[Q] Need help resetting my phone to original - Galaxy S II Q&A, Help & Troubleshooting

Hi
I have tried searching for the answer but i can't find a guide that is easy enough for me to understand.
I have flashed my phone with Lightening ROM and now I want to go back to the way the phone was before when i bought it. Without custom ROM og KERNEL.
Can anyone please help me with this?

I don't know how your phone was when you bought it, but it's likely it was running a ROM from either [ROM+Guide]Official i9100 Firmwares KG, KH1/2/3/4, KI1/2/3/4/8, KJ1/2 Download or [ROMS]Official i9100 carrier branded firmware download for Odin Flash.
The first thread includes full instructions.

[Q] Problem upgrading from KI4 2.3.4 to KI3 Android 2.3.5

Hi,
I am currently using KI4 Android 2.3.4 and I want to upgrade to KI3 2.3.5.
I downloaded the firmware (but I think it was simply the stock kernel) from Intratech's post - "XXKI3 stock" and I flashed it using Odin, but it got me into a boot loop and thankfully I did a back up before in CWM4, but I had to re-install KI4, root it, go back into CWM4 to restore the phone. Again thankfully that worked otherwise I would have lost everything.
So... how should I be doing the firmware upgrade?
Also, should I download ZSKI3 instead of XXKI3? I know XX belongs to Europe, but where does ZS belong to? Does it even matter where it belongs to?
Lastly, if I decide not to use CyanogenMod, and I want to use another ROM or if I want to just simply use the stock version that came with the phone, what should I do?
Follow the instructions . Stock firmware thread .

FULL FIRMWARE NOT KERNEL
ZS = China HK firmware .
Lastly, if I decide not to use CyanogenMod, and I want to use another ROM or if I want to just simply use the stock version that came with the phone, what should I do?
Dont make sense to me but if you want to use a rom you follow the given instructions likewise a stock rom read and follow the instructions .

Thanks JJe!
I have another simple question, is there any problem with installing ROM on different firmwares? Because as I look in the forum, I have seen the ROMs having based on KI4, KI3 and so on... is it critical that I upgrade the firmware, then install the ROM?

No mostly is the answer rom modem kernel interchangeable in practice .
My preference if KI3 custom rom would be to install KI3 stock beforehand .

[Q] New S II. Bootloop after flashing theme

I got a new S2. Its GSM from Germany. I tried to flash an ICS Theme. But now i got bootloops. I tried to Wipe everything but it doesnt work. I am able to use Odin or Kies. Can somone help me to bring it back to where it was original. without any theme and no root? i got Odin and Kies installed. Where do i get Stock Rom for 1und1 Germany or Stock German rom and how do i install it?
which is the right firmware to download. i dont get it which one is the right one and which one is the newest to use for german language
i got these information from my rom XXKI4, KJ1
Get carrier-specific firmware here or if your carrier isn't listed in that thread get country-specific firmware here. You could also use Checkfus (do a search on here) to get the latest firmware available for your carrier that you'd normally get via Kies.
thanks a lot, but i dont know which one of the country specific is the newest and right one for me. Can you help me out?
Looks like there's only one available in Intratech's official carrier firmware thread for O2 Germany (XWKI1), Checkfus says KI8 is available for O2 Germany (Dated: 22/11/11) assuming you have a I9100 (check the sticker under your battery to make doubly sure.
I don't know which one is more recent as Intra's firmwares don't have dates on them, but I'm guessing the KI8 available thru Checkfus is more recent as this would also be available via Kies. I don't think it will make a great deal of difference which one you use at the end of the day given you don't seem to know which firmware you had on your phone originally. Either will work just fine with your phone I would imagine, provided you definitely have a I9100 or I9100T
Up to you which one you use.

S2 I9100XXLP6 downgrading problems

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
http://forum.xda-developers.com/showthread.php?t=1075278
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] Unbrand 3 (Three) Italy Galaxy 2

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.

Flash back your original firmware or same stock firmware via Odin .

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

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

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
