IF your software successfully complete then simply change the LCD and then tell me...
or use other LCD Pannel

press home & power bottom bot in 15second to exit from dfu mode or you can use tinyumbrella to exit recovery mode

if there is no progress bar coming while restoring but software is loading ok according to itunes then its the components near the lcd jack that r water logged or broken or may be its the no lcd light issue thats it.
