[Baseband/Radio] UGKL1

This radio is for GSM Galaxy Nexus devices running Android 4.0.3-based ROMs (IML74K).
I have uploaded the UGKL1 baseband, which has indeed appeared as a post in other threads, but has not received a concise thread of its own. As implied by the file name, it can be flashed with CWM.
In my testing, it improved my HSPA performance over UGKK7, but of course your mileage may vary.
DOWNLOAD: HERE or HERE
MD5 SUM: 41b17cc37ceb6c57fed17dc90d6d7f39
Deciphering Samsung baseband codes:
UG = North America
XX = Europe
K = 2011 (11th letter of the alphabet)
L = December (12th letter of the alphabet)
# = Revision number
This means the radio is approximately one month newer than UGKK7, which breaks down to a North American radio from November, 2011.
//EDIT: Support confirmed for 850/1900/AWS via Rogers Canada and Mobilicity SIMs.

NOTE TO WIND MOBILE USERS:
as I've mentioned before, this radio causes problem for users on Wind Mobile. It does not detect roaming as roaming & will not shut off data roaming even if the option itself is turned off. This means that users will be getting HUGE phone bills. My Galaxy Nexus came with this radio default so I had to flash the XXKK6 radio to fix the issue. Just putting this out there as an FYI for everyone.
The only downside is that this baseband (KL1) has better reception than XXKK6
I am not alone in having this problem as there is a whole thread full of people having the same issue. I was the one who figured out the fix for everyone
I had the same problems with the UGKK7 radio as well, but again flashing the XXKK6 radio fixed the issue. So far i've only seen Wind Mobile users having this problem.
Here's proof:

Anyone know how this performs on tmo us? XXKK6 seems to give me the best results

I can confirm that UGKK7 hasn't given me any roaming issues nor extra charges in the couple weeks i've been using it with WIND, although my Virgin Mobile phone originally came with UGKL1 (another great reason bootloader unlocking should be allowed on every phone!).
What advantages do you find with KK6 over KK7? I've noticed slightly more reliable signal and speed going from KK6 to KK7 but would switch back if you believe the roaming issue prevails. Could it just be that I manually chose WIND Home instead of auto select?

Yes the manual select would prevent roaming/Try auto & see if it roams onto wind away but doesn't detect it as roaming

can u pls upload to dropbox or some other site? its not downloading right.

Maybe it's my device, but every time I download the file it fails the md5 check.

Well I just installed KK6 again and it's not working well at all... suddenly my download speed is almost half and it barely uploads. It's the same room where it was working a lot faster with KK7 so I think I may switch back and just manually select WIND Home like before.
If I'm doing that anyway could I just do that with KL1 too? I don't plan on roaming anytime soon so manually setting WIND Home would be ok?

KL1 was terrible for me on T-Mobile US. I wrote a bit about it in the KK7 thread.

Yeah, as I mentioned, KL1 has better reception on the "Wind Mobile" network than XXKK6 but the roaming issue is a pain in the ass. I didn't like switching to XXKK6, I just had to
If you don't care about roaming or are manually selecting network u should be ok. Call Wind back office & ask them to disable roaming. That way if by any chance it does roam then u aren't responsible.

Verizon's Galaxy Nexus is the SCH-i515, a completely different model than the GSM version, the GT-i9250. You're also on the GSM development forum; which phone do you think this radio is for?

Actually this Radio performs absolutely terrible on Rogers in Calgary and Rogers in Vancouver compared to XXKK6. I would defiantly not go as far as to say specifically for Canada.
Radios are very much trial and error, what works for some won't work for others.

Australian Galaxy nexus bad signal and drop outs

I just received the galaxy nexus and got it from optus Australia, ever since geting it 4 days ago the reception keeps dropping out and data fails to work at optimal speed as it used to in my HTC wildfire or my iPhone 4, I've flashed android revolution hd , kang, and currently using foxhound and all have updated apns. Wonder is my device just a doggy one or is everyone else in Australia getting the some problem?

Try putting a different baseband on your phone. You should be able to find your countries carrier on the forums here. Just search.

