Last week i had same problem, i almost got crazy, but after all, the problem was in my provider.
Have you tried another sim card?
Sent from my Nexus S using XDA App

That is odd...
I am also with Rogers and I got my phone bricked when I first tried to root it because some guy posted a wack file which bricked almost everyone's phone..
Anyways to the point... I also got the same stock image from the link you posted but for the 2.3.4 update I got it from searching on google somewhere. (Think it was one of those "How to manually update Nexus S to 2.3.4" pages).
I just checked my phone info and it displays all the same info as yours... I am pretty sure I had 3G even before pushing the 2.3.4.... Try locking the boot loader and re unlock and give it another shot. If nothing works, just lock the boot loader after you install the 2.3.4 update and take it back to rogers and ask them to send it in for a fix.

hi guys... thanks for trying to help me...

[Q] Help. Flashed my Telus Nexus S with ATT firmware, now network type shows GPRS.

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.

[Q] Flashing to stock - phone force closes process com.android.phone, help

Please bare with me since this is the first time having to post for an issue since I usually find an answer on your forums
So here's the situation.
I bought the photon q 4g lte from ebay and it came with the unlocked bootloader.
Needless to say it was with the stock ics and i tried to find a jellybean update because it wasn't taking the ota and ended up going with cyanogen since i had no problems before. However those phones i had before were with sim cards not cdma.
I found out i couldn't update prl or profile manually without having to do something on the pc.
So after searching left and right i found i could use rsl lite (I used 6.1.5) and eventually found the "stock" file from this post
http://forum.xda-developers.com/showthread.php?t=2095536&highlight=rsd+lite
I did the stock jellybean, got it to go through the process and it booted up with no errors.
However, when it boots into the os it pops up a force close on omadmclient_sprint_dataservice and eventually also on the process com.android.phone.
I tried putting it in airplane mode to see if the service error would go away but it didn't work for the process part crashing.
I tried re-flashing, deleting cache in recovery, doing a data/factory reset in recovery and the one time i was able to do a data factory reset within the settings menu.
I could not find anyone that said they had a rom that worked with sprint and updating prl within the rom, if anyone knows of one let me know and i will flash it through rsd.
Otherwise does anyone have an idea of what could be happening because googling the omadmclient part did not pull up anything specific and pulling up the process issue for other phones has not helped me either.

Was this a hacked GSM phone, or are you using it as CDMA?
I've never heard of people having FC issues after flashing a FXZ from RSD. Which one did you flash? Android 4.1.2 - Sprint US - 9.8.2Q-122_XT897_FFW-5 (No simlock) ?
If you are on stock, you should be able to update the PRL within the ROM.

I was trying to use it with cdma network through sprint. and yeah that was the file i downloaded, had to remove the getvar to get it working but flashed with no errors after doing that.
As for updating the prl i can barely navigate through the phone, there is no home page loading and the process pop comes up often enough that its hard to go through the settings

Sounds like something went wrong mate. Are you already activated on Sprint? I don't know if that would matter, it might.
I would honestly redownload and redo the RSD process.

I originally tried to activate the phone through cyanogen and then when the rep said he couldnt do it because of the lack of prl to update within the rom we just setup the activation back on the old phone/ That phone is working on the network.
I re-downloaded the file just in case and re-flashed but same problem. The only thing i thought of was maybe updating the radio but since its a stock rom it should work out of the gate. whats also weird is i tried turning wifi on but it didnt work either.
Anychange you know of a rom that works with sprint. I dont care if its stock since i would probably root later again.

Which one are you flashing?
Try another perhaps...? I honestly have never heard of this. It sounds like the phone might be damaged, or the RSD process just did not flash correctly.
I guess I should ask, was the phone modified at all for the GSM SIM slot mod? I wonder if having a non-Sprint SIM in is messing with it... That is just a shot in the dark.

so far the only rom i tried was 10.1 cyanogen and the stock rom for jellybean. However for the stock rom it doesnt let me downgrade to ics with rsd 6.1.5 do you think if i downloaded an old version i could downgrade to a lower stock rom?
Also I honestly had not looked for the cdma roms since most of what i saw was troubleshooting related for this phone but i just saw this rom -AOKP 4.2.2 (Android Open Kang Project) (CDMA&GSM) that you created - http://forum.xda-developers.com/showthread.php?t=2293892
I re-rooted and installed that one and it looks great, just wondered how you got sprint to activate the phone or if you had done it before changing the rom? Also how would the prl and profile be updated.
Lastly the wifi wasn't turning on this time either, it did work initially when i got the phone so that has me stumped.

To downgrade to ICS, you need to remove some additional lines. See this post for more information on that.
However, you should be able to update the PRL on either stock ROM.
I think I said this before, but I will say it again. You need to do PRL updates, activate the phone, and get EVERYTHING working on stock BEFORE you flash ANY custom ROM. This is just standard practice - you don't want to put the cart before the horse! Get the phone working, then play with custom ROM's.

