Many Samsung devices store a flash counter that keeps track of how many times you have flashed custom firmwares to your device. On some devices, a yellow triangle or other sort of visual warning is also displayed during boot if you are running a custom firmware. TriangleAway was built to disable the triangle (if a visual warning is present) and reset the custom ROM flash counter to 0. This app requires root !
You can find out the current status of your flash counter and firmware state (custom or official) by booting into download mode on most devices. The usual way of getting into download mode is by first turning off your device, then turning it on by pressing and holding VolDown+(Home)+Power. Alternatively, the adb reboot download command also often works.
When you run TriangleAway, if your device and firmware are supported, it will show you the detected state of the binary (custom or official) and flash counter value, and the option to Reset flash counter. Please confirm that the information shown is correct before resetting the values.
On a number of devices, TriangleAway can work, but your firmware may not be supported directly. In that case, the app will tell you it needs to reboot into a special boot mode, which will be happen if you select Reset flash counter. The device will reboot into a special mode which will allow you to review the current status and reset the binary and flash counter values (or abort and do nothing). On some devices this will actually trigger the counter to 1 if its 0 - so if youre just checking, do that in download mode!
!!! THIS IS A DANGEROUS OPERATION AND COULD POTENTIALLY BRICK YOUR DEVICE. PROCEED AT YOUR OWN RISK. A USB JIG IS PREFERRED IF YOU HAVE A WORKING ONE !!!
Note#1: using Triangle Away may unmount your SD card. Reboot or manually remount it from Android settings.
Note#2: on new devices like the SGS3/SGNote2/SGNote10.1, status can only be reset on some firmwares - they must be stock firmwares!

Whether or not Triangle Away works depends largely on your kernel. Flashing a different kernel may make it work if it previously didnt.
Please also note that some devices set the counter to 1 at every boot if you are running a custom kernel or recovery. On these devices, Triangle Away may always display 1 - make sure to check the counter in actual download mode.

Note that this download is also available from that thread completely for free. You can go there and download it for free, or buy me a beer and download it from Market. It is 100% the exact same program.
Im not sure about future updates. For more details, read: http://www.chainfire.eu/articles/118/Triangle_Away_vs_Samsung/
