ok i was updating my v2 about two weeks ago. i did not really get anywhere with the process, however it asked me to upgrade my boot block. I never did as far as i know since i was not sure of what the boot block was. well fast forward to today and i was able to scan fine however i tried to read a tune out and i keep getting the error you see in the pic below and it wont complete the operation. What is this and should i upgrade my boot block and what exactly is it???
