[Q] Nexus S - Canadian

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.

[Q] Help trying to get friends Rogers Nexus S back to stock(ish)

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.

[Q] Nexus S major reception problems

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.

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!

[P920]what firmware to flash to not lose IMEI, networking, 3D camera and others?

I've started installing custom roms for P920 and opened a can of worms having ultimately to find the original firmware to fix my IMEI, signal, camera and others
What stock firmware can I flash on P920 that doesn't break my phone's functionality? I've flashed v20d because it said it's LG's latest recommendation for P920 by using search by IMEI here :https://lg-roms.com/?id=, but that didn't restore any of my functionality until I installed v10L, a french orange rom probably identical to my original one, so I don't know if now I install v20d again that it won't break my stuff again
Need help from someone who upgraded successfully to tell me what to properly flash. Thank you
P.S. Also, are v2, v3, v4 firmwares for LG better for it's battery life? I've installed a v4 custom rom that burned through my battery just idling...
EDIT: changed tactic for picking my target Android. My main criteria is longest battery life, beside getting a firmware that works for p920. I'm amazed how hard is to get a straight answer for minimum system requirements but I've found a credible answer here: https://www.intel.com/content/www/us/en/support/education/intel-education-software/000006179.html which tells me not to install v4 or higher on p920 ever - in fact I run a cyanogenmod rom and was very sluggish. Because v3 is one for tablets and brings nothing meaningful according to my criteria, that only leaves gingerbread (v2.3) and froyo (v2.2) to pick from
Also, this comparison helps: http://socialcompare.com/en/comparison/android-versions-comparison
Also a good read: https://arstechnica.com/gadgets/201...rbread-four-years-later-the-os-just-wont-die/
Then the question becomes since I'm already on v2.2, what v2.3 P920 original firmware I can flash w/o losing imei, networking, airplane mode etc.? I seem to believe from all I read that I simply lost that functionality because I've installed custom roms in between, and I can install any P920 original firmware but need confirmation
EDIT2: experiment:
battery test in idle airplane mode: 1 a.m. 100%
battery test in idle airplane mode: 9:30 a.m. 94%, that's 0,63% / hour. BootV21E from the unbricking tutorial lost 75% in ~12 hours, like 1000% more because airplane mode didn't work, and so did the other roms I tried. That's the difference between proper firmware and improper firmware
EDIT3: installed v20d because it seems the right firmware: https://lg-roms.com/official-firmware/LG Optimus 3D-LGP920/V20D/ROMANIA
seems everything is working. Testing battery again on airplane mode. I must say froyo looks better than gingerbread theme Must change...
LG specs are full of shat about battery on stanby (460 hours or ~20 days): http://www.gsmarena.com/lg_optimus_3d_p920-3759.php
EDIT4: v20d
battery test in idle airplane mode: 13:11 p.m. 95%
battery test in idle airplane mode: 20:43 p.m. 93%, that's 0,26%-0,4% / hour.
EDIT5: v20d
battery test in idle airplane mode: 20:43 p.m. 93%
battery test in idle airplane mode: 15:38 p.m. 88%, that's ~0,29% / hour, that's 344 hours in a 100%, which is 460/344 = ~33% battery degradation in 5 years (according to spec, didn't measure battery actually resisted 460 hours on idle)
consuming (idle mode)

I'ld say I've succesfully upgraded, thanks xda-developers!
my short tutorial after opening the updating rom can of worms, so I remember myself in case I need to:
1. (problem, or your can of worms) installing a custom rom even if it sais it's for your exact model is bound to cause problems, as I tried the most seemingly wortwhile ones and as they each were missing something or behaving bad
2. (solution, which I didn't figure until the end) is to go back to original firmware, in my case french orange something v10L for my p920, since the original was bought through orange obligatory 2 year monthly paid service. Point was however to update w/o losing functionality, and so far I haven't tried flashing a clean firmware. Will come back on that perhaps. I've picked up my firmware from this list: https://lg-roms.com/?load_page=search&q=p920&page=1
3. (solution) after realizing you need a baseband they say to have a signal on those custom roms, you'll flash a baseband zip or something else that will "brick" your phone like I did because it also overwritten the bootloader badly, not allowing to boot anymore for instance. This is the solution: https://forum.xda-developers.com/showthread.php?t=2246001 There are actually more threads about this but this is what worked for me and seems the most easy. Just be sure to try and try again because if something doesn't work you're doing something wrong
4. (solution) what nobody told me is that you're supposed to put the kdz file in the same directory as lg flashing tool 2014 (wich I don't know if it works because I used the one from the forums: https://forum.xda-developers.com/showthread.php?t=2797190 You can also use smartflash to flash bin and fls firmwares, which you pick from here too: https://forum.xda-developers.com/showthread.php?t=1734330 In this post is the only place I read about putting the kdz in the same dir. If you can't flash kdz for some reason you can make from it bin and fls files like this: https://forum.xda-developers.com/showthread.php?t=2245469 however they say it may cause problems
5. (solution) after finally flashing the original firmware to get your stuff back, you might end in a bootloop. This is what you follow to fix it: https://forum.xda-developers.com/showthread.php?t=2426426
6. (solution) after losing IMEI files I fixed this by going back to original firmware, however it had another IMEI number written in them, which I rewritten using tutty like in this tutorial: https://forum.xda-developers.com/showthread.php?t=1734330 If tutty doesn't start or gives errors on write, try spamming it to start or the write imei command, it's got personality like that but it eventually works (don't ask me why, haven't seen this in computer programs often). Perhaps my cable is old, who knows
My bottom line is: don't flash custom roms unless you know how to not lose your functionality or how to fix them, and not even developers don't seem to do it since all roms have one problem or another which isn't mentioned in the custom rom's description. If you do however, this is what you go through fixing your phone, more or less
