                     <ol>
                         <li>Connect the device to your computer via USB.</li>
-                        <li>Put it in bootloader mode:
+                        <li>Put it in bootloader mode (USB device ID 303a:1001):
                             <ul>
                                 <li>if it already has MicroPythonOS installed, go to Settings - Restart to Bootloader</li>
-                                <li>if it's fresh from the factory, it's probably already good</li>
-                                <li>if not, try pressing the IO0 (BOOT) button while plugging in the USB cable</li>
-                                <li>if not, press the IO0 (BOOT) button while briefly pressing the reset button</li>
+                                <li>if it's fresh from the factory, it's probably already starting with USB device ID 303a:4001</li>
+                                <li>to force bootloader mode, keep the IO0 (BOOT) button pressed while plugging in the USB cable</li>
+                                <li>or keep the IO0 (BOOT) button pressed while briefly pressing the reset button</li>
                          </ul>
                          It should show up as "303a:1001 Espressif USB JTAG/serial debug unit Systems Espressif Device" instead of a regular MicroPython REPL serial device like "303a:4001 Espressif Systems Espressif Device".</li>
                         <li>After connecting it to your computer via USB, start up a webbrowser with WebSerial support like Chrome, Brave or Edge. If the browser was already running, you probably need to restart it.</li>
