Stock ROM is built from AOSP...
[Samsung Galaxy Nexus] efrant:
Try building a stock ROM from AOSP and have it update when the OTA updates roll out.
[Samsung Galaxy Nexus] blunden:
Why did you thank him? :P

No worries. :)

EDIT: Nevermind, I was blind. :)

I would imagine the potential problem would be that registering as a listener for these "secret codes" would require the app to be signed with the platform key. That would not be possible on a stock rom.
[Samsung Galaxy Nexus] efrant:
He thanked me because I answered his question here... :)

That's what I was kinda figuring. Oh well.
[Samsung Galaxy Nexus] blunden:
Makes sense. I somehow thought he had quoted your post where you quoted me but actually reading it shows that wasn't the case. :)

Hmm, it might be specific to other Samsung devices like the SGS2. Didn't see that at first.
[Samsung Galaxy Nexus] ygvuhb:
i am not talking about galaxy nexus i9250

it is japanese sc-04d, the offical tech have not 900mhz

although everyone said they got same hardware

but still have not prove that is support 3g 900mhz unless we force it receive 900mhz to check

if it get same hardware it should change to reveive 900mhz after flashed other radio

or google radio setting is not the same as samsung?

just keep perfer stay in higher freg band?!

---------- Post added at 12:49 AM ---------- Previous post was at 12:44 AM ----------

that's interesting

the last hope for check sc-04d have 3g 900mhz or not

thanks all:)
[Samsung Galaxy Nexus] RogerPodacter:
Correct. To test, try covering the antenna to block all 2100 signal too see if it forces the phone to switch to the stronger 900 band. At least then you have a starting point.
[Samsung Galaxy Nexus] cmstlist:
You could also use an app such as Netmonitor to check the cell tower ID. Using a phone that *does* have a band selection menu (e.g. a non-Nexus Samsung or an LG), restrict it to UMTS 900. Now try going on a tour of places where 2100 signal is weak, and see if at any point in time the cell ID on the Galaxy Nexus matches the one on your other phone.
[Samsung Galaxy Nexus] ygvuhb:
cell tower id?

is that LAC CID & RNC? 2100 & 900 willl get different id?

I have a galaxy s2 I will test tmr

actually i pretty sure my sc-04d cannot receive 3g 900mhz

as 2100 only get week signal in my office when i near the windows, already tested in my gs2

if go away the windows my gs2 only can connect internet when use 3g 900mhz
[Samsung Galaxy Nexus] ygvuhb:
i tested the tower id at home, my gs2 also prefer use 900mhz, but 2100 also work well at home

at my office the 2100 is terrible:mad:

here is my SC-04D japanses galaxy nexus, flashed KK6 radio

and then GS2 force at 2100 only, got some id as same as galaxy nexus

and GS2 force to 900 only, none of id galaxy nexus can detect

:(
[Samsung Galaxy Nexus] cmstlist:
Interesting. And have you tried flashing any different radios to the SC-04D? Such as any radio that has shipped with the European version?
[Samsung Galaxy Nexus] ygvuhb:
yes I tried KK6 & KL1 which is European baseband

hope can find some app to force 900mhz, if it still have not 3g 900mhz,

SC-04D have different hardware:(
[Samsung Galaxy Nexus] bigboss875:
:confused: i am confused now what is the best radio
[Samsung Galaxy Nexus] The Gingerbread Man:
there is no singular best radio only which works best for you. Try them out to see
[Samsung Galaxy Nexus] Smallsmx3:
On T-Mobile in the SW USA. Anyone else? If so what radio seems to work best for u? On ugla4 for now. So far so good in Orlando FL. Just curious....
[Samsung Galaxy Nexus] RogerPodacter:
That is very strange. Ideally you should be able to force the nexus to jump to 900mhz by covering the antenna with your hand until all 2100 signal is lost and the phone seeks the stronger 900 band.

