Unbricking a Kobo


This page is a work-in-progress.

The unthinkable has happened -- you installed a modification and it broke your device to the point where a manual factory reset was unable to fix the issue. Luckily, if your device has removable memory, your device can be saved as long as the issue is purely software-related.

Warranty warning

Opening your device voids your warranty. If your device is still under warranty, filing a warranty claim may be worthwhile.

Kobos with soldered memory or missing images

If your Kobo device has soldered memory or is missing an SD image, there is nothing you can do but attempt to file a warranty claim. The following devices have non-replaceable memory:

  • Kobo Aura ONE (N709)
  • Kobo Aura H2O Edition 2 (N867)
  • Kobo Libra H2O (N873)
  • Kobo Forma (N782)

SD card images are currently unavailable for the following devices:

  • Kobo Nia (N306)
  • Kobo Libra 2 (N418)

I'm not sure about the Kobo Elipsa (N604) or Kobo Sage (N777).
