The 6 pin connector visible from the back of the calculator is not JTAG, it's serial with some control pins (reset, erase, power). There is a JTAG connector inside the case but you need very special equipment to use it.

Repairing the flash is totally possible with the USB board alone. You just need to perform a full erase to the flash with a piece of wire to activate the SAM-BA boot code.
