In cryptocurrencies, a Wallet Backup (formerly recovery seed) is a list of words in a specific order which store all the information needed to recover a wallet.
Your Trezor device may accidentally lose power during the backup procedure. This might be caused by a poor cable connection or other mishaps. As the Wallet Backup is displayed only once, there is no way to read it again if the device is disconnected during the backup procedure. You have to erase your device and start over with the setup process. Although the process takes several minutes, it is strongly recommended to complete it as a very first step before you start to use your Trezor. Otherwise, you will not be able to restore access to your wallet in case of loss or damage.
Please follow the instructions below depending on your situation.
This case also applies to you if you have not used other Trezor services yet, such as GPG, SSH or Trezor Password Manager.

The dry-run recovery is a useful way to test your Wallet Backup. It is recommended to test your Wallet Backup before you wipe or factory reset the Trezor device. It is also useful to test it before every firmware update. It allows you to double check that your Wallet Backup is correct, which may come handy if something goes wrong during a firmware update and your Trezor is wiped.
You can recover your wallet with all its accounts, addresses and private keys using your Wallet Backup. This feature is used after your wallet is wiped from your Trezor or you lose/damage your Trezor and need to recover your wallet using another device.
In case you perform a recovery process or dry-run recovery and the result is "Recovery failed", "Invalid Wallet Backup", "Invalid Recovery Share", "The entered recovery shares are valid but do not match what is currenly in the device" or "The entered wallet backup is valid but does not match the one in the device", there are two possible options:
If using the Trezor Model T, Safe 3, or Safe 5, the words must be entered in order, directly on the device.

Your Wallet Backup is the essential 'record' of your Trezor device. Without the Wallet Backup, you will not be able to recover your wallet if your Trezor device is ever wiped, lost, or damaged.
Please follow the instructions below depending on your situation.
You need to move your funds to another wallet with the knownWallet Backup as soon as possible. More information on how to proceed in this situation can be found here.
If your Wallet Backup is lost and you are unable to access your wallet with your Trezor device, unfortunately there is nothing we can do to help you access your wallet.
We have no control over your Wallet Backup, thus the loss of a Wallet Backup is terminal, unfortunately.
