Boron powered in reverse

Hardware

Hi Community,

I powered one boron the wrong way (mix the + / -) and is no longer working. Is there a way to repair it or is it toast?

Thanks!

It is almost certainly permanently damaged.

If you are super handy it's probably the PMIC or voltage regulator, but they are very small SMD components mounted underneath the RF shield, so for all practical purposes there's no way to fix it.