Updating my p509 from 2012/2013

I purchased an Optimus T (P509) in 2012 and had it unlocked to use on a trip I went to europe. I played around with it a lot and messed with custom roms and basebands, and then left it alone for about a year. I'm now downsizing my phone/tech collection in general and looking to update this to use as a daily driver.
Here's the info about my phone:
ClockworkMod recover v5.0.2.0
Baseband: LGP509AT-00-V10l-OPEN-COM-OCT-23-2010
CyanogenMod version: 10-20130108-UNOFFICIAL-p509
Build number: cm_p509-userdebug 4.1.2 JZO54k eng.arjen.20130108.030427 test-keys
My questions are:
What updates to baseband (if any) do I need to do? Would this mess up my unlock?
Do I need to flash a new recovery?
What ROM would be best for my needs as a daily driver? requirements are stable without crashes and everything works, followed by the newest android version.
Really the rom part I can experiment with later, I'm just not sure if I've hosed myself with the baseband 'fixes' that I recall messing with 2 years ago. I have a new sim card on the way that I will use with this.

1 - Actually upgrading baseband on that device would lock you out of some frequencies the radio ( not the FM radio ) uses to communicate with the carriers towers. I also have a Optimus T ( P509 ), tho no longer in service.
2 - Depends if you want KitKat ( 4.4 ). If you do then you'll need CWM 6.0.4.4 or newer. I am currently working on a utility for older CWM versions to be able to install KitKat but until then you'll need what I just mentioned. If not too interested in KitKat then you can leave your recovery as is. I use CWM 5.0.2.7 Touch by @vivekkalady. I've been using her recovery since she introduced it.
3 - You'll have to search and make that decision for yourself as we all have different needs and habits.

That's interesting what you said about the current baseband, I'm not sure if I changed it after I last used it. But I turned off airplane mode and popped in a T-mob sim and it wasn't able to connect to a network, similar results with H2O wireless card (at&t mvno). I'm not sure if my current version of android is messed up or the baseband.
I don't mind upgrading CWM, is there any downside to doing so? Is there a kitkat build out now that works? I may want to use KitKat as I hear it's meant to be more usable on smaller memory systems like the p509.
I don't mind finding one I like eventually, but looking for a recommendation to start off with that should work without too much difficulty.
Thanks for you help so far, I hope if can figure out this cell network problem :-/

Either your APN settings are wrong, which you can manually fix, or you did upgrade/downgrade/change baseband. The P509 is supposed to be an old baseband phone. The P500 and P509 are identical. Only difference is the P500 is a new baseband device. You can flash a P500 ROM. If you don't get any signal, then most likely your on old baseband. There is a patch for that, no biggie. If you do get signal then you're on new baseband and you should continue to use P500 ROMs. If you decide to flash a P509 ROM you won't have any service which will be a baseband issue. There is a new baseband patch around here somewhere too.
You can find a link to the old baseband patch in the LG Optimus One FAQ. Post #8 or #9, I think.

I wasn't certain what my starting point was since I'd done this so long ago (and I thought I applied the old BB fix at some point too...). Anyways, I took a drastic step and installed the stock rom V10s_00.kdz with the kdz installer from LG. It successfully flashed and I don't have a brick on my hands
The problem is now the phone doesn't recognize any sim cards, of which I've tried 3: tmobile micro, h2o micro, and a gophone minisim. The microsims were put in a cut out minisim as an adapter. The gophone is a normal minisim that is uncut, but it's not activated. I never got a locked or bad sim message, just that there is no sim card in place.
Under phone status it shows a signal strength (varies -65 to -75 and 25 asu)
Under APN settings it matches the T-mobile ones
And the baseband via secret menu is amss6038
I'm wondering if the sim module or gsm module are messed up? I kinda want to try out the emergency calling but would rather not get the police involved

I messed up my SIM contacts when I left an adapter in there and pulled it a little too hard out! I removed the compression plate on the back and it works again. I'll have to get a small piece of electronic safe foam to apply pressure to the back of the SIM to keep it in proper position. (http://forum.xda-developers.com/showthread.php?t=2598308)
I'm interested in the kitkat build here: http://forum.xda-developers.com/showthread.php?t=2589303
If I were to want to use that, do I need to flash the baseband fix on top of the other install instructions? Anything special in terms of timing it at a certain point in the install process?
Thanks for your help so far, I forgot how much fun messing with android was :laugh:

Well, we still aren't sure if your device is new or old baseband. With the recovery you already have, flash CM10.1, CM10.2, or CM10.3 ( All JellyBean ). Latest CM10.2 builds can be downloaded here. Easiest way to work around the baseband thing is to figure out which ROMs, P500 or P509, that will give you cell service. Flash a P509 ROM. If no service then you upgraded baseband so you'll need to use P500 ROMs. Flash a P500 ROM and if no service then you're on old baseband and you should use P509 ROMs. Only difference between P500 and P509 ROMs is the P500 ROMs are NEW baseband and the P509 ROMs are OLD baseband.
As of now the only KitKat ROMs being build are for the P500. If you find you are OLD baseband, flash the oldbb fix from the FAQ I mentioned a couple posts back. Oh, and you'll need the newest CWM 6.0.4.4 or newer recovery to flash KitKat.
Hope all this helps...

