''The next step I did is I remove the battery then insert my phone to my Laptop then I plugged back the battery, it wasn't detected.'' Do you mean you connected your phone without battery to laptop? And then while the phone was connected to laptop you inserted the battery? This would likely damage the main board due to surge in current. Hope you can resurrect it! good luck and let us know if it works.
