I just got a new Nexus S purchased from a Rogers store here in Canada.
I am eager to start flashing some new ROM's and such but I have learned some things in the past with my SGS and I really want to make sure I have my stock radio available in case I need to flash it back.
i9020AUCKB2 is my stock modem. I have some newer modems ready to flash but I am worried that it will cripple my 3G connection to Canadian carriers.
I have looked and can't find this modem anywhere. Also I don't know how to back it up myself. I have already done a CWM backup but I have read that this doesn't backup the radio firmware.
Does anyone know how I can easily backup my own radio or where I can download it from?
+1 I've been searching for the last few days info about the exact same thing. I just sold my i9000m and was hoping to flash some new roms with this phone too but not gonna try until I either have a stock odin version of this rom or at the very least the CKB2 modem.
+1 same boat, want to know this too
Just bought Nexus S yesterday Telus baseband I9020AUCKB2.
Rooted and installed CWM 3.0.2.4 and flashed CM7 (Great ROM) baseband remained the same
from what I've been reading in Nexus S dev, Odin is something we should try to avoid if possible. I came from Fascinate T959D and I thought about it but that's probably one of the easiest ways to brick if you don't know EXACTLY what you're flashing and WHAT you're flashing it on.
Odin = last resort
lucidcoin20 glad to hear that flashing CM7 didn't change the baseband, I didn't have the courage to try it. I wouldn't flash just anything with odin but if you can find the right files it will get you out of a mess pretty quick. I agree its not for noobies with no clue what's going on but if Samfirmware comes out with the 9020a rom I'll make sure to have it on my pc for an emergency.
But from my phone wich is a Koodo version (went with them cause they were so cheap outright so I could go just cancel and go back to bell) we all have the At&t version so all Canada is the same. Hope it all works that way so I can go on CM7.
But would still like to learn how to backup the radio file in case I ever need it in the future.
Well I went ahead and flashed KB3. My speeds are less than impressive but I still have 3g with Rogers. Still looking for KB2 though to do some more testing.
Have you tryied KB1 radio, works good for me, i believe it is a US radio.

Flashed KB1 and KB3 and tested using speedtest.com app, three separate times over wifi and cellular network - the KB1 was roughly 10-15% slower than the KB3 for me..
KB3 labelled my radio as "ATT" btw

LMAO did the same thing but for rogers saved $75.
If you look in Q & A forum, there is a post for a clockwork flash, K2B radio, just posted in that forum today. I have flashed the radio, work great fore me.
You can get the KB2 radio file on my thread in the General forum at http://forum.xda-developers.com/showthread.php?p=13077026
Thanks a lot, I was unaware that the Canadian carriers used KB2. Currently I am using KB3 and I noticed that sometimes the call breaks up, however I am not sure if its the firmware to blame. Does anyone have similar experiences with KB3?
I have tested KB2 and KB3 and my tests are not constant. Sometimes I get only 1MB or less down and up, sometimes I get 5MB down and 3up.
I'm not sure why the tests are so different. I can do the tests one after another in the same place and get completely different results.
I am with Rogers and I am using the Speedtest app. I noticed at one point the speedtest app was connecting to a server in Quebec which made no sense since I am near Toronto. The test results I mentioned above do not take the Quebec tests into consideration.

I am sending my phone back into samsung for repair, and I want to bring it back to its stock condition. I have unlocked the bootloader, flashed CW recovery, and installed superuser with no problems, however cannot seem to figure how to go into reverse. I understand how to re-lock the bootloader. I have read on the forums through the countless amounts of people asking this. I am however trying to use the ROM for the GTJ61 build found from this thread http://forum.xda-developers.com/showthread.php?p=13478981 When I try to use Clockwork Recovery, and go to restore, it states there is a MD5 mismatch. Am I suppose to install from zip or update from SD with CWR, or should I try to flash everything back onto there? I do not know what to do. Am I even trying to use the right ROM? The GTJ61 build is the original build that came on my phone, but would another one work?
follow this thread http://forum.xda-developers.com/showthread.php?t=1033269
all you have to do is clear your data, flash the stock rom and stock recovery, and then lock the bootloader
Thank you very much. I figured it out. All I have to do now is destroy the evidence on my sd and seen my NS away.
I realize superuser is still alive and well after I did everything. How I would I get rid of it?
I just uninstalled it. it might have gotten restored when you logged in with your gmail account. did you wipe data and the cache with cwm before you flashed the rom?
edit: did the ots update to 2.3.4 install fine for you?
I am guessing you mean ota. I ended up using the 2.3.4 rom. Should I have used the 2.3.3? Yes I did clear out the cache and factory reset.

I did mean ota lol. my bad. where'd you get a 2.3.4 rom from?
edit: if you used the 2.3.4 rom from the thread you posted, just be aware that it isn't official. i'm not sure if the link I posted has the official rom, but you can download OTA updates with it so I would assume that it's pretty damn official lol
I don't know too much on the subject, but I'm afraid that since it is a different build in the link you suggested that I will mess up my radio settings. I don't know if it would make a difference but when I did install superuser it was from CWR and not adb from the command prompt. Do think I should use the 2.3.3 rom you suggested?

I don't know much about it either, but I would assume that you should put it on a stock rom if you're sending it back into samsung. I could be totally wrong though
I just am not sure if having super using on there would make a difference. They are suppose to do a wipe anyway. But I will contact them to make sure. It would still be nice to have superuser gone though.

