Erase everything on the reader first: settings, reading positions, statistics and the saved Wi-Fi. Books on the SD card stay either way.

Your settings and reading positions stay unless you tick "Erase everything".
No port in the list? Unplug and replug the cable and try again. On Linux, see below first.
Pick the right board: the page checks the chip, and updates over Wi-Fi refuse another board's file.
Only the LilyGo T5-2.13 has been tested on hardware so far; the other boards are untested. See the project page and its docs.

Linux

Use Chrome or Chromium. Firefox has no Web Serial, so it can't install.
Chromium from the Snap Store (Ubuntu's default): it can't open the USB port until you allow it once. Run this in a terminal, then close and reopen Chromium:
```
sudo snap connect chromium:raw-usb
```
Or use Google Chrome from google.com/chrome (the .deb), which doesn't need this.
The port is listed but won't open ("Failed to open serial port"): your account needs access to USB serial ports. Run this, then log out and back in:
```
sudo usermod -aG dialout $USER
```
