Started by soldering a 4 pin plug onto the radio pcb
Desoldered the Sb1 - Sb2 points
Hooked up the stm8s to pc, Installed stvp from overkill rc's link (running windows 7 btw)
I was getting stvp stopped working crashes, So i then found the link to the patch for stvp. after i got that installed, i no longer got crashes trying to read the radio, but now i was getting cannot read swim error. I also tried doing what losi kid had suggested procedure after i snapped the stm8s in half. here

I have tried this on 2 systems, Windows 7 and on another computer running windows XP. I've tried normal stm8s board, snapped board, 2 different female molex cables. different usb ports, powered by thd stm8s, powered by the batteries. I checked my solder joints to the pin header and all are nice, neat and clean. Using a 3 pin cable, using a 4 pin cable, flipping the cables every which way. I'm at a lose here and have been messing with this for the last 4 hours trying to get it to work, any help would be appreciated
