After all, all devices have their dangers. The discovery of speech introduced communication – and lies.
- Isaac Asimov

Troubleshooting

Kindle store encountered an unexpected error

Faced this error and found a solution DiabloSat & Rexathion1

If an “Unexpected error” occurs when you try to log in to the Kindle Store or only the Kindle Store home page is displayed, try the following solution:

  1. Factory Reset Kindle
  2. Before registering your Kindle/logging into your account - plug your Kindle into your PC, move the WinterBreak files to the root of your storage space
  3. Log in account and enter airplane mode as soon as possible
  4. Connect Kindle to PC and delete the cache directory at the path .active_content_sandbox/store/resource/LocalStorage (Skip this step if the LocalStorage directory does not exist)
  5. Reboot Kindle
  6. Open the Kindle Store on your Kindle
  7. When prompted, click yes to turn off airplane mode
