Quad Cortex can not boot up

When I changed my preset to a factory preset, screen just not respond. Then screen turned black, so I disconnected power supply and try to reboot. But it didn’t work, lights are flashing and there is nothing on screen. Do you have any recovery method or recovery software?

A while ago I had the same problem (flashing without booting). Nothing helped but opening a support ticket. They have sent me immediately a replacement unit. This one now works well so far.

I already fixed this problem. I opened backplane, reset tf card and pressed a little blue button few times during booting process. Then I saw welcome screen. Now it’s totally functional.
