Blank screen emmc flash


I tried to install ubuntu over android using the sdcard method and seem to have a blank screen now, cannot get it to boot at all. And it ist showing up in the usb burn tool?


Solved, here is how
Step1) set up serial
Stem2) create a flashable sdcard for android
Step3) insert sdcard
step4) erase emmc
after reboot, it will automatically start the upgrade process
