atm i got XXLA2, got it via fota before i rooted my phone, thinking about to switch to UGLC1. Got o2 germany, anyone got experience with whis rom from europe?

using cm9 stock kernel, got no comparison for the batterylife, own the phone at least a week. :)
[Samsung Galaxy Nexus] Carlos_Manuel:
hey Guys can you tell me ROMs that have UGLC1 baseband + the boot laoder for UGLC1?

Please, I still haven't figured out the battery problem, tomorrow I call to Samsung to get know what is the stock ROM and baseband that GN GSM is using in Finland!

It should be UGLC1 but I can't find good ROM with that baseband!

(no AOKP ROM or heavily themed ROMs)

:)

Thanks!
[Samsung Galaxy Nexus] maniac2403:
I would recommend stock Google IMM76I, since you don't want heavily themes ROM's. After flashing the ROM, install any radio you want. Only stock rom changes your radio, other AOSP rom's do nothing to your base band.

Also according to post #3 in this thread, UG roms were meant for North America and XX were for Europe. You can flash any base band you want and check what works for you.
[Samsung Galaxy Nexus] Carlos_Manuel:
I used IMM76I, now I'm using IMM48 or what it is with UGLC1 baseband radio + boot loader, but still I have bad battery so I have to flash other Kernel.. :/

I have no I idea anymore that how I can fix my GN!

I hope that from Samsung they can help tomorrow.. because I'm going to Estonia at Friday and then I need to have good battery life or I have to use ZTE Blade! :D

Is UGLC1 North American baseband radio?
[Samsung Galaxy Nexus] urinsane:
No offense, but you are obviously flashing new basebands/kernels at least once a day, correct?

When they say stop using task manager, that doesn't mean stop using it for a few hours. Try it for a few DAYS, without changing anything else, and then move on to the next possible culprit.

As I mentioned earlier, you are going to continue having battery problems until you give your phone some time to adjust. In my experience it takes a few battery cycles before you can judge how well the changes you have made are working. Several people are trying to help but if you don't give the changes time, you will likely never be happy.
[Samsung Galaxy Nexus] Carlos_Manuel:
I don't have time to wait!

Waiting does not make it better, with wrong baseband/boot loader I have bad battery life and I can't fix it, on Eaglesblood 4.0.3 ROM I had very good battery life!

I'm not using Advanced task killer anymore and I don't see any differences, battery drains still fast!

Also my Nexus Charging time is 4 hours to get battery 99% full, is it normal? it should take only 3 hours!

when I was in shop center then every 5 minute I had 1-3% less battery life, I didn't even use my GN!

and GPS didn't work correctly!
[Samsung Galaxy Nexus] :
Welcome to the German GNex family :-)

uglc1 is absolutely fine for me with o2 Germany

[Samsung Galaxy Nexus] maniac2403:
Few of my suggestions:

1. Don't use any task killer, manager in ICS. It just uses extra battery to relaunch the killed applications.

2. Nexus fast charge can take between 3-4 hours, to charge to 96%, after that you could use Bump Charging or BLX which adds to the battery charge time.

3. Battery drain is related to a bad app/kernel. Install battery saving kernel and see which of your apps is killing your battery. Post Battery Settings screenshots or wakelocks from BetterBatteryStats.

4. Any baseband starting with UG is meant for North America.

5. If it's a new phone, charge the phone overnight, and then use it for a couple of days. After a couple charge-discharge cycles, you would get much stable battery life.

6. GPS works fine for me.

Looking at whatever you posted, you might have a faulty device. But be sure and try everything.

When I flashed my radio to UGLC1 using CM the signal was still pretty week and couldn't get 4G indoors. When I flashed it back to XXLA2 and then back to UGLC1 using fastboot, the signal increased and I am able to get 4G indoors.

