Ok.
Nothing personal, but this is chasing symptoms, not problems, yeah?
Busybox is a low level app. It's a Swiss Army Knife. Installation includes a bunch of shortcuts for common unix commands, missing from a compact embedded os like Android, but provided through that Swiss Army Knife payload. Nothing more, nothing fancy, nothing mysterious.
Everything you saw after a bad Busybox wasn't a problem, it was a symptom, ok.
By the numbers - thankfully, you've proven that our s-off is truly permanent.
Hboot of 1.15 with s-off means you have s-off, but you have a scrambled bootloader.
Flash LazyPanda 1.12.2222 again.
Fastboot flash, or fastboot install, the latest TWRP. Leave CWM out of it.
Leave radios and an RUU out of it for now. That's all trying to get in the back door of proper partitions when the front door may still be open to you.
Once flashing LazyPanda 1.12.2222 and the current TWRP, go into TWRP settings and reset your paths.
Then try a nandroid restore.
Report back at that point.
Absolutely - Don't Panic.
