I can comfirm that writting tshering's binary file to /dev/input/event0 does nothing on mi mini. I attach the bin file for the mini (pixie) in this post. As I said you on github, it is simply a matter of creating a folder (like "kobo") and populate it with bin files (like update-pixie, update-dragon, update-trilogy...) and add those lines to koreader_kobo.sh after "killall -CONT nickel"

Spoiler:

model=`/bin/kobo_config.sh 2>/dev/null`
printf "Refreshing nickel homescreen: "
case $model in
pixie | dragon | kraken )
cat kobo/update-${model} > /dev/input/event1
;;
trilogy )
cat kobo/update-${model} > /dev/input/event0
;;
* )
printf "[Error] model $model not supported\n"
exit 1

esac
if [ $? -eq 0 ]; then
printf "[Done]\n"