Does anyone get a stronger signal when flashing using fastboot?
[Samsung Galaxy Nexus] Carlos_Manuel:
Ok, Thanks!

from DNA store (In Finland) they said that the baseband version on GN GSM on Finland is UGLC1 but it is not for europe so I don't know which baseband radio is good for my GN so I use UGLC1 until I get help from Samsung!

:)

I'm charging My Gn now and I flashed Jame Bond 3.1.7 kernel to it to save battery!

I try to find battery information apps to get more accurate information which uses my battery!

also in Google play store the Ril app does not work on my GN but is should work on GN GSM, is there any way to fix it? it says that my GN is not rooted but I have rooted my GN and I'm using SuperSU ap, is there any app that tells me which is the best baseband version for my country? :)

Thanks again for helping...
[Samsung Galaxy Nexus] airognol:
I'm running AOKP M5 and Franco Milestone 3 on AT&T in South Texas. Could anybody recommend me a good radio?

Edit: Running on a GSM Nexus.
[Samsung Galaxy Nexus] Mach3.2:
Yup, i flashed cwm using fastboot, will check it out this weekend.
[Samsung Galaxy Nexus] josteink:
Why would you otherwise be in the GSM radio thread? :P

Seriously though. Just try any of the newer ones. I hear good things about UGLC1, which is a North American radio as well. In Europe XXKL1 serves me well.

Just try some. It comes at absolutely zero cost and switching radios is extremely quick.

Edit: For best results, make sure you are using a kernel (unlike stock AOKP M5 kernel) which doesn't have the data-lock bug, but includes the fixes from Google's recent updates. I have no idea about Franco's kernel but latest Trinity-kernel works for me.
[Samsung Galaxy Nexus] castaway1:
i hope this will work with o2 Slovakia too :)
[Samsung Galaxy Nexus] Langduscher:
OK so I had a peek in my "service menu" and found out that my GSM GNex was on WCMDA preferred.

So I changed that setting to GSM auto PRL but that setting doesn't stick. Each time when I go back in the hidden service menu the setting is on WCMDA preferred again :confused:

How to permanently change that? I'm on the XXLA2 radio
[Samsung Galaxy Nexus] Carlos_Manuel:
I still have bad battery life, I even didn't use my GN!

In Samsung (Finland) they said flashing to other ROM that is illegal, WTF?

Nobody can't help me, in stores/samsunf (finland), they don't know nothing about Build version and the baseband version! they says that needs to do hard reset!

Anyone who have Finnish GN or Estonian GN, tell me please what is the stock ROM baseband and build version and if possible then the bootloader too!

Thanks!
[Samsung Galaxy Nexus] maniac2403:
Go to a phone store and play with a GNEX. Find out what ROM version and baseband they are using.
[Samsung Galaxy Nexus] Milamber33:
Technically flashing a ROM or replacement kernel is not illegal, but it DOES void your warranty. If you get it all back to stock, they won't know the difference, though.
[Samsung Galaxy Nexus] Carlos_Manuel:
I tried but nowhere is Gnex to check that out, tomorrow I'll go to Estonia and if i have time then I ask from some phone stores...

:)

---------- Post added at 06:52 PM ---------- Previous post was at 06:50 PM ----------

Yeah I know! :)

my warranty is gone and that does not mind me if I just get battery to work correctly! :D

---------- Post added at 07:45 PM ---------- Previous post was at 06:52 PM ----------

I flashed to ITL41F with bootloader: bootloader-maguro-primekl01 and baseband XXKK1..

Now it looks like I have better battery charging and maybe I have fixed my battery life (I'm not sure)..

Only that is bad ITL41F have update to 4.0.2 but not to 4.0.3/4.0.4, so Is there anybody who can update it to 4.0.4 unofficially...? :D

EDIT: this ROM: ITL41F and XXKK1 is on Finnish Galaxy Nexus GSM! :)

I changed bootloader so I have now much better battery charging but about battery life I don't know yet.. (Battery charges 80% faster)!!!!!
[Samsung Galaxy Nexus] sk3201:
How can a bootloader affect battery charging? Just asking....
[Samsung Galaxy Nexus] Carlos_Manuel:
There is many bootloaders for many different Basebands!

