I have a PCB3b dual-power Willem that I've been modifying to do 25V VPP. I replaced two transistors, the inductor, and the 7805.

VPP and VCC are now great in test mode, however when I try to program the software gives me "Hardware error: check power & connection".

How do I fix this?

I started a topic on the ezoflash forums, but it's sat unanswered for a while:

This is nothing to do the VPP.

It related to your data cable connection and power cnnection.

Use self test procedure to check it.
