Search for Check Fus and download it, download your firmware with it and flash it via Odin. ;-)

When you download your firmware you get a rar file, inside is a .md5.tar
Just extract it and place it in the PDA section of Odin and flash.

[Q] [QUASTION] unrooting my device.

I was looking for a thread about unrooting my galaxy s2 but i didn't find any tutorial with links and explanations about what is flashing and original stock and some other words that i didn't understand.

Thank you i think that this will do!
just flash a stock rom over the one you are using...
I assume that flashing is useing the odin but where do i get a stock rom?
Have a look at the xda bookmarks in my sig. There's both branded and unbranded stock firmware in there.
Ok so i download the israeli firmware for instance snd then flash it with the odin? Will it get rid of the triangle?

i9100..>Help Needed....

This should have been posted in Q/A however
you could try downloading Mobile Odin Pro from Google Play. Then go to Samfirmware.com and download your original firmware that came with the phone,( NOT A CUSTOM ROM). Unzip the file till you get to the .tar Put the firmware on the root directory of your sd card. Run Mobile Odin and install the firmware.
Mobile Odin
Buy Mobile Odin from play store (it's worth it and support @Chainfire) (here https://play.google.com/store/apps/details?id=eu.chainfire.mobileodin.pro&hl=en) and flash to XXLPQ to restore to stock.
Instructions=http://forum.xda-developers.com/showthread.php?t=1347899
Do not Flash XXLPQ if you have a variant other than the i9100 like SGH-T959
A thanks would be nice
Thanks guys

Yes. Don't change the name of the filename; *.tar.md5 is what it should be.

SII I9100 rooted OTA update

Hey Galaxy SII people, I need some help with a friend's SII.
I'm quite knowledgeable with custom ROMs and recoveries, but I have no idea what to do with a stock phone.
The phone is rooted and not getting the OTA to ICS. I want to get the OTA, losing root not necessarily a problem.
Can someone give me a hand with this? I have no idea what I need to do.
The phone also has the stock recovery.
I apologize if this has been asked before, but I couldn't find a conclusive, comprehensive answer.
Go to samfirmware and download the update firmware and install it via odin.
All the best.

Flash stock ROM from http://samfirmware.com/ via Odin. Search for galaxy S2 ROMs, just make sure you don't download the dangerous ROMs (the ones with a warning triangle next to them).

Thanks for the quick reply.
I'm downloading a zip now. I flash this with Odin/Heimdall? I thought I needed a .tar and a bunch of other files to flash with Odin.
This won't keep root, right? Is there any way I could get root back after flashing?
Also, will this wipe /data?
Oh, and I have the option to download a ROM for a specific carrier. Does that mean I can't use another carrier?
Edit: While I'm at it, is the stock recovery needed for anything stock ROM related?
Yes download will be in the form of a zip file, once downloading is complete you can extract the tar. file and place in the PDA section of odin. This will not wipe your device, well never has done for me. Yes you will loose root as you have a completely new rom with stock kernel. See the guide for rooting your chosen firmware. As for the carrier i always use the unbranded /open version as this has less bloat ware. All the best.

Make sure you don't have repartition button ticked or play with the pit file if you don't 100% know what you're doing either

Need some help plz!

Hey guys i have an issue. First off i have an unrooted GS3 on T-Mobile. I downloaded this http://www.sammobile.com/2012/08/25...-1-1-jelly-bean-test-ota-update/#comment-6605 which is a 4.1.1 pre release or whatever. Its cool but some apps dont work properly and force close a lot so my question is how can i go back to ICS or am i stuck with this now?(i know i can root but im really not looking to do that as of now) Also if im stuck with this will i receive the OTA from T-Mobile when they release the official update? I would appreciate some feedback please!!
1. Wrong forum.
2. Flash stock ICS firmware through Odin.
3. No you won't get an OTA from that firmware

You will need to find a stock firmware for T-Mobile on samfirmware.com or wherever (probably in the T-Mobile forum too)
Put the file in the PDA section in Odin and put your phone in download mode and connect it to the PC and hit start.
Yes you will get the OTA if you are not rooted and don't have a custom recovery.
N.B. make sure it is the correct firmware for your version, the US version, if you flash international firmware you will brick your phone. Search for firmware for "t999" there are two firmwares available there. I just checked but I can't link the page.
