Maximum Internal Storage of Xiaomi Mi 5s Phone Reduced to 8 GB from 64 GB

Good day all!

I am having a major issue with my Mi 5s. I installed a LineageOS (15.1 version) from MIUI 9. In the process, I think I have accidentally wiped something that caused the maximum internal storage of my phone to be reduced from 64 GB to just 8 GB. Is there any way that I can revert my internal storage back to 64 GB?

Boot your phone into fastboot mode and use this command:
fastboot -w

What exactly will happen after I've done that?

It will delete your complete storage and restores the partition tabel when it's necessary
