Up to this date, every samsung Galaxy phone includes a “secret” hard reset Samsung mechanism inside them. This Samsung Hard Reset method includes the need for the user to input a secret code in the Android dial pad, as if it were a phone number to be dialed.
Actually this is a rather common way to introduce “secret” commands into your phone. In fact, Samsung has routinely implemented a plethora of “hidden” codes to perform different -rather technical- tasks, not only on their Galaxy line of phones, but on all of their phones.
Anyway, the specific code that performs a Samsung Hard Reset is *2767*3855#
The *2767*3855# code will Hard Reset your Samsung phone by performing the following internal steps: First it will reformat your firmware and then it will delete all your personal information and settings from it’s internal memory.
There is a second “secret code” which is a bit less drastic -but rather definite nonetheless- which is *#*#7780#*#*
This second code will limit the extent of the Hard Reset Samsung routine up to the deletion of all your data and apps only, efectively performing a Factory Default wipe out. As we understand it, this hard reset Samsung routine won’t fiddle with your phone’s firmware.
