This is a 250GB Samsung 840
Stays Busy when powered on.
attempting to access safe mode to upload loader fails.
busy light fades and does not get RDR/DSC and returns with "Safe Mode : Error"
As you can see from the photos I am shorting the correct points.
Is there somthing im missing?

Hello. Sometimes pins for shorting might become covered with layer of oxide. My recommendation - use rubber for cleaning this contacts. Then - use tweezers for shorting. Should works.
