Are you looking at flashing custom ROM's or just changing your baseband?

My question is, if it matters which baseband I use with a specific rom,
or does every baseband work with any Rom ???

works for any rom.

That irritated me at first too. No idea why SE has that kind of problem. But here it doesn't matter for flashing roms. Its only important signal and wifi strength

many thanks to all

There may be recommended radio's to flash, but there's no requirement - all what works best for you!

Well by the sounds of it your not planing to root your device (at least straight away). Although if you do decide to purchase I recommend it as there are numerous fixes with custom roms/kernels. The battery out of the box was shockingly bad but this was quickly fixed by flashing a new kernel and it improved dramatically!! The other issue out of the box I had was the signal dropped out every so often but you can flash the latest baseband and that resolved the issue.
Hope that helps...

i'm planning to root my device...but maybe 1 or 2weeks later...for the battery fix,which kernel should i flash?is it a custom kernel or a stock kernel?
and for the signal drop issue which baseband should i flash?btw...is baseband different in every country?? i'm a noob

It depends on the rom you might flash. Some like CyanogenMod have a modified kernel that improves performance and battery life anyway. I personally like Francos kernel but it some what depends on your experiences with different rom/kernel combinations and experimentation.
As for flashing the 'right' baseband, there are different releases depending on your location. However this is not to say that a asian baseband won't work in europe (they do). So again this calls for personal experimentation and seeing what works best for you in your area.

i'm going to stick with the stock ics first...wat is the ics version of nexus out of the box?4.0.1?if it's 4.0.1,how do i upgrade it to 4.0.2 or 4.0.3?if i flash Francos kernel,will i lose my data and apps in the phone?
i'm from malaysia(asia) so which baseband do u think i should flash??
again...i'm a noob...i really appreciate tat u answer my question...thanks alot...

The version out of the box will more than likely be 4.0.1. If your planning to root anyway then you don't need to worry about what you get out of the box.
If your bootloader is locked (which it probably will be) when you get your device you will need to unlock this. Doing so will wipe your device so it's recommended to do so sooner rather than later.
EDIT:
After this point flashing a new kernel will not wipe your app data (unless you want to )
There are 'stock' rooted roms available, I but I believe these are limited to 4.0.1/2 only. If you want great performance I would recommend a custom rom.
The Toolkit (here!) is a great tool if your new to the whole rooting scene so I recommended looking at that.
You can have a look at the list of basebands as well (here!) which might make the situation a little clearer. There's no 'easy' answer, as I said before you need to do some reading and self testing. Everyones situation is different depending on exact location and rom combination. Don't be afraid at trying these new things (you can always flash a different one).

now to think of it...maybe i'm not gonna root my phone...cuz it void my warranty and galaxy nexus cost a looooooooooooot in my country...it's really expensive...
i'm sorry but what is bootloader?
thx again for your help...i'm doing some research about all this procedure right now...

As far as I know (I may be wrong), unlocking the bootloader and rooting the device does not void Samsungs warranty. Even if it does you can relock the bootloader/unroot your device so there were no signs of you tampering with your device in that manner.

Try aokp with Franco kernel.

No. The newest official version is 4.0.2.
In the development section of this forum there are 4.0.3 roms available because they are in aosp but 4.0.3 never never got pushed ota. There are leaked 4.0.4 roms too.
To flash a kernel you need to unlock your bootloader, flash clockwork mod recovery and flash from there. Don't flash Franco.kernel over 4.0.2
Just use the gnex toolkit to do everything, its simple.
Then read about bootloaders, adb and fastboot.
very valuable knowledge.

It will update to 4.0.2 from 4.0.1 when you turn it on and it will upgrade Over The Air (OTA)
Aosp is android open source project.
All the code for android is free for people to take and build and is stored in Google's aosp repositories.
Read as much as you can, nexus are quite simple so you'll figure it out.

Locked Bootlader: What rom available?

Ok, i understand that ICS is just not good for gaming. I have a R800ì root LOCKED BOOTLOADER. Can i still do some flashinf roms, etc etc? I'm new in these things, but i think it's time for me to begin. If i want to keep my bootloader blocked, what can i flash? Is it possible to flash Xperia NXT 1.2 rom, DIxperia 2 rom, TrueAncestor rom, etc etc?
And most important. BEFORE i do anything, is there a way to back up everything EXACTLY as it was, so i can go back to my stock 2.3.4? Thank u for your time guys:good:

Hi, assuming you are rooted, yes you can install some rom that are compatible with locked loaders. The ones you mentioned are all compatible, provided you flash the specific fw that's indicated in each of those rom
You can do a nandroid backup to backup your current rom exactly like it is right now, with cwm. Just download x parts from the market

Ansother thing: with a locked bootloader what i cannot do? Change kernels?

