Went to black box cal flash today and got $0503 error "script file not valid"--LS1B. After the failed attempt, I re-downloaded the latest beta softwares, wiped the config and SD card, re-saved the tune file in V7.5 software just in case. Reloaded the config and tune file to FlashScan V2.... did the "check firmware" button the V8 software and said all was OK. Had the same error when attempting to flash out in the car.
edit: Just tried pass-thru flashing. Works fine using V7.5 tune tool. Same error when I use V8 software.
I've been actively using it the past several months/weeks, worked fine on last beta. No other changes. Let me know if you need any other info or ideas to try.
