Look at the RIL link in my signature. I've packaged most of them there.

The actual file you're replacing is /system/vendor/lib/libsec-ril.so

Edit: ninja'd by 3rdstring. :D
[Samsung Galaxy Nexus] Gucci.Nexus:
I really like this thread. Great community. Thanks JZ and Efrant! Fingers crossed this new radio and ril will get me service in my apartment. I am on Telus in Victoria, Canada.

Edit: so far no noticeable improvement.

Is there any chance flashing the ROM as well could help with reception?
[Samsung Galaxy Nexus] Quidlor:
Thanks efrant and 3rdstring. So basically when returning back to UGLC1 I would simply copy the image back over as well as the libsec-ril.so file and that's all?

Sounds simple enough.

Thanks!
[Samsung Galaxy Nexus] efrant:
No, the flashable zips I created will put the file in the correct spot and apply the correct permissions.

If you want the UGLH1 RIL, just flash the UGLH1 RIL zip. If you want the UGLC1 RIL, just flash the UGLC1 RIL zip.

Edit: sorry, I misread. Yes you could do that. But don't forget to set the permissions on the ril file to 0644 after you copy it over.
[Samsung Galaxy Nexus] greeced:
I realize that, just wondering if any other performance improvements may have been made.
[Samsung Galaxy Nexus] sliceruk:
Just flashed UGLH1 - hopefully it will work properly. With XXLF1 I had problems for ex if I would go in the elevator and then come out - it would loose connection and not connect again. :eek:
[Samsung Galaxy Nexus] osm0sis:
Wow! Thanks to jz687 and efrant for bringing the new yakjuux build to light! I'm happily yakju but I like to hold on to the newest yakjuux build in case I need to warranty my phone. Any idea what the bootloader that came with it was? Stock JRO03C?

I'm also curious to hear whether NFC is working on yakjuux again now that's it's updated to JB, as it hadn't been in IMM48...
[Samsung Galaxy Nexus] efrant:
Bootloader is LA03 (not new).

Not sure about NFC. I haven't flashed this build, and don't plan to -- I'm happy with takju.
[Samsung Galaxy Nexus] osm0sis:
Thanks for the info! Odd that they would update it to the bootloader from IMM76I (ICS) and not JRO03C (JB).
[Samsung Galaxy Nexus] dajoker89:
I sent my Telus GNex in for repair with yakju on it instead of yakjuux, I didn't even think of switching back before I sent it in. It is currently being repaired by Samsung. I will let you know if I encounter any problems.
[Samsung Galaxy Nexus] efrant:
Quite a few folks (including some from Canada) have sent in their devices with non-yakjuux ROMs, and have had no issues with warranty.
[Samsung Galaxy Nexus] osm0sis:
On the other hand, Telus told me unlocking my bootloader and rooting my phone would void my warranty through them, so better safe than sorry.

Edit: Just gave the yakjuux JRO03C a quick test-drive and can confirm that NFC is back (!!!), hopefully in working order, and it also comes with Chrome pre-installed, which is interesting seeing as I don't think takju or yakju do. Hopefully this gets pushed OTA soon to all the angry, neglected Canadian GNex users who still haven't made the switch to yakju. :)
[Samsung Galaxy Nexus] patrickdo:
Is this designed to work in southern California, USA?
[Samsung Galaxy Nexus] efrant:
It will work fine in SoCal.
[Samsung Galaxy Nexus] Gucci.Nexus:
Anyone getting better signal results? Not me. Xxlf1 has been best for me, I think.

Telus, Victoria, Canada

Jellybean 4.1.1
[Samsung Galaxy Nexus] osm0sis:
I'm finding it MAYBE just a little better than XXLF1.

Edit: I take it back.. it's actually performing MUCH better than XXLF1. I've never seen so many bars in my area of the city before! (PEI, for reference :))

Edit 2: I should clarify I mean bars of signal! :laugh:
[Samsung Galaxy Nexus] mertbba:
After flashing the radio and RIL in CWM, I cannot connect to any wifi network. What should i do? It says connecting and immediately goes to saved.
[Samsung Galaxy Nexus] osm0sis:
Wifi has nothing to do with the radio, the wifi driver is in the kernel. Go back to CWM, clear your cache and your dalvik and see if that helps. Sometimes things get hokey.
[Samsung Galaxy Nexus] mertbba:
it worked. thanks a lot.
[Samsung Galaxy Nexus] hiddenhacker:
Hi there:

I’m just new in the XDA. I have few questions regarding nandroid backed up image of Yakjuux Jellybean.

