So the firmware upgrade to 5.6 isn’t good enough ?
If you still trust CoinKite you need to update the firmware and only then generate a new seed to move funds to.
Even better is to generate your own seed with enough dice rolls, add a strong passphrase and if you're comfortable with that, go multisig with high entropy seeds stored on devices by different manufacturers.
