Team,

I am from INDIA. I see my friends S2 switches to H+ and is getting speeds upto 6Mbps at the same location. While my Galaxy Nexus is stuck at 3 Mbps.

Speed test app was used.

My baseband is I9250XXLF1.

What should be solution ?
[Samsung Galaxy Nexus] a5pe4:
So I flashed bigxies 4.2 ROM and I see that I still have my UGLH1 radio. Does this mean I have to manually flash the radio and also can I use twrp to flash it or is cwm the only choice? I'd prefer not to use fastboot.
[Samsung Galaxy Nexus] DualDark:
How do I choose or how do I know which is the best baseband to use on my phone? I'm from Mexico.

Btw, what's makes difference between one baseband and another? If I'm not using the correct for my country will I have bad reception or maybe unnecessary battery drain?

Thanks in advance and sorry for such noob questions.

I see, so if i change the kernel, i could get better wifi reception? Right now im on stock 4.2, and its running so smooth, but im willing to go back to 4.1.2 if it means that it will get better.
[Samsung Galaxy Nexus] osm0sis:
Downgrading your kernel would be a terrible idea, and probably wouldn't work anyway (ie. cause boot loops) considering how different these last kernel versions are. Custom kernels are an option however. First though, go into Wi-Fi and advanced options and make sure you disable "avoid poor connections" and the new powersaving option. Both should improve your connection/stability. Give that a shot.
[Samsung Galaxy Nexus] gwindlord:
Is UGLH1 better than XXLF1 for 4.1.2 at Eastern Europe?.. My personal experience is that UGLH1 has slightly louder sound in ear speaker and +10 - +15 dBm for signal, but I hesitate about battery life a bit, could anyone please share opinions/experiences?..
[Samsung Galaxy Nexus] osm0sis:
Sound? Radio also has nothing to do with sound.
[Samsung Galaxy Nexus] Kocai:
I think he meant in call volume when receiving calls. From my experience in flashing radio for my SGS, different radio/baseband can have lower/better quality in in call volume. But then again, the network quality of one's carrier has much more impact than the radio itself.
[Samsung Galaxy Nexus] zephiK:
Not a fan of the new radio, takes way too long to lock on.
[Samsung Galaxy Nexus] gwindlord:
Yeah, I mean the call volume seems to be a bit better and a signal is a bit better too. I mean radio is that part in the whole bunch of call influencing factors, that we can change, and I've just wanted to ensure. The only item I hesitate is radio battery usage: recently I've noticed phone/radio taking noticeable percents, sometimes it looks even that radio eats something even in airplane mode, dunno why. So looking forward for someone's experience at UGLH1 vs. XXLF1...
[Samsung Galaxy Nexus] Kocai:
I'm confused; what do you mean by "radio eats something even in airplane mode?" You should try and install BetterBatteryStats to know for sure what's draining your battery.
[Samsung Galaxy Nexus] gwindlord:
I'd not believe in that also, but GSam shown radio drain percent increasing while night sleeping at airplane mode couple of times. But BBS does not show anything abnormal, this is the reason of my asking here :)
[Samsung Galaxy Nexus] boki2911:
whether it can install a new radio XXLH1, on Maguro gms 4.1.2 yakju

and that the installation will delete all or not
[Samsung Galaxy Nexus] bartolinio:
you can

nothing will be deleted
[Samsung Galaxy Nexus] boki2911:

dB Signal - A basic guide

-50 (perfect, standing next to the tower)

-60 to -70 (extremely good, rare)

-80 to -85 (normal downtown)

-90 to -95 (getting on the weak side)

-95 to -98 (weak, dropping calls)

-98 to -100 (bad, hard to stay connected)

-100+ (basically no usable signal)
[Samsung Galaxy Nexus] The Gingerbread Man:
So how do the signal bars come into play with this? I'm at -95 but 1 bar off full

