After you downgrade from 3.50 to 3.41, you do the exact same method.
Put the same lvl1 diag file and for the 3.15 file, just use the regular one. It'll work as long as you are on the modded 3.41 in service mode. I had this problem too.

P.S. ~ This should be in the questions section

i thought you didnt have to downgrade to 3.41...i'm pretty sure you can do it straight from 3.50 to 3.15, just get the modified pup file
