Problem with update M50
 

Hi,
I have m50 with sw.090408 and I tried to upgrade to 170408 but it doesn't want to start.
I tried with and without pre-check but the result is the same: No Bootcore detected !
I use a no name cable(3 wires) and it's OK!
Any ideas ?

hi
try with pre-check and post-check

I tried already- the result is the same!
Is there anybody who knows the way for upgrade from sw.09 to sw.17 with winswup?