I would guess that superuser would be one of the first things they check for to see if you broke warranty. you could just uninstall it and wipe everything through cwm again to make sure it's gone
I managed to fix everything. I just was searching through the system folder of the 2.3.4 rom and to my surprise there was little old superuser. So I deleted the .apk and bin files. After that I restored the ROM. Fixed everything. The stress of sending in a phone with superuser is gone and I am back to being stocked
Two questions for you OP:
1. How do you have a warranty on a I9020A? Is it the subsidized version from Best Buy (i.e. "AT&T's sanctioned model")
2. Why do you need warranty repair? What broke?
Yes I got my phone from best buy. I just registered the imei with samsung and I am under the 1 year warranty. I have a problem with my battery draining 80% in 6 hours little to no use with all radios besides 2g turned off. I know that the NS has not so stellar battery life, but there is genuinely a problem with mine. It cannot even survive for half a day.
Hmm, I had that very issue with three past i9020a's (two from Amazon, one white one from Newegg). They were all the Rogers model, which is said to be identical to the one Best Buy is selling as a subsidized model.
I just bought another i9020a on eBay (no, I never learn) and hope to try some fancy methods to save on battery life (ROMs, etc). I also experienced VERY slow 3G with the i9020a on AT&T's 3G network here in the US. Like 300kbs download slow. I read that if you flash the radio to KB3 it gets very fast, like HSPA 3G should be.
I don't care about rooting and flashing because my phone will not have a warranty. I do, however, suspect that there is nothing wrong with your phone, rather the battery life is just random. One of the i9020a models I had drained a fresh charge in like 3 hrs of sitting idle w/full bars. The phone was burning hot. I restarted it, charged it up, and it lasted over 16 hrs the next time. Very erratic and strange, but that seems to be par for the course with the NS.
I would first see if the phones you bought were registered yet. You never know when you would need samsung to take care of something for you. The correct radio for the US ATT is UCKE1. You should be getting data speeds of about 3.3 megabits. My battery has been consistently low.

So that may explain what's different between the international (i.e. Canadian) I9020A and the "Best Buy" AT&T sanctioned I9020A...a different radio?
Is it possible to flash the KB1 radio of the Canadian I9020A to the AT&T friendly UCKE1 radio?
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.
Well, here goes.
I've been reading alot for quite a while, and learning everything I could around this place. Thanks to tall who contribute.
I'm running NScollab, 1.0.42, with matrix 8.0 kernel.
Currently on the XXKB3 baseband.
Following this thread http://forum.xda-developers.com/showthread.php?t=1116884
I tried flashing the new KF1 radio for the nexus S. No luck. Either is doesn't flash at all ( status 6 error ) or when it does ( the signed version can be flashed in CWM ) no signal whatsoever. I've tried everything, changing the band, ( *#*#4636#*#* ) rebooting 45 times, dalvik wipe, changing type of radio, all guides, searched google, this website ( for a whole week ).
Nothing came up.
I'm posting, because this is pretty much last resort. I actually tried the KF1 radio on Miui, devnull, oxygen, and NScollab.
Telus users out there, what is your baseband ? What radio gives you the best signal and performance ? I know koodo switched to KF1, but I can't get it to work on my NS.
Any help is appreciated !
still noone ?
Darn.

I use KB3 for koodo(telus). I get signal... and it works.
I'm curious as to whether KF1 would be a better radio for us, or if it even works for Telus/Koodo. Anybody know?

I have a Telus Nexus S in BC and I just installed an OTA update to 2.3.6 / GRK39F / I9020AUCKF1 and the KF1 radio seems to be working fine. I've been able to call around and MMS without issues so far. (about 2 hrs) Not enough time spent with it to tell you if it gets better reception or not...
I acutally installed the OTA pacakage in order to go back to stock as I was getting sick of the Search Bug that has been plaguing my phone for ages and I was going to bring it back for warranty work, but it appears the flash of the radio to KF1 that was included in the package has resolved the Search Bug!
Sweet! So, I might stick with this for a bit to confirm it is gone and and if all is well, I guess there's no need to return the phone for service!
I have the same issue on koodo. Flashed ICS and I get reception with KF1 downtown but barely anything at home and it used to be great.
I'm running the UCKF1 radio on my telus NS, on cm9 + matrix 14.5. With my phone, it was impossible to flash the radio with CWM, it would flash, but could not get on the network. I had to use fastboot to flash the radio.
In my experience, XXKB3 and XXKD1 were definitely the fastest radios (no upload cap), but my connection was unstable, needing occasional reboots to reestablish connection if I ever lost reception. UCKF1 has been rock solid for me. (I'm in the Toronto area)
Also, for some reason I only started getting the search bug with ICS and XXKD1, but UCKF1 fixed that.

So my friend has a Nexus S that he bought from Rogers, using on Rogers etc. He put CM7 on it a while ago, didn't really like it so he tried to go back to stock as much as possible but is having some issues. I tried to help last night, but holy smokes there are alot of different radios and versions out there. It was so much easier when I had my nexus one compared to this (or so it seems to me). Anyways, for a Rogers user, what is the best (or most current) radio to use? He has tried the UCKD1 and B2 I believe, but had problems with not getting 3G. And even when he did get those on, and tried to install the OTA update, the update crapped out on him. I'm not 100% sure his phone is the I9020A version (it seems that way for ROgers though).
So I guess I will summarize some questions, that was a bad paragraph there.
1. What is the best (most current) radio to use for Rogers?
2. Can I combine the radio from Q1, with the current stock rom (2.3.6) and just flash with CWM recovery or fastboot?
3. Can someone verify the model number (I9020A)?
Thanks for the help!
search through the radio thread for Rogers to see what others ate using. You can determine your phone model by looking at the label under your battery.
Obscurely referenced from the fifth dimension on my Nexus S

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.

I suggest you also try old basebands like KD and KB.
Different baseband versions work differently in different regions and reception areas.
