Blue LED on, stuck on booting BIOS

I Change the memory setting to duel channel, then reboot the RockPI X. Its now stuck on booting into bios. When I plug in the power, nothing display and the blue LED is on.
I am getting worry, the RockPi X is my birthday gift from my girlfriend.

Is my rockpiX dead? Can anyone help me?
Thanks and Help

Seems to be the same problem I have, see topic: Rock Pi X Wont POST

You can try the blind reset trick mentioned there, for me this unfortunately did not work. If it does not work for you too your board is indeed dead and you need a special tool to reprogram the BIOS, also mentioned in that topic.

thanks for your help, will try the reset trick tonight
