Usb PORT, transfer THE battery, warranty
What kind of brick? Usb port is manually broken? If is, you lose warranty. Samsung reject free service if phone was damaged. To reinstall recovery on stock, you need working usb to flash original recovery by odin, only thats the way. To remove counter and status rom to official you need rooted phone and use Triangle away app in phone. Check in manual of triangle away, can you use triangle away with your phone. If not, you use it on your own risk - at least you can totally broke your phone and nothing help. Then you buy new one. But btw if your usb port is damaged you pay for repair, so problem with custom recovery go to 2nd plan.
