+Expand the **Update TFT display - Model** control and find the model that better fits your panel:
+
+![image](pics/ha_device_configuration_tft_upload_model.png)
+
+The options are:
+- **Use `nextion_update_url`:** This will indicate ESPHome to download the TFT file from the URL
+you specified in your panel's yaml setting under the ESPHome dashboard and is typically used
+when your device have issues to transfer a TFT file directly from the GitHub repository or when
+you want to use a custom TFT file hosted in your local server.
+This is the default option and this keeps the compatibility with legacy installations when this was the only option.
+- **NSPanel Blank:** This is a very small TFT file which just shows a pre-formatted QR code on
+the screen with a link to the instructions. Although it's not a functional TFT for controlling your panel,
+it can be usefull when you have issues in your first TFT upload, as it will remove the
+*Nextion Active Reparse Mode* used when a Sonoff's TFT and also
+when some other custom implementations are installed.
+- **NSPanel EU:** This should be used when you are using a Sonoff NSPanel EU model.
+- **NSPanel US:** This should be used when you are using a Sonoff NSPanel US model installed on
+it's normal (portrait) position with the buttons bellow the screen.
+- **NSPanel US Landscape:** This should be used when you are using a Sonoff NSPanel US model
+installed on the landscape position with the buttons at the right side of the screen.
+- **NSPanel EU (CJK languages):** This should be used when you are using a Sonoff NSPanel EU model
+and want to use the CJK (Chinese/Japanese/Korean) languages.
+- **NSPanel US (CJK languages):** This should be used when you are using a Sonoff NSPanel US model
+installed on it's normal (portrait) position with the buttons bellow the screen,
+and want to use the CJK (Chinese/Japanese/Korean) languages.
+- **NSPanel US Landscape (CJK languages):** This should be used when you are using a Sonoff NSPanel US model

+Once the right model is selected, please press the button **Update TFT display**.
+
+In a few seconds your display should start transferring the file correspondent to the selected model.
+The transfer screen shows a progress bar with a percentage counter with a black background.
+
+If the transfer don't starts in a few seconds, ESPHome will retry automatically a few times, with different transfer parameters, so the transfer can take up to a minute to start.
+
+Once started, the transfer shouldn't take more than 10 to 20 minutes. If after this time it isn't close to finnish, please cancel the process by restarting your device, then try it again.
