One of the annoyances with the Samsung Galaxy S2 and all its variants when flashing custom ROMs and kernels is the flash counter, which is incremented every time you unofficially flash a firmware or a kernel. Also, a big yellow triangle starts showing on the screen every time the phone is booting up. They say it’s for warranty purposes, so that Samsung can deny service to those who have modified their phones by unofficial means. In short, it’s a big nuisance.

However, if you own either the T-Mobile Galaxy S2 SGH-T989 or the Telus Galaxy S2 SGH-T989D and have flashed custom stuff on your phone, you can reset your flash counter thanks to a hack by XDA modder -Mr. X-. The hack will reset the flash counter without the need to use USB jigs or other complicated methods for resetting the counter.
