Those pins on the BT module aren't actually connected to Espruino, so I'm not sure they'd cause huge problems.
Do you have a volt meter? Could you check the voltage between 3.3v and GND when the board is on?
What were you doing when you 'bricked' the board? Had you uploaded some particular code?
It is possible to erase the flash memory used by the bootloader, which would then stop the board from booting. You'd need a USB-TTL converter to re-flash it, but it's about $5 and then the process is relatively easy.
