Hey Everyone,
Recently had a go at flashing different roms on my Nexus S and all went well apart from not being able to use 3G which was really annoying as I use it all the time when I am out. I flashed numerous roms and could not get any access to 3G just Edge network.
Then did my final flash and totally lost all access to my network... I solved this by flashing to Android 2.3.4 then doing an OTA update to Android 2.3.6 and all was ok.
Now that I have a working phone again I would like to know if I can possible upgrade to Ice Cream Sandwich without any problems such as losing my 3G access?
Do I have to back up any folders like the 'efs' folder then copy it back when I have flashed ICS? Or is there more folders that need backing up and copying back after flashing ICS that contain important files to run my Nexus S properly?
I would appreciate any help you guys can give me.
Current working phone details are as follows:
Network: O2-UK
Model: Nexus S
Android Version: 2.3.6
Baseband Version: I9020XXKF1
Kernel Version: 2.6.35.7-gf5f63ef [email protected] #1
Build Number: GRK39F
Preferred Network Type: GSM/CDMA auto (PRL)
If you need any more information to help me just let me know.
Looking forward to your help.
Thanks, Lee
It is weird that you cant use 3G. That's not supposed to happen. You should try to update your radio, that might help.
you don't need to backup or restore any special folder. just make a backup of the efs folder to make sure you dont lose your personal information.
Im running CM 9 v.3.4 and i dont have any big issue. Just some random reboots once in a while.
Thanks for your reply quiquegabriel.
Yeah I don't know what went on with my 3G, I used to get it everywhere and I never would see Edge on my phone. Then were I would get 3G like at work for example... it would be Edge after a flash. I found no solution for this unfortunately.
Because I had so much trouble with the flashes before its made me reluctant to do it again. Which is rubbish as the most of the roms I flashed were amazing like ICS.
I have heard that there is going to be an ICS update for the Nexus S this month but how true this is anyones guess.
Thanks again for your reply.
Cheers, Lee
Did you check your APN settings once you flashed ICS? Usually these settings are automagically populated with ICS but who knows if any of these did not match. You can compare your settings with what you have in GB and configure once you have ICS.

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...
I was going to return my phone when i found this thread about radio

Now i think iam going to try other radio (ope i wont kill my phone....lol)
Thanks again.....

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.
ok here goes, first off, i apologize if this is in any way redundant to someone's else question. with the amount of people whose phone got wrecked with the 2.3.6 update im sure somebody has had the problem im having.
like many people i just clicked "install" when google pushed the 2.3.6 ota. my phone was running 2.3.4. rooted. when it rebooted, i was greeted with the android exclamation mark.
i happened to have a clockwork backup so i tried restoring my backup. and restore it did, but not the radio. after the google update my radio was something like NO GSXXK1 or so. i tried the radio fix here:
http://forum.xda-developers.com/showthread.php?p=14564429&mode=linear#post14564429
i tried reflashing the stock 2.3.3 rom from google, wiping the bootloader and all. ive in fact tried many many things that ive read on xda and google forums.
now, ive managed somehow to have a running 2.3.4 with cell signal. using the efs file copy method in he link above. that restored my 3g and ability to place phone calls but sms arent working. i did the *#*#4636#*#* thing and notice that smsc is 00, i tried to set to the right value of +17057969300 for Rogers canada but all i get is an update error followed by a crash.
and now, funny, my search button is acting weird, like an eye that keeps twitching.
im not very knowledgeable in this stuff, just enough to get by and install custom roms but clearly im in over my head now.
why did copying my 3 efs file in the root of the sd card restore signal? i dont think these files really belong there, so just what the heck happened?
is there a way i can restore my nexus S to google stock rom when they shipped the phone? i mean, a complete wipe, sd, boot, radio...everything.
if i can start back with the stock phone, i can re-root again and start fresh.
any ideas please??
im physically tired of reading everything, misleading information and constantly flashing back and forth hoping its gonna work. oh and mandatory angry comment: thank you google for effing up my phone!
edit:
the only stock rom i tried i the 2.3.3 stock update available in clockwork. made no results.
current specs:
my phone is a i9020a
current baseband : NO DGSXXKD1
current build: GRJ22

