Triangle Away can remove the yellow triangle from your boot screen as well as reset the flash counter, for a select few Samsung devices running Ice Cream Sandwich (Gingerbread builds are NOT supported).
!!! DO NOT USE THIS APP ON ANY DEVICE NOT LISTED BELOW !!!
!!! THIS IS A DANGEROUS OPERATION AND COULD POTENTIALLY BRICK YOUR DEVICE. PROCEED AT YOUR OWN RISK. A USB JIG IS PREFERRED IF YOU HAVE 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! )
Please check the values the app displays are correct before resetting the counters. There really isn't much more to say about it.
Also, Samsung may well change behavior for this in the future, so with any major firmware updates you should check and doublecheck if this app still works before attempting a reset.
Note: using Triangle Away may unmount your SD card. Reboot or manually remount it from Android settings.
This app has been used successfully on:
- Samsung Galaxy S2 GT-I9100
- Samsung Galaxy S2 SGH-I777
- Samsung Galaxy Note GT-N7000 *LP1 only, not LP5 or LPY, update coming*
- Samsung Galaxy Note GT-I9220 *LP1 only, not LP5 or LPY, update coming*
Variants that are NOT based on Exynos processors but rather on Qualcomm or Nvidia processors are NOT expected to work. I honestly would NOT try (until further notice) - examples are the Skyrocket and AT&T Note.

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.
