I tried to enter it software again but it disconects durning sunchonizing with iTunes becouse ipone resets

While it was "lagging" it was actually performing background tasks, you aborted those tasks by resetting and screwed your phone. Restore.

Place the phone into DFU mode. Connect the iPhone to the computer, start up iTunes. Now hold the Sleep & Home buttons for precisely 10 seconds, release the Sleep button, keep your finger on the Home button until iTunes says its found an iPhone which needs to be restored.
