S2 I9100XXLP6 downgrading problems - Galaxy S II Q&A, Help & Troubleshooting

Hi,
my sister is having a problem trying to downgrade to stock rom after she put a cusom rom (I9100XXPL6) on her phone and is having some issies with it. she didnt take note of some vital information before she flashed it and i think she didnt follow steps properly and she did not backup her phone.
currently her phone says the following when doing *#1234#
Phone bought in UK
PDA: I9100XXLP6
Phone: I9100XXLP6
CSC: Unknown
Build: January 17 2012
she has tried going to stock but it soft bricked her phone so she reflashed her phone with I9100XXLP6 and got it working again, i asked her where she got the rom from and she does not know, the phone was flashed when not rooted etc, as the guide she used said that it didnt have to be done, also she cannot remember what guide she followed.
all i know is that she had 2.3.6 and that her phone was from phones4u in the UK (guessing unbranded) and flashed it though odin (she cannot remember what she done, i guess she had Kies running maybe, i read alot of other posts). i have checked the thread for stock roms but all the links are multiupload which is not longer valid as we know.
i have never flashed a galaxy S2 I9100 and i have never used the phone at all. if anyone knows what stock rom to use and if they can mirror the relevant files it would be appreciated
have looked at [GUIDE] Fix an unflashable or soft bricked GSII but the kernal and bootloader links are multiupload and can only get the recovery package
i have experiance flashing phones and tablets just not the galaxy S2, any help would be apreciated

this is the correct thread for unbranded firmwares

find your UK unbranded FW and flash through ODIN

Search Sammobile to find stock firmware to flash via Odin.

sammobile firmwares all have the correspondent new firmwares bootloaders. so if you flash a FW from sammobile you won't be able to reset the custom binary counter via a Jig. download from Intratech's thread.
oh, and you do not have to follow the soft bricked thread if your phone is working.
just download a FW, put phone in download mode and flash using Odin.

Do what the others have said but make sure you read all the instructions! There are a few howto videos here http://galaxys2root.com/category/galaxy-s2-root/. Just remember your UK phone is the International i9100 model. Good luck.

Thanks for the help, I git the phone back to stock rom

[Q] Vodafone Netherlands Branded SGSII - how to remove?

Earlier in June I received a Galaxy SII that was unbranded, but I had to return it due to a little circle that seemed to be 'burned' into the screen.
Now I finally received my new Galaxy S II but to my great disappointment it's loaded with Vodafone crap, and branded:
PDA:KE5 / PHONE:KE1 / CSC:KE2 (VDF)
I want to replace the branded FW for the official non branded FW and I was wondering how to do that.. I went to this thread but i'm not quite sure which FW i'll need.. Does anyone happen to know?
Use the XEN version of XWKF3 firmware, it's for the Netherlands.
As intratech said flag stock unbranded firmware for your country
You can also try latest 2.3.4 based roms as batista 70, cognition or vilian

Thanks for the quick replies, i'm downloading the Kernel and FW now, but before I get to work with that:
how do i backup the complete kernel/fw of my phone as it is right now, in case I ever have to send it in for repairs and don't want to void my warranty?
Will I be able to update future firmwares with KIES or will i have to keep doing it manually once I install the unbranded firmware?
After flashing the XWKF3 XEN firmware on my phone instructions say i need to flash the insecure kernel before i can flash the stock XWKF3 kernel. I was wondering which Chainfire version I have to get. I think it's the KF3 one from this post but I'd like to make very sure before I start doing things.
Then after flashing the Chainfire kf3 kernel I can use Odin in the same way to flash the stock KF3 kernel, correct?
Once all this is done, will KIES recognise my phone and offer me updates when they become available or will i have to keep doing it manually?
Is it possible to backup my current FW/Kernel with Odin so that I can put those back on in case I ever need to return my phone for repairs and don't want to get any trouble with warranty?

[Q] i9100xxKP8 busted my phone

Hi everyone,
This is my first time and I am wondering if someone can help. I have tried everything and nothings far.
I have SG SII few weeks ago someone mentioned that ICS was out so I googled it and followed the instructions which installed i9100xxKP8 4.0.3 version and at the first start the phone does not recognise any SIM card you put. I know I made the mistake not noted down the original firmware number etc.. But I am stuck I can't use Kies to upgrade to the proper O2 upgrade which is out.
I had a look at SamMobile.com and I would not see any firmware or instructions.
Any help would be appreciate it before I bin this lovely phone .
Thank you
Wessam
Can you see your imei number?
Sent from my GT-I9100 using xda premium
The O2 UK ICS firmware is on XDA flashable voa Odin not KIES .
jje
No need to bin it if you can boot the phone into download mode. Can you?
And the firmware hasn't "busted my phone" - you did.
Why are you trying to flash some old beta version of ICS into your phone when there are much newer and official versions available such as xxlpq, xwlp7 etc? Just follow the instructions how to flash those firmwares from here: http://forum.xda-developers.com/showthread.php?t=1544487

Could someone please post the download for the correct stock rom for my phone, and also tell the process for restoring the stock rom to my rooted phone.
Thank you so much

Hello,
go to sammobile, search for your device. Select your country and provider even Gingerbread 2.3.6 or ICS 4.0.3. download Odin 1.85 too.
Unzip the downloaded file. You get a .tar file.
If you flash the .tar file (select PDA in Odin 1.85)you will return to stock and the phone will even be unrooted.