I know we had this issue with ATT in the past with 850 and 1900mhz. ATT network forces the phone to camp on the weaker 1900 freq even when there is little signal, while full bars of 850mhz is available in the same location. You could block the antenna forcing the phone to switch to the stronger freq. But it eventually switches back to weak freq.
[Samsung Galaxy Nexus] The Gingerbread Man:
Perhaps this weird radio behaviour is maybe why its taking a while to get these problems sorted before OTA start again? My 3g dropping gets annoying at times and wifi can be buggy at times so hopefully the Google devs are looking at these issues, I'm sure they know they exist
[Samsung Galaxy Nexus] ygvuhb:
this assumption is base on i9250 & sc-04d have the same hardware

if they got differ 3g chip, sc-04d without 900mhz, that make sense(my gs2 can auto change to 900mhz , using same network & sim card)

i will test again at my office today , got very week 2100:(

update: good news

i tested at my office sc-04d nexus got a same id as gs2 force to 900 mhz

i will post prove after back home

thanks all

is that have any way to edit the radio file only receive 900mhz?

so i can flash the 900mhz radio when i am at office

flash back when i leave

or can us build a app to force the radio receive specific band in nexus?
[Samsung Galaxy Nexus] gbalerdi:
Hi,

Anybody knows the difference between an Euro radio (XX) and a North American one (UG) ??

(I've noticed that it **seems** that the same version even exists in the two flavors ... like UGKL1 and XXKL1 )

Of course I understand that the exact differences are not known, but I wonder if there's any typical / obvious difference , like preferred or default bands, etc, that everybody knows about and I don't.

(like when I had the Captivate I remember reading that certain radios defaulted at 850 Mhz, if I remember correctly)

Thank you very much

Gonzalo
[Samsung Galaxy Nexus] efrant:
Wonder if it would be possible/realistic to disassemble the radios using something like IDA Pro?
[Samsung Galaxy Nexus] ygvuhb:
that is my testing for japanese galaxy nexus SC-04D receive 900mhz(use Netmonitor)

use radio kk6/KL1 European radio (same result) (the SC-04D radio is not work on 900mhz, only support 800/1900/2100)

first day i only have my SC-04D

check netmonitor

only have four tower id received at my office

i discover when the phone connected id "25444" , get a good internet connection,

"20443" also have connection but very slow speed

the other two cannot connect to internet

2nd day i bring my gs2 and SC-04D back to office

i force the gs2 to receive 2100 by services mode, the signal is very bad, only got 0-1 signal bar

got three id as same as galaxy nexus

and then gs2 force to 900mhz, got much better signal

keep three or full signal bar

and it only show "25444"

so the id "25444" is 900mhz

as SC-04D also receive this id, finally can prove that the SC-04D have 900mhz although the official tech on SC-04Donly mention 3g 800/2100

but when SC-04D connected id "25444" 900mhz, the signal bar only got 0-2 (internet connection is ok)

seem the SC-04D have a weaker connection in 900mhz

thanks efrant tell me , use Netmonitor to check the id

so i can wait the phone change to "25444", and i sure i can connect internet (not everytime can connect "25444", seem the setting is highly prefer use 2100 although it is very very weak)
[Samsung Galaxy Nexus] efrant:
I think we were all expecting this, given that there are only 2 hardware version: maguro and toro.
[Samsung Galaxy Nexus] RogerPodacter:
Well that proves the nexus does support 900mhz. And the specs confirm that:

http://m.gsmarena.com/samsung_galaxy_nexus-4219.php

Too bad there is no way to force 900mhz.
[Samsung Galaxy Nexus] ygvuhb:
the official samsung jp, only mention 800/2100

it is so confuse

http://www.samsung.com/jp/consumer/mobilephone/mobilephone/docomo/SGH-N044TSNDCM-spec

---------- Post added at 05:08 PM ---------- Previous post was at 04:57 PM ----------

do we have any way to force the phone receive 900mhz

wait the phone change to receive 900mhz is so stupid as the setting is highly prefer 2100:eek:

is it possible to edit the radio only receive 900mhz:mad: (like official SC-04D radio setting only support 800/2100)
[Samsung Galaxy Nexus] RogerPodacter:
Ok now i see why i was confused. You bought the japanese version. Theoretically it is supposed to be identical to the world version, but now we know that for sure i guess. Even though samsung doesnt list the official specs for the japanese version with all freq.