Wrong bootloader with wrong baseband radio causes bad battery (I think so)!

I still have little bit bad battery life so I have to flash other Kernel!

or I just have to charge it to 100% and then drain it and charge again... :confused:
[Samsung Galaxy Nexus] maniac2403:
Bootloader has no effect on battery life. The task of boot loader is to start the operating system. It has no play after that. Bad radio can cause poor battery, but not a bootloader. A bad bootloader will not let you boot.
[Samsung Galaxy Nexus] sk3201:
Thats what I thought...
[Samsung Galaxy Nexus] quietriot84:
What version of ICS are you running? What is the build number? I noticed in your last screen shot that you were not connected to the Google servers, as your bars are grey and not blue.

I had bad battery life on ICS build IMM76D due to the radio shutting down when the phone went into sleep mode, and it would take about 20 seconds for the radio to come back on and connect back to google servers. Google released an update to IMM76I and that resolved my issues.
[Samsung Galaxy Nexus] pakjebakmeel:
http://en.wikipedia.org/wiki/W-CDMA_(UMTS)

Still want to disable that? I think if you manage to get that setting stick you will effectively disable UMTS and head back to GPRS?
[Samsung Galaxy Nexus] Mach3.2:
Not sure how to make it GSM auto PRL, but you can make it GSM only.

Settings > More > Mobile Network

Check "Use only 2G network."
[Samsung Galaxy Nexus] josteink:
This is a myth and has been debunked several times (even in this thread).

Any proof to the opposite has yet to be delivered.
[Samsung Galaxy Nexus] efrant:
He is not asking to disable WCDMA - he is asking how to make it stay on GSM auto.

The difference between "WCDMA preferred" and "GSM auto" is that the former will preferred 3G over 2G, while the latter will prefer 2G over 3G.
[Samsung Galaxy Nexus] mrfleetwood:
I'd prefer XXKK6 over it:

"XXKK1: - Not recommended for any firmwares/ROMs above 4.0.1"

The current baseband for 4.0.3 is XXLA2 in Finland, which has absolutely no battery drain problems in my phone. Also XXKK6 might be a good choice.
[Samsung Galaxy Nexus] lillypad_33:
Wow...

I just flashed UGLC1.

I'm in Canada ( ontario ) on the Bell network.

On UGKL1 I was at around -93db

I did a speed test and got 2041 down and 541 up

then I flashed

I am at around -77db

I did a speed test and got 5048 down and 1165 up.
[Samsung Galaxy Nexus] pakjebakmeel:
Uhhh, yes but 2G is available virtually anywhere whereas 3G is more of an added luxery. Wouldn't preferring 2G effectively disable 3G? I mean, what's the definition of "preferred" in this case? If that means it will connect 2G if available regardless of whether 3G is available that would mean it will never connect 3G. If 3G is available then 99/100 2G is available too but if 2G is available that doesn't mean that 3G is available too. So to cut a long story short; would it pick 2G aka GPRS in those 99/100 occasions?

And as far as I know if you switch to 2G you won't get anything better then GPRS which yields 4kB/s to 6kB/s.. Might be wrong here, perhaps it has some intelligent mechanism that prefers 2G and switches to 3G as data is transferred or something? Can't image as the switch isn't quite seemless..
[Samsung Galaxy Nexus] Thracks:
It will prefer 2G in the sense that the connection is more likely to roll over to 2G, rather than cling desperately to one lousy bar of 3G/H+ at the expense of your battery life.
[Samsung Galaxy Nexus] efrant:
No. Preferred in this case relates to when the 3G signal is weak. Both setting will use 3G, however when the 3G signal is weak, one will hold on to it as much as possible, while the other will fall back to 2G quicker.

