Mixer X1800 factory reset don´t work

Mixer X1800 factory reset don´t work, any solution?

Putting new update (re-update) should fix the problem (or at least overwrite all settings to defaults).

I’ve tried pressing back + FX Cue + TAP, and it’s flashing all the lights on the mixer, and it goes on and on, and it doesn’t stop. Restarting the mixer and continues to flash.