Sent from my Galaxy Nexus
[Samsung Galaxy Nexus] osm0sis:
I've always wondered about that too. I'm at -107 but 1 bar off full, signal showing as between the dark and the brighter yellows under the Battery settings graph page. Reception and connection for call, text and data is fine in practice. I'd say maybe wbknox's guide could be valid in his area but is definitely not universal.
[Samsung Galaxy Nexus] The Gingerbread Man:
Here's my battery stats, as you can see when I got home i turned on my WiFi and my signal goes grey and before I was using 3g network, I can't say I often take the time to look at the dB reading but my signal bars almost always show full or nearly full

Sent from my Galaxy Nexus
[Samsung Galaxy Nexus] osm0sis:
Okay now I'm at -111 and have no bars, so it must be some funky algorithm they use for it. I sure can't figure it out.
[Samsung Galaxy Nexus] CMNein:
I've always been lucky, rare for me to have less than -80.
[Samsung Galaxy Nexus] anil76:
I am facing occasional auto dis-connection of WiFi and Bluetooth after 4.2 upgrade. It disconnects and reconnects within a min. on its own. Could this be due to new radio that came with 4.2 ? Any advise on preferred radio to be used in India. Stock radio with 4.1.1 worked fine for me ? Can I just flash that on 4.2 image ?

I m using takju build on my Gnex .
[Samsung Galaxy Nexus] Pkt_Lnt:
Wifi and bluetooth are controlled by kernel and modules, not radio. You could try a custom kernel, or do what many have found to be best, go back to 4.1.x.
[Samsung Galaxy Nexus] osm0sis:
And make sure "avoid poor connections" is disabled in advanced WiFi settings.
[Samsung Galaxy Nexus] gwindlord:
Anyway, what would you recommend for Eastern Europe on 4.1.2, UGLH1 or XXLF1, and which are pros/cons?..
[Samsung Galaxy Nexus] osm0sis:
I'd try XXLH1 first if you haven't before, since it's the newest radio and XX is technically for Europa where UG is for Canada/North Am. Then I'd try XXLF1 and then UGLH1 for comparison.
[Samsung Galaxy Nexus] gwindlord:
Thank you, and should I flash RIL for each radio, or leave CM10 one?..
[Samsung Galaxy Nexus] osm0sis:
I'd use the JOP40C RIL that XXLH1 came with. Odds are both of the LH radios will benefit from it, and LF might too.
[Samsung Galaxy Nexus] anil76:
I had disabled it along with a new WiFi optimization setting also but still face this issue.
[Samsung Galaxy Nexus] osm0sis:
I might be wrong but I feel the wifi optimization actually keeps the radio at lower power. ie. saves other power when wifi is active/connected. Either way wifi is a kernel thing, not radio.
[Samsung Galaxy Nexus] Spitfire:
Do the flashable radios have RILs with them, or is that separate? Can I just flash different radios through twrp to see which give me the best signal? The current one I have is xxlf1. If I flash another and don't like the result, would I be able to simply flash the xxlf1 again and get back to normal? Just making sure I don't complicate things or assume they are too simple.
[Samsung Galaxy Nexus] technogravy:
I'm getting unusually high battery consumption on the phone app after switching to 4.2 and lh1 radio, this is on both OTA or AOSP. This never happened before upgrading.

Is this radio related?
[Samsung Galaxy Nexus] efrant:
No it will not.
[Samsung Galaxy Nexus] josteink:
Unlocking the bootloader is what factory resets the phone. Once you have done that, your phone wont get wiped/factory reset via fastboot, unless you tell fastboot to do so.

So yeah, you should be safe.
[Samsung Galaxy Nexus] jalkamal108:
Thanks soo much for prompt reply. I will try flashing it and let you guys know the speed results between i9250UGLA4 and old I9250UGKL1
[Samsung Galaxy Nexus] motopig:
MD5 for UGLA4 fastboot image please.

