Unable to Boot pass logo or Restore OS

I did a reset a few months ago on this laptop and it was working at the time but the owner (my mother) didn't use it afterward because they have another computer they are using. The battery drained and it sat dead for some time. Now I've tried booting and it is stuck in a boot loop.

I can use some of the startup keys but these are the results

Command+R - does nothing

Shift+Option+Cmd+R - Starts the internet recovery, allows you to join the network, and then proceeds to download the recovery then shows "support.apple.com/mac/startup -1008F"

Option - shows the MacOS drive and allows you to choose a network. I've tried using a macOS on a USB made from another mac PC to attempt a restore. Enters BootLoop if either drive is selected.

Option-Command-P-R - Not sure if it resets the ram nothing is shown and still boot loops

D/ option - d - Same as the recovery

Can this be saved or is it a dead cause?

Try creating a Linux bootable drive (https://ubuntu.com/tutorials/install-ubu...) and boot from it. If that boots, we at least have some signs of life and can maybe recover macOS. Another thing to look at this might be this Apple Support article (https://support.apple.com/en-us/HT201255 I think you've tried most of these combinations, but it wouldn't hurt to try a few more. One that might be interesting to try is "T" for target disc mode. I'm just thinking out loud (or typing) here, so there is no guarantee that this will work, but maybe you could flash an OS onto the computer via target disk mode. Maybe you could hook it up to another computer and try flashing something onto it with balenaEtcher. Again, no guarantee, but might be interesting to see what happens.

Well, I hope all this ranting of mine helps you out. Good luck!
