Trying to use the medusa2 and each time i connect to the logic board it says No chip seen (L), even on a known good logic board. Once, i was able to get it to connect and read the efi info, but on the next attempt, it wouldn't read from the same board. Has anyone had this issue and what did you do to solve this? Also, do i need to apply power to the logic board to get the medusa to see the chip. Currently working on an 820-00165 board.