My download returned 444f902cb96cec71fd87e900a2add077

I am with Mobilicity so this radio should help.
[Samsung Galaxy Nexus] wiki_warren:
It will NOT factory reset if your booloader is unlocked.
[Samsung Galaxy Nexus] efrant:
That MD5 hash is correct.

By the way, fastboot will not flash a corrupt or unsigned radio image to your device. It will fail.
[Samsung Galaxy Nexus] 90miles:
Testing new baseband on Videotron.

So far so good

I'll keep update
[Samsung Galaxy Nexus] GrandMstrBud:
I was on the XXKK6 radio and it would always revert to GSM/CDMA auto (PRL) so I flashed to the UGLA4 and now I have no service. Is there an easy way to flash back? I'm on a T-Mobile network.

EDIT: Never mind it just took it a little bit. WCDMA preferred will still not stick though.
[Samsung Galaxy Nexus] :
None of the options ever stick for me, I'm just going on the hopes that it has stuck but just doesn't display that way.. I think this is what happens for most people?

Dan
[Samsung Galaxy Nexus] josteink:
No fancy speedtest.net diagrams. Just saying that UGLA4 really didn't seem to perform very well in downtown Oslo Norway. Reverted to Docomo for now.
[Samsung Galaxy Nexus] mralexsays:
I've been using this for a full day now and (on AT&T in Atlanta,) my speeds seem to be roughly the same and I seem to be getting slightly better reception (lets say maybe about 1/4 of a bar.) This is just in my unscientific testing, but overall this radio (UGLA4) seems to be a very slight improvement over UGKK1 and UGKL1 for me.
[Samsung Galaxy Nexus] The Gingerbread Man:
OK I am an idiot, really need some help. Firstly I take full responsibility and shouldn't of messed with something I don't understand.

That hidden menu in the OP *#*#4636#*#* I went into it and phone information and did something and for the life of me I don't remember which one of the buttons I pressed or how each of them is set by default cos if pressed each more times than I remember.

My issue is I can't send any SMS anymore, I was hoping someone could tell me how the buttons are supposed to be by default or post a screen shot to show me. Heres mine
[Samsung Galaxy Nexus] efrant:
Or you could do it yourself: http://wiki.cyanogenmod.com/wiki/SMSC_Updates
[Samsung Galaxy Nexus] The Gingerbread Man:
Yeah got it sorted now, thanks again. There were quite a few message center numbers for orange UK around and had to set it using an old Nokia as it didn't want to work using my nexus
[Samsung Galaxy Nexus] motopig:
Great. I flashed it and it went through...

... Since I'm on a HSPA-only network I have always set mine to WCDMA only, and it sticked across the flash. Canadian unit flashed yakju 4.0.2.
[Samsung Galaxy Nexus] G2_Gordon_G1:
Coming from a newb who is just trying to keep his phone well updated...THANK YOU VERY MUCH!!:D
[Samsung Galaxy Nexus] cmstlist:
I find the options only stick (for a while) if you're already able to connect to the appropriate type of network when you choose it. So if I am stuck on GSM and I select WCDMA only, it'll revert. But if I convince it to connect to HSPA, then WCDMA only will stick.
[Samsung Galaxy Nexus] GrandMstrBud:
I'm hoping but I know on all other android phones that I've had (Nexus One, Nexus S, Sensation) they were set to WCDMA preferred by default. I've had a couple times when going from a 3G area to EDGE it kept the 3G signal and when trying to make a call is said mobile network not available so I flipped airplane mode on and off and it kicked back onto EDGE with a signal. That was on the prior radio now so we'll see if this new one helps.

---------- Post added at 10:29 AM ---------- Previous post was at 10:26 AM ----------

Same here WCDMA only will stick but on a reboot it reverts back to GSM/CDMA auto (PRL). I don't believe this did this on the other Nexus phones.
[Samsung Galaxy Nexus] Leandros_Ger:
nothing :D
[Samsung Galaxy Nexus] haxor:
As I flash latest radio XXLHI for 4.2 so I have to flash boot loader too ?
[Samsung Galaxy Nexus] bartolinio:
definitely not
[Samsung Galaxy Nexus] IAmReflex:
Just flash the radio.

