you can do that using LGNPST and use the right firmware (stock ICS or JB) , and then u should 100% stock .
just search in OG forum and you will find a complete tutorial .

if you still unable to do it , refer to this page

navigate down until you reach the stock AT&T firmware and the LGNPST .

Too bad your first [Q] is in the wrong section.
Updates are included in the custom ROM, and you can always flash stock ROM back. Now get your ass to the Q&A section.

You don't need to be rooted to install Custom ROM's.
For rooting you could use this thread, easy process, I like it.

OTA updates don't work worldwide. In some countries they work.
To flash any Stock ROM, use this thread,

As long as you are on any Stock ROM you will be able to do update via Kies.

if you wan't to upgrade you don't need to unroot, just flash firmware trough odin (addicted to your country)
also to unroot just flash with oding (stock firmware) and wipe data/factory reset and done,
threads are everywhere in general just look around

Since this topic is started might aswell use it instead of making a new one...so my question is:
From what I've read, in order to install CM7.2 on a Galaxy S2, you also need to install a custom kernel...so if I did all that, and want revert back to my original ROM and kernel, I just flash a stock ROM from Sammobile? Or the Kernel will remain the custom one (if so, how do I change it back to the stock one)?

Nope your kernel won't be left until you flash a Rom which has no kernel, but all Samsung roms out there have kernels inside the flashable tar or zip, you ain't smart if you don't provide a kernel which is made specially for the Rom

Looking for stock rom ZSKI3

I'm looking to download stock rom XXKI3. I need to return my I900 to the store and want to restore the firmware I had when I bought the phone. I am currently using MIUI v4 and don't want any hassle from the staff.
I am living in China and have only had the phone for 2 days. I noticed that the screen has screen burn/ ghosting, It's not very obvious, but after loading a pure blue image I can make out some of the display, and it looks like either a Chinese/ Korean keypad. I would assume then that the phone I got has been used before me, either by someone, or on display, which I am obviously not happy about.
I don't want to give them any reason to not give me a replacement phone.
All the links online I can find are dead, if anyone has it or knows where I can get it, I would much appreciate the help.
I have the files for Odin. Let me upload them and I'll post you a link!

This one? http://www.sammobile.com/firmware/?page=8&view=447
Thanks for all the replies! Oh man do I feel dumb, I posted the wrong code, it's actually ZSKI3 I need.
XXKI3 doesn't have the Chinese language, which they will no doubt try to switch the phone to when I take it in.
I can't find ZSKI3 on sammobile or anywhere on google. The link on the firmwares page on this site is dead too.
Any ideas?
Found it!

many thanks! i need that rom too
i upgraded my phone to 4.0.3 accidentially (kies prompted me to upgrade when i connect my phone to the PC, and i clicked the button to confirm the action wrongly)
since then, my phone sucks, hangs and crashed with some apps, even after i reset to the factory setting (cleared all the data!!!!)
now, my phone is likely to hang up, while i installed apk files (but it is ok to install app directly from google play) (the apk files are ok in the previous ver of andriod and should be the same as the one if i download them from google play directly)
so i decided to revert back to 2.3.5..................and would not upgrade the firmware again..................
Trying to flash to stock HK firmware since encountering a boot loop
I wasn't sure if I was in the right thread so I originally posted on here:
[Q] How to flash the original ROM?(HK official ROM)
http://forum.xda-developers.com/showthread.php?p=31073452#post31073452
Hope everyone doesn't mind me posting some questions on this thread too.
I am trying to figure out which official stock firmware for Hong Kong I should use (ZSKF1, ZSKF4, ZSKG2, ZSKI3) since I can no longer access settings on my phone due to the boot loop error. I am basically guessing since I cannot remember the exact kernel version or any other info. I am trying my best to make more educated guesses. I know I got my phone from Hong Kong in Nov 2011.
First I am trying to follow the instructions on this thread for the boot loop error. It requires me to find the stock rom I want to flash to. So I am working on finding the correct stock rom.

I was getting lost in the list of them on here. But I narrowed it the the 4 I picked out with code ZS for China, Hong Kong.

http://forum.xda-developers.com/showthread.php?t=1075278
For booshman:
The file you gave on this thread, it is for ZSKI3 but how do I know if it is right for my case? Will it restore to GT-i9100 Android 2.3.5 Gingerbread for Hong Kong stock rom? I had no custom roms and was running from the stock all the way through and I still encountered the boot loop error.
I already tried going on samfirmware but they only had Android ver 4 for Hong Kong. I want to restore my phone to exactly what I had before which is Gingerbread and start anew from there.
If anyone can give me some insights, that will be greatly appreciated!
Thank you all!!
I figured it all out! I got out of boot loop! No need for response. Sorry for spamming everyone...
Just wanted to say:

[Q] Help with RSDLite

I've been searching all over, where can I find a thread, or even the download link for RSDLite and the stock image (Not sure what it's called, I'm no expert at this). I'm on the leaked Jelly Bean update, and want to go back to stock so I can get the official OTA update to my phone. I would really appreciate instructions on how to do it, or even just link me the thread! On an unrelated note, I need to send my phone back to Verizon for a separate issue it is having which is why I would like it back to stock!
Thank you so much in advance.
I got RSDLite from here
and stock roms from here
let me know if you need any more help
