How do I flash a custom recovery/ROM to my Galaxy Core Prime (SM-G360V)?

I've been trying to flash a custom recovery and ROM to an old Galaxy Core Prime. Based on advice I received on Reddit, I decided to try using Heimdall. I put the phone into Odin Mode and connected it to the computer. I then attempted to create a PIT file for my device, in order to flash the TWRP .TAR file to it. The process started, before I received the following error message: > Downloading device's PIT file... > > ERROR: Failed to send request to end PIT file transfer! > > ERROR: Failed to download PIT file! > > Ending session... > > ERROR: Failed to send end session packet! > > Releasing device interface... I don't know what happened. What went wrong? How do I fix this issue? If needed, here are some clearer photos showing my situation:
