Hello guys, i currently have an o2 unlocked sgs2 using vodafone sim. i would like to debrand, root and flash the latest firmware.
if i debrand will that mean i can flash the stock firmware?
and also what is the correct order to carry out these 3 things?
AS per the debrand post in dev section .

Branding makes no difference debranding is flashing a stock firmware
Debrand or Update root flash latest kernel is the order .

Hello All, I have a few questions which I hope to get answered here in this great forum.
I have T-Mobile UK loacked and branded SGS2. The Firmware info which is get by pressing *#1234# is
Code:
PDA : I9100BOKE3
PHONE : I9100BOKD1
CSC : I9100TMUKE3
I have tried to update the software from Settings > About phone > Software update but it never connects to the server hence I stopped trying. Now I have following questions:
===============================================================================
Question 1. Rooting.
===============================================================================
I have read the thread --[17.08.2011][CF-Root v4.1] KE2/7/8, KF1/2/3/4, KG1/2/3/5/6/7, KH1/3 - su+bb+CWM4-- None of the rooted kernals (zip file) match my kernal which in my case is KE3.
Do I have to flash a different version of fimware/kernel before rebooting?
If yes,
Can I use latest generic UK firmware
Code:
XWKF3
PDA:XWKF3
PHONE: XXKE7
Build date: 09/06/2011
provided in thread --[ROM + Guide]Official i9100 Firmwares KF1/2/3/4/, KG1/2/3/5/6/7, KH1/3 Download--
There are two files under this firmware which relate to my phone
XEU (Generic UK+Europe) and XWKF3 Stock Kernel
Which one of these files do I need to flash.
If No,
Then what else do I have to do===============================================================================
Question 2. Unlocking.
===============================================================================
After I have rooted the device I intend to unlock it. Odia has mentioned in his thread --[HOWTO] GT-I9100 Free SIM Unlock via nv_data.bin by Odia-- that the unlock method only works for
HW Version MP 1.200 and further in post 284 He says
Samsung have now moved to the new simlock protection across the GT-I9100 range even MP 1.200 hardware has it @ least from KG1.

Click to collapse
Will I be able to unlock if I have the latest UK firmware XWKF3 mentioned in question 1?
How do I check Hadware version of my SGS2
===============================================================================
Question 3. Debranding.
===============================================================================
As my phone T-Mobile branded, I want to de-brand it.
jutley has provided a method to de-brand O2 branded SGS2 in his thread -[GUIDE] Debrand & Rebrand back to O2 for Samsung Galaxy S2-.
So if I use XWKF3 UK generic firmware during rooting and change CSC will it de-brand my phone too or I have to use the earlist UK firmware for de-branding.
===============================================================================
Question 4. Future Updates.
===============================================================================
Do I have to keep using flash method to update the firmware or I can use KIES.
===============================================================================
Question 5. Resetting Flash counter.
===============================================================================
I have heard that there is some counter in SGS2 to track how many times the phone has been flashed.
I have read about USB jig on internet that automatically resets the flash count.
Is there any mod I can do to accomplish this without usinf USB jig.
I hope I have explained all my questions properly and await positive reply.

Hi,
I have a T-Mobile SGS2 and I downloaded Keis and it updated my phone to KF3, I then found the rooted kernel for T-Mobile KF3 and flashed that using Odin. (it's in the link posted above)
Now I can have backlight notification installed but I've probably bust my warranty.
Well, yes if you root then bang goes your warranty. Do you have a yellow triangle with a ! symbol when you boot the phone? That's shows you have installed a custom rom, and have more than likely voided your warranty.
But don't worry! Just flash an official firmware from the thread above and your SGS2 is back to it's original form and your warranty is intact.

So I have 1 question answered:
To root my device I can upgrade my firmware to KF3 using Kies and then root my device using Chainfire's CF-Root v4.1.
Can you confirm that I can still unlock the device after update?
I had apple iPhone 4 and by mistake I updated it to latest firmware which makes unlocking impossible because I can't revert the firmware back anymore.
Do we have the same issue with SGS2

I paid for my unlock code from T-Mobile so I could use my O2 SIM (Long story). After the kernel flash to root the device it still worked with my O2 SIM.
I should have rooted it first (Hindsight is wodnderful!) and then run the unlock App, OH Well.
Hi, I just got a new Galaxy S2 but it is locked to O2 and is O2 firmware branded.
I don't mind wiping all data (since there's nothing on it yet), but is there a way I can change the firmware to the original Galaxy S2 firmware?
Or what is fastest?
I don't like all the preinstalled junk that has come with the phone, I'm not bothered about unlocking it since I'm using O2 anyway.

Flash a uk rom from here. I'm personally using KH3 with XEU CSC
Locked then you need to get it unlocked .
Debrand O2 in Dev section as well .
jje
Do I need to unlock it before I put the stock firmware on?
To unlock you need to root (use cf-root) then download chainfires unlock app from the market (may not work on newer sgs2's due to them being more secure)
You dont need to be rooted or unlocked to flash a newer stock firmware, there is a fully guide and list of firmwares to download from this thread, using any firmware from there will debrand the phone, try KG6 (older) or KH3 (newer) both are good 2.3.4 roms.
hi i am currently, according to Kies, using the latest version available to me on my Galaxy S2 (i9100) which is unlocked and i bought from the carphone warehouse.
The fimware I am using is 2.3.4 and my Kernel is 2.6.35.7-I9100XWKI4-CL575468
PDA:KI4 / PHONE:KI1 / CSC: KH1 (CPW)
however i know that this isn't the latest official release for the UK. I have researched numerous threads and i have tried changing me CSC using #*272*IMEI# however i am locked to CPW. So i then did more research and have found that i need to debrand my galaxy s2 from CPW to XEU to get the latest generic unlocked UK firmware. Can someone please tell me how to do this without using #*272*IMEI# because that doesn't work?
Your phone is unlocked but you want to unlock it ???
CPW is about the best CSC for the UK as it covers more networks ..
You will not get an update via KIES by changing your CSC ..
You can update and debrand by flashing a stock rom from the stock rom thread but you will may lose the KIES update path from then on.