Stock Galaxy s2

Hi so I'm trying to get my galaxy s2 back on stock firmwares, I just changed to gingerbread XWKI4 but now it won't update via kies.
Does anyone know why that would happen? Or what the official unbranded UK version of ICS is?
1. wrong forum
2. select your csc and try again

If you know which stock firmware you want to go back to then you can just download the firmware from Intratech's thread and use odin to flash it. All the instructions and downloads can be found on this thread, read it carefully ..
http://forum.xda-developers.com/showthread.php?t=1075278
If you want to flash official unbranded UK ICS release then use Faryaab's Thread and flash the I9100XWLP7 ROM using Odin, the ROM can be downloaded from the 2nd post. Again follow the insturctions in the first post carefully.
http://forum.xda-developers.com/showthread.php?t=1544487
If you flash the unbranded UK ICS rom mentioned above and, as long as your phone is also unbranded, then Kies should detect your phone's firmware again. It stopped detecting it because you changed to a ROM that was not intended for your phone.

Official Branded Kernel/ROM

Hello,
I'm attempting to return my I9100 to stock so I can update via KIES as I wish to sell it, after rooting, flashing ICS, playing around for a month etc...
It was originally a T-mobile handset, I used checkfus to find the original stock ROM, and I've downloaded it, however, I cannot get hold of the stock kernel for love nor money! (I've googled it, found one apparent alternative source, but for some reason it wont boot using this and just keeps looping through the T-mobile branded load-up screen)
The kernel I'm after is the following:
UK
BOKE3:http://www.multiupload.com/GY05UJM6DQ
Firmware info: PDA:BOKE3|PHONE:BOKD1|CSC:TMUKE3
BOKE3 Stock Kernel: http://www.multiupload.com/I41CAJ2BLS

[ROMS]Official i9100 carrier branded firmware download for Odin Flash
http://forum.xda-developers.com/showthread.php?t=1113928
I've read the thread and checked both Sammobile and Samsung-update and neither has the BOKE3 Kernel.
If anyone has this, please, please could you upload it so I can return my handset to stock, I would really appreciate it.
Also, if I'm doing anything obviously wrong, please point me in the right direction, I am a n00b at this. (I've successfully reset my counter using triangle away, and flashed the ROM from checkfus, but KIES still says NO!)
Many thanks!
Luke
ps. I realise now I should have backed up my stock kernel and ROM before tweaking, stupid stupid stupid...
I stopped reading somewhere when you say you downloaded using checkfuS and now after a stock kernel.........
Buddy ROM package like you get from checkfus is whole thing including kernel.
Just flash the ROM using Odin.
But be sure its for i9100 if you have that.

Why don't you just download and flash latest ICS ROM with UK support?
Do you really need the branded version?
Just have a look at Intratech's other thread => http://forum.xda-developers.com/showthread.php?t=1075278
I recommend XWLPD, as this has best balance between performance and battery life on my phone.
If you want to go bak to GB, then flash XWLA4, which was best GB ROM IMO.
Thank you so much atifsh!
I did wonder whether the firmware download from CheckFus included the kernel, but couldn't figure it out (I'm stupid, I know! I'm new at this stuff...)
It's definitely the i9100 (checked under battery), it's definitely a T-mobile UK handset (bought it from a T-mobile customer who provided the contract paperwork).
Last night I tried flashing the latest T-mobile firmware, but KIES didn't like it, so tried flashing the BOKE3 firmware (oldest T-mobile branded firmware) and it didn't like that either.
Someone mentioned that when flashing you need to add the firmware file to the CSC section of odin to reset the CSC code, is this correct? I normally only include it in the PDA section.
This may be the problem I'm having as when I check my CSC using *#272*IMEI# it only lists CPW (carphone warehouse) and not TMU (T-mobile). Does this make sense as to why KIES wouldn't recognise the firmware?
I really appreciate your input and help here. Many thanks!
Luke
Hi It_ler,
Thanks for the advice, I was running the latest ICS firmware from the official thread, however I've decided to sell the device and would like to restore it to stock so that whomever I sell it to can update it through the official methods if they so wish.
Hope that makes sense!
Luke
Remove Sim, remove external sdcard.
Put the firmware.md5 in pda
Put your phone in download mode
after flash and boot dial *2767*3855#
It will wipe your phone and hopefully fix your csc.
Atifsh,
Thank you SO much! You saved my bacon. It worked when I did the *2767*3855# reset, this fixed the CSC and then the phone could update via KIES.
I really appreciate you help,
Many thanks,
Luke
