Please see our user manual section regarding firmware updates by following this link: User manual: Updating the Trezor device firmware

If the above manual didn’t help:
Windows users: is there an error message saying that the USB cannot be recognized properly or that there is a problem with USB drivers? If so, there is a problem with Windows USB drivers failing to recognize Trezor in bootloader mode. Please refer to this manual to fix this issue: Device not recognized in bootloader_mode. -
If the above is not relevant or it didn’t help, check if the device is recognized by the device manager. If it is not recognized, try (re)installing the newest Trezor Bridge version from this source (once installed, please proceed by clearing your browser’s cache). After successful installation, you should see “trezord” process running in your activity/system/task monitor.

Trezor bridge is running and the device is still not recognized by Trezor Suit or Trezor Wallet? Try using a different USB cable or USB port, and make sure that you are connecting your Trezor with the cable directly to the host machine. Please don’t use a USB hub or adapter. Also, if possible, try connecting your Trezor to another computer.

Hi, I’m trying to get into an older trezor running 1.8.0. I downloaded the trezor suite for desktop on a computer that has never had the software before and when connecting the wallet it’s asking me to update the firmware. To do so, it instructs me to reconnect in bootloader mode. I do that, and the wallet is on and showing me it’s in bootloader mode, but the desktop suite is not doing anything. It shows the first check box is green, that’s for disconnecting, but it’s not seeing that the wallet is reconnected in bootloader mode. There are no other clickable options. What should I do next?