yes but if i remain on CPW i will stay on android 2.3.4 where as if i switch to XEU i get the latest updates since it is the most generic UK firmware? and surely if i change my CSC then Kies will offer me an update to 2.3.6

CSC has nothing to do with updates .
KIES reads the firmware and hardware and vendor codes from the phone .
Two paths to updates official via KIES you wait for vendor release
Or XDA via ODIN using latest stock Samsung firmware
Third possible is to use CheckFus to download firmware or find a way to change the codes on the phone .

okay well howcome if i have unlocked handset i am still on 2.3.4 when there are people in the UK with 2.3.5? (sorry i am a noob)

You have a set of codes on your phone that determine its vendor and ID etc
Kies reads those codes
O2UK xxxx O2UK 11xxxx etc etc .
Then looks for that firmware on the server if it matches it downloads if it does not match it cannot download . So unless the vendor has updated then you have no download . Its the phone vendor who updates .
CheckFus and SpoofFW are two roous that may bypass the Kies checkup .
http://forum.xda-developers.com/showthread.php?t=1318683&highlight=spooffw
But this is XDA Developers and we dont use KIES .

okay how do i know who my phone vendor is? i think it would be easier for me to just install cyanogenmod 7.1 however i am having trouble because when i followed all the instructions, i successfully rooted my phone installed ROM manager. however when i installed clockwork recovery and rebooted my phone it loaded android recovery mode 3e and says signature verification required. i gave up after a few attempts and thought it was due to my kernel? does the kernel version affect cyanogenmod? i.e. do newer versions of CM require a newer kernel?
You have Carphone Warehouse CSC hence no updates as most carriers tend to provide the updates.
Root with CF-ROOT and use customs or just flash a different firmware newer version with uk CSC with ODIN.
Sent from the valley of the shadows....
how do i CF-Root? and cant i just change my CSC so i get the newer updates if cpw doesn't release any?
No for reasons jje already said.
CF-ROOT is in original development and has concise instructions its very simple
There are lot's if stickys too take some timeout and read up as most information there will help you regarding learning about device.
Sent from the valley of the shadows....
okay then can you answer to questions for me? does a newer kernel affect the cyanogen mod and can you tell me how to install CM7.1 using CF root seeing as it didn't work last time due to signature error?
bomskiboy said:

Do you mean can you put another kernel in CM a rom that already has a kernel
and can you tell me how to install CM7.1 using CF root seeing as it didn't work last time due to signature error
The instructions are on the first page .

First time flashing CyanogenMod 7 to the Samsung Galaxy S II, or coming from another ROM?
Root the device and install ClockworkMod Recovery.
http://forum.xda-developers.com/showthread.php?t=1103399
Perform a NANDroid backup of your current ROM.
Copy rom to internal SD card .
Format the system, data & cache partitions of your device via mounts and storage recover
Perform a factory reset.
Flash CyanogenMod.
Flash CM a second time .

first time and does whatever kernel you currently are on affect CM mod? or does CM install a new mod?
BTW 2.3.4 is the latest XEU firmware so changing to this won't make any difference to your firmware version number.

Hey guys.
I just received a TRE (Three) Italy branded GSG 2 with the following PDA, PHONE and CSC info here:
PDA : I9100 XWKI8
PHONE : I9100 NEKI2
CSC : I9100 HUIKI1
If I install the XWKI8 Stock Kernel from here, using ODIN, will that work ? I want the same version of software, but with NO BRANDING.
Afterwards I want to upgrade my phone to ICS, but I just want to get rid of the 3 (Three) icons and bootscreen first.. Afterwards If I want to go back to the 3 (Three) version if I install the one with the info above will it work ?
Thanks a lot guys.
Stock answer is read the debranding post .

No as you dont have a clue and need to read the Faqs and Guides first .
Kernels are not firmware you require full firmware . Read the thread instructions .

Q
Okay. Got it. read them. Ty JJe.
So from what I've read I understand that I can install whatever firmware that is available here, under the OFFICIAL FIRMWARE section, the original and current firmware that I've got being available here, under the 3 Network, under Italy.
Can I install _ANY_ firmware ? Or any other one that has the same PDA version (XWKI8) ?
Afterwards.. If I want to go back to the original FW the phone had, is flashing the firmware version above, under the 3 network, Italy everything I have to do ? If for example I've got a problem with the phone or software and want to use its warranty. Ty.
Thanks all.

As JJEgan told you, you can flash any firmware. Just a suggestion: After you change the firmware, reflash the NEKI2 modem. It's one of the best for 3 in italy
Hello,
can i flash an image from a different provider? my current firmware is the official Cosmote - Romania firmware, will it work if i flash the official Vodafone - Romania firmware?
Will this modify the internal counter?

if you are rooted you should be able to flash anything, whereas the question is more do you want a branded ROM?
if you are not rooted, I assume you can't but please correct me if I am wrong.

Yes any stock or provider rom can be flashed via Odin .
You do not need root at all .
Use CHECKFUS to download any current stock /provider rom and flash via Odin .
This does not touch your rom counter .
