First post updated with working download links.
[Galaxy S II Themes and Apps] bigmo7:
CSC is country specific code. It includes settings for data over the network providers and things like that.
[Galaxy S II Themes and Apps] sleeco:
Thanks for the easy way to debrand, all went well, the German confused me for a min, all working now to root.
[Galaxy S II Themes and Apps] hshah:
Rather than doing this, can't I just put my own boot and shutdown screens on?
[Galaxy S II Themes and Apps] jonrwg:
This will void my O2 warranty? Any way on how to restore to O2 firmware?
[Galaxy S II Themes and Apps] robot1000:
I've asked this exact same question on another forum and the response I got was that you the O2 Firmware would need to be reflashed and at this moment in time it has not been leaked.
[Galaxy S II Themes and Apps] kersey:
After debranding, I need to apply Chainfire's unsecure kernel and then SuperOneClick to root, but if I then reflash the kernel contained in the first post (CODE_I9100XWKDF_CL170898_REV02_user_low_ship.tar.m d5) to get rid of the yellow exclaimation mark does the root still work or do I need to stay on Chainfire's kernel to stay rooted.
[Galaxy S II Themes and Apps] bigmo7:
I think you'll lose root if you flash that...
[Galaxy S II Themes and Apps] jamesking420:
Incorrect. You will KEEP ROOT if you flash a kernel back
[Galaxy S II Themes and Apps] JJEgan:
You need to have saved the O2 firmware . It wont get leaked it may be saved by a user and uploaded .

Thanks, my phone just arrived this morning and this is the first thing I have done :D
[Galaxy S II Themes and Apps] AaronUK:
Will this remove my 02U CSC ?
[Galaxy S II Themes and Apps] jutley:
yep if you do step 8
[Galaxy S II Themes and Apps] AaronUK:
Thanks. Will give this a try.

To get rid of the yellow /!\ I need to flash a different kernel. Are there any disadvantages to this and where can I find instructions?

Thanks again.
[Galaxy S II Themes and Apps] BailA78:
Hi,my Galaxy S2 is original UK.I flashed forum Samfirmware this :

I flashed again your firmware

but i dont have XEU csc and Kies says I can not update.

How to fix?

Sorry for my bad english
[Galaxy S II Themes and Apps] jutley:
The phone has changed it's CSC, but the ProductCode stored within the phone is still set to something different (DBT, which is Germany / Austria, and the default for the KDF firmware). To change this, you'll need to edit the nv_data.bin file, or wait for a multi-CSC firmware to become available. (I'd wait if you're not sure what nv_data.bin does or how to change it)
[Galaxy S II Themes and Apps] BailA78:
thanks for the quick reply, look for firmware fix
[Galaxy S II Themes and Apps] jameslfc5:
Hi all,

Just wondering if this will void the warranty in any way ? :)

Thanks OP!
[Galaxy S II Themes and Apps] jutley:
yes it will cause the o2 logo will be removed
[Galaxy S II Themes and Apps] jameslfc5:
So it isn't really worth doing then is it? :/

Some people have received their phones from o2 unlocked without splash-screens though ?
[Galaxy S II Themes and Apps] JJEgan:

[Galaxy S II Themes and Apps] jutley:
I am going to do a rebrand guide back to O2 stock soon just waiting to get my hands on the O2 stock rom whack I believe has been done and ready for uploading.
[Galaxy S II Themes and Apps] JJEgan:
SGS and original O2 rom was just flash as PDA via Odin .

[Galaxy S II Themes and Apps] Fornowagain:
Here you go, O2 stock firmware decrypted > http://www.multiupload.com/VHX20NJEAP
[Galaxy S II Themes and Apps] mb:
Sorry to moan but you need to make your instructions clearer - especially what you select in Odin. I got into a real mess trying to replicate your picture, which is wrong. Can you upload one which is exactly right?

Instructions especially for Step 5 are a mess. You only need to tick and fill out the PDA section.

And Step 6 is also wrong. It's irrelevant which COM port number is showing in Odin (I had COM11 for example), it just needs to be there and yellow.
[Galaxy S II Themes and Apps] jutley:
Done will upload a pic soon
[Galaxy S II Themes and Apps] mb:
Thank you! I felt bad having a pop at you, nothing personal. Is the firmware in the first post still the very latest?
[Galaxy S II Themes and Apps] jutley:
Yes it is i will update the firmware as and when a new one comes out and the guide if it requires a different method. just uploading the corect pic with the settings now.
[Galaxy S II Themes and Apps] nikzDHD:
Thanks for the guide mate, going to finally debrand :)
[Galaxy S II Themes and Apps] jutley:
Guide updated updated the pic as to how the setting should be and what file to load and cleared up a few instructions to make it abit simple hope it helps.
[Galaxy S II Themes and Apps] iOStoAndroid:
Thanks

Just done it on my replacement Galaxy S2 (the first one had a defective back button)

I had to to wipe all data to get CSC:XEUKD1 (XEU csc), reboot did not do it.

