Installing LEDE on Xiaomi MiWifi mini

Hello,

I'm trying to install LEDE 17.01.4 on to my Xiaomi MiWifi mini but I can't find the factory image. Could someone give me some instructions on how to install LEDE on this device?

Factory image is not needed.
There are full instalation instructions here:https://wiki.openwrt.org/toh/xiaomi/mini

Well I should have said that I tried installing that way but after flashing the sysupgrade.bin, the router led starts blinking red. Which means that it can't boot.

edit:

Well, stupid me just had to wait till the led stopped blinking. I din't knew that LEDE changed the led color to red. Thanks anyway for your help.
