[Q] confused

Hi Peeps
So a few months back the wife managed to get a Samsung S2 from Orange
I Rooted it and unlocked it Thanks Chainfire
She then a look around xda and said she would like the lighting rom please. So Thats what I did. 1.5
Now 3 months later and Daughter has a s2 as well.
Wife now wants hers to latest stock.
Thing is I don't have a clue about all the firmware numbers. I just get confused by all the latest xxs and kes w and what ever plus 2.3.3. and 2.3.4 etc etc etc. would some nice person please point me at the latest unbranded stuff for Samsung S2 I have read the brilliant posts and threads by infatech but that just makes it worse lol.
Please help
Others may wish to take issue with this, but as far as I can tell, there is little difference between XXKG5, XXKG6 and XXKG7.
XXKG6 marginally pre-dated 5 & 7, and 5 seems to be better regarded than 7. 6 Seems to be a semi-official test version.
I guess the advice would probably be XXKG5, but I use 6 and am perfectly content with it.
Thanks Gustopher.
and I can get XXKG5 or XXKG6 or XXKG7 for UK from???
You can pretty much flash most Stock ROM with their modem (baseband). You just need to try which is best for you.
The webversion of Check Fus 2.0
There you can download CLI or Windows version of Fus Downloader. For Windows version, you need to have .NET framework 4 installed.
You can download most stock firmware using the Fus Downloader.

I9100XXKG5/I9100OXAKG5/I9100XXKG5/I9100XXKG5
Version:
Android 2.3.4
Model GT-I9100
Product code GT-I9100LKAXEO
HIDSWVER I9100XXKE2/I9100OXAKE2/I9100XXKE2/I9100XXKE2
Just unzip the file you download, then select the *.tar file under Phone in Odin, and flash.
t xxkg6 from this thread and just change the csc for uk which isa one the files under the xxkg6 section.

Forgot to mention, you can go to the Settings -> About Phone menu, and see what ROM+BASEBAND+KERNEL your daughter is using, then download that exact same rom. Which is probably better for you, since if one have problems, then they both have the exact same problems, and by association, THERE IS NO PROBLEMS... Just like Apple iPHONES.
I would go KG6 firmware and modem and drop back to KG3 if problems .

Why don't just wait for the official update?

Because he used a custom rom which means as you know kies will not work on the phone to get an official update and he wants to go back to stock or the latest stock he can get.

Is 2.3.3 really the latest software for bell gs2?

Been looking for an answer online and can't seem to find one, my girlfriend bought a used bell gs2 and when i plug it in kies it tells me it has the latest software yet it seems that 2.3.3 as been out for a long time and should have been updated by now no?
Thanks
Kris

If you check this thread here UGKG2 is the only firmware bell has put out, so if thats the one you have, then yes, thats the only firmware there is, blame bell for being slow.
If you want to flash a new upto date rom, follow this guide, it also has download links, KK5 is generally a good 2.3.6 firmware at the moment, dont go for the ICS roms, there buggy.
It also should be non wipe aka you shouldnt lose anything as its stock firmware to stock firmware, but no promises and you would be advised to backup stuff first.

[Q] From custom to stock firmware for OTAs

Hi, I have a Samsung Galaxy S2 on the three network. If I flash the H3G 2.3.3 firmware to the device using Odin will the OTAs still work? If not is there a way to flash the standard firmware back and have the updates working as normal?
Thanks
If you flash stock firmware for your region, you should be able to get updates OTA again. In saying that, I've seen more than a few cases where this hasn't been the case (Why ? No idea. Never happened to me/not important to me as I don't use stock firmware so I've never delved into the why).
So you can flash stock firmware, see if you can get OTA updates.
If not, might as well take the easy course & flash your stock firmware updates via Odin (like many people) rather than spend potentially who knows how much time trying to find out why OTA won't work in spite of you going back to stock
It works for kies and OTA
I downloaded the original 2.3.3 and flashed it to my Samsung Galaxy S2 and the OTA updates worked up to firmware 2.3.5 and then I plugged into kies and it updated to 4.0.3. I used this site http://www.sammobile.com/firmware/?page=3&t=1&o=1&m=GT-I9100&r=-1#modelsa
Thanks for the help guys.

help with bell 1717m

hi
purchased a bell i717 with official bell ics installed.
tried to get it unlocked but fastgsm and cellunlocker could not unlock via usb or iemi.
found a user in anothe i717 thread unlocking but had to revert back to 2.3.6
i now canot get kies to update to ics official.
what i am looking for is bell official ics for odin flashing.
or a good custom rom for the note.
any help would be appreciated .
i tried stockroms.net but they only have the 2.3.6 which i downgraded with.
i have gone thru dozens of threads but no good links to bell official ics for the i717
thanks,jeff
Samfirmware.com has the stock bell ICS ROM.

And its in the .tar format for Odin3. Get the password while you're downloading the rom.
thanks to both of you,thats exactly what i did .
haven't checked if kies will let me update but the samfirware one got me back to ics.
Kies will let you update with your stock phone. Just don't do anything besides unlock it. After you upgrade you can flash CWM and root.
OP....could you please put the word "solved " in your thread title ?
It helps other users to find solutions to their questions, and keeps the threads clean.
Thank you !!.....g

If you wanted rooted stock, via Odin, you can look here:

For some reason, I never remember seeing a regular Odin version of the non rooted software. Heimdall version works fine. Have used it before successfully.
