[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

[noob question]Lollipop RIL

I know this sounds noobish, but can't we use files from other phones that have the same hardware? For example, MotoG (which runs the same chipset - s400, which has an integrated modem) already has official lollipop.

I'm waiting for one max by AT&T to get lollipop to try using its files to fix our lollipop rom.

xXminiWHOOPERxX and lawsuits are our only hope for Lollipop.

One Max started to recieve Lollipop in Taiwan! XD

Downgrading SM-G361F ( Samsung Galaxy Core Prime ) 5.1.1 to 4.4.4

Hi I want to downgrade my Samsung from 5.1.1 to 4.4.4 ( SM-G361F) , can any one give me a quick help, I am not new to this, so if someone can explain in a few steps.
Thanks in advance.

you canțt there is no 4.4 rom for 361f only for 360 variants. you are stuck to 5.1.1

Most newer Galaxy phones have an eFuse on the board that prevents downgrading the whole firmware. You might be able to use a custom KK rom, if one is available, but will not be able to downgrade with Odin and the official firmware/software package.

Cant Diwngrade
"There Is No Actuall Way Yet The Mother Board has a vChip that protects Maleware and untrusted files from overwriting the system . Finding one is no luck i took my into samsung store they swapped it for a 4.4.4 Samsung Galaxy Core Prime G361F i would just ask them" ¤☆》《
Also Its a Efuse
Thank you for taking time to read this

why would/do you want to downgrade?

So no way downgrading sm-g361f from 5.1.1 to 4.4.? We have chance install 6.0 to sm-g361f?

it's because of that, that after i flashed a custom kernel a red "!" mark will be always at the top left of screen when phone is turning on? dose that means i did blow up the eFuse?

Would you know what lollipop firmeworks works on model SM-G360G, like 4G everything works ok here, vodaphone model. Sick of waiting for lollipop, or should i just wait....I noticed some people had used a Euro Firmware.

There Is Actually One Way But This Causes To Using A Different Model That Is Not The Same As You Android Device Or Changing Your Model To A Different One As The Same Phone As You Have But Having To Have 4.4.4 KitKat??

SM-T330 vs SM-T330NU (kernel compatibility?)

Hello, everyone!
Brief history:
I own a Samsung Galaxy Tab 4, 8", model SM-T330, which I basically use for work. Lately, the app I use the most has launched a new update which only works on android 6.0 versions and newer. Since the latest update available for my tablet is the android 5.1, I tried searching online for alternative ways to update it, so it can suit my needs (which is btw how I ended up finding this forum). However, I only seem to find the updated kernel (6.0 and 7.0) for the SM-T330NU. I have done some research on these models and it seems that the only difference between them is that the later was designed for the north american market, although all the specs are essentially the same.
Quick question:
Anyway, is there any possibility to update my tablet with the SM-T330NU kernel? Will it work or is it more likely I'll have my tablet bricked?
PS: I don't plan on buying a new device if there is a slight chance I can get it updated by any means necessary.
Thanks in advance!

You could think to flash a custom ROM. Which app is this? If it's an app of videocall, neither custom ROMs can help since blobs are of lollipop and can't support Android 6.0+ apps.

Can I upgrade Samsung Galaxy Grand QuattroI8552 from 4.1.2 to lattest android?

Greetings!
It has been more than 7 years since I used Odin to re-install android 4.1.2 to my Samsung GT I8552 phone (I have ever since moved on to iPhone) By then android 4.1.2 was the latest. Now that time has changed and tech has grown, Can I do a clean installation of the LATEST android version (I checked and there is 6 and even 8++??) to this same old phone? Is Odin still the way to go? Please guide.
PS: I checked this link and it shows that the latest update was in 2015 and the latest version is still 4.1.2? I'm not clear what it means to this old model.
Thank you.

Update and Upgrade are 2 totally different things:
Update patches an existing Android version
Upgrade replaces an existing Android version by a higher versioned one

Look inside here to find out what are the minumun hardware requirements for an Android version and compare them to your phone:
