Install from SD does not always work on every device. Xiaomi's MUI is not friendly to all modifications.
For the installation from the internal memory goes basic package.
I've installed all the forum versions from the internal memory on my friend's Redmi 3 Prime and 5s (it is possible that it can also pass install from SD, but it's much easier and safer for me to do it from internal).
So, you did not follow the instructions carefully :smile:
From your screenshot - you (again) made a mistake. When installing from an SD card, depends if Modemakias or miochacha version
- folder does not go to root. Read that topic/exact post again.
- Or: In this case don't forget to add in your sys...... in the "llinked_root_list" path...... your extSD
extSD - exact name of SD card, how system see it. For android 6.0+ usually in form xxxx-yyyy
So, yes, lack of reading :D
