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 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?
Hello all, I am new to this site and have a situation I could use some help with.
Last year I bought a new ATT SGH-I747 S3 in the US. I had it unlocked by T-Mobile and now use it in Ecuador.
Here are the facts;
ATT SGH-I747
Android Ver. 4.4.2
Base Band I747UCUFNE4
Kernel 3.4.0-1514807
[email protected] #1
This is the problem, I recently bought a Samsung Tab 4 to use for work. I intended to use the wifi-tethering between my S3 and Tab4. When I try to select hotspot I get a message saying "no data plan and or bad sim". Everything else works fine.
I went to my provider and they said the phone was broken!!? I went to a tech and he said that my provider is NOT in fact a 4G network as advertised and I would need a root to make it work. I have tried several apps to solve this but no luck.
I read that the CM11 Rom would correct this issue even in a NON rooted device, this led to several others issues; can't use Rom Manager on this device, can't make backup without root, I did finally find an app that would allow me to save my efs file but from there I have no idea what to do. If push came to shove I would lean towards rooting and using CM11, if it would solve the hotspot issue.
I have read several one click root, one click this, that posts but they seem to leave out some important pre root steps, like backup, efs file saving etc. At this point I am at data overload and could use someone who can give me the straight no B.S. this is what you need to do steps to resolve this. I am very good with electronics, but phones are not my forte.
Any assistance will be greatly appreciated.
Thanks,
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.

Hi
Did you ever manage to get it fixed I'm having the same problem on my g920f and my imei is 350000000006 and serial all zeros
Thanks
Mav
I have the international Note 5, with a t-mobile sim card. When I am on the 4g network and I try to call somebody it takes 20-30 seconds to call. When people call me, they can't reach me. Though the 4g internet works like a charm.
The only way for calling to work is to switch it to 2g, but I am loosing the 4g internet speeds.
I contacted t-mobile, they tried to reset the network, but the problem persists.
Any suggestions?
Would flashing with a custom rom help?
Should I flash the original t-mobile rom?
unce unce unce
I found the problem
The problem has to do with the volte... This option is not available with the n905c model that I have, and there seems not to be a fix with t-mobile. Fricken Samsung didn't put available this feature in the upgrades of some international phones eg the Dubai model that I have...
I have the same problem
I just bought two t-mobile branded Note 5's and I'm using them on Family Mobile (previously owned by tmobile). If I limit my networks to 2G & 3G all of my calling works fine but the moment I enable LTE all of my incoming calls go strait to vm. The problem persists on both phones so I don't think it's a hardware issue. I've tried rooted and unrooted, magisk and supersu. VoLTE is turned off on both phones (since it's not supported by family mobile) but I've tried every combination of settings I can think of and nothing helps. I hate having to choose between having LTE or getting incoming calls and would love to fix the problem. Or is there a good way to totally disable or remove the VoLTE services? If I remember correctly there were similar problems with some of the S4s that required an app like advanced signal status (??? been a while) to overcome. Can anyone help? Please and thank you.
I have the same problem
Hi all,
I have the same problem, even I have install & root with custom rom the problem still exist.
someone told me that the problem is in 3G signal.
so I decide to choose LTE & GSM only, & it works for me. however it could not give 3G signal on my phone.
Did you find the other olution of this?
Evening all, I've been having this same issue, hoping there would be a fix. Not ready to purchase a new phone when there is nothing wrong with the one I have still good for at least another yr(maybe). but not rite now.
i fix the problem
Hi all,
maybe this method could solve the issue. please try it & follow below step.
1. reset to factory setting then after finish please clear Dalvik Cache.
2. Flash with the latest Odin & latest firmware, but you don't need to change everything in options tab. then click start.
3. After finish, then insert APN as mention in this link (please read how to set APN on Galaxy note5)
4. After select your desired APN, please change APN name become ****4g.com (or you can find this apn setting in your carrier SIM (check in google)
5. Finish, please check your phone.
hope above method could solve the issue, however it works for me now.
please try at your own risk & don't forget to always save your data before.
This is the FIX for the Note 5 SM-N920 C, i know this works because i have been dealing with this for MONTHS, so i tried EVERY Custom Roms Untill i figuard WHY NOT flash a Stockish T-Mobile Rom with a Custom Kernel for the 920C. And Just like that i got My Awesome Note 5 BIZACKKK, Here we go, Follow these steps, Upgrade to the FIRST 7.0 that came out for the SM-N920C, of course you should already know to turn on debuging + OEM, Flash TWRP through Odin, then go to the TMOBILE Development Section and THANK "@Marinella" First and foremost for cooking up this Rom, Download his Stockish Unrooted Rom ++7.0 ROM Stock Unrooted N920TUVU4EQE1++you will also need (MAKE SURE TO THANK--->>> ""@AndroidSword"" ) this 7.0 Kernel, go to the seack bar and type it in, FUEL-KERNEL-V2 .... now before anything, Of course do FULL WIPES Of Everything like you usually wipe when downloading other Roms, flash the stockish Rom first, then the Kernel, Just so you know, the Kernel has 2 choices of root. ITS AS SIMPLE AS THAT>>!!!!, Boot your Device and wait, this took me months to figure out after flashing so many diffrent Rom, Now I Have My Favorite International Note 5 Back, trust me , this WILL WORK ON THE 920C. ENJOY...
hi,
above method is for SM-N920C, do you have solution for SM-N920T ?
No Idea, sorry, try different Custom Rom, i have not heard of this issue with the 920T. Good Luck.
