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
Sent from my Nexus S
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!
Hello All,
I am a avid XDA reader and follower. I don't post allot, but do allot of reading and tooling around. That being said I have read and tried many different option for my issue.
Device: I9020T on T-Mobile US
Issue: "Baseband Unknown" / No Cell Service
-Under Settings/About Phone. My Baseband version = Unknown
-My signal bars are greyed out with a small "X"
-Everything else works, wifi, camera, ect...
When in FASBOOT the following is listed:
-Product Name: Harring
-HW Version: REV 11
-Bootloader Version: I9020XXKA3
-Baseband Version: I9020XXKD1
-Carrier Info: EUR
-Serial Number: This matches the on on my box
The issue started after I installed one of the latest KANG builds of CM7 nightly builds. I also had flashed [KERNEL] [gpl] NS/NS4G Trinity (E)UV and OC 2.6.35.13/.14 BFS .404, CM7 + m(any) roms.
This combo had been working good for at least 8-10 hours until I was listening to music through PowerAMP, when all of the sudden the music sounded like a CD skipping. The screen was unresponsive and no buttons or combo of buttons did any thing. I hesitated but eventually had to pull the battery.
When I powered the phone back up it hung at the trinity boot logo and just froze. After several reboots with the same results, I resorted to flashing a different ROM through Recovery. That's when I noticed the issue at hand.
As I was typing this I noticed it was strange that fast boot listed my carrier info as EUR??? Is this maybe because I'm currently running [ROM] Gingerbread Peter Alfonso (GPA17)? I flashed the ROM listed for my phone.
Anyways here is what I have tried:
-Flashing a NANDROID of stock 2.3.2 through Recovery
-ADB/Fastboot flashing the various radios for my model
-Flashing radios through Recovery
-Flashing ROMS meant for my phone with radios in them
-Even found everything I needed and used ODIN to get back to factory fresh!!!
So sorry for the long post but I am out of ideas and am thinking it my actually be a hardware issue.
Thought I'd throw this out to you all and see if there are any ideas I may have not tried.
Thanks in advance for any ideas or advice.
can you install a stock rom back onto it? There is a baseband selection mode that you may have to do.
http://forum.xda-developers.com/showthread.php?t=1116884
1. Go to Dialer. Dial *#*#4636#*#*
2. Go to Phone information. Choose the preferred network to
"GSM Auto PRL" or "CDMA Auto PRL" or whatever you have.
3. Scroll down, deactivate and activate Phone Radio.
4. Press Menu button.
5. Select Phone frequency, then choose your country.
6. In the previous menu push the Home button to go back to Homescreen.
7. Reboot.
(By Brainmaster)
Ive had to run this a few times depending on radio and rom.
after many trials I am sticking with rooted stock.
Wow that is defiantly a menu I have never seen before.
It doesn't let me select any of the preferred carrier option. When I tap on GSM auto (PRL) it just closes and defaults back Unknown.

Ya, I think it is. RIP Nexus S. HTC Sensation here I come.
after you select gsm auto you hit the menu button on your phone then select the carrier. I know its not labeled what it is on the walkthrough but its similar. not phone frequency but like signal or something. then yuo jsut select usa.
reboot and it should find whatever your service is on its own.
have you tried going back to stock rom? I used this version to go back when i thought i bricked out my phone and its been great. I think my friend used it too but he wont admit he used somethign i gave him.

did you happen to flash the ns4G version of [ROM] Gingerbread Peter Alfonso (GPA17)? that would make sense then why you dont have any signal, considering your on tmobile and the ns4g is sprint.

Sorry to hijack the thread, but I have the same problem as the OP and I think this is exactly what I did wrong.
I wasn't paying attention when I updated Cyanogenmod and I chose the Nexus s 4G instead of regular Nexus s.
Ever since then my baseband has been "unknown" (except in fastboot, where is shows as KB3 (which I updated to as one of my attempts to fix it).
I have gone back to stock, no change. I have updated the radio, no change.
I have no idea what else to do. Does anyone have any ideas??

I've wiped user data/factory reset a few times now. Is there a higher-level format option that I should be using?
I thought for sure that going back to stock (based on these instructions - theunlockr.com/2011/01/20/how-to-unroot-the-nexus-s/) would work, but no such luck.
I find it perplexing that the baseband shows in fastboot, but nowhere else. *#*#4636#*#* shows radio off and network type unknown, settings/about phone/ shows baseband version unknown.
I tried different methods that I've found online over the weekend, but nothing has brought my radio back.
I am certainly open to suggestions!
I'm going to provide as much additional information as possible.
I have a Nexus S I9020A, running on Fido (Canada).
My initial problem stems from when I updated to cyanogenmod 7.1 from 7.0. My first (and likely biggest) mistake was not making a backup. Oops.
I think I accidentally chose "Nexus S 4G" instead of "Nexus S". As soon as I did that, I stopped getting any cellular voice or data connection (wifi continues to work fine). Under Phone Information, it said it was a Nexus S 4G.
The phone locks itself into airplane mode now. When I try to turn airplane mode off through the settings menu, it hangs. When I hold down power and choose "turn airplane mode off" it seems to work, but then I still get no signal.
I have pushed it back down to stock. It now remembers that it is a Nexus S (not 4G), but it didn't help the baseband problem.
I have tried to reflash the baseband. no effect.
I called Fido and got them to "repush" the SIM card. No effect.
I am humbly appreciative of any and all help that anyone can provide!

