Where can i learn version when phone is dead.
 

where can i learn the version of GD series when the phone is completely death.

With CHKBOX you can.. but if CHKBOX won't
connect with phone - drop you phone to the
window 8-(

it mean that bootblock of flash is distroyed!

Not hurry!
My telephone too was dead but now it works.
It not connected with chbox or other repair prog, only connected by winmodo. I am reflash it by Winmodo and then repair other programs.

You're lucky 8-)
