Unroot/Restore to stock - Galaxy S II Q&A, Help & Troubleshooting

Hey I recently rooted my galaxy s2 using the zergling program, then flashed Resurrection ICS Remix v1.0.
Just for future reference if I ever want to restore everything to stock/unroot I just need to factory reset, flash stock kernal (XWKI4) and flash stock firmware (XWKI4) using Odin? If not what exactly do I need to do to restore it?
I couldn't really find a definitive yes or no answer so I'd figured I'd make a thread .
Thanks for any help =).

Yeah just flash back to a stock firmware. Use a USB jig to reset flash counter.

If after using the jig your flash counter isn't restored, you sould flash via odin an older bootloader then use the jig again and finally flash the new bootloader.
search at this thread for "bootloader".

Thanks for the info guys

[Q] Unroot Phone from Backup

Greetings All,
I rooted my phone a few months ago with the help of GalaxyS2Root on YouTube. As soon as I rooted it, I made a backup. I flashed the SuperNexus ROM and now the Resurrection Remix ROM.
I have attempted to restore the original backup I made prior to flashing the phone to the above ROMs and it succeeded (after altering the md5 file). I noticed that there's still the yellow triangle at the boot sequence which states that the phone is still rooted. How do I unroot a backup? Do I have to download an official ICS ROM or can I simply flash a file through Odin?
Some Details:
- Purchased Samsung Galaxy S2 in the Philippines UNLOCKED (i9100)
I apologize for the newbie questions.
Awaiting for your replies
Are you going to unroot? Well, you can unroot a backup. If you are going to unroot, use triangle away then flash an offical rom.

What do you mean by FLASH an official ROM? Through Odin? Are you talking about the ICS Official ROMS floating around? Wouldn't that wipe all my data?

Why return it to stock? I would recommend flashing an i9305 recovery from Odin then flashing an i9305 pre-rooted ROM via recovery....
However, heres how to return it to stock.

You need it to boot (With rooted) to be able to reset the counter though. It may not even need resetting yet though. Check download mode for info

Hey man, he is using the 19305 model from Australia.
I just need a link that refers me a site or post that will let me download the Stock rom, or any rom that will allow the s3 to be usable again.

Can i get a conform instruction on how to do this?i prefer not to do this with odin..because i already have a custom recovery...my recovery is CWM 5.0.3...do i need to upgrape my recovery first?
So you want to flash it via CWM, that's a completely different question.
You can also search for that.
Don't wanna flash with odin?
Mobile Odin might be the best tool for you.

1. Stock rooted deoxed rom 4.1.2 <<< -- to install this i need CWM for JB
2. Root on stock recovery <<<< -- to install this i need stock rom and stock recovery
3.CWM on stock recovery <<< --- to install this also need stock recovery

From all thing above..i need to know how to do this with ICS CWM that i already have....IF there is anyway pls let me know...

Check out Mobile Odin.

Well if you want to flash a official stock rom then you can only find them on sammobile.com and only way to flash it from odin. After that you can use Philz to install CWM if you want.
Hope it helps
