Thanks for the reply...

 

Yup, I noticed the system date was incorrect due to faulty CMOS battery. So I re-did the installation this time to USB flash drive (30gb), but same result. Here's  the new installation log and my OC files.

It seems that a working option for me is to install High Sierra on an APFS formatted flash drive which I exactly did and was a success. I suspected that the latest build of High Sierra installer is forcing me to install it on the new file system. 

 

Now my problem is how to restore/convert the APFS drive into the HFS+ drive. I've searched google a number of times and I haven't found a  way to do it yet. There is a software called APFS to HFS+ converter by Paragon Software but it is no longer available at their site.
