Fried my teensy 3.6

I was troubleshooting my circuit and was trying to read the DAC output on A21/DAC0 which was going to the input of an op amp. My probe slipped and I shorted the -12 V powering the op amp and the input / A21 / DAC0... so I fried it and the teensy. It no longer registers as a USB device, and the 3.3 V pins read ~1 V.

Anyone have any clue if it can be salvaged by replacing any necessary components? Or do I mount it on the wall of shame?

Thanks.
 
Then it might be worth having a go - the processor is obviously gone, but its possible other things have followed.

With a BGA package I suggest finding some video tutorials - in theory you remove old package, clean the pads and
use a suitable amount of flux, carefully position the new one and wait for it to sink down as the solder balls fuse.

If it were me (never done BGA yet) I'd practice on a few small cheap BGA chips
