Notes :

  • Triangle Away may unmount your SD card , you can mount it from storage settings
  • New devices like SGS3/SGNote2/SGNote10.1, status can only be reset on some FW - they must be official firmwares !
  • This process works for various Samsung galaxy devices like (S3/2,Note1/2/10.1",Tab)
  • It does work on some (not all) stock firmwares. 
  • Resetting counter value doesn't work on custom firmwares
  • 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
