I have upgraded to XXKG6 on it, but I don't like how modem of XXKG6 works, and I want to downgrade it to XXKG5 version, and it seems to be a little bit buggy and problematic (I've read on google, and I tested myself already, the signal is not as strong as before and the battery drains a lot faster when Wi-Fi or 3G is enabled compared to XXKG2). Well, I want to remain on the same XXKG6 firmware, but with XXKG5 modem, it is possible? or I may brick my phone?
How can you flash to modems at a same phone? No way it's possible. You either have to choose KG5 or KG6.
Regards.

Hi ,
I am using SGS2 from Germany (unbranded)
My initial firmware for KE2 and I then flashed KF2.
My current phone config is
Code:
PDA : I9100XXKF2
PHONE : I9100XXKF2
CSC : I9100XAKF2
Ofcourse as always for me, Kies is not working for firmware upgrade (is it because i have it rooted?)
Anyway I was checking the fiwmare details on CheckFusdownloader and found out today that the firmware for Europe is
Code:
I9100XWKF3/I9100XEUKD1/I9100XXKE7/I9100XWKF3
After downloading the file, the TAR looks like this
Code:
I9100XWKF3_I9100XXKE7_I9100XEUKD1_HOME.TAR
My questions are:
1. How can I map the above with Phone / PDA / CSC etc?
2. Is this the new firmware than KF2?
3. IS it worth moving to this firmware?
4. Would I be able to root?
My battery life seems to be somewhat improved from KE2 to KF2.
Thanks
The newest kernel is KG1 Gingerbread 2.3.4.
Move to KG1. Forget KF3. everyone's on KG1. Fixes battery life and other things Google talk+video.
It goes in alphabetical order efg so G is the newest KG1.
and I am assuming they are in order
So PDA then Phone then CSC.
My CSC is UNKNOWN LOL, true fact.
Latest firmware is KG2 and thats 2.3.3.
KF2 is slighly older than KF3 .
KG12.3.4 is not a Samsung release its a leaked test firmware .
Root yes read the root post in dev section ..
My view wait for 2.3.4 to be released by Samsung for next upgrade if phone is working OK .

1- As long as you are on stock firmware Kies won't make any difference, rooted or not.
2- AFAIK KF2 is the newer build than KF3 and the latest available for Europe.
3- Press *#1234# to see software info.
4- I'd say you should wait for official KG1 to be released. The current one is leaked and have bugs, so better avoid it.

I'd look up Lite'ning rom 2.2 if i were you...
Roots your phone, KG1 and all in there. Also Gingerbread 2.3.4.
Works perfect for me. Why wait for the official update. Modders will implement it very fast.
Good luck!
If you change to KG1 dont bother flashing the CSC, use the one you have at the moment.
I am not sure if there is much advantage to that KF3 based rom over KF2, so if you are happy with KF2 and dont want to jump to KG1 (which is working perfectly for me, I dont use stock browser) I wouldn't bother.
Yes you would be able to root btw, just use the KF3 kernel from chainfire.
Thanks guys for your feedback
BTW whats with CSC what will happen if I mess with it? phone will get bricked? lets s say if I flash CSC from another country will i be able to go back to Europe CSC?
Is this only for language?
CSC is only a few text files and xml files with lists of networks etc .
Not really needed for phone to work and a new one can easily be flashed .

So that means i can flash any country's SGS2 firmware? Whats with baseband? have any info on that?
Baseband = modem/radio.
Yes flash any firmware and enter the networks APN manually as long as its on the same mhz it will work .
But if you flash Chinese firmware it will have Chinese keyboard etc .
PDA = firmware including kerel
Phone = modem/radio/baseband
CSC = country specifics with a list of local networks keyboard to use language to use etc .
Many firmwares are multi CSC say covering most of Europe .

Thanks mate for the clarifications
one quick question. What happens if i try to update phone with multiple basebands?

You can't, the device can only have one modem at a time.
thanks infratech, I mean more of flashing one baseband and reflashing another version. sorry too bad in explaining

You will just replace the old one.
So I just got the Telstra Galaxy S2 on 2.3.3
I know it takes months of testing for carriers to upgrade to a major release such as from Froyo to Gingerbread but what about just upgrading from 2.3.3 to 2.3.4 how long do you reckon it would take them?
I am getting terrible battery life and want to see if 2.3.4 fixes it.
On the other hand, I realise if I cannot wait I can install the Australian stock unbranded ROM uploaded by intratech so if it takes too long I will consider that option but I just wonder what is the difference between the offical ones and the frankensteins?
It says it's for roms with multiple CSC's. But for the official XWKE7 there is only for CSC for Australia. However some users have requested the Optus CSC to be uploaded which it has.
I just wonder if you were to install the stock Australian ROM wouldnt that still work with Telsta / Optus / Voda etc? Why would users want the to have the optus CSC installed as well? I thought the idea of the stock's was to make the phone unbranded? What is the advantage of putting the Optus CSC on top of that? Is it for better network performance to make it work better with optus?
Since there is no Telstra CSC there will I be fine to install the official unbranded XWKE7 ROM and use it with Telstra?
Lastly once the Telstra modem drivers come out I could also install this onto the stock so I have the next-G optimised driver?
Thanks
CSC is mostly just apn settings for internet and mms and any Apps the carrier wanted to bundle. You can always manually enter your apn!
As far as modems go, you can seemingly use any modem with any rom/kernel, i am using the old ke7 modem with a kg3 rom.
As far as choosing a modem goes, it's a matter of trial and error to find the one which gives the best performance for you, for example 3UK just put out the KF2 modem, but it's not great for me.
2.3.4 is only available in kg builds the newest being kg6. KE7 is still a 2.3.3 build.
For me battery life improved moving into the kf's with wifi sharing frozen along with other junk but that would mean rooting.