LMAO! Rough man.
On-topic though, all good with mine on Telstra bud. Have you tried the latest APN at Ausdroid? Not sure if the Optus one has been updated recently... May also work if you try setting your radio to AUS by default, link and how-to coming shortly (I'll just find it).

haha im with telstra, brought it from optus.

do you happen to have any links to the baseband download? thanks.

I figured that as soon as I posted You should resurrect that Australian traders' thread in the MP.
- Go to the Dialer
- Dial *#*#4636#*#*, go to Phone Information
- Press MENU, "Select Radio Band" and select AUS2
- Reboot for good measure
This is supposed to optimise your radio to maximise use of the 850MHz band and stop it hopping off to 2100MHz in Metro areas.
Also use the following APN settings:
Name: Telstra Internet
APN: telstra.internet
MCC: 505
MNC: 01
Authentication: PAP or CHAP
APN type: internet
Some people recommend putting 'wap.telstra.com/wap' in the Server field. You should only use this if you need the Telstra portal, otherwise it just adds another link into the chain that isn't really necessary. TelstraOne will work just fine without it.
Let me know how you get on.

Yeh I've got same problem but after the update to 4.0.2 it got slightly better , I'm also on optus but got my phone from mobicity.
Its little annoying.

Not necessarily. Perhaps flashing the DVKK6 baseband (Telstra) may help. Unsure. If it has an Optus radio they may have done something to prevent it favouring 850MHz. This is just speculation on my part dude, it works fine on my Telstra unit. Perhaps this is one of the 'optimisations' Telstra made on their model.

No worries man, I hope it goes a bit better for you. I'm rural and getting 3.3mbps down, 1.2mbps up which is marginally better than my Galaxy Note. Considering I'm probably on a 5.7 or 7.2mbps backend, that's pretty good. No drop-outs either.
Good luck buddy.

Make sure you use the trimmed .img in post 6, not the one from the OP. Unzip it first (before you try and flash it) as it contains the MD5 hash also and this will stop the process (or worse).
Use fastboot to push it to your Nexus.

alright, thanks, it worked! thanks juzz! number 1 to come to! haha, ill see how i go with reception for the week. Cheers.

You may need to change your SMSC buddy. I think it's in the menu where you change the radio to AUS2. I'll need to look up the correct number for you once I get to work. Sit tight man
EDIT: Okay. Enter the *#*#4363#*#* code, then go into phone info. Scroll to the bottom, you will see a field for SMSC. Refresh the field, and see what it contains. Mine is this:
07911614786007f0
You could try putting this in if yours is different. Let me know how you get on.

That's fine. It will only handoff to GSM where there's no 3G. As long as you're on AUS2, preferred order is 850, 2100, GSM

Best Radio for T-Mobile??

I have searched through numerous threads but found mixed answers...
Some say to use european version and some say use North America based radios...
I am currently using the XXKK6 right now and the performance is "OK" but I have feeling it CAN be better...
I live in NYC and T-Mobile service is pretty good out here... Please let me know which radios work the best in your opinion.
Currently running stock Yakju 4.0.4 with unlocked bootloader.

Try XXLA2 considering that is the latest out with the recent yakju OTA. I myself have not seen any major/significant boost to signal strength nor data speeds since my signal here is always superb.

I was using that one on TMob in Atlanta on 4.0.2 until my OTA came in last now. Now I'm 4.0.4 with XXLA2 and its a lot stronger.
I have my radios set to US version, not automatic if that helps.

UGLC1 is better than XXLA2 for me. NYC as well.

UGCL1, Where can I find this? Its not in the http://forum.xda-developers.com/showthread.php?t=1405345 Thread....

v4.0.2 and XXKK6 radio with Tmobile here in San Francisco. No call quality or data speed complaints to report. Fwiw I don't work inside a big building office type settings.
I seen Speedtest downloads from 1mbps to 7mbps and uploads from 1mbps to 3mbps. Performance often depends on location and variable network saturation levels.

