Seems it was my big mistake to erase an eMMC storage… Now I can’t boot even with SD card. 
The only source I found describing how to make a bootable SD card is this one. But when I’m trying to boot from the SD card I’ve made according to the instructions in the link, I’m entering into the endless reboot loop. The log of this is here - http://pastebin.com/wv57u66z
