Are you placing GPIO0 to GND while doing a reset or power up ?
Also, GPIO2 and CH_PD need to be pulled-up, while GPIO15 need to be pulled-down.

Im using this diagram
Is this the problem because it show GPIO0 as high and not low?

This is the correct configuration for running firmware, but not for flashing, you need to pull GPIO0 down then. Don't short but use a resistor (always).
