Also check free space - older Kindles need a healthy buffer for temp files and indexing and being near‑full will silently stall downloads. Use Storage Management/Quick Archive to purge big PDFs or Audible items, then toggle Airplane Mode, tap Sync, and leave it plugged in so the indexer can finish. If any entries from that series look stuck, long‑press to cancel them, reboot, and then try the USB Download & Transfer approach mentioned.

If you use tube bands with clips and handles check the ends more than anything else. The hidden failures start right where the tube meets the carabiner or the handle insert. If the sheath is frayed or the tube at the end looks thinned or chalky retire it. Replace worn handles or anchors because a sharp plastic edge can cut the latex. I also avoid tying knots in tubes to shorten them since knots create pinch points that chew through the material.
