NanoPC T2 haven't boot to OS Selected

Charlie Nguyen
Dear All,
 I'm facing a problem with NanoPC T2.
 When I inserted my microsd card + case to boot slot of NanoPC T2, I hold
Boot and Power Button, But The scress just display a Penguins with two guns
and a text :" Wait For Update".
 I waited to long time but nothing happend.
 I try to power and press boot button so NanoPC booted to AndroidOS.
 I'm using s5p4418-eflasher-sd8g-20161117-full.img image to flash OS to
eMMC Memory.
 Anyone can help me troubleshoot this problem?
 Thank

Hi,T2 key programmer firmware we have updated, you can download to try, if
there is no system choice of programming interface, you need to check
whether there is a problem with the SD card, SD card 8G or more
suggestions. Press the boot button before power up, power supply is
recommended by 5V/2A.
