Just got 2 from DX from yet another different batch. Message on DSTT Flash Checker 0.01 is: " unknown device : FF90C11F This is broken. (TT) " Work OK with 1.17 with the fake killer removed. Really difficult to open, bottom 2 lugs snapped off, inside looks OK, rounded slot etc. Another batch of fakes or just a different chip that Flashchecker doesn't recognise?
