Hi Jan. My name is***** you for your question and the opportunity to assist. If the phone still turns on there is still hope.
If you plug the phone into your PC via USB cable and Windows recognizes it, you may be able to access your pictures and copy them off the phone. Your contacts may be recoverable as well but I can't say for sure. Try to see if you can get your pictures first.
Thank you. What version of Windows is on the PC?
