various ROMs. So I'd advise posting this in the forum specific to your device.
Still no data connection.
I am having the same issue with my AT&T One X phone.
The phone was running 2.20 before it was unlocked/rooted. Installed TWRP, was a noob and forgot to save a backup, fastbooted the boot.img, flashed AOKP and CM10 successfully. With both of these ROMs, I could not get internet to work via cellular connection. I have tried everything with the APNs (even had AT&T help me setup APN settings) and still no mobile data connection. I can still receive/send SMS/calls, use bluetooth and wifi, just no mobile internet.
I'm not entirely sure what to do next. I attempted to go back and flash the UrDroid 4.1 Stock Sense ROM, but after fastbooting it's boot.img and attempting to flash with TWRP, I got a signature verification failure. Got scared and restored back to AOKP (I remember to make a backup this time.)
Thoughts? Sorry for being a noob.
Are you in an LTE area?

I am in a "4G" area (HSPA+) but I am also a hour drive away from LTE. I have tried APNs for both, but AT&T recommended I stick to the LTE APN. AT&T had me go to Settings->More->Mobile Networks->Network Operators and the phone just sat there searching without finding anything. I just did that above operation again and it found AT&T and I selected it. It spins on "Registering on AT&T..." for a few minutes and eventually errors out "Cannot register on this network at this time."
Have you tried switching off LTE by selecting "GSM/WCDMA Auto" in Settings?
I've had data problems on certain ROMs, where turning off LTE got the HSPA+ connection working.
In that case, it was probably a base of build.prop not playing well with AT&T's network. Although I would think the ROMs you mentioned would have these issues worked out at this point (and for some time now).

When I switch to "GSM/WCDMA Auto", it immediately switches itself back to the LTE setting. This is concerning.
Posting my query here as instructed since I'm a newbie account and cannot reply to a Dev thread.
Following the thread here: [ROM][4.0.4][P7320/T][CWM] Arlic's ICHI ROM 1.2, compatybile with P7320T!
I have a Galaxy Tab 8.9 LTE from Hong Kong on the ChinaMobile network. (GT-P7320)
- I made sure to backup my original stock setup in CWM before doing anything.
- Then flashed the Arlicc's ICS rom sequentially as instructed (1.0 > 1.1 > 1.2)
- Everything seemed to install fine with no errors.
- However after the intitial wipe to factory conditions, load and new device configuration, I noticed that although I had signal, the data connection never went above "E"
- I checked my APN settings and made sure 4G/LTE was enabled (APN settings)
- No matter what I tried, couldn't get my LTE connection back, couldn't even get 3G back.
- Baseband reads as P7320ZHLC1
Since it wasn't working, I go to restore my original rom in CWM > Restore
- After restoring and then resetting everything back to factory conditions, I find I get no signal at all!
- Go to configure mobile settings, it says SIM card not detected?! (Haven't moved or dropped the unit, or touched the sim slot)
- Baseband now reports "Unavailable"
- The whole device also reboots approx every 30 seconds.
I think my backup is borked. =/
- I flash back Arlicc's rom and at least everything runs correctly. Apart from the lack of data signal.
From memory, I think my baseband should be P7320ZHLC2 for Chinamobile, but I can't be sure.
Unfortunately, none of the Hong Kong stock P7320 firmwares are on sammobile.
Help?!
Hmm... don'tcha just hate it when this happens?
..at some point between me putting the Tab down for dinner and then coming back to it again the 4G suddenly started working.
There are only two things I can think of that I did differently this time.
- I only wiped the caches / factory reset before updating the firmware, I didn't do it afterwards this time. Booted straight in after flashing the ICS rom.
- I connected to the home wifi to see if it would grab any extra settings out of the ether... non of the software updates reported anything downloaded when I put it down for dinner.
...yet when I came back and rebooted again. The 4G icon came up almost immediately?
Strange.
I'm having an odd issue. I've been running the latest Hyperdrive ROM release on my S3 for about a year now, but I can't stand Touchwiz ROM's so I've tried flashing AOSP ROM's such as CM, AOKP, even Beanstalk. I love all of these ROMs for tons of reasons but I keep running into the same problem, everything works great but I can't receive mobile data. My mobile network state is Disconnected and I have no idea how to fix that. I can text, call, and connect to wifi fine, but no mobile data. I've backed up my EFS but I'm not sure that's connected to the same thing. I have the network set to "CDMA/LTE" (would be more specific but each ROM has it different), but for whatever reason the APN settings are inaccessible. The menu option is clearly there but I cannot open it to ensure I'm using the LTE APN. I decided to give this another go yesterday, and still no dice. However upon restoring my CWM backup of Hyperdrive, I have now lost 4G and am stuck on 3G. My network type now shows eHRPD and while I can access my APN's (I was always able to on Touchwiz ROMs) I can tap on the Verizon LTE APN, but it seems to make absolutely no change to the actual APN. In fact when I reboot it it defaults back to eHRPD all over again.
So, 1. have I somehow screwed myself over? and 2. what am I missing with AOSP based ROMs?
Thanks for any and all help.

