The optiflasher no ca found fix goes over the usb service port.
See advanced button, detect ports, choose the correct comport, enable the no ca found fix, do job.
After that you can close this program.

But I think it's no longer needed, so go to the next step.

Sim 2.10 Sunray boxes.
Uploading bootloader and image file you can do with SunRay- FlashUp, for the normal instruction for Sunray boxes see this.

If you somehow can't get a connection with your browser, use then the SunRay- FlashUp flash button to upload the ssl84 bootloader and image file and if you still get the no ca found issue, upload the ssl84 bootloader again.

Normally this should be enough to get the box running, if there is no hardware issue with the box.

But maybe...
Also, some Sunray boxes have a jumper on the motherboard, this is placed under the tuner.
See if it's present, because without you always get the no ca found issue.