I'm on XXLA2 and it seems great T-Mo in WA.

yes changing radios will improve/worsen your data speed.
you have to fastboot flash it... i believe you have to be bootloader unlocked to manually flash these images via bootloader mode.
follow the ROOT guide without using any tool kits (the process of.... fastboot oem unlock) ... just don't root, after its unlocked then type
fastboot flash radio <radioname>.img (make sure its set in your SDK folder). you can find this by googling it / searching it within XDA

That is NOT the latest North America radio. The latest is UGLC1.
UGLC1 > UGLA4 for me.

i'm on UGKL1 and it has been great for me. gotten up to 8Mbps down and 3Mbps up and great service almost everywhere. except places where i've always gotten bad service.
Any reason for me to upgrade to the latest? which i guess is UGLC1?

i am T-Mobile in NYC area and noticed that UGLC1 took really long to regain signal / service when getting out of subway. it was noticeably slower... It was actually longer than the XXLA2. I am flashing UGLA4 now and will report my findings

The phone actually gets weak signal and lost of connection everywhere. But since at my house i don't have a GREAT! signal it just vanishes.
The phone was Stock when i bought it and had the Issue it came with XXLA2 Radio and 4.0.4 Lastest ICS Build.
After i noticed the issue i rooted and tried all the radios available and roms with no luck. all leave me with low signal.
I sued to have a GS2 and had 2 to 3 bars at home so its a huge difference .
Now iam running JB 4.1.1 with latest Radio XXLF1 and same issue,
Something i have noticed is that the phone has Very high dBm... compared to other phones from same Provider.
FYI i live in Puerto Rico and the provider is Claro.

Same problem here with baseband XXLA2 and build IMM76I.
I know there were signal issues with updates from 4.0.2 to 4.0.4 (see here but, if I have understood well, the build IMM76I should have solved that problems.
So the question is: my phone has come out with 4.0.4, XXLA2 and build IMM76I (so already with the fix for signal problems) what could be the problem? Hardware??

I'm planning to test some other radio and also intall the JB OTA. I will keep you updated.

Crap! Just updated to 4.1.1 via OTA and the problem is still there! I'm experiencing 10 - 20db less in signal strength than the one I have with a gs2.The baseband now is XXLF1. So I have to assume that is an hw defect and send it to repair? Is anyone experiencing this annoying issue?

I had this happen to a white unlocked GSM Galaxy Nexus i purchased. I ended up just sending it in for a replacement. \o/
Seems to be hardware related.

I wonder If there is a way to fix the phone.. If i just knew what piece of hardware is and if it is worth it... I bought it 2nd Hand and dont think its under warranty. Does some one knows where i can send it for repairs to samsung??

I'm more or less in your same situation. Before sending it to repair I would like to know the signal strength from the ones that are not experiencing this kind of problems (just to compare with mine and for being sure that is my radio with some weird issue).
So can anybody please tell me, in average, which is the signal strength experienced especially in closed spaces (e.g. at home, at office, etc.). I' have a range between -100db and -115db.
PS with your invoice I think that you can ship it directly to a samsung center for repair.

I just sent an email to Samsung support to see what they will do. My phone never goes above -90 and I've had drops in the city where I've never had problems before. My BB sitting right beside my GNex says -77 and the gnex says -95, iphone says like -84... I'm going to see about getting a replacement or something from Samsung.

I have the same Problem ...it´s definately the 4.0.4 ROM ... I sent my GNEX to the support 2 weeks ago and I got it back with an 4.0.1. ROM. But I did the update again . After that I had the signal problem again... and the hotline said to me please don´t update!
I don´t think that it is the Baseband or the Hardware... it must be the ROm or the Kernel.

I don't see anything strange.... You are experiencing exactly my same problems.... I haven't seen any sw solution to this yet... Probably I'm going to send my phone to repair.

not really. I have tried different radio still getting low speed. before I changed radio I have 3-5 Mbps, now can only reach 0.23 Mbps. I still don't know the problem is with radio or the data service. I actually have simple mobile. Their service is not good. Their advertising said the service is unlimited 4g speed no throttle so I signed up. I called customer service and they told me my account is normal. I may have to wait until end of month to get T-Mobile 4g to test my phone.
I have tried north America radio and takju radio, UG and XX. I'm using android 4.2 takju.
are you having any issue with radio? which service you have?
