Options darked in JOdin3 Casual I am trying to root my phone using JOdin3(as Odin does not work on Linux).

But some options are darked out as shown in the image below.


I need to select Auto reboot and F reset time for continuing.What should I do?

Also my phone goes into charging mode(shows the green charging bar) quickly after going into odin mode, so I'm unable to do anything.

 I had to use Odin tag because there is no JOdin tag.Please change it if you think it would be appropriate
According to the developer, those disabled checkboxes are not implemented. Source.

You can still proceed with the flash even if F. Reset Time is disabled / unchecked. There should be no problems with it.
