Field Test/Engineering Mode

Hi,

Anyone knows how to get to the Field Test/Engineering mode for the Prevail? I tried the codes for other Samsung phones, but didn't work.

Thanks,

Haris

What does it reset?

something with the gps but I am not sure

what i am interested in is the one that asks for the password which is not the MSL

##25327#

if you convert the numbers to letters it spells

##clear#

I wonder what it clears

A possible alternative is to go to your dialer and enter ##3282# and click Enable HFA. HFA=Hands Free Activation. I tried this and my phone rebooted and reactivated w. sprint. You may need your MSL. If you don't know how to get this number do a search..

I guess it is hands free activation
