You can reset with myxperia following this guide (only if you have all those mentioned).

If not,there is no way to reset it without losing internal memory.
Sorry to say there is not - You would need to perform a system repair - Data stored on an SD card will be safe
If @alexdon 's awesome suggestion doesn't work then follow @Thommo 's suggestion
