iphone 4 NO Display.No light on Screen !
 

There is no dispaly at all on the screen.Not even a light ! But can received call and is detected by PC. Already check by placing a new SCREEN but still Not working !

this is the big prob in i phone
ihave also 3gs 2 pcs in my hand

it's a hardware problem you have to change display IC and you will fix it 100% , test by me

i had the same problem when i flashed it with a sn0wbreeze custom 4.1 for iphone 4g.


then i tried the 4.2.1 preserving baseband and is working 100000%

as observed this is the one of the problem in iphones

specially when it has a SEC CODE or LOCK CODE

try this...

get onother working iphone

then press the code of the iphone without display using the other iphone with display as basis..

then try to restart the phone by pressing home botton and power switch in 4 sec then press the turn off you will hear the phone without display turning off..

then restart again the phone without display by pressing again home botton and power botton 4 sec

patience because it will work 100%...



another option is...


restore your iphone to the same ipsw loaded at the phone

it also work 100%

dont use lock code again

try the method i posted its working.. done in 3g/3gs/ and 4g

theres no harm in trying

and

also

no

payment for trying :D
