so little information

Please do this:
  • File > Preferences > Show verbose output during: > compilation (uncheck) > upload (check) > OK
  • Sketch > Upload
  • After the upload fails you'll see a button on the right side of the orange bar "Copy error messages". Click that button.
  • Paste the error messages in a reply here USING CODE TAGS (</> button on the toolbar).

Maybe you burned up the Arduino.
Maybe you are not following the upload sequence properly.
Maybe you have a bad cable.
Maybe you clobbered the bootloader.
Maybe you should try the loopback test.
Maybe you should try some troubleshooting.

No technical PMs.
The last thing you did is where you should start looking.

I change the crystal on board to 16MHz,

Change:
mega.menu.cpu.atmega2560.upload.protocol=wiring

To:
mega.menu.cpu.atmega2560.upload.protocol=stk500v2


After that Upload without issue

@vscelwan, please stop posting this all over the forum. Maybe in your very strange circumstance that was the solution but for you to post those instructions on a thread where the only information we have is "it used to upload, but now its not" is extremely unhelpful.
