Hi guys, I have a generic knowledge about phone, rom and stuff but I want to understand it a step deeper.
Can someone give me info about :
1. what is the importance of upgrading Baseband ?
A. Do baseband are different for any region (America, Europe, etc.)
B. Is there problems that can happen when changing Baseband ?
C. Can i use Android 4.0.4 with old baseband like V10A ?
2. Differences between baseband and IMEI ?
3. Differences between V30B, V30C etc. (What it mean and what it do.)
4. What is Governor ?
I really like to test and try new roms, changing kernels and stuff but.. I need to understand this better.
Thanks guys !
1 Maybe this help.
2 IMEI

4: Here.
I help you giving you links, now is time to read.

Hey everyone. I am very interested in rooting, and hopefully flashing once i have done the basic root first. Please can you answer each question I have an Orange branded SGS GT-i9000. Here are the specs:
FW Version: 2.3.5
Baseband Version: I9000BVJV3
Kernel Version: 2.6.35.7-I9000BVJVC-CL679241 [email protected] #2
Build Number: GINGERBREAD.BVJVC
Question 1: do i need to know the whole of the kernel or just part of it?
Question 2: I always see rooting guides saying 'How to root (FW version) JV(something). Where does the JV come from, as i have 2 types of JV, JV3 and JVC. So what does rooting depend on other than firmware version?
Question 3: I have noticed the Orange firmware is a different JV. So how do i know the root will work with my version as the root guides are always on stock roms?
Thanks in advance : )
Hello Tarnwilliamson, I think I am in the same boat as you, I also am on Orange with the same spec phone as you wanting to root. I was just wondering have you found out anything about rooting this phone? I have searched dev and q & a section but there seems to be no posts on this topic. I dont want to start a new thread so I though I would ask you first. Thank u in advance.
hello
You may try with Super one click root or try to flash your rom with odin to STOCK ROM (i have I9000xxjvu for example) and use CFROOT for your rom with PDA in odin. That gives u the root accsess, superuser and busybox ( CFroot IS A KERNEL) it is many subject on XDA.
Hello Marcinrek21, Thank you for your reply. As my Build number ends with jvc isnt there a specific file I need to flash with if using Odin? Or am I mistaken and I can flash with any cf root file as long as it is for a gt19000? As for super one click is that still compatibable with 2.3.5 as I remember reading somewhere the bootloader may be locked with gingerbread? Thank you in advance.
Hello All.
I had a small talk with DoomLord about flashing base-bands over the phone and the difference it would make for your phone so have decided to make the information that I got available for the public here so that no one else has to go to the same hassle I did Googling for all the stuff.
I am a power user of Android. But completely unbeknownst to the development side of the OS. So if I make any mistakes, I request you to point them out to me and I will make the necessary corrections.
So what exactly is a baseband ?!
Inside of your cellphone, there is a chip embedded that enables it to communicate with your carrier's transmission towers. This chip is known as a "baseband processor" and it is responsible for signal processing and realtime radio transmission operation. (Got that bit from WikiPedia)
The baseband is actually a piece of software that instructs that processor on what frequencies to operate on.
Kind of like a driver for any hardware that you might install on your computer.
So any gain in the level of harmony between the hardware and software that make data transmission happen on your phone (GSM/DATA) is only going to benefit the phone's performance. ( READ battery life, signal reception, etc.)
Also, each baseband has it's corresponding libraries which also need to be provided for it to be working optimally.
So that's that for the theory part.
I'm open to corrections. If anyone can point them out, I will be happy to edit the post. But I had a lot of trouble trying to understand WHY I should flash a particular baseband and what difference it will make.
Currently, at XDA we have baseband patches for baseband -36 and -64 available.
So as per your ROM requirements, it would be better to flash any of these base-bands onto your phone with their corresponding libraries.
Which brings us to the next part.
ACTUALLY flashing the baseband.
Pretty simple process actually.
But from what I know, you will need a rooted phone with an unlocked bootloader to do this. (!! Not sure !! )
And a custom recovery (Clockwork MOD) that can allow you flash .zip to NAND.
EDIT : You just "NEED" root. (Thanks Flo95)
Please follow post 2 for further info on how to do it without root.
My ARC S is rooted and has an unlocked bootloader.
So all that you need to do now is download the following :
1.Flashtool.
2.Baseband that you require.
3.Corresponsing baseband libraries
I will be posting more on this with screenshots so that everyone can enjoy the same benefits that I have currently after using my phone on -36 baseband and using the corresponding patches.
Credits to DoomLord (For awesome DOOM Kernel) and Iridaki (For baseband patches). If there is anyone else to credit, please do point and I will acknowledge the same here.
I invite inputs from other experienced XDA members to provide more technical Know-how on why this is necessary. Sadly, there is insufficient material right now on this topic here.
Thanks.
EDIT :
Lets share a list of working Basebands in various areas :
For eg. :
Gujarat, India : 36 works fine on Vodafone 3G
64 works fine on Vodafone 3G and Airtel.
NSW Australia (on the Optus network) : Baseband 36 tested to be working great
Finland:
-64 works great for Sonera / Saunalahti / Elisa / DNA
-36 drops connection alot for Saunalahti / Elisa
Croatia
baseband 56 works great in Croatia
You can point to the baseband working for you and your location and I will update the post accordingly.
Thanks
Please click the "THANKS" button if you feel you've benefited from the info !
You can flash basebands without an unlocked bootloader, as it happens when "normal" users update their devices the official way without need of an unlocked bl.
You can get recovery with SE Extreme Tweaker on locked bootloader, too.
Only thing you need is root.
But for kernel awesomeness I'd definitly recommend to unlock the device.