Either way there is no way to force a freq that i'm aware of.
[Samsung Galaxy Nexus] dave_speed:
Is an updated radio includet in the offical OTA update ? http://android.clients.google.com/p....signed-yakju-IMM76D-from-ICL53F.7f97fbc1.zip

The radio.img.p is only a half MB .. or is this a diff and we have to wait until somebody flashes OTA over Stock image and extracts the radio ?
[Samsung Galaxy Nexus] efrant:
I may be possible if someone wants to attempt to disassemble one of the radio images...
[Samsung Galaxy Nexus] josteink:
That's not trivial. The radio chips may be running on custom PLGAs, custom ASICs, unkown combinations of known radio chips and micro-controllers.

There is no guarantee we even know how the instruction-set is on these images. I'm pretty sure they are not your regular ARM assembly and IDA Pro wont get you anywhere on these.

If these could be programmed/dissembled as easily as the rest of the components on our phone, I'm sure the OSS fanatics would have had a go at them a long time ago, nasty binary blobs as they are.

Not saying it can't be done, but lets not get ahead of ourselves here ;)

(PS: If it could be done, the only next logical thing, a Radio-kitchen, would be super cool :) )
[Samsung Galaxy Nexus] zephiK:
Yes a updated radio is included (XXLA2). I've been asking users who have flashed the radio to upload the dumped radio for us.

I'll upload it and make a flashable zip when someone does it for me... or they can make it into a flashable zip if they know how.
[Samsung Galaxy Nexus] josteink:
Yup. You need to be on stock for this to work. Unless someone figures out how we can binary patch the radios with the img.p file in that update without going all the way back.

I'll be lazy and wait around :p
[Samsung Galaxy Nexus] RogerPodacter:
Not only that, but its my understanding that a verification key or checksum is verified on the radio, and this fails if any of the radio contents are changed which is why we've never seen custom radio images.
[Samsung Galaxy Nexus] efrant:
Here is the new radio from the yakju 4.0.4 update, both in fastboot format (extract the zip) and CWM format. I haven't tested them out, but they should work fine.
[Samsung Galaxy Nexus] zephiK:
Works perfect. Flashed via fastboot.

A new bootloader is also available (PRIMELA3), although this was posted last month in a leak.

MD5 for radio-maguro-i9250xxla2.zip ~ FEF1599B79E7F56FCC592AC885EBBEAA
[Samsung Galaxy Nexus] efrant:
I have no doubt that it would be quite the daunting task! :)

The reason I mentioned it is because someone managed to disassemble the bootloader on the Nexus One, which gave us custom bootloaders (with the ability to change partition sizes, etc.). I don't know if there would be a difference between that and a radio, but I would image they would both be difficult.

I'll post the link to the Nexus One disassembled bootloader once I find it.

[Samsung Galaxy Nexus] dave_speed:
XXLA2 or XXLA4 ?
[Samsung Galaxy Nexus] Sdobron:
So is the OTA radio XXLA2 or XXLA4?

I see two conflicting posts.

