Unable to switch from teathered to wifi install

### Prerequisites

- [x] I have read [CONTRIBUTING.md](https://github.com/EFForg/rayhunter/blob/main/CONTRIBUTING.md)

### Rayhunter Version

v0.9.0

### Device

Orbic RC400L

### Installer OS

macOS

### Describe the Issue

If a user installs using the orbic-usb install method. There does not appear to be a way to convert to the normal wifi install method.

The FAQ seems to indicate that it might be possible with `installer util`, however the provided instructions do not work for Orbic devices.

```
./installer util shell "echo 3 > /usrdata/mode.cfg"
error: unexpected argument 'echo 3 > /usrdata/mode.cfg' found
```

Device does not respond to the installer.
```
./installer orbic --admin-password 'password'
Logging in and starting telnet...
