iPhone Hardware problems Changed everything

where he said hardware problem he just said modify host file of your computer :(

Changed the computer

The problem was screen Changed

would you please explain your problem clearly so we can understand there is a mix between hardware problem and software one
i will be pleased to help you

the 1601 itunes error fix is what i told you in my first reply
is your device on springboard or recovery or dfu ?

ok disconnect the screen recently changed
plug ur device and restore without screen if you have the same error 1601 check your HOST file note that itunes must be closed when deleting the 2 ip's
to take effect
if it persist try to restore to the latest firmware but take care with baseband
if you have unlockqble one use a custom one and pwned dfu it is safer

thanks a lot here's english hahahahaha

when i changed the iphone4's screen unfortunatly the new one was bad so
i have this problem ======> black screen how can i change the dfu mode and what is the IC responsible for dfu mode because it might be problem or may be the problem in the IC of the screen driver
when i pluged the device the itune gives me the error 1600 or 1601
i tryed the programs for this error and no effect
i also changed the screen so many times with defferent ones and the problem doesn't solved i changed the bord it self and still no effect
here's the problem clearly i neeeeeeeed solution
