How do I fix a Kobo eReader that will not sync?
Answer
Sign out of the Kobo account on the eReader, restart it, sign back in, and sync again on strong Wi‑Fi. If desktop sync also fails, check Kobo account status and try syncing from the official Kobo desktop app after a sign-out there too.
Before you start: stop right away if…
- Signing out can require re-downloading books and may remove some local sideloaded items depending on setup.
Follow these steps
Sync on a known-good Wi‑Fi network
Connect the eReader to a stable Wi‑Fi network, ignore VPN if one is used on a hotspot, and tap Sync once.
You should see: Sync completes, or a clearer error appears.
Sign out, restart, and sign in
Sign out of the Kobo account on the eReader, restart the device, sign back in with the same account, then sync again.
You should see: Library and progress begin updating.
Repair desktop sync the same way
If the computer also will not sync, sign out of the official Kobo desktop app, restart the computer app, sign in, and sync with the eReader connected or over the account library.
You should see: Desktop and eReader show the same purchased library.
Check account and support paths
Confirm purchases appear when signed into Kobo’s official account site; if they do but devices still fail, contact Kobo support with the exact sync error text.
You should see: You verify the account library is intact and have a support path for device sync bugs.

Extra tips
What to look for: Sync error messages versus a silent hang, Wi‑Fi full bars, and whether both eReader and desktop fail
Before you change anything: Note which Kobo account email is signed in. Back up any sideloaded important files if possible. Use known-good Wi‑Fi. Avoid random third-party sync tools.