01. As the nandroid backed up image is from different Gnex, would that replace my own device image including my IMEI & Serial, etc.?

02. What should I do as one of my friend has just lost his IMEI that replaced by a generic IMEI? He had to come back to Yakju jellybean!

03. Is there any way that I can flash that nandroid backed up image to have Yakjuux Jellybean without losing my own Gnex identifications?

Thanks a lot guys!
[Samsung Galaxy Nexus] osm0sis:
1) No. 2) What? That makes no sense. 3) Yes. That's how nandroids work.

There is no advantage to using yakjuux over yakju, in fact it's more of a disadvantage, so why bother?

Read the threads linked at the bottom of efrant's signature, starting with Basics and you'll find all you need to know. :)
[Samsung Galaxy Nexus] strumcat:
I've been using the excellent UGLH1 radio and RIL the last few days. It's been performing better than any other radio I've used, including XXLF1. Connections don't get dropped, downloads complete the first time every time, and general throughput seems faster. (This is in the Burbank, CA area).Thanks, jz687 and efrant for making this gem available.

If anyone else would like to try it (recommended) here are links to the attachments in efrant's original messages:

[Samsung Galaxy Nexus] mpgrimes:
i flashed this yesterday, telus alberta, and im not noticing a lot of difference in amount of bars for signal, but data is MUCH faster and MUCH more reliable. its a keeper i think.
[Samsung Galaxy Nexus] strumcat:
That's exactly my experience. I think if more people tried this radio, there'd be a lot more happy campers. I can't understand why there isn't more buzz about it.
[Samsung Galaxy Nexus] osm0sis:
Probably because there hasn't been much buzz in the actual Basebands thread. ;)

I totally agree though; best I've used! Between this and Franco's latest (r248) for fixed JB Wifi drivers everything is great on my Nexus ATM.
[Samsung Galaxy Nexus] msavic6:
When I switched to yakju over the summer I didn't get a chance to test my phones signal in the confines of my concrete school. When I do test it and if it appears to be worse ill try this new radio out, but for now I'm going to stay on my current radio.
[Samsung Galaxy Nexus] xpipa:
i just install on my Minco v4. I'm in italy i must test it in 3 days then i say something. The only tink is that i use h3g and when i had the sgs2 i have an optimized Radio for this operator and in the same place i have more strong signal... but i don't miss my sgs2 ..lol !
[Samsung Galaxy Nexus] hiddenhacker:
Thanks a lot for your quick reply! It was really been helpful!:good:
[Samsung Galaxy Nexus] lafrad:
Flashed this radio this morning... works *great* so far.

CM10 nightly, Franco kernel, TMobile USA

At work, I have strong 3G signal at my desk, only EDGE on the other side of the office in the break room. Before this radio, the handoff from 3G to EDGE and back would drop all data and cause loss of connectivity for several seconds. Sometimes it would take a reboot to re-establish. Now, it will handoff the radio without dropping data connections!

HUGE.
[Samsung Galaxy Nexus] strumcat:
Good luck with your testing. Even though UGxxx radios are supposedly optimized for North America, it will be interesting to see how well it works in Italy.
[Samsung Galaxy Nexus] WoodroweBones:
I havent noticed much in the way of battery life but performance-wise ever since I discovered the RIL and started matching it its been a no-brainer. Absolutely 0 data drops (without matching RIL I found I was having to go into Airplane Mode and back to get data sometimes)

I didnt see it mentioned anywhere in this thread but if you are rooted the app GetRIL is a must have. That way you just flash the radio of your choice then when you get back into your OS just run GetRIL and match them up. Easy peasy.

I have only had this radio for one day but so far it seems to be much better than UGLC1 (the previous best performer on my phone). I am in Winnipeg, MB on the MTS network (same as Rogers towers in many places). When I head back to my hometown next I'll get to do some real testing as there are many places there where my signal is marginal so hopefully this improvement keeps up in those areas as well
[Samsung Galaxy Nexus] shredrex:
I had nothing but problems with any XX radio....I am using the latest now and my signal and data are working great on Rogers.
[Samsung Galaxy Nexus] dalmer:
I just read this thread now, but I had the same ROM and Baseband on my GNex after it went in for repairs. I didn't even notice the new radio until I read this as I was too busy with other things for the last week.

For what it is worth though, I had yakju on it when it went in for repairs (broken USB as well) and it was rooted an unlocked. They had no issues with fixing it under warranty.