Did someone make a mistake I downloaded the ril file twice and every time I get md5 6e862cb777770d8277d2e0261e175120
[Samsung Galaxy Nexus] osm0sis:
I'll check it out this evening when I'm home but that was definitely the md5 I got after flashing the OTA.
[Samsung Galaxy Nexus] efrant:
No mistake.

6e862cb777770d8277d2e0261e175120 is the md5 of the zip file.

2a8ca6aaa7f169d5d13db6a636e4df19 is the md5 of the RIL.
[Samsung Galaxy Nexus] killbill234:
can i flash 4.2 radio while im on 4.1.2 ?
[Samsung Galaxy Nexus] Mayday_XL:
Yes you can.
[Samsung Galaxy Nexus] majinkenZERO:
Yes

Very pleased with the latest radio (XXLH1). I have T-Mobile and I work in North Dakota a lot (not a lot of love here from T-Mo) and everytime I was roaming I would only be able to roam on Edge. Now I can jump on AT&Ts 4G network. Again thanks and very pleased.
[Samsung Galaxy Nexus] L-ViZ:
Wanna flash latest radio from 4.2 as well. ril working correctly on 4.1.2?
[Samsung Galaxy Nexus] wbknox:
Android 4.2 update rolling out to yakju Galaxy Nexus, factory image available, can someone make new

RIL and radio flash CWM

[Samsung Galaxy Nexus] osm0sis:
Try it and let us know. ;)
[Samsung Galaxy Nexus] aamadorj:
XXLH1 radio and RIL from Android 4.2 are working fine on my GN with ParanoidAndroid 2.54, based on Android 4.1.2. As far as I know, radio and RIL aren't ROM dependent.
[Samsung Galaxy Nexus] wbknox:
do i have to flash RIL after every cm update?
[Samsung Galaxy Nexus] osm0sis:
It is part of the ROM. So common sense says yes.
[Samsung Galaxy Nexus] shawnaye:
Yakju factory build doesn't bring along a different modem does it?
[Samsung Galaxy Nexus] chrone:
This is getting interesting.

Perhaps when our radio signal from the tower is reaching -90db and downward (-100db or even less), our phone needs to amplify its signal using own battery juice just in order to gain stable signal coverage (near full bar), thus explains the hot area on the rear side and the battery drain. And when the signal is over -111, the phone gives up for power saving.

Sorry for the bad English and please correct me if i'm wrong. :p

Sent from my Galaxy Nexus
[Samsung Galaxy Nexus] wbknox:
If your on wifi you will get a different signal than when you are not.
[Samsung Galaxy Nexus] osm0sis:
Interesting thought, but the hot area isn't the radio, per se, it's the CPU/GPU (SoC). Heat can be reduced massively by undervolting these. I don't ever find the heat produced changes with coverage area, more to do with CPU/GPU usage. So you might be right in some respects, but the heat isn't really evidence one way or the other, I don't think. :)

Really no need to repost.. especially when it was just quoted and we were just talking about how inaccurate it is for us. Perhaps you'd like to edit your post and comment on that instead?

Thank you. :good: Correct, it displays different numbers because the radio is in low power mode with wifi when you're not on a call, but that doesn't change the fact that my phone doesn't become "unusable" below -100 dB. Call clarity, stability and data all work fine, so my criticism still stands: though it may be correct in your area, your guide is not universal. :)
[Samsung Galaxy Nexus] chrone:
Yeah, i might be wrong. :D

My thought was based on my last local gsm operator, though the signal status bar always full, the db reading on settings > about was always in the range of -90 to -100db, i noticed the phone heated up often though it just only sit there in my pocket at the office. Changing better gsm operator with better db signal (-60 to -79db average), i never feel the heat again up until now. Hehe

