Triangle Away is another great product from XDA Developer, Chainfire. Personally, I don’t recommend using Triangle Away unless USB Jig is not working. Basically, Triangle Away can remove the yellow triangle from boot screen as well as reset the flash counter, for a select few Samsung devices that running Android 4.0 Ice Cream Sandwich like Samsung Galaxy S II (GT-I9100 & SGH-I777), Samsung Galaxy Note (GT-N7000 & GT-I9220) and Samsung Galaxy S III (GT-I9300 & GT-I9300T). The flash counter keeps track of how many custom firmwares you have flashed and this voids warranty. So Triangle Away helps to recover warranty back if you have flashed custom firmware or kernel.

Note – Only use Triangle Away for Samsung Galaxy S3 if you know what you are doing. And process at your own risk. Finally, do study more information at XDA website.

USB Jig is a hardware device, right?
Yes.
THANK YOU U R Very useful XD
Does triangle away work on 4.1.1 version for Galaxy S3?
Some users reported yes. Anyway, you can always revert back to Ice Cream Sandwich firmware which Triangle Away is working fine on.
Hi jayce,
Does the latest Triangle Away ver. 2.0 work on S3 either ICS/JB? It doesn’t seem to read the Current Status of Flash Counter. Can I still proceed to run Reset Counter Flash without this status?
Yes (but I didn’t try on JB).
Ok… thanks!
how to install the triangle away to s3?
Hi Carsley, please refer to this guide. Note – no point to use Triangle Away if you are not going to send it back for warranty claim.

thanks i watched this one but i was wondering if i can get every thing official but still keep roothttp://forum.xda-developers.com/showthread.php?t=1952282&highlight=guide+how+to+be+rooted+retain+custom+binary will this method work or am i dreaming
No idea, I did not try that. Just refer to those who tried it. But rooting still void warranty if Samsung in your country is strict. So that guide is useless to me.
