Get a new SDCard and download a copy of plain Raspbian 2017-07-05. Write the image file to the SDCard with http://etcher.io

Boot your RPi from that new SDCard. Mount your other SDCard in a USB SDCard reader. Mount the SDCard reader in your RPi.

Use the new (untouched) system to repair the changes you've made to your original SDCard. Swap back, boot from the original then grab a beer to celebrate a job well done.
