Hi, as far as I know, you can only configure it vis LTWOO app. Perhaps you can try with another phone which runs the app.

Not sure if I got your question correctly, but if you are referring to the E-hook (of a Brompton), you can easily find replacement.
Or you may just find some steel wire and DIY.