Well, I'm on the old baseband, the reason I know is I used KDZ to nuke it back to p509 stock! The more I read about kdz after I did it the more scared I got, but I lucked out and everything is fine now
The sim unlock is preserved, and I successfully rooted it with gingersnap. I don't have any sort of recover on it yet, it looks like CWM 6.0.4.4 does not work with older roms, just Kitkat based ones. So I'll do some more homework and figure out if I want to jump right into KK or try JB first.
Thanks for all your help, you gave me a quick jumpstart and brought back a lot of knowledge that was tucked away in the back corner of my brain!

[q] need help with no service and no mobile network available

I have no service and no cellular network problem on my N5, running dark rom 7.1.2 aosp, with franco kernel ( never had issues before ), newest radio and bootloader. This started happening when i got my new sim card from my provider and i got 4g signal in my area for the first time. I tried manually selecting radio by going in the hidden menu by entering *#*#4636#*#* and i got lte and full bars signal after selecting band 8 ( 1800 hz ) but only for a minute then it went back to empty triangle. Tried selecting 3g only in preffered network, tried manually selecting provider, tried toggling airplane mode on/off a bunch of times nothing works. Any suggestion would be highly appreciated, i love my N5 very much and i would hate to throw it in a drawer somewhere. Thanks in advance

Were you ever able to get this rectified? I have recently been having this problem as well. I have flashed back to ROMs I was previously using and flashed back to stock to no avail. My SIM card works in other devices as well. I really do not want to have to drop on a new phone, but I have tried every solution I have found online to no avail. I think it's fair to say that I am desperate right now.
edit: I found another thread on XDA that I'm looking into, I'll edit again if it works. I'm unsure how it took me so long to find that thread.
edit2: https://forum.xda-developers.com/go...getting-cdma-networks-to-nougat-roms-t3534679 is the thread that I found useful; I am now running Pure Nexus 7.1.2 with a full connection. Specifically, his second comment about installing 6.0.1 stock, backing up the efs, flashing the desired ROM, then restoring the efs is what ended up fixing it for me.

No luck with aosp by santosh m and pure nexus 7.1.2 , can't even get it to connect. I guess my last hope is caf based i will try lineageos caf. All i need is the efs backup from stock? If i can get it to work with 3g i will be satisfied because i did some digging and found out that my network provider which is Vip MK has no lte support for nexus 5 d820 ( my model ) only 3g, but i can't even connect with 3g selected. I guess because this one is for US frequencies it will not work whatever i try but i will give lineageos caf a chance.

I was able to get 3G only to work on my Nexus 5 by reflashing the EFS from 6.0.1; I'm trying right now to see if I can install PureNexus 6.0.1 then dirty flash to PureNexus 7.1.2 with any success. Also, I might just switch to T-Mobile, but I have to wait until later this week for that.

Hi,
LTE band 8 is not in 1800 MHz but first of all you can check your N5 model - US model is D820 and is not supported for LTE on 1800 MHz (band 3). For 1800 Mhz band you need D821 model.
Regards,

Were you ever able to get this rectified? I have recently been having this problem as well. I have flashed back to ROMs I was previously using and flashed back to stock to no avail. My SIM card works in other devices as well. I really do not want to have to drop on a new phone, but I have tried every solution I have found online to no avail. I think it's fair to say that I am desperate right now.
edit: I found another thread on XDA that I'm looking into, I'll edit again if it works. I'm unsure how it took me so long to find that thread.
edit2: https://forum.xda-developers.com/go...getting-cdma-networks-to-nougat-roms-t3534679 is the thread that I found useful; I am now running Pure Nexus 7.1.2 with a full connection. Specifically, his second comment about installing 6.0.1 stock, backing up the efs, flashing the desired ROM, then restoring the efs is what ended up fixing it for me.

To clarify that:
You had the problem with not recognizing the sim or having no service at all. And you solved this by flashing the sstock 6.0.1 backing up the efs, flashing to Pure Nexus 7.1.2 and restoring the efs immediatley after flashing the rom (+kernel+root+etc)?
This solves this mysterious no sim/no service bug, which many (?) N5 owners experience? If this is true, I'd be really happy

It didn't stick. After I lost it I was unable to get it back. I gave up and switched to T-Mobile, where it is no longer a problem. Apologies for not having more testing information. I was able to get solely 3G on multiple instances, but getting the elusive 4G was beyond me.

I've had this problem before in two nexus, one of them running latest stock and the other a customized ROM. I tried to flash a stock ROM image in both of them with no luck. I was pretty sure that the image I was flashing was the latest, so the radio & bootloader should be flashed to the latest versions. But it didn't worked.
Finally I found on a XDA thread where someone was posting only the latest bootloader & radio to flash. I did it with NRT (in Advanced Utilities) and it worked:

I can't remember or find the thread, so I post the images here:
- Bootloader-hammerhead-hhz20h.img
- Radio-hammerhead-m8974a-2.0.50.2.30.img
I think I had to flash them twice because the first time it wasn't right, but there were 4 months since then and still no failure

Thanks for your input. I'll check that when I have some time. This is really weird as it looks like a hardware problem but if you can fix it with this method it's clearly a software issue...
best regards
