Need to return back to stock, PLEASE HELP!

[Andrey Nazarchuk]

So my dad gave me his GS3 (SGH-T999L) and I decided to get CM11, so I followed a tutorial and rooted my phone and got CWM recovery, then I went to the CM website and found CM11 for my phone and flashed it with CWM recovery. It was all working great until I went to the beach and *accidentally* dropped my phone about a foot onto the rocks and now my screen is cracked:'(. The phone is fully operational but I don't want to use it with a cracked screen. It still has a factory warranty but I am pretty sure its void because my phone is rooted and stuff. So my question is: How do I get it completely back to stock and unrooted, stock Rom and (OS counter?) back to 0 and official so I can claim repair?. Thank You!
More information:
I did a backup in CWM Recovery after rooting but before CM11, but that's not much help cause I need stock-Unrooted-untripped KNOX
If you need anymore information, then just ask
(P.S. feel free to grade my grammar, I am trying to improve it in response to the horrible grammar I have seen around the Internet lately)

To reset the counter, you'll need Triangle Away from Chainfire. You can download it from the play store or from here: [2014.01.15][ROOT] TriangleAway v3.26 - XDA Forum

Then you'll need to enter download mode and flash a stock firmware.

There is a written guide here: [Tut] Unroot the Galaxy S3 (for stock updates/warranty) - XDA Forum

If you need help, feel free to ask! It's better if you do before you attempt to do something.

Hey, sorry for bothering you, and I'm not trying to be unthankful or anything, but the second link seems to point to a tutorial for a Samsung galaxy s3, and my model is the T-Mobile s3 T999L. Sorry if the model number doesn't matter.

Yep, the process should be the same. Flash the firmware in Odin.

Here is more help: http://forums.androidcentral.com/am...ide-samsung-how-flash-stock-rom-via-odin.html

This is straight from one of our ambassadors here in the forums.

Definitely helps.

If the phone is running 4.3 it will have Knox. Since you are rooted and using CWM the Knox Warranty Bit will be tripped. There is no way to reset the Warranty Bit. This may be a problem to get Warranty repairs or replacement.

Yes, it was running 4.3 before it was rooted. So you're saying triangle away wont work?

It will reset the flash counter, but it can't do anything about Knox.

So which one is Knox? The one that's says warranty bit?

Yep. Once you trip it, your warranty is void.

Oh, so I guess I'll have to fix the screen myself

There are plenty of guides on how to do it.

Here is an example: https://www.ifixit.com/Guide/Samsung+Galaxy+S+III+Broken+Front+Glass+Replacement/14856

 

[Andrey Nazarchuk]

This will work for the LTE version also right?
Would this be good for the Samsung Galaxy S3 SGH-T999L T-Mobile?
