it is stuck in DFU (black screen)
actually it had 4.x installed on it previously and someone used factory reset on it then it stuck on connect to itune screen and itune showing invalid sim error. So i figured i just install custom 3.1.2 rom and everything will be ok
so can i restore another one like 4.x something ??? will it do the job ?
and nothing saved (no shsh no backup .. got this device in the above mentioned state)
please thanks a lot for your help!
