    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 Along without display using the other iphone Along 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 Along without display turning off..


    then restart again the phone Along 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
