Things to note before upgrading

After updating the device do I need to enter the recovery seed again?
No, updating your device firmware will not wipe off your recover seed from the device. Also upgrading will not affect your cryptocurrencies in anyway. Once the device is updated you can enter the PIN and access your wallet as usual.
All your private keys will remain absolutely safe after the upgrade. But as a safety precaution you need to keep your 12, 18 or 24 word recovery seed handy.
It is very risky to update your device without having your recovery seed in place. We highly suggest you to refrain from updating the device if you do not have the recovery seed.
In that case send your coins to your exchange account, then perform an update. Then setup a new wallet, make sure to backup the newly generated seed word and then send coins back to your Trezor wallet.
If you have the recovery seed but not sure if it is the right one then perform a stimulated recovery to check your backup.