As for the new radio, it defiantly has been better in areas with lower reception.
[Samsung Galaxy Nexus] Exostenza:
So the ril file is only useful for people not on 4.1.1 correct?
[Samsung Galaxy Nexus] osm0sis:
Nope, the RIL goes with the corresponding radio. Useful for anyone on any version wanting to use that radio. The RIL that comes with takju/yakju JB is XXLF1, to match the default radio. When you flash another radio, like UGLH1, you then also need to update your RIL to UGLH1 to match.
[Samsung Galaxy Nexus] efrant:
What osm0sis said is correct. I will add one point though: some RILs are identical, (as I was compiling the list, I found that a few of them are exactly the same), and I haven't compared this one to any others
[Samsung Galaxy Nexus] osm0sis:
Yup. :)

Better safe than sorry though. People have reported mismatched RILs degrading their performance (even within this thread, at the top of the page here hehe).

Edit:

MD5s of XXLF1 and UGLH1:

04af518deec07743f27947240694e887 UGLH1-libsec-ril.so
ab5a6749029fbc2507a26aca58920ab4 XXLF1-libsec-ril.so

So they are different. Might explain why people are actually seeing a difference using the correct RIL for this one.

Like I said though, better safe than sorry, so as a general rule you should flash the corresponding RIL when you're changing radios.
[Samsung Galaxy Nexus] gtwannabe:
Terrible

Awful radio. Crippled WIFI (900ms pings and 25kbps speed) and broke Bluetooth. Flashed back to XXLF1 and everything's working normally.
[Samsung Galaxy Nexus] efrant:
I just tried it myself. Couldn't tell the difference between the two. (I never use speed tests though, only go by feel -- if it doesn't feel any different, I don't care if the speed test shows a slightly lower ping or higher throughput.)
[Samsung Galaxy Nexus] osm0sis:
Also, it's impossible for a radio to cripple wifi since the wifi driver is in the kernel.
[Samsung Galaxy Nexus] gtwannabe:
It shouldn't, but flashing that radio definitely messed up my WIFI. Rebooted the phone, no change. Also had weird issue with WIFI status icon not showing up after toggling the WIFI on/off. Flashed XXLF1 and WIFI is nice and fast again with no quirks.
[Samsung Galaxy Nexus] WoodroweBones:
What ROM are you using and which kernel if you arent using the stock/included one?

As others have said the Wifi driver and Radios are completely separate entities so something is screwy there
[Samsung Galaxy Nexus] mr mystery:
You're alone there. This radio works great for me, holds signal longer in weak areas and coming out of the TTC subway finds signal again MUCH faster, almost instant fast. Whatever issues you are having with WiFi have nothing to do with this radio.
[Samsung Galaxy Nexus] gtwannabe:
Bone stock 4.1.1 (rooted)

It felt like it was latching onto the 3G and not cutting over to WIFI properly.
[Samsung Galaxy Nexus] osm0sis:
Stock kernel has crap Wifi drivers since JB. Try Franco r248, he merged all sorts of wifi fixes. Also uncheck "avoid poor connections" under Advanced.
[Samsung Galaxy Nexus] Psykologikal:
Anyone tried this for galaxysmtd? Galaxy i9100. I'm gonna extract modem.bin and test when I get home.

Sent from my time waster
[Samsung Galaxy Nexus] WoodroweBones:
Just to equate this to something real world it would be similar to saying "I put new tires on my car and now my electric locks dont work". Obviously it wasnt the tires but if someone hit a cable while putting them on that might have been the cause.

Probably not a great example but should make the point
[Samsung Galaxy Nexus] gtwannabe:
WIFI is crap in general... phone only sees certain 5ghz channels and often gets stuck in "connecting" loops. 2.4ghz works better than any of my previous Androids though.

---------- Post added at 04:27 PM ---------- Previous post was at 04:20 PM ----------

If the radio is bugged and not releasing the 3G data connection properly, yes, it can affect WIFI.

Again, the only variable was the radio flash.
[Samsung Galaxy Nexus] WoodroweBones:
I'm saying its an issue specific to you. The radio is fine but there is something else causing the issue on your phone. Not one other person has had an issue like yours
[Samsung Galaxy Nexus] matthewr87:
Hello everyone, I just have a few questions. I have a GNex from Telus that I flashed to yakju 4.1.1 several months ago. Can I flash this new radio on Yakju 4.1.1 without flashing the RIL? Will there be any negative consequences? If I need to flash the RIL can I do that without rooting? Thanks!
[Samsung Galaxy Nexus] efrant:
Yes.

