try a DFU helper while plugged in to the computer
and by black screen do you mean the device is on and displaying black, or it wont turn on and there is no screen activity?   

[windowshacker]

there is no screen activity its like its dead

[theguitar]

Strange, software would not usually do that... Have you tried leaving it plugged in to a working cable/PC/outlet for a while?

[windowshacker]

yeah its completely  dead i had no hardware problems with this phone until now when i pressed reboot

Try holding the home/power buttons down at the same time for up to a minute, while connected to power. 

[windowshacker]

i did that nothing

i did that nothing

That's really not good, which OS did you reboot in?

[windowshacker]

Android

Android

Oof, it has been ages since I messed with this.  Not getting any response at all, not even recognized by a PC is really really bad.   Are you certain the battery is good in it?   Leave it charging on a wall charger for a day, and then try holding the home/power buttons again.

[windowshacker]

Ok I will do that and yes I'm not getting any response from the device

[windowshacker]

ok I did that and still nothing

I'm pretty sure that Whited00r doesn't support OpeniBoot and BootLace

Also, try to hold down the Home OR the Power Button.
I think that'll boot up the menu and stuff. and then select iOS, and then reboot it when the Apple appears (into DFU or Recovery Mode)

[windowshacker]

Still nothing

Did you have any issues with the device before, such as certain buttons not always working when pressed?
