Hi, I'm using the european i9250 nexus. Which one is the best baseband, just the most recent? sorry for noobing around but I don't install nothing on my phone for a long time

The one that works best for anyone can only be determined by testing different ones that have been mentioned multiple times in this thread. Or unless someone here lives in the same town as you, works at the same place as you, and goes to all the same places as you, you will have to test yourself.

Ok youre right, thx for help me.

Rewrite my question:

Of the posted Basebands, which are the bests (2 o 3 that uve tested, sorry my english) for ATT network?

QUESTION

Hi friends,

For this model i9250, is the baseband really interchangeable via flash

Currently my phone is on band 1700/2100AWS .

If I travel, or change provider with (*) 850 / 900 / 1800 / 1900 or 850 / 1900 / 2100

Can I just choose a baseband with (*) and flash ? Does doing this will require a new RIL or nothing to worry ?

Will it actually work Well enough, considering the antenna (and transceiver hardware) is not the same ?

You can safely flash any baseband and it will work on any carrier with any frequency 850/1900/1700/2100/900 whatever.

However, some basebands may get better reception/performance with some frequencies/cell carriers than others but that is up to you to experiment and try.

For instance, most basebands I've tried work great with T-Mobile here in South Florida, USA but one baseband from Australia prevented my phone from picking up AWS 3G (1700 band)

That was the case for here, too. I'm on Wind in Canada which uses 1700 (or maybe 2100). I had been on XXLF1 but decided to try DVMK1. No connection. So I backtracked to the one that looked like it came with the next-newest version of Android (XXLJ1) and all was well.

Hey I am using Wind in GTA.
What speeds are you getting with downloads and uploads?
I see 3G and H+ sometimes.
I am using a different modem than you. I am using the one in the North America list UGLA4 and it seems to be working well.

How are you for signal and sound quality?

This is the thing that I wanted to be sure: OKAY to convert this phone from band 1700/2100AWS INTO the "more common" GSM/3G/4G (*) 850 / 900 / 1800 / 1900 or 850 / 1900 / 2100 ?

My recollection is: "typical" GSM/3G/4G phones from US, although they won't work in ASIA with slightly different frequency, but will work as soon as you flash the right Baseband (or a modem which makes it Penta-World-band).

BUT : The 1700/2100AWS bands are so special that many phones don't have the right antenna / the right chip / the right hardware for it, to "work well" (signal-wise).

Only a very few phones are True AWS <-> GSM "convertable" . That why I wonder if anyone has convert from 1700/2100AWS to GSM and confirm it works well enough.

Thank you.

1700/2100 AWS IS GSM...it's just another GSM frequency. The Galaxy Nexus, Nexus 4, and other pentaband phones are also proof that it's entirely possible to design a phone whose antennas function well on all those frequencies.

However, the baseband software (i.e. radio) may have different parameters for radio signal strength, and who knows what else that are tailored for a specific region (i.e. make phone pick up 850Mhz band more quickly or optimize X process etc.), but since those radios are closed-source binary blobs, we don't really know what the hell was changed there, so the only way to find out what works great for you is trial and error.

Advantage baseband I9250TDVMK1

Hi ,

This is a good thread to know about all related to galaxy nexus baseband. I would share a result which can help other to decide -

I bought GNEX in Canada and was looking for WB-AMR capability. Tried some basebands from AUSTRALIA , based on info that Telstra is using WB-AMR with GNEX.

Baseband tried -
I9250TDVKK6
I9250TDVLF1
I9250TDVMK1

Result -
None of these versions actually enabled WB-AMR support ( I also changed the build.prop file for WB-AMR support). Information is concrete because I looked at the protocol negotiation with the network and GNEX did not reported support for WB-AMR.

Latest baseband (I9250TDVMK1) has an advantage. The handling of 3G HSDPA is much better. The other 2 baseband would try to connect to network immediately when there is data , bringing GNEX out of idle. The DVMK1 will actually buffer the data and will trigger a connection towards network after a certain threshold. In my testing DVKK6/DVLF1 were getting out of idle mode 3 times more than DVMK1. What this means is better battery life. I tested at same location one by one therefore nothing external caused this change of behaviour.

Just got these speeds with the UGLL1 baseband on T-Mobile USA in South Florida (at 2 am, I practically have the cell tower to myself lol)

DVMK1 vs UGLL1? Is the "latest DB#" worth it? (And what's it for to begin with)

Up to you entirely. Let us know if the newest DB# seems better than the latest built in your area. :good:

P.S. for everyone: I just rehosted all the files on BasketBuild since Dev-Host has been peddling adware apks lately if you don't run an adblocker..

I'll leave the Dev-Host files up as a mirror for the counts and sorting, since BasketBuild doesn't support sorting by upload date (yet).

@osm0sis,i'm always use your 900colorsettings script,today after flashing a new rom ,i didn't find the script in basketbuild all the scripts are diffrents in names but exactly the same (look bellow) ,and it havn't any relation with tweaking the color of screen as i know

@osm0sis A fast answer will be cool [emoji56]

Not the correct thread, but yeah, clearly something messed up when I was uploading. I'll fix it in a bit, either tonight or Monday since I'm already busy.

Two points:

1) This is not the correct thread to discuss that. This thread is for GNex radios.
2) osm0sis is under no obligation to update anything, so please don't make posts like "when is it coming" or "waiting", etc.. You already made him aware of the issue, and he'll update it when he updates it.

Thank you.

Turns out everything I uploaded to BasketBuild was corrupt... scripts should be good now, but now on to the far-more-tedious reupload of ALL the radios, in order... again.

Of course, for the impatient, everything we're talking about has still been mirrored on my Dev-Host all along. Just use an adblocker.

@osm0sis How to flash these radios with TWRP? they are in CWM format

osm0sis · Nov 19, 2014

There is no such thing. It's a label. Just flash them.

um ah.....I am using twrp 2.7.0.0 . When I try to flash different radio it gives following error.

Unable to open zip file...error flashing zip.

My /sys is ext4 and rest are f2fs
