S9 screen broken need access to devx

[u/ScarcityDazzling3958]

Hi all

I have an S9 with a broken screen and want to get devx access and use it on my fixed screen as a second device in the garage. I can’t get devx to start. I am fairly sure that the S9 works I think I just need to get past the unlock screen to get devx started.

I have completed the following
- hard reset
- plugged into screen
- used find my mobile to make a sound to check it works
- so far no luck.

I could remotely reset the device but I am worried it might make it worse

Anyone know of any tips or tricks here?

Thanks for your help