Sent from my Galaxy Nexus
[Samsung Galaxy Nexus] wbknox:
you could be wright.
[Samsung Galaxy Nexus] osm0sis:
You could be partially right too. I guess in LTE phones the amplifier that creates the radio signal does get pretty hot. GSM just isn't as hot and I've only ever noticed it heat up during a call with my GSM Nexus. ;)
[Samsung Galaxy Nexus] Kocai:
It depends on the phone. My old Sony Ericsson T650 would easily heat up in low coverage areas. I believe it's because the phone keeps trying to search for better signal (don't know how to put this properly since my English is not very good) which is normal and expected behavior I guess. I'll try and do some test with my Nexus when I have the time because there's a particular spot in my home that's like a black spot. Any phone, any carrier would never get higher signal than -105 dBm in that spot. What app would you recommend to monitor the temperature of phone?

By the way, if this is way off topic, please do say so and I won't post about this again.

Edit: osm0sis, congratulations on being a recognized contributor :)
[Samsung Galaxy Nexus] Pkt_Lnt:
Here is an article with answers. Close to tower, low phone amplifier power, lower battery consumption; far from tower, high phone amplifier power, higher battery consumption.

GetRIL uses a database to identify all the different RILs. If it hasn't been updated, it won't tell you anything of value.
[Samsung Galaxy Nexus] wbknox:
can you make me a RIL that i can flash base on RIL 6e862cb777770d8277d2e0261e175120 or yakju
[Samsung Galaxy Nexus] osm0sis:
What are you saying? yakju JOP40C has a different RIL than takju JOP40C?

Edit: Nevermind. You just don't understand at all. The MD5 listed is of the lib inside the zip not of the zip itself, like efrant just explained.

@efrant: Would you mind throwing a link to my RIL comparison post into your RIL page? http://xdaforums.com/showpost.php?p=33788079&postcount=1675 :) Won't help with all of these misunderstandings but could help some.

Thanks efrant, I sent a report/request to the GetRIL developper, will wait for him to reply/update then
[Samsung Galaxy Nexus] osm0sis:
No. The RIL MD5s I post (and as listed in GetRIL) are of the RIL libs themselves. yakju and takju have the same RIL and its MD5 matches the one I posted. Please read the responses to the posts you quote next time:

can i flash the cwm version over twrp??
[Samsung Galaxy Nexus] 5pace:
Yes sir.
[Samsung Galaxy Nexus] osm0sis:
Been trying out UGLH1 the last couple of days and it's excellent. Signal is improved like before, and so far no drops with the JOP40C RIL like there used to be on JRO03C.
[Samsung Galaxy Nexus] shawnaye:
Hmm so a change in ril helped with signal?
[Samsung Galaxy Nexus] osm0sis:
Nah helped with the drops I hope. The UG radios always have provided a bit better reception/signal strength in my area. 4-6 dB/~1 bar of difference according to Status and the Battery graph showing as dark yellow out at my house instead of grey. The RIL is basically the proprietary binary driver for the radio so I'm hoping that the occasional unrecoverable drops that were happening with UGLH1 on JRO03C and its accompanying RIL are fixed on JOP40C with its new RIL - so far so good! :)
[Samsung Galaxy Nexus] rolear8:
So there are you going to upload the radio for 4.2 north america? I checked and there is only the one for Europe.

Thanks partners.
[Samsung Galaxy Nexus] osm0sis:
There haven't been any regional OTAs to get them from yet.
[Samsung Galaxy Nexus] rolear8:
So do you think is a good idea to try that out even if I'm in America?

Thanks
[Samsung Galaxy Nexus] osm0sis:
Definitely. XX is "Europa" but it's also the international radio. Next best bet would be the recent UG radio. It's for North America and currently I'm having great results with it. Try each for a week and see how you feel.
[Samsung Galaxy Nexus] rolear8:
Well ive been con UGLH1 but thats from 4.1.1 so ibthink i will try the xx for 4.2
[Samsung Galaxy Nexus] osm0sis:
Doesn't matter what ROM it came with, radios are independent. It's still built at around the same time, since they're both LH1.

