[Q] Kernel & Baseband difference?

I´m pretty new at this so... as the topic hints; Whats the difference between Kernel & Baseband?
Is the kernel like the core of the Android OS, and the baseband (kernel too?) is all the drivers for 3G, Wi-Fi, GPS and so on?

Yes, you got it quite correct. The kernel is the core of the system, while the baseband controls all communications for the device. Seeing that you are new here, you may want to read here: http://forum.xda-developers.com/showthread.php?t=1466228 (it can help a lot).

Actually, unless you're talking about iOS, the kernel actually controls all that. The baseband is merely a piece of firmware (a type of software), that controls the radio in your phone. The kernel has all the drivers for everything else, including camera, bluetooth, and wifi, built into it.
In the case of iOS, the baseband actually has the drivers for various hardware components built in, go figure... exact opposite of android down to the code

Thank u all
Thank u all! I've learned a lot here.

thanks for the information... was updating my Atrix 2 firmware and was confused as to what a baseband was... this cleared up my doubts... :victory:

Does the baseband serial number (XXLPS) needs to match the Kernel Serial number (XXLPS)as well?

ROM and Baseband
Do we need to match the ROM baseband and installing it.. IF I have a device samsung 7300 and any ROM which is for 7300 will work on my device?

rom
is the base band necessary for installing rom on android device?

not instructive

The definition there (for BASEBAND) is a rip off from wikipedia (or viceversa). Also, it is hardly useful for people just wanting to flash once or twice :silly:
How can we update?

Yes it works.

Now these are clear to me.. I have rooted and updated so many phones. but now only I know:cyclops: what the base band is. Thanks

Do you need the latest baseband to get the top speeds? I update mine and have 3g but on a phone without a changed baseband gets 4g. The changed baseband is on a sprint galaxy s4 getting 3g and the unchaged galaxy s3 gets 4g. Why is that? Do I need to downgrade my baseband for better speeds?

Can I flash a t-mobile baseband on a AT&T d800 if my carrier is t-mobile or do they Need to match?

The baseband for my device, is it device specific, hardware specific, or universal? I mean, will a baseband found from an MTK6582 chipset phone work on another phone with same chipset?

this is not related to the baseband
it's about the phone pieces (hardwares) so u have nothing to do about it

[Q] Which model is my Nexus S exactly?

Total noob here.I have a Galaxy Nexus S GSM phone running ICS.I do not know the exact model I have I suspect I am having the M200 variant.The guy who sold it to me in all probability rooted it to install ICS.I want to install Jelly Bean on it.My questions are(Please forgive the wall of text, I wanted to be as elaborate as possible)
1) How can I know if my phone has been rooted ? Can you install ICS without rooting and without an OTA update?I dont know what the previous owner did.
I found out that I have an unlocked bootloader.But When I try to install and run Voodoo Sound which requires a rooted device.It says
"Sorry,this device doesn't run a kernel supporting extended sound controls"
can I take it to mean the device is not rooted?
2) Can I find out definitively if my phone is M200 Nexus S?
Baseband M200KRKC1

FASTBOOTMODE

BASELOADER : I9020XXKL1
Baseband M200KRKC1
CARRIER INFO KTT

I pulled out the battery and it just says i9020 on the back of it as well as the phone box.The box also says made in Korea and it was imported into Romania. (I live in India and i bought the phone someone imported into India )
MY IMEI starts with 3569 if that helps
3) I want to install Jelly Bean and no OTA update here.If I do not know conclusively if I am having M200 will it brick if I install 9020T Roms, I remember reading somewhere they are very similar and some early unofficial Jelly Bean builds for 9020T worked on M200.I do want to install Jelly Bean that is why I am looking at the Nexus Oneclick Tookit.Does it differentiate between M200 and I9020T builds?
Edit: I checked and I need to know model SOJU or SOJUK
Any help will be greatly appreciated.Thanks in Advance
I looked at these threads but I cannot conclusively say this is an M200 version

I am 99.99% sure I have M200 and I think so do you
I did a lot of digging and I found these links.Apparently I cant post the links directly.The first two are secured and the last one is just regular.Just add in front

randomphantasmagoria.com/firmware/nexus-s/m200/
Now check this with someone before you do this but I think you can just go to settings>About phone>System Updates>check now
Ideally this should update to ICS 4.0.4
I think Over The Air(OTA) updates should be safe for your data and is ideal for people like me who are new to Android.Just get this confirmed with someone who knows about it and you should be able to upgrade.
I think you should be able to upgrade to ICS.My problem is different.There is no JB out for M200.