I would try flashing a stock ROM such as the one on ScottsROMs.com
The 4.3 stock rooted, OTA disabled, UNlocled boot loader and no Knox.
See if you can get data with that. Firmware for the radio may have gotten messed up, and this would re-write that data (long shot, but worth a try). Another option would be to re-flash the radio maybe.
And now that I think of it, which radio are you on? MF1, ML1, NE1? Because I think I read somewhere that certain ROMs require a certain radio newer than _____ (don't remember which radio).

Thanks for the help. I flashed a 4.3 ROM as you suggested, and no difference. I then chased some threads around and decided to just factory reset it as if I was going to return it. Still nothing, I get 3G, not LTE. I was using MB1 before I flashed an AOSP ROM, at which point I flashed the MF1 firmware and then the ML1 modem. That did nothing to fix my issue. I'm not quite sure what else I can do at this point.

Hmm... ML1 should be new enough.
That's a bizarre issue.
For me, I mainly get 3G. It seems as if either Verizon pulled some LTE towers near me, or my data antenna doesn't have very good contact. Maybe you're having the same issue.
Do you EVER get 4G? Or literally never?
This is consistent across every CM14 ROM I've flashed. I am upgrading from CM13.
The signal bar at the top is blank as in "no service", it attempts to reconnect and show a signal for a split second but then goes back to "no service" again. When I remove my SIM card and reboot the problem simply vanishes, but of course I can't get LTE
Firmware: PCA
Recovery: TWRP 3.0.1.0
I have tried running the ROM stock with no data restore and I have tried flashing APN settings from this post.
I at first thought it was a CM14 bug but then I read that others had no problems with CM14 ROMs.
Assuming you actually have a SM-G900P (since a lot of people ignore that little detail) it's probably a matter of Cm14/14.1 doesn't appear to be wholly happy with anything other than the latest baseband, which is now PK1. To get it, just reflash to stock with Odin and then poke at the thing until it gets the two OTA updates that will bring you up to PK1. At that point if you like you can poke at the controls to update the PRL and Profile (just to be sure everything's good) and then let me suggest you make a call or two and/or send some SMSes to be sure you didn't mess something up when you tried to change the APN settings one almost never needs to touch, and then flash TWRP (or whatever recovery you use) right back in and sideload the Cm14.1 nightly and open-gapps for 7.1. Also, you will need to do a factory reset after upgrading to 14.1 or you'll get a wholly different set of misbehaviours out of the phone (trust me... I deliberately cut corners through multiple rounds of reflashing to find out what symptoms to look for). One of the more endearing failures can be no soft keyboard, nobody wants that.
I had a bunch of weirdness happening (including completely non-functional GPS) with CM14 a few days ago, and since the changelog doesn't seem to show anything addressing the screwy problems I had, it hints very strongly that people will need to update to PK1 before they can expect the device be reliable.
OH... and don't try and enable Adoptive Storage if it asks. The performance is abysmal for some reason (around 2Mb/s on a Class-10 card that otherwise hums along at 14Mb/s) and it will make any apps that are trying to use storage run like crap.
So people have it working on PK1? Has anyone had it working on PCA?
Edit: Odin restored PK1, it didnt want to boot after the reflash. I installed TWRP and restored a PCA Backup, updated PRL and profile. I flashed a cm14.1 ROM and still had the same issues.
It also didn't wipe my internal storage when I ran odin, which I remember it doing in the past.
Worked great on my S5 900P
Gracefully I got it to work on Resurrection Remix. Idk if it was the APNs or just more stable ROMs.
I booted RR stock w/o gapps, I went to enter in the APN settings using this site and it just magically worked after I entered in only the first line. It's hard to tell if it was because the ROM found out how to connect or if the first line of the APN settings triggered something.
