Can I get a step-by-step guide on how to edit a poor quality photo - which is unreadable?

Czy mogę uzyskać przewodnik krok po kroku, jak edytować zdjęcie niskiej jakości - które jest nieczytelne?

How to improve the quality of the photo? At the moment I have a low quality photo and I have an unreadable email address in the photo.
Send me the name of the filters available for Adobe Photosop - I need to get an improvement in the quality and readability of the photo. Can you send me the name of the filter or several filters to fix the quality of the photo?

There isn't enough pixel data there to work with.  IMO, no amount of sharpening could save that image.