Thanks dude, i had actually done that and did manage to get a signal back. its SMS that just wont work and when do the INFO thing to set the right value, i either get update error or a crash.
i installed stock rom 2.3.4 and install radio uckd1. that made my signal work even without having to move the efs files on the root of the sdcard. but still no sms.
is anybody else getting sms problems? this was working before the 2.3.6 fiasco.
im with rogers canada, in ottawa.
ok, just to loop the loop on this one and hoping it will be of use to somebody else.
my sms issue wasnt related to my phone at all, once i had a signal back, that's as far as the phone was concerned.
i placed a call to rogers to let them know i couldnt sms anymore.
long story short, they tried many things but ultimately, its doing the "hard" reset on the network for my phone that did it. im sure there a better name for it but basically they erased my phone from their network, i had to wait about an hour for the change to propagate. when i powered the phone back, it resynced everything and sms was back online without a single thing to do.
Dear friends,
I am still new at this. A few weeks ago someone who told me they know how to flash roms would install a ics rom on my Nexus S (I9020A) for AT&T. However since then I have been having extremely bad reception issues. Now my phone might show full bars and signal, however sometimes when my friends call me I don't receive them, also vice-versa. Also my texts won't go through for a long time and sometimes fail, and lastly my 3g internet won't work at all or would be really slow until it connects.
I flashed my phone back to stock (I think.) and I also got a brand new sim card but the problem persists.
If anyone could please help me in describing what might be wrong and what should be done to correct this, please help me out.
Find out what radio you have ( about phone) and try a different one.
Make sure you only flash the radio for your device.
ICS wasn't released for your I9020A officially ... I would not let a friend touch my phone like this lol...
Now..As suggested , settings/about phone : see what version of stock rom and radio are you using now .. and report back
Some people have a debate on what radio is good with at&t and what not ....
Did you do a good clean up before flashing GB back to your phone ? i.e. format system / format boot , factory reset and so on ?
Android Version:
2.3.6
Baseband Version
109020AUCKF1
Build Number
GRK39F
I did do a good clean up prior to flashing back to GB. Would you guys be able to recommend a good radio for me please? Perhaps a link to the thread with the radio. I live in Southern California.

Radio UCKF1 (New Version) perhaps you should try this

I suggest you also try old basebands like KD and KB.
Different baseband versions work differently in different regions and reception areas.
Hi everyone,
I have just started playing with ROMS etc. and its turned my sluggish old-looking p500 into something beautiful,
The only issue is I just can't seem to get the network to work. Wifi is fine, but no service with the SIM card I put in there. I don't even get asked to put a SIM code or anything.
I have spent the last few hours desperately trying to get baseband v20 on my phone since LGMDP was not recognizing my phone, and I finally got it to work, expecting miraculous results, but alas! nothing! Anyone have any idea what I can do?
Specifically I have installed this rom: [DEV][ROM][4.4.2][CM11] KITKAT for LG-P500 [WIP][VER-12 OTA]
but have not updated through OTA yet.
And i flashed v20g using a stock version (one which didn't come with my phone). I guess I will try flashing a stock which depends on the new bb and see if that works...
Also, I don't know if this matters, but I got the phone in canada a few years ago and am now putting a UK SIM in there.
Thank you so much for any help you can give!!!! I really want to get this to work!
-A
extra words:
Also, I deleted a bunch of stuff on my SD and know very little about how SIMs work, so if I have the "wrong kind" of SIM or if I deleted something (I have it all backed up) that I need to put back on the SD card to make this work, please let me know!
Thanks!

If baseband is correct, then check your APN ( Access Point Names ). Settings->Mobile Networks->Access Point Names.

With my old SIM, I can see the APNs from back in Canada, but when I put the new UK SIM in (which shows APNs on my wife's samsung phone) I see nothing listed for the APN.
Should I create a new APN with the same settings as from my wife's phone? Or do I have to do something else?
Does it matter wether the bb is v20c or v20g? As long as its for the optimus one I mean?
Could this have to do with my phone being locked? I'm not sure if it is locked or not... I was trying to unlock it using the code:
2945#*900#
Thanks so much for responding, I had all but given up!
but nothing happens when I put that in. Do I have to revert to stock rom for that to work?
Update:
I tried to put in the right APN info, but I couldn't save it for some reason. Doing some reasearch, I found that this might be a "Funny SIM" problem, but only see patches to fix this under CM9, and I am running CM11. Any ideas?
Cheers!

Patch may work. Old baseband patch worked thru JellyBean ( CM10 ).
What you're referring to, v20c, IS NOT baseband but software version. What version of Android was the device running when purchased? Anything under 2.3 is old baseband while 2.3 and newer is new baseband. There are two baseband patches floating around XDA. One for new and one for old. Old baseband patch can be found in my FAQ for the LG Optimus One. Post #8 I believe. FAQ

I thought I had upgraded to 2.3, but since it wasn't working I flashed the new bb using this guide :
http://forum.xda-developers.com/showthread.php?t=1149530
and made sure that it had definitely flashed. My rom says it is baseband version V20g under the about phone section. So unless this ROM is supposed to be running the old bb (which it didn't seem like that was the case) the baseband version should be correct...
Also, I had previously tried the old bb patch which you are talking about; that didn't work either. What I understood was that "Funny SIM" is a different issue, but maybe I'm just reading the threads wrong.
Thanks again for your continued help!
Solved!
Okay, so it was because my phone was unlocked. I had to:
- Flash the stock ROM
- Flash the OLD BB
Then I was able to put in the code to get to the unlock screen. Once the phone was unlocked,
-Flash new BB
-Flash new ROM
And it works! Hooray! I'm not sure how to mark the thread as solved though?
