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. Note that some newer device like the S4 do not show you the flash counter anymore - but it is still there.
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 you're "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.
( 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! )
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 SGS4/SGS3/SGNote2/SGNote8/SGNote10.1 etc, the "system modified" status can only be reset on some firmwares - they must be stock firmwares!
- Triangle Away shows a negative counter ?
If you have a very large flash count (over 127) this is known to happen. Please confirm in download mode that you actually have that large a flash count before resetting the counter.
- After using Triangle Away I get no bootscreen at all or an error message on screen ?
Try flashing the attached "param.tar" as PDA in ODIN (no repartition!), that may clear up the issue. Samsung Galaxy S II GT-I9100 ONLY
- What about future updates and devices ?
Please read this article I wrote about this: http://www.chainfire.eu/articles/118...ay_vs_Samsung/
- On my SGS4/SGS3/Note2/etc, Download Mode says my System is modified, and Triangle Away does not reset it
Triangle Away attempt to reset this status and block it from coming back, but it depends on the firmware. It does work on some (not all) stock firmwares. Resetting this value often doesn't work on custom firmwares! See the post below this one for more information.
- On the SGS4/SGS3/Note2/etc, System->Settings->About device->Status still shows "Modified"
This is outside the scope of Triangle Away. The "system" status is not even always resettable in the bootloader. If you are going for warranty, you need to also reflash a full stock firmware and wipe your device. If they boot up your device and find root apps, you're not going to get any warranty anyway. If you do such a full stock reflash and wipe, the "Modified" value will go away. The workaround option in TriangleAway may help you temporarily change this value. See the post below this one for more information.
- My counter always stays at 1
Some devices/bootloaders 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, and make sure you are running a stock Samsung kernel and recovery.

Various Qualcomm-based Samsung devices should now be supported as well, but I don't know which ones - please let me know!
Suspected is a large range of Qualcomm based Note and S2 variants.
** Various related models are supported depending on firmware, but only the exact model numbers listed are supported regardless of firmware version.
Whether or not Triangle Away works depends largely on your kernel. Flashing a different kernel may make it work if it previously didn't.
Download from Google Play
The Google Play download is not free - it costs about a beer (thanks!). The download listed below is 100% the exact same program, but free. I provide it for free because I believe this app should be available even to people who cannot pay on Google Play. If you are able to purchase on Play, please consider that I have spent a great many hours on this, and the latest version also uses server resources I have to pay for.
