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'm (obviously) a bit of a newb when it comes to android, and I was flashing back from cm7 to see how it was done. When I reinstalled GRJ22, everything was working fine. I then downloaded and flashed the OTA update to GRK39C (or so I thought). It turns out it was the update to GRK39F, which apparently is ATT or GPRS specific. My phone now thinks it's on ATT and is trying to use GPRS.
I'm on Telus in canada, and use HSPDA.
The phone was also showing baseband version I9020AXXKF1, it should be I9020AUCKD1.
I've tried restoring from a backup, flashing back to cm7 and to stock fw's, and even tried flashing the radio.
My phone still shows GPRS, and now baseband version shows I9020AXXKD1.
Is there any way to fix this? I hope someone here is knowledgeable about this...
That baseband is associated with the i9020t, or the t-mobile variant. The canadian nexus s is identical to the at&t version.
There is a sticky with all the roms. Use it and get the right rom installed
Unfortunately, the ROM I need seems to be one of the missing ones. Is there any way to backup the radio from my wife's (identical) phone and flash it to mine?
It looks like the file I need is 5282b5b3eb74.signed-sojua-ota-178324.5282b5b3.zip but I'm unable to locate a working link for the file. Can anyone tell me if this is correct and/or provide a live link?
Actually that particular one you want has broken tethering... This is a dump is the 2.3.4 with I9020AUCKD1 radio from my US import i9020a tested and working on SaskTel HSDPA+.
http://dl.dropbox.com/u/7812800/Stock-GRJ22-i9020A-unsigned.zip (will need to be flashed via CWM Recovery)
Thanks! I got it working by flashing the unsigned ROM in the sticky thread, and I'm running cyanogenmod 7.1 RC now. I'll keep the stock ROM on file just in case though...

Cool... I hope it works out well for you.
btw i got a rooted version of the stock 2.3.4 if you are interested as well.
So, for some reason flashing with your ROM set my phone to UMTS. Can someone refer me to a howto to backup a full ROM image from a phone, since my wife's is working fine and is on the right type of network.
Need some help for my device [T-Mobile] HTC ONE S (S4). I'm using in INDIA.
For the past 3 years i have used this phone in 3G network with out any issues. Last week i flashed a new ROM but after that i don't get 3G signal.
I tried a lot of ROM's and Radios but still it is not working. So i flashed the stock ROM and RADIO but still its not working. I understand the bands the T-Mobile uses differs but it was working fine before flashing a different ROM.
I don't know what to do.
So please if any one using the same do upload your ROM and RADIO and other things that influence the phone to work.
P.S: I posted in various threads and asking for help but i don't get any reply hence started a new thread so everyone like me can find it useful.
Thanks.
EDIT:
I flashed the Official T-Mobile JB RUU and my phone started to reboot after showing up the "preparing Phone Storage" (soft bricked)
Finally solved the issue:
I have flashed the official T-Mobile JB RUU after relocking the bootloader, S-ON, change CID- ********(Stock cid , In my case its T-MOB010).
Now i have a brand new phone working good.

thanks for the reply,
I tried it and still my radio gets error . voice quality gone to worst.
I tried to install a custom rom again without s-off and i succeded but my phone reboots occasionally and my radio disconnects from the network occasionally and do get it back i need to search for network.
Atleast all other things work good.
Im planning to try to flash my kernel with the official stock kernel downloaded from HTC .
Will post if that works.
Thanks again
Best voice quality is in stock rom!
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
Somehow I ****ed up and now my phone cannot receive cellular signal at all. In about phone, IEMI number is unknown and in SIM card info, everything is unknown. What I did was this.
1. Flash CSC Selector on my existing ROM selecting ATT CSC. Everything was fine (aside from no voice/wi-fi calling)
2. Wanted to update to latest stock PDA/radio/bootloader so I did (through Odin.) Everything still good.
THIS IS WHERE **** HIT THE FAN
3. Flashed TWRP.
4. Formated data, flashed CSC selector selecting ATT, flashed Makisk, flash Makisk-PHH rot.
After that, no cellular signal at all.
Can someone help please? I really need this phone for work and if I can't get it working tonight, I'm going to have to go to AT&T store and ask for the cheapest phone they got until I can get this fixed...
BTW I already tried re-flashing everything to stock through Odin and it did not help.
