ELI5:What is causing this specific version of the Galaxy Note 7 to have so much trouble?

and why couldn't they fix it after recalling the device and issuing new phones?

If we knew the answer to that question, the problem could be addressed. Given that Samsung has suspended manufacturing it seems likely that they don't know, or cannot fix it.

As for what is burning, the battery is a very high energy storage device. Getting energy out to power your phone needs to be a strictly controlled process. Burning happens when the process gets out of control.
