what can it do?

[someone]

Oh okay, out of the blue my w810i started hanging up. Then when I tried to turn it off and back on it displays the white screen though sometimes it boots up to the menu for awhile.

So I did a master reset but it didnt work, when I checked my phone status, it displayed my unit as k700.

So Im not really sure if its the EROM or GDFS thats wrong with it.

Have you tried a simple firmware flash?
Try that first. If it doesn't work flash you EROM. But remember to backup your GDFS first!