I checked with an app called android system info. It says my model is nexus S and priduct is Soju. On the factory image website of google, i saw a factory image JB for nexus S. Not sure what to do now. Also, i tried the OTA update, it gets stuck at the White triangle with green droid screen. I desperately want to shift to JB or ICS.
WHAT TO DO???

U sure it says Soju and not Sojuk?Mine says Sojuk.If only I had known it was so simple to find out my model

Just go to settings-> about phone and look at the baseband. The model is the one before the XX. e.g I9020, I9023, m200 etc
By the way there is no Galaxy Nexus S, it's just Nexus S or Galaxy Nexus, no combinations of the two.
If the phone is rooted you should see superuser in the app drawer.
Just use the search function to find out how to install jellybean on the m200, it's been answered

i am also having the same problem . If you finally able to update your phone to ICS than plz do tell me how you did it. I am worried about the same issue? Email : [email protected] skype name tosif3d

You have a dev phone so I don't see why you don't want to root your phone. Just look into the advantages you get from rooting once (again) and then decide for yourself!

good day guys! please help me with my problem.
i have recently bought a used nexus s. i have acquired this phone because i know that it uses the wolfson audio chip and i want to make it a music player by using the voodoo sound app (this app needs root access). my problem is i don't know what version it is hence i can't root it for fear of flashing the wrong kernel and bricking the phone. i'm in the philippines so if the phone was bought here, it must be an i9020 international version. besides, there are no korean apps or characters present. i took a picture of the sticker under the battery and saw texts in korean and then it says SHW-M200K at the end of the first line. i know that this is the code for the korean version. so is it right for me to assume that i have the korean version? but then again in the fourth line of the sticker i saw text that says FCC ID: A3LGTi9020. this is the code for the international version so i'm confused. when i checked the settings, about phone, it showed android version as 4.1.2 and baseband as XXKI1. lately i saw a korean version of the nexus s and the baseband starts with M200..... however, my phone's baseband is XXKI1. i'm really confused please help me. i'm planning to root this using this toolkit but i don't know what's the version of my phone.
here's the pic of the sticker under the battery:

You can use one click root toolkit by M.sabra.. I'd done that on mine and working perfectly..:good:
but mine one in baseband version shows m200

Well, at least I am sure that its a GT-i9020T

thank you for the reply brother hito. yes that's what i'm confused of because my baseband says XXKI1 and no M200 prefix.
brother DJBhardwaj, what do you mean by GT-i9020T? you mean to say this is the international version?
thanks.

As somewhere i read on the internet that you can change your baseband version by changing radio..
I'd take some of pictures of back but didn't get clear anyone of them, said i've no other camera so you can see mine one board..
You can check your IMEI number online and they will tell you what your model number actually is..
----> http://imei-number.com/imei-number-lookup/
Or anyother site you may check...

thank you very much for your help brother hito. as indicated in the IMEI lookup, my device is a korean nexus s with model number SHW-M200K.

Can you tell us what build version it is, you can find this by going to settings->about device then scroll to the bottom and you'll see build version.
Then you should be able to google the firmware and find if it is compatible with superuser or SuperSU.

HELP: older stock ROM for SM-G930FD needed

Please help me find a stock ROM for the dual SIM/duos version of the Galaxy S7 (model no. SM-G930FD) that is prior to the actual version (baseband G930FXXU1BPH1, build no. MMB29K.G930FXXU1BPH6 / Android-Version 6.0.1.). I believe that the actual version keeps WiFi from starting when the second SIM tray is occupied with SIM AND SD card simultaneously.
Please help with links to and sources for older stock ROMs for SM-G930FD).
Thank you in advance.

You have specify your search depending on what firmware version you are looking for just make sure that it is for the correct model of your phone
