[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.

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?

Added another download source and moved it to the primary position. MD5 sum confirmed correct.

I've had good results with UGKK7 but will try this out. Where in North America are you located?

KL1 was terrible for me on T-Mobile US. I wrote a bit about it in the KK7 thread.
I've reverted back to KK7.

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.

Is this the best radio to use if I'm running a GSM nexus on AT&T USA? Or does "north america" mean for verizon nexus users?

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.

Calling all At&t users with a custom 4.0.3 rom installed.

I know Google recommends xxkk6 or UGkk6 with 4.0.3 however I get abysmal battery life with xxkk6 and I get frequent cell service drops with the stock xxkk1 radio.
What radio are you guys using?

xx seems to work better with AWS/1700 bands. Try the UGKK7 and UGKL1 basebands. Those were designed for canadian carriers which should use the same bands as AT&T.

T-Mobile user here, but considering the phone isn't out here we're pretty much all in the same boat. I've tried XXKK1/6 and UGKL1/KK7, and UGKL1 was by far the best reception for me. My buddy on AT&T said the same. UG designated radios are North American.

My phone came with XXKK1, and when I unlocked the bootloader and switched to a 4.03 ROM, I switched to UGKL1. While I'm getting less "bars" than I used to with my Motorola Milestone, my actual signal strength is about the same (-60dbm in great areas, -90 in my house). I feel like UGKL1 is slightly better, but its tough to say.

[Baseband/Radio] DVLF1 (Telstra GSM)

Attached below are fastboot and CWM images for a new radio that I just extracted from the Telstra 4.01 -> 4.04 OTA that was released yesterday.
The radio is DVLF1 (I9250TDVLF1) and has not been seen before.
This radio is best suited to 850mhz 3G networks.

radio-maguro-i9250t-dvlf1.img.zip MD5: 8CC3D43867076EE028BF758BD7B37F94
Only been running it for an hour so far and seems OK, but will post further feedback after a few days.

But why? Just go Yakju... Telstra suck at updates

It's a Telstra radio, not the Telstra ROM. I've been yakju since day 1.. I flashed Telstra's ROM just to grab the new radio. DVKK6 has been awesome on Telstra, and the JB XXLF1 radio was terrible. Telstra users looking for the best radio may wish to try it, that is why.

Thanks for doing this!

So, just to confirm.. you're using this just fine with Jelly Bean?

Friends .. My baseband is i9250XXKK6 ... If I install this radio... is that worth... sorry... till today I dint flash any radio... is there any way to get my current radio backed up ?

You can find a backup here. Keep in mind that unless your carrier uses the 850MHz frequency, the stock JB radio might be better for you.

And you seem to be right, I'm on T-mobile here in the U.S. using AWS 1700/2100Mhz and this radio just plain sucks for me, it refuses to pick up 3G for me in my room where I get a good 3G signal, so I flashed back the stock Jelly Bean Radio XXFL1

Telstra's network uses 850mhz so should be fine on that band. Personally I'd only recommend this radio for Australian Telstra users.

Can you please also pull and post the RIL, it makes sense to have them matched..you can find it in

Much appreciated.

Yeah no worries. I had already ripped it but hadn't gotten around to posting it yet. Here's the RIL zipped, and also a flashable CWM zip.

MD5 for the CWM zip: 652F2DACB2D755840ADE251C32321C81
Based on that MD5, it looks like it's the same RIL as XXLA2.

The original Telstra radio DVKK6 is awesome on 850mhz and the jury is still out on whether this new radio is any better, so if you're happy with that.. I don't see any reason to change.
From 24 hours use, this new radio seems very similar to DVKK6 and is performing well.. but it's not like there is a massive performance difference.

living in Panama on Cable and Wireless (850),this radio is a big jump. Going from -85db to -53db, after flashing and reboot.
Thank you very much

I just installed this radio and now I can't send SMS .....but I'm not 100% sure I didn't mess with a setting with 4636....can someone help with setting etc? Telstra in Melbourne, if that makes a difference.

Back to XXLF1 for me...
Gave this a try on 4.1.1 (Bigxie) but the reception on 3G was at least 10dBm lower (97+ vs 80-) throughout my tests, and it never left "3G" mode. Never switched to "H." Transfer rates were much slower, too - barely 1Mbps down, 100K up. Minutes later, 1.8Mbps down and 1M up on XXLF1.
It DID boot in the correct mode though - WCDMA Preferred.
The "International" JB radio/RIL works better for me; never had an issue with it, so I'm back on it.
Note: I did change the RIL to match the radio, so maybe if someone else tries this radio on JB they should keep the JB RIL and see if it makes a difference. I am in a congested cell, btw.
YMMV.

I suspect you've changed something in the service menu. Your SMSC might be incorrect. Try the fix below.
Telstra's SMSC is+61418706700 which must be entered in PDU format:07911614786007F0
- Open dialer
- Type *#*#4636#*#* then click on 'phone information', then scroll down to 'SMSC'
- click 'refresh'. If it is not 07911614786007F0, type it in and click on 'update'.
- Reboot.

Not really. All it does is help me with what radios are new and old. Not many people are saying where, geologically they are located. That's what this thread is for. The Geo of fellow members to better know which radio works best for your backyard. Not saying the other thread isn't working. Just want to get a better knowledge with Geo locations.

Flash some different radios and see how the reception is. Since things change so drastically from phone to phone and area to area, the best thing to do is try it yourself and see what works best.

Went ahead and gave UILE1 + XXLF1 (RIL) a try once more. So far pleased now.. came out with better results than I was having 2 days ago. Results came to look as the Upload kept capping @ 1.75 and Capping @ 5.33 for DL..

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?
