It can't boot now, can anybody help?

[tueht]

I followed the serial instruction, but at the flash step I didn't know what todo, so I copy the content of sdcard and sdcard_update to the sdcard, run dstar now when I power it up, it says can't read tf_ update.img and kernel.img, this is the captured log (sorry this might be not 100% correct since I captured it can copy the text from the image.