No.

Yes (if you use the package provided). No (if you use GetRIL).
[Samsung Galaxy Nexus] matthewr87:
Okay thanks. To flash the radio I should just follow the same instructions in your thread (to flash yakju) but obviously only flash the new baseband?
[Samsung Galaxy Nexus] efrant:
Either:

1) Boot your device into fastboot mode and plug into your PC, open a command prompt in the same directory as your fastboot.exe file and the radio image, and type: fastboot flash radio name-of-radio.img

Or

2) Reboot into CWM and flash the CWM-flashable version of the radio I posted.
[Samsung Galaxy Nexus] dirtygoldfish:
I flashed the new UGLH1 radio yesterday and got a LocationManagerService wakelock that completely prevented my phone from deep sleeping. Switched back to the previous radio and immediately my phone was able to deep sleep again.

Anyone else ever experienced this, and should I even try flashing the radio again? :p
[Samsung Galaxy Nexus] WoodroweBones:
Did you match the RIL as well? What radio did you come from? I've been running this radio for a while now and its been great
[Samsung Galaxy Nexus] housry23:
I'm a little confused on these GSM radios. I'm a newly converted GSM user with an unlocked GSM Galaxy Nexus. Service provider is Straight Talk with AT&T SIM. Location is southwest Ohio. Is this the right radio for me? I currently have XXLF1 on mine, which seems to be a European baseband. Just wondering if I would have better reception and/or speeds on this one. The one I currently used works good, but you know us phone addicts, we are always trying to have the latest and greatest and tweak everything to make our phones work better. Thanks in advance.
[Samsung Galaxy Nexus] brigon:
Did you flash cache and dalvik?

---------- Post added at 04:47 PM ---------- Previous post was at 04:46 PM ----------

Did you flash cache and dalvik?
[Samsung Galaxy Nexus] strumcat:
@housry23: Only way to tell is just flash the UGLH1 radio and RIL, and see if it seems to work better. You can always flash back to XXLF1 if it worked better for you. UGLH1 has been working much better for me. You can use the GetRIL app to make sure your radio and RIL match.
[Samsung Galaxy Nexus] WoodroweBones:
I think it really all boils down to trial and error. While some radios are called "European" or "North American" I dont think that rules them out of either area.

Flashing radios is easy and I HIGHLY suggest matching the RIL as well. If it doesnt work just flash the old radio back and no harm no foul. If you are rooted you can even use an app called GetRIL for matching the RIL which can flash right in the ROM without having to go through recovery
[Samsung Galaxy Nexus] dirtygoldfish:
I did wipe both cache and dalvik cache, and I had a matching RIL (checked through the GetRIL app). I've flashed a couple radios before this, including the XXLF1 one I was using before trying this one and this wakelock has never popped up. Weird.
[Samsung Galaxy Nexus] brigon:
You tried rebooting to clear the wakelock right?
[Samsung Galaxy Nexus] dirtygoldfish:
Yuuuup. I tried rebooting multiple times and fixed permissions. The only thing that ended up working was flashing back to a previous radio.
[Samsung Galaxy Nexus] efrant:
I would try it this way: flash the radio in fastboot, reboot bootloader, then reboot.
[Samsung Galaxy Nexus] dirtygoldfish:
I'll try this later tonight when I have access to my laptop. Thanks.
[Samsung Galaxy Nexus] speedyink:
Thank you for this! My phone is working much better in low signal areas. This is awesome for me because I live in a low signal area! I'm now able to hold my phone and use data on my couch! Before I had to set it down in certain spots in the house to get data to work.
[Samsung Galaxy Nexus] jz687:
This is probably a dumb question (sorry in advance), but is it possible to flash a radio - and potentially flash back to the previous radio - without wiping the device?

If so, are there any easy-to-follow step by step radio-specific flashing guides?
[Samsung Galaxy Nexus] efrant:
Yes. Flashing the radio does not wipe anything.

You either download the CWM-flashable package, reboot into CWM and flash the zip, OR, you download the image, plug your phone into your PC in bootloader mode, and type this into a command prompt: fastboot flash radio name-of-radio.img
[Samsung Galaxy Nexus] jz687:
Thanks!!

I think I found a youtube tutorial that goes through the steps for the first option...

