Cannot Reinstall macOS from recovery

Find another local Mac, fetch High Sierra there, then use that to build a bootable installer, and transfer that bootable installer back to the problem Mac and boot that and erase and reformat as GPT HFS+, amd then install High Sierra. This is basically the sell-or-giving-away sequence, but working around the Recovery failure; whatever happened here.

If you want to start from the Snow Leopard DVD, that’s a different approach... But that’s also possible.

The Internet recovery approach can be very slow. It’s a ~4 or ~5 GB download, and that’ll take a while on a slower link or if the Apple servers get slow...

You must use the install DVD that came with that MacBook Pro

Same issue. I started the factory resetting and It's been more than 14hrs and still says installing the software. Don't know what to do??