Additionally, in this case, EDGE falls under the second setting as well, so it's not just GPRS; EDGE is included as well.

And yes, the hand-off is absolutely seamless.
[Samsung Galaxy Nexus] Carlos_Manuel:
My GN still have still battery drain problem, I sent it to phone service so they'll fix the problem...

:)

I didn't lock boot loader so I hope it still have guarantee... :D

on IMM76I 4.0.4 ROM battery was only 1% left after 8 hours, I used only Google Maps few times to find right places and in ship I used WiFi when I needed it..

I flashed back to stock ROM which had XXKK1 baseband and with that I had same fast battery drain...
[Samsung Galaxy Nexus] francis1212:
After flashing a new ROM, my reception icons turn greyish?

My new ROM is 4.0.4 Gummy_maguro-Release-1.0.1

Original Baseband version is I9250XXKK6

Kernel Version is 3.0.27 imoseyon 2.2.2

The greyish icons once in blue after flashing, but after few hours they turn grey and never blue again.

I tried to flash the radio again using this http://xdaforums.com/showthread.php?t=1374077 through CWM, yet it was aborted and failed...

So, anyone can help?

Thanks a lot!!!
[Samsung Galaxy Nexus] mrfleetwood:
Hm, I just flashed XXKK6 through CWM yesterday and had no problems at all. Downloaded the file from the link of the 2nd post in this thread. Maybe you should try to download the file using those links and try again.

My rom is AOKP 4.0.4 and had XXLA2 but encountered too many dropouts with it. XXKK6 seems to work much better.
[Samsung Galaxy Nexus] Carlos_Manuel:
maybe that radio is not flash-able on CWM!

try this: http://minus.com/mwEmSTqAX/7f it's XXKK6 baseband radio and it can be flashed in Clockworkmod
[Samsung Galaxy Nexus] efrant:
Guys, all the radios are posted in the first few posts of this thread in CWM-flashable format...
[Samsung Galaxy Nexus] francis1212:
Thanks a lot you guys!!

This radio is flashable.

However, those reception icons are still greyish...
[Samsung Galaxy Nexus] colocynth:
They are grey means your phone is not connected with Google servers. Try other basebands.

Edit - I am in Hong Kong. Xxla2 gives me good connection with g servers.
[Samsung Galaxy Nexus] josteink:
Lol. You'd think that would be obvious, but I guess page 1 is getting pretty far away now. Easy to forget where and why a thread started :p
[Samsung Galaxy Nexus] francis1212:
Thanks!! I tried to reflash the rom, they become blue again! Let's wait and see if the problem happens again in coming hours. So far gummy rom works so well :D

Thanks for your suggestion. If the icons turn grey again, I will try your xxla2.
[Samsung Galaxy Nexus] Archpope:
So, as I understand it, the XX in XXLA2 means that it designed for European phones, which I presume means favoring 900/1800 towers, whilst the UG in UGLC1 means it's for North American phones, favoring 850/1900 towers. I bought my GNex from the Google Play store, and this leads me to wonder: Why did Google sell a phone with European basebands from a site that only ships to the US?

In the week that I've had my phone, I've noticed that while signal strength out and about was great, building penetration was terrible. In many local businesses, I was not able to get a signal at all whereas many of my friends were able to get reasonably fast connection speeds. It was like the phone wasn't even *trying* to use the 850 band, and my two-year-old Galaxy S did a much better job of it.