Kinda nervous to do it/screw something up... Also, another stupid question: how do I get the .zip file on the phone!?
[Samsung Galaxy Nexus] efrant:
How about just clicking on the link either in a browser on you phone or in the xda app? ;)

Edit: I just watched part of it. He says some things that are wrong. KK does not mean 2011, and the 6 is not the month. If we look at UGLH1:

UG = Canada

L = 12th letter of alphabet, representing 2012

H = 8th letter of alphabet, representing August

1 = first release in that month.
[Samsung Galaxy Nexus] jz687:
Hahaha, that works... Ok, gonna give this a go once I build up the courage.

Tried this radio in Norway, not better or worse than the first jb gsm radio here.

Sent from my Galaxy Nexus
[Samsung Galaxy Nexus] achan68:
I'm glad to hear that. I'm from Toronto Canada, and flashed this radio which seems to be working better for me. But I'm going to be in Finland and Norway towards the end of this month, and was hoping it works not perform worse in EU countries
[Samsung Galaxy Nexus] Damien White:
Got on with it!

If yer having doubts, just flash this radio. Really. It's not like flashing a Radio can brick yer phone. Just flash it and see how amazing it is, and if yer not sure if it will brick your phone just know, that it is just as easy to reflash the stock radio back.

Everyone gets nervous the 1st few times, get over it and start using your phone like the power house of a DROID it was meant to be...HOO HAAA!!!

Send from a small whole on the north side of Canada where PDAs like my GNex are more powerful then the average computer.
[Samsung Galaxy Nexus] jz687:
Decided to try and flash the radio.

So, I held down all the buttons and got to the part where I choose "recovery mode" and click the power button to choose it...

And I get a picture of the green android dude with a red exclamation/danger sign.

Right out of the gate and already a problem... ugh.

That was scary... Any idea why that happened?
[Samsung Galaxy Nexus] strumcat:
Completely normal. The horizontal android with the red exclamation point means that you successfully reached the stock recovery mode that comes with your phone by default.
[Samsung Galaxy Nexus] efrant:
As strumcat said, that is normal. What you are seeking is the main screen of the stock recovery.

You cannot flash a radio with the stock recovery - - you need to use a custom recovery. But in order to get a custom recovery, you need to use a computer to get it onto your phone.

Let me know and I can try to guide you through it.
[Samsung Galaxy Nexus] UltraBoykj:
Installed this Radio + RIL last night.

Working fine. It is certainly no worse than uglc1. Not seeing any real improvements.

I have noticed that my bars say 3g now instead of "H".

It is cool to have the "latest & greatest" though - thank you for the work to make it possible.

[Samsung Galaxy Nexus] msavic6:
The screenshot mobile syrup posted showed the same radio. Anyway with the stock yakju radio I feel as if I'm getting worse signal then before in my concrete school which to begin with has bad signal but now its gotten fairly worse. I guess I'm going to try to flash this radio and try it.
[Samsung Galaxy Nexus] cmstlist:
Would also be interested in finding the update.zip now that it's rolling out.
[Samsung Galaxy Nexus] Nukedathlonman:
Me three...I know my sister just received the OTA update to Jelly Bean this morning, but I can't check out the phone in person (we both have the same Gnex and are on Bell's network). I'm a bit worried because I had unlocked the boot loader and updated to the unoffical YAKJUXX 4.0.4 ROM then relocked it a good while back (when the ROM appeared in this post http://xdaforums.com/showthread.php?t=1419170). Currently my GNex is reporting it's fully up to date...

[Samsung Galaxy Nexus] angel.a:
Radio comparison chart?

Is there any chart comparing peoples experience with different radios on various networks?

A public spreadsheet might be useful for this, perhaps with columns Radio/Network/Comments.
[Samsung Galaxy Nexus] stevemw:
The slow updates aren't Google's fault. After an update is ready for release it has to be presented to the carriers with subsidized variants for testing and "enhancements" (bloating) before it can be pushed to those devices -- that's why the GSM version will always be updated first.

Heck, I bought a GNex HSPA+ because I'm tired of waiting for my Atrix *4G to get ICS.

[Samsung Galaxy Nexus] wallyg8r:
My radio got updated to UGLH1 but the bootloader remained at PRIMEKK15. I applied the ota to stock 4.0.2. Should the boot loader have changed?

fwiw:

This yakjuux 4.1.1 build seems smoother/quicker overall than the yakju 4.1.1 build.

Also chrome is stock and NFC/android beam are selectable in the settings (can't remember if they were in the yakju build).
