RFD 900+ fried due to overvoltage (12V)

Hi all,

Hope y’all are doing fine. After years using this radio, I finally screwed up and fed it 12V instead of 5V.
I see signs of “electrical burn” right above the pin #4 and a fried microcontroler (left bottom one).
I can’t seem to find the schematics to identify what seems to be burnt and replace it, can someone point me to where I can see it?
Moreover, has this ever happened to any of you and, if so, how did you manage to fix it?

Any other tips are more than welcome!

Cheers
