Hi Jerome, this is very promising. Is it possible to extract this (I assume this is the curcfg xml?) from the router without having to open it up to expose pins? Have a B315s-938 I'd like to repurpose as a backup WAN for my fiber connection, and I recently got a DITO SIM which I'd like to get working. I did a bit of digging on this router a few years ago and managed to emulate the SCRAM authentication used by the Web UI to automate some stuff, but I haven't been able to figure out how to recover the administrator password through the REST API. Thanks
