You can merge system partitions already, just install xiaomi.eu 5.11.19 two times via updater app. So, if you already have 5.11.19 installed on your Mi2S just install it again via updater app and you will see. Before install it make sure you have USB debugging enabled in developer...
Thanks for the info TE check @graw2, but still 504,4MB on the system. Then have to recheck something going wrong. Its cause USB debugging is disabled. Then reflash one more time via updater then become 1009,3MB.
So don't forget to enabled the usb debugging.
thanks for your great job..
