How to hard-reset samsung galaxy ace I am trying to reset the phone, and when I reach the Android menu, I have a yellow alert at the bottom: can't access to /system/csr/PTR/system

Any ideas what should I do?

Thanks :)
To hard reset samsung galaxy ace,


Turn off your phone
Press and hold volume up, home, power button at the same time.
The Recovery appears, use volume up/down to navigate, power to select
Navigate to wipe data/factory reset and select
Navigate to Yes - delete all user data and select


And now resetting... (Make a backup of your phone first)

Navigate to reboot system now and select to get out of recovery.