A small difference I noted is that now Swype option for Audio Feedback is selectable (I prefer this to vibration)

NB Had a desire previously and it's so much easier on the Galaxy S2
[Galaxy S II Themes and Apps] Beefheart:
So other than removing the O2 splash screen on bootup/shutdown there is no real advantage to this? I will give it a miss for now then as my phone is already on KDD and is never turned off. But if a newer firmware with advantages appears and upgrading an O2 branded phone through official means isn't possible I will then dive in.
[Galaxy S II Themes and Apps] clarkgable:
is there anywhere else other than hotfiles that you can get the samsung unbranded firmware from? hotfiles is awful slow for me.
[Galaxy S II Themes and Apps] JJEgan:
Samsung unbranded firmware stockists samfirmware.com

But they are on hotfile .

jje
[Galaxy S II Themes and Apps] snoopstah:
Many thanks -- great to know we can revert to the O2 firmware should we need to.
[Galaxy S II Themes and Apps] StarmanUK:
Any chance someone could put 9100XWKDD_I9100XXKDH_I9100XEUKD1.zip on a different site as I find hotfile VERY slow ~3.1KB/s atm.
[Galaxy S II Themes and Apps] pulser_g2:
I have it on my server. Will post a link tomorrow as it's not in a web accessible folder right now. That is the stock o2 one you are after? Or is it the unbranded one you want?
[Galaxy S II Themes and Apps] mb:
Massive improvement on what I was trying to follow earlier today! Thanks for making it easier to understand.

To all those people thinking about switching, I would say the biggest thing to bear in mind is FUTURE updates. If your handset is "locked" (in the flash sense) to O2, then it's quite likely that you will not be able to find any updates to download for the forseeable future. My guess is that by making it generic, you stand a better chance of updates from Samsung.
[Galaxy S II Themes and Apps] robot1000:
Just followed your very informative guide, but I can't seem to get rid of the 'Sales Code' showing as 'O2U'. I've done multiple factory resets, but that hasn't got rid of it.

Any ideas?

Edit

I've just checked on KIES and my 'Current Firmware Version' is blank

I'm starting to get worried now :confused:
[Galaxy S II Themes and Apps] jutley:
Reinstall firmware again
[Galaxy S II Themes and Apps] StarmanUK:
I downloaded the O2 stock file fine as it was via multiupload which had a range of sites to choose from. I'm just after the Unbranded f/w.

Thanks in advance.
[Galaxy S II Themes and Apps] robot1000:
Makes no difference
[Galaxy S II Themes and Apps] pulser_g2:
Done. Posted them at this link so if they get heavily used, I can turn on mirroring of them.
[Galaxy S II Themes and Apps] Beefheart:
Does it need to be Odin 1.83? I used 1.85 to flash root yesterday.

EDIT - Ignore that, I did it anyway and it all went fine. Just need to reapply root now. Cheers.
[Galaxy S II Themes and Apps] S1MB4D:
Might sound stupid but still....

yes this might dumb but is there no other way of removing the dumbass startup and shutdown logo other than installing firmware?
[Galaxy S II Themes and Apps] pulser_g2:
I will try and get something out tomorrow evening that does this without a full flash.

Will need root though
[Galaxy S II Themes and Apps] S1MB4D:
fantastic!

I got my phone from 3. Thus, my ROM is 3 branded. Is there a copy of the stock 3 rom anywhere, alternatively is there a way for me to extract it from my device or otherwise obtain it?
[Galaxy S II Themes and Apps] zen123:
Hi your link for the rom is broken.
[Galaxy S II Themes and Apps] Fornowagain:
Connect it to Kies and get the info below from regedit, might be possible to get the 3 firmware.
[Galaxy S II Themes and Apps] pulser_g2:
Both links working fine here

What do I do next???
[Galaxy S II Themes and Apps] Fornowagain:
Take the info and look here > http://fus.nanzen.se/

If Samsung server responds then the firmware can be downloaded and decrypted.

Sorry checked and it looks like you're out of luck, try later it may appear at some point.
[Galaxy S II Themes and Apps] anti-derivative:
hey, that's good to know though... is there any way to extract it from the device?

And this wouldn't affect compatibility with any of the stuff already on here would it?
[Galaxy S II Themes and Apps] Fornowagain:
Not easily and certainly not straight forward. Keep looking for a 3 firmware to download, if only for warranty reasons. They'll update eventually.

