Now go to the link posted and flash the phone the right way. Flashing two times the eMMC is wrong. Its normal to not boot properly in this scenario. First you flash the root without reboot then the eMMC.

!!!When flashing the eMMC content, always flash the FIASCO/Rootfs image and then flash the eMMC. Do not boot up the device between the two i.e do NOT use the -R parameter at the end!!!
