It sounds like you are doing all the right things.
The Blue cloner is very tricky to use on an xSeries.
I have 3 suggestions:
- The write may have worked, but just not beeped, have you tested it?
- Try modding the Blue cloner, . I did mine out the side (I really should dig it out and take a photo ) rather than out the end like is shown in Roscos write up.
- Rather than $320 on the RDV4, You could buy an Easy for $30 -$60
I hope that helps
