Lost the device access because of "bmode emmc" command

i just purchased a new e ConnectCore 6 SBC development board 1.2Ghz board and it was going to the auto boot screen.
But then when i copied the yocto files from your website (ftp://ftp1.digi.com/support/digiembeddedyocto/2.4/r2/images/ccimx6sbc-installer.zip) and put into a SD card and typed the “run install_linux_fw_sd” command it said it dosent know install_linux_fw_sd.
So i just tried TFTP but that also dint workout well…
So i just typed a “bmode emmc” and i have lost the device now… i dont even get the autoboot screen… How do i recover my device?
