Enabling Developer mode and USB debug

I have an old Nexus 7 2013 tablet. It had virtually stopped working, so I did a factory reset. When I boot up it now goes into the Google startup screen and then to setting up a new account. It connects to WiFi but then at the next stage says Google play services has failed. I can't get past this stage. So I thought I would install Lineage OS. **How can I enable Developer mode and USB debugging without a working Android system?** When I connect with a USB cable to a PC, the PC doesn't recognize it. It charges but it doesn't show up on the PC as being attached. When I run adb devices on the PC it runs but shows no devices attached. I've checked the cable using another device and that shows up on my PC. **Is there a way to get my original Android system working or turn on Developers mode and USB debug so I can install LineageOS or some other OS?**
