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!
I recently rooted and started applying roms to my nexus s. Everything was going fine until my network data stopped working.
Have tried to unroot and return to stock but cant seem to get it right. whenever I try to use clockwork recovery any update zip i apply fails. Im currently on:
version - 2.3.1
baseband - 19020AUCKF1
kernal - 2.6.35.7-g7f1638a [email protected](hash sybol that isent on my mac keyboard)1
build - GRH7
I am based in the UK and think nthat my radio could be wrong?
When I factory reset in 2.3.1 i get the official update to 4.4 which dowloads, verifies then on installation stops and wont complete.
I am confussed with all the terminoligy and find the info on here overwelming to follow correctly.
on another forum i got the response that if i dont understand the process then I shouldent be doing this. Fact is I thought I did know what I was doing until it went wrong.
Could somebody be good enough to help me through this so I can restore my nexus s to working order please?
Read this thread: http://forum.xda-developers.com/showthread.php?t=1116884
Check your phone model, behind the battery. You probably have a gt-i9020 since you are in the UK.
Probably you need to flash the correct radio. What's a good choice? If you do have 9020, anything in the list with kb3 in it.
Kb3 has no limit to how fast it can upload data, which can be a benefit depending on how you use your phone. Most people would choose kl1 which is the most recent.
Download and flash in cwm recovery. Reboot.
Let me know if that works for you.

can you make calls? if you can, check your apn settings, settings>Data and networks>More>APN and delete everything, and retype the correct values for your carrier. if calls doesn't work, follow the post above. ^
I upgraded 2.3.5 but HATED it, so I decided to flash back 2.2.1. The problem now is that I get no service at all. I tried dialing *228, but it said I needed to turn off airplane mode to make a call (airplane mode was not on). Can anyone help me get my service back? If any extra info is needed, please let me know.

Well, I've been searching around and it seems as if I need the radio file for EE19. So far, every download link I've found is 404. Does anyone have that file?
EDIT: I had bricked my phone, but I figured out how to un-brick it. Still need that radio file and the method for installing it if anyone has it.
Nevermind, I got it working. I don't know for sure what did it, as I did pretty much the same thing over and over every time I bricked it, but one time I just happened to get service.
Here's what I did to get service:
1. Bricked my phone accidentally
2. Flashed DI14 using ODIN v1.83 (Make sure you select it from the PDA button)
3. Restarted phone, made sure it worked.
4. Turned off phone and flashed EE19 using ODIN (again, make sure you select it from the PDA button)
5. Turned phone on, and it had network access for no reason.
I had done this exact same thing a few times before, but I didn't have network access until the last time. I don't know why it worked, I just know it did. If anyone else is having the same problem, I hope this works for you, but no promises.
Also, if you do end up bricking your phone, the best way to get it to work again is to use ODIN to flash DI14, turn on the phone, then remove battery and flash EE19. Then you can upgrade from there.

picked up a used m8. Which had cm11 pre installed (fine with me it's what I'm used to running on my old galaxy nexus) just picked up a new sim card today and put the new sim in and it should be active but it wont pick up any vzw service (no bars just the empty triangle like shape) Any thoughts on how to get it to pick up signal?
When I hold vol down and power on I can see the following
CID - VZW__001
HBOOT - 3.16.0.0000
RADIO - .89.20.0321
OS 1.55.605.2
Appears to have the new radios and software.....
Normally, I would just restore the backup but there was no back up on the phone.
My first thought is to try flashing the most recent radios to see if that's it, but can this be done through .zip file in cwm or twrp? Or must they be flashed via fastboot?
Second thought is to reflash the stock 4.4.2 ruu then do factory reset.
Third thought....Is there anything else that I can do?
I wanted to get input from those who are more knowledgeable than myself on what would be the best method for proceeding..
Thanks

The info you posted isn't the new radios or the new firmware. Try flashing the 4.4.3 firmware from my firmware thread..update that an see what happens. You can find my firmware thread in Vzw m8 development.
OK I'll give that a try and report back
Ok I followed the directions and now I get signal in the triangle and an LTE connection. (Thank you Tigerstown much appreciated)
Now, When I hold vol down and power on I can see the following
CID - VZW__001
HBOOT - 3.18.0.0000
RADIO - 1.09.20.0702
OS - 2.21.605.2
but when I go to place a call it says "Mobile network not available"
After CM boots When I go into Settings > then about phone> then status everything looks normal shows verizon wireless under network but a few lines below under Service State is says "voice: Out of service, data: in service"???
Any ideas on what else I should do to get it to be able to make phone calls? Should I try flashing the radios via fastboot? Since I just used the sdcard method mentioned in your post instead of the fastboot method to update?
and strangely enough also under status a few lines below that it shows Mobile network state of connected.
feel like I'm close, just missing something.....Anyone more knowledgeable than myself have any ideas to get it to be able to make calls?
Thanks

So I downloaded VZW stock pre-rooted rom and as soon as I booted up everything started working as it should. Didn't even get to removing sd or re-flash stock recovery or factory reset. I might do that eventually as I do want to go back to CM or maybe viper rom. But I def. wanted to report back and say thank you for your help! I really appreciated it!

Hey fellow XDA'ers, I have a strange problem on my G920T that's been bugging me for a while. After flashing a custom ROM, my EFS was messed up. Thankfully I had backed it up prior to any custom ROMs. All works well n the phone except whenever it's rebooted it fails to register to T-Mobile's network. So I have to bring up the dialer, type in *#2263# and choose Band Selection, then LTE, then LTE All (which is already asterisked) and tap it again. Only then will it register on the network and then works fine. I've tried everything under the sun including restoring EFS backup, flashing back to stock, etc., to no avail.
I'm wondering if anyone knows of or can write a script that automatically runs the above process after reboot. I don't know enough to do so, and I'm not sure one exists. Not a vital request, more of an "I'm not going to be beaten by my phone" kind of thing. I'm willing to throw a $$ donation if someone were to write or provide a working script. Thanks!

Before you do that, is the custom ROM based on the same baseband your phone has?
Yes, the custom ROM is based on the same baseband - which is a great question. I’m using the stock rooted deodexed deKnoxed DOJ7 T-Mobile variant ROM with DOJ7 baseband. I’m DOJ7 across the board. This problem has persisted through multiple stock and custom ROMs. It seems to have started when I flashed the Back to N0t3 Note5 port to S6 ROM. I also get the Security Error: Your device has been flashed blah blah blah - but only when manually registering on the network.
I’ve been around the block as far as rooting and customizing my phone for a good while, and I’ve tried every trick I know to get this straightened out. SIM card works fine on my wife’s identical S6, so it’s not that. Short of hardware failure (which isn’t likely based on functionality when manually registered on network), something in some file was erased or corrupted and I can’t figure it out. Thanks for your question.