My search for answers led me here. I have just updated my rooted, but otherwise stock, GNex to UGLC1. I've not left the house yet, but I am already getting two more signal bars at home than I did before. I'll have to see how it is when I go somewhere else, but if this does fix my problems, it's actually a pretty big FAIL on Google's part.
[Samsung Galaxy Nexus] maniac2403:
Yep, looks that way ain't it? I wonder how did Google ship their devices with European basebands. They should ideally work but not the best reception. I am on UGLC4, but every time I visit Europe or Asia, I flash different radios.
[Samsung Galaxy Nexus] josteink:
I'm just guessing here and I have no hard data to back this up, but it might be because the GSM model is mostly sold in Europe and that most US customers for one reason or another favour carrier-phones and was waiting for the CDMA carrier-nexuses.
[Samsung Galaxy Nexus] ygvuhb:
hi any apps can record all signal dBm and tower id change?

i cannot find in market, will anyone build one?

it will be the best tools to compare different radio performance

and is the kernel is another key for affect radio signal receiving

or may be the key of control dual band charging behavior

i use faux's kernel recently

when using 17b2 (aokp m5 + xxla2) it got the best signal and prefer to stay at 3g 900mhz instead. of 2100mhz(bad data connection in my office)

i don't know why

so hope i can find a app to record all signal dBm and tower id change to find out is it really improve by kernel or not
[Samsung Galaxy Nexus] Milamber33:
Try OpenSignalMaps. It does all that and more.
[Samsung Galaxy Nexus] ygvuhb:
thanks it can record the dBm change with graph

but cannot record tower id change record with time only show the current tower id

i find this in play store but it is not support our galaxy nexus

but it have a bug

after i open the app, then turn off screen

it will auto turn on the screen, and then phone loop turn.on and turn off screen

another problem is my LAC & CID is 11031 25444

but in the csv it show 11031 6775652

please help thanks
[Samsung Galaxy Nexus] efrant:
I'm using XXLA2 in North America with no issues whatsoever.
[Samsung Galaxy Nexus] zivan56:
For #1, that's normal. If the screen turns off, Android stops updating the cellid. It is a bug filed with Google since the early days of Android which they still have not fixed. So I make sure it stays on. There is no way to keep it on at the lock screen except for flashing on/off. You can use the blank screen mode to save battery/prevent pressing buttons.

It really also depends on the phone, on Motorola phones it will not flash on/off.

For #2, that is correct. The cell id provided by Android includes the cellid in the bottom 16 bits and BSIC in the upper remaining bits. I split those two into an easy to view format on the GUI, but write the "real" cellid in the CSV.

You can do some math in Excel to remove the BSIC, just do the value mod 65536 and it will give you what you see in the GUI. I believe its =MOD(column, 65536)
[Samsung Galaxy Nexus] ygvuhb:

I just flashed back to XXLA2 and now I'm barely getting 2 down speeds, has this happened to anyone before? I'm in the exact same spot as last night by the way. So I tried to flash back UGLC1 and now I'm barely pulling 2 down on that also where I was just pulling over 3 down on it a few minutes ago. Ideas?
[Samsung Galaxy Nexus] fortesquieu:
Maybe the tower that you were using got congested? There are many variables.

[Samsung Galaxy Nexus] colocynth:
My carrier is able to provide a higher speed. But, I subscribe to a cheaper srvice, about max 400kbps. My phone often show me hspa +.

Should I limit my band to GSM only? Is GSM good enough for 400kbps? Will it save battery?
[Samsung Galaxy Nexus] xur17:
I believe gsm has a lower limit than 400kbps. Also, hspa has lower latency than gsm.
[Samsung Galaxy Nexus] efrant:
The max throughput on EDGE is 384 kbps, but I doubt you will ever reach that.

A Really Basic Radio Question

I see mentioned at the beginning of the thread that XX basebands are from Europe and UG basebands are from North America. So this leads me to a few basic questions i have not seen mentioned in this thread:

1. What is the real difference in these basebands, does it relate to the GSM bands that are run in those Regions. What really makes XX basebands Euro friendly?

2. I am in Indonesia and can do trial and error to see what works best but it would be more interesting to me if i know what the underlying factors I am dealing with instead of just getting lucky somehow. If i know that Indo is using basebands 900 & 1,800 with 2,100 3G, how can i determine what is the best baseband for coverage AND battery life?