Thanks for this topic!! ok I attach here the post I published in the other thread with no answer :
" @Iridaki: Sorry for my stupid question... But is there a way to flash another baseband directly from recovery?? Or I don't know, with root explorer... I'm on firmware. 42 rooted, with locked bootloader and with recovery. Thanks!

I think this is a great idea to discuss what basebands work best in what areas, it will certainly help a lot of people make the right (and informed decision).
To start off, I am in NSW Australia (on the Optus network) and I have found that the ideal baseband for me is .36 - All the other ones work fine of course but the .36 offers best/optimum battery and radio output for everyday use (with the latest DooMKernel of course!)
Hi, Im from the Philippines and wondering what baseband suits for my Arc S?

Yes there is a way to flash the baseband without Flashtool, but we wont publish it for now, since it's not working reliable on me. For theorie its working like an SE fota update. Which uses binary diff and flashes the diffs to the corresponding areas. This way you could flash all partitions. But this is only theory for now, because with flashtool we have a better way which is very very safe. Even if flashtool fails the phone can be restored everytime. Via FOTA you can really brick it forever
@All asking for which baseband fits best:
Please please DON'T start flashing basebands without thinking about now.
Normally ALWAYS use the baseband which comes with the ROM! For example SE always has the corresponding baseband included. This baseband fits the android libs it comes with.
On custom Roms please read what the developer of the customRom telly you. If he/she has developed the Rom for specific baseband libs.
All other things like baseband patches are tested and developed by other developers which know what they are doing. So if you use such a patch ALWAYS read the manual and the requirements. Because it CAN happen that it is NOT possible to use a GB baseband on a ICS rom and vice versa. The is a little more than "just" libs and firmware. Also the java part framework/base/com/java/internal/telephony....
has to fit the baseband (SE is very special here).
So i hope now you all understand. Please please please leave the decision which baseband is best and which is working to the devs who know what they are doing!!!!!! Don't come here and tell "i tried baeband xxxxx now my phone randomly disconnects data/voice/..."
Thanks
I'm in Victoria, Australia on the Telstra network. Does anyone know which is the optimal baseband for me to use?
Cheers.

Hehe, maybe just a little bit. The rest of the post was supposed to read that I am currently running baseband 64 but have **** internet connection even with full network reception.

ive been using baseband 36 so far, not bad might try 64 soon
Hi everyone,
I have a question that may seems a bit noobish here about the baseband version indicated in the posts regarding custom ROM flashing.
My phone shows the following baseband version number: I8190XXALK1. Is there any compatibility issue with the roms currently listed in that forum ?
Basically, is there any risk for me to brick my phone when installing a ROM for a I8190XXALK6 baseband ?
(Oh and by the way: happy holidays everyone ^^)
Hi
Optimus rookie time. I have tried to understand from the faq but no one has answered this specifically that I can see. I'm in Australia, I have got an O4X from Kogan. It has arrived and has lots of Asian menu's, I have no idea if Taiwan, China or Singapore perhaps so far. It has lots of apps with 'hama' in the names if that helps. This is what is listed in about phone:
Software version: LG-P880-V10d-OCT-16-2012
Build number: IML74K
Baseband version: L6260_MODEM_SIC_02.1216.01
Kernal: 2.6.39.4
I would like to try JB, I get some people hate it, some say it is ok. If not, back to ICS or CM. Which JB firmware do I go for, the euro version or must I get the right regional version for my phone?? If so, can anyone tell what is is or is all that is important is v10d?
Thanks for any advice
Hi. I also got my 4X from Kogan, so I've been through the issues you've mentioned.
First thing I did was update to 4.1.2. I didn't spend any time with ICS, so I can't comment on differences - I WANTED JB and that was that! :cyclops: To update to 4.1.2, I used the LG update software – info about this procedure is here: http://forum.xda-developers.com/showthread.php?t=2069723
To check which version of the LG software to use, I used this URL: http://csmg.lgmobile.com:9002/csmg/b2c/client/auth_model_check2.jsp?esn=
You need to put your IMEI (from Settings / About phone / Phone identity) in the url after "?esn=", and it returns the URL of the software you should download to update your phone. That told me to use the Taiwan version - I don't know if others (eg Europe) are compatible with our hardware - would be interested to hear!
2nd step was to root the phone (as an Aussie, you need to ignore the obvious sexual joke in that phrase!) – I used the instructions at http://forum.xda-developers.com/showthread.php?t=2180688 with some help from the better English at http://www.lg-phones.org/how-to-root-lg-optimus-4x-hd-android-4-1-jelly-bean.html [NB – the comment below this points out some errors].
The next step was to install Titanium Backup and use it to remove all the non-English apps. I had no problems with that step, so whatever they are, they're not critical.
G'day, nice one. Will look into links later. Appreciate the reply
Thinking about this a bit more, if you only want to flash the "official" (Taiwan, in your case) updated firmware for your phone, you can use the LG Update tool "as is". The instructions in my earlier post can be used to flash other versions and a lot of people seem to be using the Euro 20A. I'm out of my depth here though, so hopefully someone else can confirm:
Can any version (ie any country) firmware be flashed onto any 4x?
Ok, all done. Running jelly bean fine. Think it better than ics, using iodak kernel. Thanks for help. If anyone comes across this thread, when flashing to jb using kdz, the 100‰ battery is essential before flashing

