it sounds like you are intent of wiping and starting from scratch.
if so, use the Media Creation Tool and make yourself a bootable USB or DVD image.
then use that to reload Windows 10.
that will give you the 1709 version (the latest Creators Update) and 16299.15 build, then you'll need to do some Windows Updates to get to the latest 16299.192 build.
all the things you have tried and failed, have there been reasons for the failures, like error messages etc.
