psd file got corrupt, need help.

Sadly, if it's corrupted, there are no solutions, go back to a copy of the original image and start again and save regularly and always make backup copies.

You can try the various recovery tools available online, but don't expect miracles.

This is why we all have backups, and save incrementally during work on big files. If a file is corrupted, it's gone, so we need to take precautions.
