Burnt FS R6B reciever

Hey guys!
Just built a quadcopter with FS CT6B and FS-R6B… today I fried up my receiver by connecting to reverse polarity to power up… Opened it up and found out that LDo is just fine but the capacitor next to pins is destroyed…
Can anyone please walk me through to repair it? I need the capacitor’s exact info and what could I do to bypass it or repair it without working on these SAMD electronincs.
Thank You