Hello,
I'm sorry if this has been asked a million times before. I couldn't find anything that really answered all my questions.
First of all, I've see lost of roms that say are, for example, a KG2 rom. I'm assuming this means I need a KG2(or similar) baseband in order to use that rom. Is this correct?
If I flash a new baseband from http://www.villainrom.co.uk/forum/s...II-Shipped-Radio-Collection?p=42051#post42051 , do I just do exactly the same thing I did to flash a kernel(select PDA in odin)? Do I need to flash a new, compatible kernel at the same time? If so, before, after, doesn't matter? For example, I have a KF6 baseband and I flashed a KF4 kernel without any troubles. If I then flashed a KG2 baseband without changing the kernel, would I have issues?
Are the basebands numbered in order, e.g., KG2 > KF6(or newer at least)? I'm guessing this is why all the roms I'm seeing are KG2/KG3. I probably have an outdated baseband.
Thanks for your help,
Sam
It is best to use the same version of baseband, rom and kernel, but they are usually compatible to each other.
The KF4 or KG2 is simply a date-code.
KF4= The 4. release of June(F) 2011(K)
You can flash the odin version (.tar.md5) by putting them in the "phone" field. There are also packages out there that can be flashed with CWM.
You really need to pick a baseband/modem that works well for you some find xxx version works better in the area they are in than a later one .
A rom can be unzipped and the modem extracted and flashed via phone in Odin .

PLEASE READ EDIT BELOW ALSO.CHEERS
Im quite familiar with flashing and odin and flashing kernals and roms via cwm and have done it many times but what ive been noticing lately are people who have modems that dont match their firmware.This is something ive never taken notice of before since i just did the basics.A modem is the country based part as ive found out so heres my question.To have a kg6 with a spanish modem (spain being where i live) do i also have to download my countrys firmware open the kg6 for the csc and kernal files then open the other firmware for the modem?.It just sounds a bit risky although its meant to make the phone function better.Im a bit confused cos when 2.3.4 isnt even global yet ive seen S2 phones with aparrently local modems.Is it possible to use a 2.3.3 modem with 2.3.4 then??....
EDIT:Ive been reading on and seeing that its the baseband that appears to be from 2 firmwares.I have kg6 with a xxkg6 baseband but am seeing others with kg6 and basebands from completely different firmwares?!.So is it possible to mix a 2.3.3 baseband with 2.3.4 cos gingerbread insnt global officially global so how would there be regional basebands.Is it safe and does it improve the phone that much?.Im interested in learning more about it and giving it a try but not without first being a bit more informed.cheers
Any modem can be used with any rom.
I have used modem ranging from ke7 to kh3 on roms from kf2 to kg6.
As far as choosing a modem, try them all, and find one which works best for you, as far as I know modems are not county coded so a kg6 modem is a kg6 modem whatever the country code.
Csc is just mostly apn settings and bundles apps for the region, generally you can use any csc with any rom, but if you have problems most csc's cover most regions.

Thanks.What ive started noticing is that some people that have kg6 like me appear to have 2 firmwares.I saw one person for example that had a Galaxy SGS2-XXKG6-VR 2.4.2-Ninpho 2.0.5 EXACTLY like mine but my baseband is i9100xxkg6 and their baseband was xxkh3.how is that possible if you dont use 2 firmwares and what affect does it have over the operating system.i though this was the local side to it all like local operators and tower conections?how is it done safely?
Firmware version KG6 with Modem version KG1 or KH1 .
Modem is part of original rom package can be flashed separate versions are mostly interchangeable .Custom rom may have different modem version .
Modem file flashed via Odin as PHONE .

Dear members here,
Can i just ask or know if its ok or advisable to flash other region ROM (eg XWLP7)on my SG2 as i am from singapore and baseband version is DXLP9 (ICS) or DXKL3 (GB).
Thanks.
Yes, you can flash a stock rom for another region. You more than likely won't be able to get OTA firmware updates tho if you do. You'd need to re-flash stock firmware for your region in order for those to work again. And even if you do, some people still end up having problems getting OTA firmware updates once they've done so. Which isn't a massive problem as it's easy enough to flash firmware updates for your region via Odin (many people on XDA have done this).
Also, make sure to use a firmware for a model suitable for your phone.
I9100G can only use i9100G firmwares and kernels...
I9100, I9100P, and I9100T can all use each others' firmwares and kernels.
Thanks for all the advise.. i have loaded a baseband of NELP3 and its amazing...