Anyway, definitely try the XXLH1. And in my observation so far, UGLH1 works better with 4.2 than it did with 4.1.1 or 4.1.2 and I'm attributing that to the newer RIL. ;)
[Samsung Galaxy Nexus] MoneyFist:
XXLF1 London UK

I haven't touched my radio, although I was tempted to upgrade it because I am a tinkerer.

Just before I was about to upgrade to XXLH1 when I saw that my time without signal was 0% in 26hours.

To me that's extremely impressive considering the amount of signal issues I've had with other phones in the past.

So I resist the urge to flash.

Location: London, UK

Radio: XXLF1 (Was default with the phone)
[Samsung Galaxy Nexus] ChazzMatt:
EXACTLY. Both radios were built in August 2012. When the radios were built by Google is a better indicator than when they were "released" in a ROM.
[Samsung Galaxy Nexus] rockingwing:
Hey there,

I'm currently on XXKL1 running AOKP JB Build 5 (Android 4.1.2) and plan to update my radio to XXLH1 (which is from the 4.2 OTA Update)

Will there be any conflicts due to it being from a newer Android version or can I use it without any problems?

Thanks in advance for any hints :)
[Samsung Galaxy Nexus] aamadorj:
My GN running ParanoidAndroid 2.54 (based on Android 4.1.2) is using XXLH1 radio without problems. So far, I think this radio is one of the best for my country. Don't forget to flash corresponding RIL, also.

By the way, according to many posts and my experience, radios are Android version independent.
[Samsung Galaxy Nexus] josteink:
Dont worry. You can usually mish mash radios and ROMs together as you like. Worst thing that can happen is that you are having stability issues and get signal dropping, which may happen if you flash a really old radio with a really new ROM. And in that case, just flash another radio.

Usually though, you wont suffer any issues no matter what you do. Mix ROM and radio as you like. And if you feel experimental, and this is clearly optional, you can try to do some RIL matching as well, although that is (like most radio-"science" ) strictly speaking not proven to always provide better results.

Happy flashing :)
[Samsung Galaxy Nexus] avelec:
I'm currently running [AOSPA 4.2.1] PARANOIDANDROID 2.99 betaFIVE rom. Do we need to update the new radio? Any advantage? Currently on XXLF1, with T-mo usa, I have the YAKJU version. Thanks in advance.

[Samsung Galaxy Nexus] Milamber:
Phone usually ignites into a fireball within 14hrs, sometimes 12hrs depending on the phone build.
[Samsung Galaxy Nexus] osm0sis:
I just want to add that the RIL is the same for JOP40D. I MD5'd and updated my posts as such the other day. :)

Also please change your links to point to my post and not directly to the attachments. Thanks and cheers. :good:
[Samsung Galaxy Nexus] ChazzMatt:
Done. One link was to the attachment, the others were to original posts for explanation and to give credit. :) Two of the three links were set for posts -- yours and efrant's. For the last link, I did have the download link for the RIL, as it was the 2nd reference to your excellent XXLH1 post. Since the first reference was the link for your post itself I didn't see the need to send people back to the entire post again. But, I've now changed it.

I've also updated my post to reflect your confirmation that the RIL is the same for JOP40C and JOP40D.

osm0sis, thanks for all the information you've provided. I was quoting your philosophy about the RILs, which seems to be correct. Between here and Franco's thread you are a real go-to asset. Thanks again.
[Samsung Galaxy Nexus] josteink:
You'll keep whatever RIL was included in your ROM and it will probably work just fine.

TWRP?

Hey can I use TWRP to load these radios? They say flash or CW bootable.

Probably a lame question, but I don't want to f things up loading the radio the wrong way.
