Troubleshooting Update Issues
Received an error message when selecting "Update Your Kindle".
Unsupported software modifications are present.
The Kindle doesn't support software modification, and will be unable to update the Kindle software if it has been modified. Contact the original developer of the software modification for instructions on how to remove the modification.
