Rooting, flashing custom ROMs/recoveries is all well and good but if for any reason you need to take your device into a service center, your manufacturer can deny you warranty based on these things. Getting things back to stock is one way to avoid this but in case of some Samsung devices, you’ll need to do another step before you can get it into the service center. Samsung has recently started using something called a flash counter that records the number of flashes (custom ROMs or any other zip files that you might have flashed) and can deny warranty on this basis too. Resetting this to 0 will solve this problem too, and if this what you were looking for, read to know how you can do this.
I. Before You Begin
1. Back up everything you feel is important.
2. Make sure you have your device charged to 75% or more before you begin.

4. Use the Volume Up and Down keys to highlight to apply update from sdcard and press the home button to select it.

6. Once you see the install from sdcard complete message, highlight and select reboot system now.
