i was playing with my phone then i found some hidden menu
all i did was remove the battery replaced it and held down on the volume key and right on the d-pad then i held power.
so that's all three keys at once.
then some screens ran it was like screen 1 then the colors then 2 then the colors then 3 then it staid on the colors and the only way out is a soft reset or removing the battery.
also if i plug it into my pc at the bottom of the tri colored page the world serial will change to usb then if it says usb and you remove the battery nothing happens.
check it out

i thought it was pretty cool try it out.
im guessing it checks for some type of recovery dongle
let me know what you think, is this old news?
