After reading that the 2.1.7 firmware required use of the SD card at all times now, I thought maybe my SD card was actually faulty. When I removed it and put it in a PC it wasn’t even detected in the PC. I formatted a new card and it has been reliable ever since. Perhaps give that a shot before you replace your unit.
