BEST REGARDS

This is strange. "Unlock" operation doesn't affect phone's boot loaders. Please try to fully charge phone's battery with external charger and put the phone into Download Mode again (reconnect the battery, press and hold "Volume-" + "Power ON" buttons).

what should i do now
and there is no tool can repair it

As I have said above, "Unlock" operation doesn't affect phone's boot loaders. Try to fully charge phone's battery with external charger and put the phone into Download Mode again (reconnect the battery, press and hold "Volume-" + "Power ON" buttons).
Anyway, we will research the problem and write You the result.
