Calibre / newer-device branch
Calibre covers on Kindle ColorSoft and newer devices
Older USB reconnect instructions do not describe every newer device. Use the current calibre source branch, preserve the original file, and treat personal-document workarounds as a feature trade-off rather than a guaranteed repair.
Record the symptom before changing anything
Start with the missing location. You may leave other answers “Not sure”: the result asks only for the next fact that changes your branch. A next-check plan is not proof of a repaired cover.
Selections stay in this browser and are not stored or sent. Optional analytics sends event names only after consent; unresolved results are not completions. The worksheet never asks for an account, book file, DRM state, title, author, serial number, or email address.
Optional usage measurement
The worksheet works without analytics. If you allow it, Yandex Metrica receives a page view and event names for a start, a source-bounded next check, or an unresolved result — never your selections. The provider can receive technical data such as IP address, browser details and cookies. No session replay or click maps.
Off until you choose. Changing this choice does not affect the worksheet.