My favorite so far is Gin2JellyBean 1.8.1, i still have my bootloader locked, it has some bugs like weird looking home screen when it's in landscape mode but still very smooth and great looking :silly:

[Q] Play 3G Problem

Hi, I have a rooted xperia play R800i (unlocked bootloader and no simlocks) with stock rom 3.0.1.A.0.145 and 3G works fine (baseband 21-22). When I flash any other stock rom with higher baseband (tried 36, 56, 64), I lose 3G signal. I only get 2G connections. When I go into settings->Networks->Mobile Networks->Network Operators, I see only 2G operators. I have a Singtel connection (2100 mhz). On all firmwares I have tried, service menu says I have UMTS_1 UMTs_8.
The reason I want to go to new baseband (atleast 36) is to have custom roms and ICS on the phone. Giving up 3g is not really an option.
I have tried flashing old baseband after flashing custom roms (using flashtool, exclude system and kernel and then copying libs manually from old firmware for baseband) but I keep getting unknown baseband in settings->about phone. There is no voice or data signal if I do this.
Any suggestions to fix this problem will be very helpful.

Have you tried just the baseband for .79? Its a world FTF.
Here is the link from my collection:

I also have a baseband that I am using its .80 baseband, I have the FTF and the flashable files for it as well. I was getting edge where I live, in the mountains, after flashing .80 I went to HSPA+. Big difference in reception strength and stability for me.
Let us know how it goes.

Hi,
Tried both basebands and still the same problem. Flashed whole 79 ftf and no 3G, tried baseband 80 with libs, still only 2G. 3G works fine as soon as I install the old ftf. A strange pattern I have noticed that I would like to share. The only firmwares that have worked for me are the ones starting with 3.x.x.x, anything with 4.x.x gives the same problem. Here are the firmwares I could find and I tried them out and they work fine.
Xperia PLAY_3.0.1.A.0.145_UK
Xperia_Play_2.3.3_UK_Generic
These basebands havent worked for 3G

Are there any 3.x.x firmwares available I haven't tried which have basebands which might work with ICS? That would solve my problem I am guessing.

Yes have tried installing DoomKernel ICS with stock ICS over 3.0.1.A.0.145, I get no network detection and get an Unknown Baseband in about phone. Also tried copying ouver the 7 lib files from the working rom into this setup but same error.
APN settings are the same across firmwares.

[Q] Ion says Bootloader Unlock Allowed: No, Can I install custom ROMs/kernels anyway?

I've been trying to buy a Sony Xperia Ion (LT28AT) for use on T-Mobile USA where the bootloader is allowed to be unlocked. So far, all the devices I've looked at all say No.
I know I can still root an LT28AT where the bootloader unlock allowed = No, but I can't install custom ROMs and kernels, right?
But from reading threads here it seems some people can still install custom ROMs and kernels where the answer is No. Can anyone please clear this up for me?
Thanks!

With a locked bootloader you can use roms that are stock-based.
With an unlocked bootloader you can use roms that need another kernel, just like miui, cm 10 etc

Does that include CyanogenMod ROMs like CM10, CM11 etc?
Also, with a locked bootloader can anyone tell me if I can install any kernels that will overclock?
THANKS!

CyanogenMod Roms need their own kernel, and to flash this kernel, you need an unlocked bootloader.
You cant flash any custom kernel on a locked bootloader.

You must unlocked bootloader before flash another kernel.

U can actually flash cm 10 on u a locked boot loader... A developer @mrgeez is working on making cm10 rom for locked bootloaders... Some roms work on locked boot loader and some don't... But ideally don't buy a cell with locked bootloader.. Causes to many problems..

What's inaccurate about it? This is an exception because they managed to get CM10 working with a stock kernel. You can't get any higher versions though because those require an appropriate kernel that isn't stock anymore. There have been a lot of kernel changes between Android 4.1 and 4.2. So on locked bootloader you can install stockbased ROMs (like eXistenZ) and one particular version of CM10. Impossible to flash a custom kernel.
Unlocking the bootloader also has downsides though. Beyond Android 4.0, the Mobile Bravia Engine stops working on an unlocked bootloader. Without that, the colours are a bit more washed out, and the screen already isn't the most vibrant around (the Xperia S screen anyway, but the Xperia Ion screen isn't that different).

So really a locked bootloader means I can't install any kernels, And I can only install ROMs compatible with my existing stock kernel.
