If you have upgraded your FlashScan V2 cable to use the new BBL firmware (V2.5.xx or later), please change your FlashScan V7 (or V7.5) Scan Tool Properties to connect to the new FlashScan HAPI cable type instead of the old FlashScan V2 USB cable type. And uncheck Scan all cable types.
Setting this option will cause the EFILive V7 Scan and Tune software to attempt to communicate with the FlashScan device using the new V2.5 communications protocol first, instead of the older V2.4 (and earlier) protocol.
See attached image.