Thanks! This is similar to some other threads I saw on the android forum (and elsewhere on XDA).
I'll try this when I get home (and get to a reliable wifi signal).
Wow! I haven't looked at my post in a wile. Hopefully you all are getting some resolution to these issues. I ended up calling Samsung and they agreed to fix my Nexus under warranty. They replaced some parts that I can't remember off the top of my head, but it should arive at my door tomorrow!!!

Hmmm bad news... my efs folder appears to be empty. Now what?
A very frustrating day... Thought i would have it fixed pretty quick, alas....
My efs folder is empty. I guess that explains the lack of radio, but it appears that i might need to send the phone to Samsung to get the efs reflashed. Is there a way to write it back myself? Ill look tomorrow i guess.
Here is some more info:
I just tried to update to 2.3.6
Clockwork mod is giving me an error message:
Assert failed: getprop("ro.product.device") == "crespo" || get prop("rp.build.product") == "crespo"
E:error in [filename]
(Status 7)
Installation aborted
Not sure if that helps but it's another piece of thepuzzle hopefully.
*sigh*
So it appears that I need a backup of my /efs folder in order to fix this myself (which I do not have).
I know what my IMEI should be, however I have no idea if it is even possible to take someone else's backup and alter it the proper IMEI.
I fear my next option will be to submit it for repair at a Samsung repair shop (and be without a phone even longer )
I just flashed for the first time and everything seemed fine,
till (after flashing the Gapps) I noticed my phone won't connect to a mobile network.
WiFi is working, only Mobile Network is defunct.
I tried two different SIMs, both worked on other devices but not on this.
I may be wrong, but I don't think a locked SIM is my problem, since I don't see any SIM-with-an-exclamation icon icon as described in other posts.
Detailed Description:
Lock-screen shows the text "(No Service)".
When trying to search for a network in Settings > Mobile Networks > Network Operators, it says "Error while searching for networks".
Additional Info:
Device: LG P-500.
Flashing toolchain: Gingerbreak; ROM Manager + CWM.
Flashed: Stable CM7.2 from CM's site;
Gapps from Goo.im.
Baseband: P500-M76XX-V10f-FEB-18-2011-XX.
(Taken by LGMDP AFTER flashing to CM7)
P.S. Before posting I looked for similar posts, but could only find ones dealing with the New Baseband (e.g. http://forum.xda-developers.com/sho...&highlight=error+while+searching+for+networks). As I have the Old Baseband and CM7.2 requires the Old Baseband (so it seems), they seemed irrelevant.
Thanks in advance!
Cm needs new baseband. There's your problem.
As a substitute, chech the cm7.2 development thread in the original work category. The first post provides a temporarely fix.

Mine got strange problem:
After flashing ROM PowerGB X 1.0, everything works fine (sms receive & send, Internet via mobile / Wifi, calling outside) but only one problem, I cannot receive call! When I call from outside to my P500 no, the network always says busy or I've requested to block my phone from outside.
I've check all settings regarding call blocking, but all is normal.
Thanks, thatnextdoorboy!
I've updated to the new baseband (using the LGMDP guide) and it now works great!
I think that this guide is a bit unclear, reading it it seems that only CM7.2 Nightlies require the new, while the Stable version doesn't.
Thanks again! (You're actually pretty nice to newbies around here...)
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..

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.

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.
Hi there,
First post where I feel like I've tried everything and about to give up. Bought SCH-i705 Verizon tab 2 7.0 with LTE, I live in Canada in an LTE metropolis with TELUS service, I rooted the tablet according to here which was successful.
I never was able to edit/add APN's (there was nothing showing or options to do anything on APN setting page...so then made a few edits to build.prop with two lines where I can add/edit and return to default. (ro.sales_code=LOL and ro.csc.sales_code=LOL)
I've edited the apns-conf.xml file a ton of times, made adjustments all over the place comparing to my other android units and forums for TELUS apn settings. I disable the Non-Verizon Sim Card alert just so that I could feel better about maybe getting somewhere.
I'm a noob (and a girl) and this is the first root I've ever done JUST because I couldn't ever obtain LTE/3G data connection. WIFI is great but I bought this unit for the chance to be mobile with it.
Tonight I thought Mr. Hyde's Modem change here would kick it in the butt but still, reboots continually give me "No Internet Connection" errors. Is there a way to tweak in build.prop to get this functional? I really don't want to have to set up a hotspot for this puppy when on-the-go.
Thanks in advance,
Lisa
What i would do is do a clean flash of the rom again before trying various modems. MrHyde03 has two modems i believe that he has posted for the sch-i705 one is the g3 and one is j1. If youve downgraded to g3 i suggest flashing the newer j1 before you reflash his rom. after you have the current up-to-date modem flashed then boot into recovery and do a factory wipe. also make sure to go into mounts and flash the /system. Try to flash the rom again after youve done this before attempting to mod the system since there are no other post for internet connection errors in hyde's thread.
I ran thru doing a clean flash of the rom and steps you outlined. Still no avail... One thing I noticed this time on the locked screen was "searching for service"... when I went on to attempt to add my APN with the 2 lines from my frist post into build.prop so I could add my APN settings, the "searching for service" went away.

<bump> hadn't heard if anyone else had any other ideas to get data working. I don't have a way to test whether a data connection functionality is even possible as outside of Verizon territory at this point. Any other Canadians in Bell/Telus/Rogers regions playing around with this specific device?
