This will reset the flash counter on any GT2. You would only need to do this for warranty reasons and/or returning to store.
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 do 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 volumedown+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). !!! 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 !!! ( and by brick I mean brick - only a board replacement or a JTAG unit will be able to save you, don't mess with boot(loader) stuff unless you *really* mean it! )