The 3 bit and pieces is only branding, doesn't effect anything.
[Galaxy S II Themes and Apps] anti-derivative:
ah so this little program basically pretends to be kies accepting an official firmware update by submitting the info above to samsung's servers. Thus, this program intercepts that update and allows me to save it. That makes sense. Hope 3 update soon then.
[Galaxy S II Themes and Apps] Fornowagain:
Not quite just updates, but the most 'up to date' as it were. From playing with it, if there's only one that's all you get, if there's a few older ones you get the latest.
[Galaxy S II Themes and Apps] jester27:
Sorry just tried to get the unbranded one and it fails...

The O2 version comes down ok.

Help reverting back to o2

I need to send back my phone to O2 tomorrow and I've tried flashing their firmware 'I9100XWKDD_I9100XXKDH_I9100O2UKD1_HOME', but I'm still getting the Samsung startup screen

Can anyone help?
[Galaxy S II Themes and Apps] markdyer72:
if i was to unbrand my SGS2 would all my apps still b there or would it b like it came straight from the factory, as in i would neded to re-install everything.
[Galaxy S II Themes and Apps] winwiz:
its gonna wipe it buddy
[Galaxy S II Themes and Apps] markdyer72:
cheers for that, thought that would b the case, i have only had my fone since 3rd may i got it so havent got too many apps on to replace, i'll just make a note ov them and re-install once de-branded :D, luckily i have no paid apps yet lol
[Galaxy S II Themes and Apps] eXecu7or:
Wonderful, XEU CSC and no branding. Thanks, mate!
[Galaxy S II Themes and Apps] markdyer72:
ahh my SGS2 is o2 branded altho it is not network locked as have tried other sim cards that work, it has the o2 flash screens, and have just connected to kies and is currently updating the firmware, so i guess o2 are not delaying any updates.... my worst experience with that was with orange when i had HTC Touch HD, to get the latest roms i had to unlock/debrand and re-flash the rom
[Galaxy S II Themes and Apps] Beefheart:
That's a bit worrying. Then again, I'd just claim ignorance and say you know nothing about it. Did you reset the counter and get rid of the triangle with a jig? If so I doubt they would refuse to fix or replace it (assuming that's why you're sending it back).
[Galaxy S II Themes and Apps] tready:
Iv just used your guide to debrand my branded network 3 sgs 2 worked gr8 thanks just hope i dont need to send it bk lol as there no 3 firmwear yet
[Galaxy S II Themes and Apps] Fei_Fong_Wong:

Thanks in advance
[Galaxy S II Themes and Apps] markdyer72:
I got my sgs2 on upgrade from o2 and apart from the splash screens its unlocked as I have tried an orange sim in and seemed to work fine.

Will b debranding very soon mind have already downloaded the necessary files
[Galaxy S II Themes and Apps] JJEgan:
Locked O2 wait until you get it as it will probably be unlocked .

Will b debranding very soon mind have already downloaded the necessary files

Rebranding mine as i prefer the O2 splash screen and hey its genuine hacked O2 firmware or looks like .

[Galaxy S II Themes and Apps] pixie77:
Just received my S2 on o2 contract but it is sim lock, tried my Voda sim and it asks for a pin. If I flash the latest multi csc firmware will this unlock my phone.

Many Thanks.

EDIT

As I thought somewhere at the back of my mind flashing the XEU multi csc firmware over the branded o2 software does not remove the sim lock (as most of you probably new)

What it has done is changed my O2U csc to XEU. As it says in another post, after the first flash of XEU firmware Kies still thought I had an O2U csc, I then did a factory reset now Kies sees my phone as XEU. It also needed the factory reset to remove all of the o2 customisation.

I'm now waiting for my sim unlock code from mobileunlocked.co.uk (please don't tell me this can be done as quick for free as I may cry!)

Happy days I hope
[Galaxy S II Themes and Apps] markdyer72:
AFAIK it wont make it sim free....

to check the locks try this code:

*#7465625#

Personalization status:

Network lock

[OFF]

Network Subset Lock

[OFF]

SP Lock

[OFF]

CP Lock

[OFF]

and this is from my SGS2 that i got on upgrade from o2 on 3/05/11

hey just wondering how did you get o2 to give you the code as they are saying it has to be used for at least 1 year on their network.
[Galaxy S II Themes and Apps] markdyer72:
i just filled the form in then got email back saying has been passed to relevant dept and then 2 mins later got another email quoted below...

Hello Mark

Thanks for your email.

I understand you want to get your phone unlocked. I've placed the

request from my end and it'll be unlocked within 5 working days.

Then you can put any non O2 SIM card in your phone and start using it on

other networks.

If there's anything else I can help you with, please let me know.

Will this mean that I can use this to flash back the 3 factory ROM if necessary?

EDIT: when I try to open the .enc.zip file, windows says it is 'invalid or corrupted' is this normal? Is it not a typical windows built-in-zip (ie: i'm not using winzip or whatever) compatible type zip file?

