Basic netinstall script "bricking" router

All, I am having a hell of a time with my first script. Its extremely basic and just setting the acs url
There is likely something i have missed that i clearly need, the entirety of the “script” is just:

/tr069-client set acs-url="https://acs.mydomain.com:7547"

I netinstall routeros-arm (6.47.3), and tr069-client (also 6.47.3) and check the configure script pointing to this.

After clicking install, it takes the normal minute or 2 to netinstall, and all seems to work, however when I switch to an appropriate port and try to log in, the router doesn’t respond on the 192.168.88.1 address. I have tried holding the reset button and releasing when the usr light flashes, however it still never responds.

If i netinstall without the script it works fine, Clearly I’m missing something.

Also I know there is more that needs to happen then just inserting the domain(like actually enabling it), but I am trying to get the most basic thing working before going further.

You need to understand that when you provide a configure script, that script has to do all of the configuration. It will be run instead of, not after the normal configuration script.
You need to add the further configuration you require to bring up the device and make it able to connect the acs. Like setting the IP or a DHCP client.

Like I said.. I missed something super obvious. Thank you!