Hello all.
Firstly, i strongly appologise if this post is in the wrong place etc, and i really have tried very hard to search through everything without having to post but i'm so lost i need a point in the right direction. There's just way too much info on the forum, and links, and threads, a lot of it assumes you have a very detailed understanding of custom android roms etc etc and i'm going round in circles.
I have a Samsung Galaxy S GT-i9000, purchased in the United Kingdom and on o2 network.
It is not currently rooted, however i am preparing to do this also.
My current Firmware version: 2.3.6
Baseband Version: I9000BUJV4
Kernal Version: 2.6.35.7-I9000BUJVG-CL719381 [email protected] #2
Build number: GINGERBREAD.BUJVG
I want to root and then flash a new rom to my phone as currently it is SO slow i can barely use it so my main aim after rooting the device is either to remove a load of unnescesary apps and streamline the stock gingerbread rom OR update to a stable rom that does not come cluttered with lots of apps. I can soon add the apps i want or need.
With there being SO much information on i9000 and the info being a bit dated (handset is very old model now by todays standard) i'm just overwhelmed with too much or conflicting information. I really would benefit from someones knowledge and advice.
Firstly i do have Odin and the PIT files.
Secondly i can't seem to find matching relevant files to be able to root my handset as nothing seems to match what i see on the 'ABOUT PHONE' screen and as listed above, nor can i see a stock rom that matches my info.
Thirdly, i'm considering something like using: [ROM][GB][JW8] MesoROM v2.0 but don't understand the instructions (they assume you have flashed roms to and from the handset before). I cannot establish from my phones info whether i am all set to begin with some of these roms as some are labelled JW8 and referred to if you are on Gingerbread JW8 or not etc and i don't think i am as these letters are not meaning much to me at present. The references to using certain kernels (eg semaphore) have confused me also. I need things dumbing down
I am confused as to the order i need to begin. I have attempted nothing yet, due to not being able to get my head around everything 100%. I don't understand the seperate parts of Odin, and which i must flash and which i can leave as standard, i have flashed Samsung galaxy Aces handsets using CWM before but i just desperately need a list of the order to do things and confirmation what files are a compatible match with my info not seeming to match any references on the forum.
If someone could inbox me or just simply point me in the right direction i would be so grateful. Any order to work from no matter how brief would be very helpful.
I understand this post must look like i'm not making any effort to read or search but honestly i have and appologise for coming across as a complete idiot, i have tried vigourously to learn about flashing these handsets i'm struggling to work out the correct files to get going with, and their relevence to the operation of the phone.
Thanks for your patience.
Drew
Additional info
In Samsung Kies the current firmware lists as:
PDA: JVG / PHONE: JV4 / CSC: JV5 (VOD)
This helps make sense of some of the individual rom instructions but i am still a little confused... which is kernel and which is system os / firmware so to speak?
I believe i want the Semaphore 2.74 kernel but completely don't understand the abreviations used within the instructions.
Will that kernel work happily with MesoROM v2 rom, and what order to flash via Odin etc? Just can't get my head round all the jargon. and all the JV4/5/6/7/8/9 references.

Yes, it will work.
BTW, Semaphore 2.7.4 is a stock kernel in MesoROM v2.0
Thankyou, all working with MesoROM and Semaphore. Really pleased