Network/Sim Unlocking on Samsung Galaxy S 2 i9100

Hello Genius,

Could you please help me with the step by step procedure to SIM unlock my Vodafone Samsung Galaxy S 2 i9100 . Also let me know if there is a procedure to re-lock the network in order to avoid warranty issues.

Thanks in advance.
[Galaxy S II Themes and Apps] Bawezy:
I would also like to know more info on this. Please advise.

This isn't an unlocking thread buddy. Unlock and debrand isn't the same thing. If you are one of the buyers that have bought it from Samsung's first batch of their supplied phones, then it's highly likely it is network unlocked already :)
[Galaxy S II Themes and Apps] markdyer72:
well just updated again via kies to PDA:KE7 / PHONE:KE4 / CSC:KD1 (XEU)

and is now definitely unlocked, have just put son's orange sim in and made calls/txts :D, lets just hope never have need to return it, altho i have kept copy original o2 firmware for emergencies :D
[Galaxy S II Themes and Apps] cbailey:
Would this work for a Vodafone handset?
[Galaxy S II Themes and Apps] markdyer72:
are u referring to de-branding via the instructions in post #1, if so then yes i do believe it works on any network fone as all it does is replaces the branded firmware with de-branded firmware, please not it does not makje your handset unlocked....
[Galaxy S II Themes and Apps] cbailey:
Yes exactly Mark. I want to know if I buy a voda handset, I can take all the 'junk' off by this method :)
[Galaxy S II Themes and Apps] markdyer72:
in that case then yes u sure can, as the firmware in the 1st post is normal uk samsung un-branded firmware that u would get on a handset had u bought it sim free....

once u have installed the firmware in post #1 then just connect to kies and it will automatically update it to the latest firmware....

make sure u dont forget step 8 regarding the CSC :D
[Galaxy S II Themes and Apps] Bawezy:
Mark this firmware doesn't have any influence on the network lock as that is a seperate encryption. Your device was most likely unlocked already. This0 firmware only removes all the orange branding to make it look as if it was bought via carphonewarehouse or phones4u, where they sell unlocked handsets because it isn't network tied.

EDIT: Although as you may have heard that NFC is coming to Orange so they'll be modifying their firmware so that the phone would support NFC and most likely provide NFC based simcards. So I wouldn't have suggested a debranding for you as you may have been lucky to stay on orange firmware.
[Galaxy S II Themes and Apps] markdyer72:
yeah i know, and yes it was unlocked when got it and was from O2 direct on upgrade, i also filled in the unlock form on the o2 site just to b doubly sure, and yes it is now as it would b if bought from CPWH, which is where i usually by mosta my fones as CPWH do not sim lock or brand there fones, if u buy it on any network u get exactly the same fone...:D, which is y i normally buy them on orange from there cos they tend to b cheapest then just pop my o2 sim in :D
[Galaxy S II Themes and Apps] Bawezy:
Lol well lucky you, O2 users get most of the support everywhere. I really hate 3's service :( Although they provide deadly cheap deals, I'm paying £25 per month for mine from launch day. Lol that's really what's got me tied to them. And speaking of 3, I can't find 3 UK ROM for the GS2 anywhere :( you lucky O2 users.
[Galaxy S II Themes and Apps] JJEgan:
Well unless you save a 3 rom or another use does then it does not exist in the wild . That goes for all network firmwares nobody ( well nearly 0 saves them so no supply .

Save is via Kies download lightning fast copy from C/Temp folder as soon as download finishes before update starts .

jje
[Galaxy S II Themes and Apps] anti-derivative:
I think I was able to get the latest 3 firmware using the little program on:

http://fus.nanzen.se/

The relevant parameters were found in the registry after installing and linking Kies with my handset. You should probably check your own at

HKEY_CURRENT_USER\Software\Samsung\Kies\DeviceDB\1

Model = GT-I9100

Product code = GT-I9100LKAH3G

HIDSWVER = I9100XWKE1/I9100H3GKD4/I9100NEKD5/I9100XWKE1

The CSC for 3 is 'H3G' as you can see from the last three characters in the Product code.

The first time I downloaded I got a corrupt zip, second time I got a working one. However I have not tried to flash what was downloaded on to my device, and I am not certain that this method described above is complete. Perhaps someone experienced in these matters can chime in.
[Galaxy S II Themes and Apps] Borg3D5:
Hi there :)

I no need to debrand my phone, i just need to change my firmware with a more cool one from the stoks, so my question is:

Can i flash the Uk firmware at the top of this tread (the one used to de-brand the phone) if mine is this one :

PDA I9100XWKE2

PHONE I9100XXKDJ

CSC I9100XXKE2

P.S.

My phone is no brand
