I thought it might be my batteries too based what I have seen with previous posts about it. I put mine on a charger overnight before trying again (I have two new batteries on order due to arrive this week). Support just got back to me and said that I have to return to stock with my Edge CTS3 monitor if I flashed it with the Edge. I explained that the CTS3 is a monitor only and there is no other flash besides what I have done with HP Tuners.
I am theorizing here, but I asked support if the VCM Editor will write if it does not detect a tune on the PCM. The erase completed before the write failed. If that is the case, then it won't write my tune since it has been previously erased. They need to fix that if it is the case.
