I ordered Xiaomi mini router and nano (youth) routers from Aliexpress. Now ugraded OpenWrt to mini. I don't wan't to open nano, because I am not a HW guy.
I opened xiaomi nano firmware fs and seems that there is /bin/flash.sh file. Is that common OpenWrt file or specific Xiaomi file? Maybe this file is called from router settings page?
Maybe it would be possible to modify flash.sh script in a way that it accept PandoraBox-ralink-mt7628-xiaomi-r1cl-squashfs-sysupgrade-r1468-20151001.bin file.
flash.sh file:
#!/bin/sh
#
. /lib/upgrade/common.sh