I'm running UGLA4 and have no issues on T-Mobile US
[Samsung Galaxy Nexus] zephiK:
There is no such thing as XXLA4. It's UGLA4 and XXLA2. That person most likely typed it wrong. Wouldn't make sense if XXLA4 came out and the OTA for yesterday provided radio of XXLA2.
[Samsung Galaxy Nexus] sluflyer06:
UGLA4

Running 4.0.4 based ROM this radio prevented me from maintaining a connection to Google's servers, things like calender,gmail, etc had to be synced manually. Back to UGKL1
[Samsung Galaxy Nexus] Sdobron:
I don't think that was the radio. Rock solid here.
[Samsung Galaxy Nexus] efrant:
Yeah, this can be done. All it takes is just some editing of the updater-script file. It would have to be specific to each radio though. Much faster to let someone already on the build update OTA and dump the radio.
[Samsung Galaxy Nexus] josteink:
Awesome. Added mirror and added to first page. Trying it now :)

Will test XXLA2 for a few days, but if no change I'll be reverting back.
[Samsung Galaxy Nexus] ygvuhb:

[Samsung Galaxy Nexus] efrant:
The bootloader will not flash a radio (via fastboot) that is corrupt, so for the fastboot image, it makes no difference.
[Samsung Galaxy Nexus] :
well, i prefer using the recovery, since i won't have to tether the phone to my a computer.

and checksums are always nice to be sure that the download isn't corrupted. i prefer downloading it onto the phone and then making sure that the download is fine. saves me from re-booting...
[Samsung Galaxy Nexus] cocchiararo:

Not as much as you would think. I've used both XX and UG radios, and haven't noticed much of a difference between them.
[Samsung Galaxy Nexus] nikulogical:
Same. But we haven't experienced regional issues. Some Fido, wind, and mobilicity customers were facing roaming issue which only the NA radios fixed.
[Samsung Galaxy Nexus] bewA:
I just thought i'd share i've been using UGLA4 on my GN on Three and i've been pretty impressed! I would say an extra meg down and maybe half meg to a meg up!

hardly scientific but still i'm pretty happy! Although i think latency seems a bit higher.

I've not done any stuff on the battery life side as i don't care much for that!

XXKK1 is known to have signal drops when using 4.0.2+
[Samsung Galaxy Nexus] !crazy:
Xxkl1 > xxkl2

I flashed google factory 4.0.4 image yesterday, so I got XXLA2 with it. It didn't work well, I was getting singal drops, and lower signal in general then with XXKL1 and 4.0.3 roms. I have then flashed XXKL1 to see how it works with google's 4.0.4 and it is great. Much better signal!
[Samsung Galaxy Nexus] 3r0k:
Currently I am on XXKK6, which is a Standard European Baseband, could anyone point me in the direction for the Best T-Mobile USA radio? Any suggestions would be greatly appreciated.

EDIT: also on 4.0.4, still getting used to my GNex...
[Samsung Galaxy Nexus] zephiK:
just because 1 radio is good for one person doesn't mean it will give you the same result. try the newest ones and find one that you like and keep it.

XXLA2 is the newest followed by UGLA4.

XX = Europe

UG = North America

... but it doesn't matter, just flash them and see which one works better. if those don't satisfy you, go flash the older ones.
[Samsung Galaxy Nexus] krex:
Sorry, 2 questions.. Does google factory 4.0.4 image come with XXLA2, doesn't it? Do you have yakju originally?
[Samsung Galaxy Nexus] !crazy:
Yes and yes : ). But not sure I understand the 2nd question completely...
[Samsung Galaxy Nexus] krex:
There is a lot of people had some yakju Samsung region variant (eg: yakjuwx, yakjuzs..) before they moved to Google supported yakju factory image. They have signal issues now with 4.0.4.

Since you wrote you got the factory image with XXKL2 (which doesn't come with this but XXLA2), I was wondering how and where you downloaded 4.0.4 with XXKL2... ..and I thought you have some yakju variant..
[Samsung Galaxy Nexus] !crazy:
Hi, thanks and sorry. It was my bad, I got it with XXLA2, not XXKL2. XXLA2 didn't work well for me.

In my opinion XXKL1 is a massive improvement over XXKK6, which in my experience performs roughly the same as XXKK1.

Others have reported that they get radio-crashes/signal-issues with XXKL1, while others have attributed this to their 4.0.3-build as opposed to the actual radio.

YMMV. I recommend trying XXKL1.
