So, I've created OnDocFormRender plugin mentioned earlier by me and got success again. Now it works with images, files (located in assets/images and assets/files) and tinyMCE. Don't use it in production!
The second step is to add more MODx to integration - move KCFinder settings from config.php to manager, add check to prevent KCFinder running not in manager - it's very important because everyone can delete (or upload

)everything in assets/files or assets/images using direct link now.
To install:
1. Unpack kcfinder.zip to assets/components/
2. Replace tiny.js in assets/components/tinymce with one attached in zip. It's a hack, but I didn't understand the loading of tinyMCE.
3. Create plugin using kcfinder.txt and bind it on OnDocFormRender event.
4. Try to change settings in assets/components/kcfinder/config.php
