Hi @Bárbara, thank you for the step-by-step walk-through. I've owned an X-30 for a little over a year now, and it's only today that I realized I needed the flash . . . and it's not working. No matter what I pressed/ toggled, nothing seemed to work. I was this "close" to hitting "Reset" when I stumbled into this site. The flash is working now! Happy New Year!
