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 , Jimmy here!
After flashing my GS4G , i can no longer connect to anything 3G or higher. Only edge speed for my data connectivity. I usually get 3G/4G but not anymore. Any way to fix?
can you be a bit more specific? what did you flash onto the phone? what modem are you using?
as a general rule, I would just reflash the entire rom after a factory reset/cache wipe. sounds like it didnt flash properly. also, try to change your modem.
You could also check to see if your data settings are set to GSM only or GSM/WCDMA.
That's in settings > wireless and network > mobile network > network mode.
I remember after flashing something this one time (can't remember what it was), my data settings were changed to GSM only.
i used the rom from
http://forum.xda-developers.com/showthread.php?t=1146145
And it is not gsm only. It's auto mode
Also , do you guys have a good recommendation for a flash rom ?

Well, that ROM is already a problem, lol. Get the newest KI3 GB. You can't miss it in the Development Section. It's as stable as KH2 and just may be faster!
KF1 and KF2 are practically inferior builds of GB now.
So I have been messing around with the new ICS build from AOSP.
Since I have the unlocked white i9020a I have to use the 4g zip.
It installs and runs fine the only problem is that I get no service.
I've tried flashing different radios on it such as KB3 and UCKB2.
But when I head to about phone on it and take a peak at the baseband it says unknown.
Ummm why do u have to use the 4g version? I have an i9020a and I use the normal nexus s rom.
On an i9020a? Weird.
I tried using the regular 3g one but as I start the install it stops and says there is an error.
I have a similar problem. Trying to resolve now.
Yah I've been tinkering around with it and I just tried to run the regular 3g install after wiping the cache and etc.
: /
If your problem was like mine, no matter what I would get 0 service whatsoever. No edge, no 3g, nada.
Well, turns out my /efs folder was wiped or corrupt. not sure which one, but I downloaded this program: and restored my efs folder. I believe CWM makes backups now, or at least most ROM devs do now, it's apart of the script.

Restore efs, and service is back to normal.

I'm getting exactly the same problem, 3G doesn't works, the phone doesn't detect any APN.
Did you solved it?
Saludos.
shtrihcode- If you are on stock unrooted phone, make factory reset, if it's still like that, take it to the service center(presumably you have waaranty), it may have something wrong in the hardware. You can also try a thread below
ryohnosuke- check out this thread http://forum.xda-developers.com/showthread.php?t=2055298 if not, reflash your current rom, ore choose some other.
Well, I fixed adding the APN of my carrier, only that. :silly:
Saludos.
Hi Guys, I know I am an idiot for not following all those guides properly and now I think I have bricked my device?
Well I am in Australia and I have this G920P model on android 5.1.1 (Unrooted). All was working fine, I bought it second hand from someone, I believe this is a U.S Sprint version, But I had my Telstra sim working in it with 4g data without issues.
So I decided to root it (without backing up- I know my mistake) and then flash XtreStoLite rom (again without doing any backup of original Rom). After that My device did not detect my sim card and there is nothing in the IMEI section of the phone.
I tried to flash official G920P rom via odin which installed successfully, and it shows signal on my phone, let me make calls but No Data. Seems like it is not registering my phone on the network properly.
So what have I done to my phone? Any chances to recover it somehow?

Have you the efs folder in your / partition? To check:
-Open any root explorer
-Go to / and check if efs folder exist
-If exists any file into it, tell me.

Thanks for a quick response, I Installed a root browser app and yes I can see EFS folder there and there are a bunch of folders and files in the EFS folder. e.g bluetooth, carrier, cpk, Factoryapp, imei, lost+found.... and so on
Appreciate your help in advance.
Have you checked your apn setting ? Make sure your carriers apn settings are restored.
Ok. I'll look into it. Thanks.

Ok, I have entered my network's pan settings manually and I get can get the data working but it only picks up 3g not 4g. I can make calls too.
But every time i restart the phone it keeps on checking the network status and picks up the signal after 3-4 minutes.
Also its stuck on the Hands Free activation screen and keeps on re-trying it.
Any help would be appreciated if I can get my device back to a normal one. Any other ROM's should i try?
One more question guys, Is there any non - sprint ROM for this device G920P? Because when I bought the device, I had no sprint stuff on it. No boot up splash screen or anything. I did not make note of which build version was it on but it definitely said G920P and it was on android 5.1.1.
Thanks
You may find and extra menu by typing ##scrtn#. I wouldnt reset to defaut as those general would be sprints settings. Try to find your carriers apn settings online.You should be able to cancel the hands free default activation. Are you still rooted?

Stock or custom? If i find it i'll give you a notice asap.
I am now on a stock rooted rom. Would prefer to have a rooted rom. I have tried installing renegade but it get stuck on finding network and stuck in a loop.
Imei number is now showing up. But i wonder what version this phone was on when it was unrooted ? As everything was working perfect and i had no traces of sprint either.
