I would just like to update you all that the issue is fixed. After many days and days of trying to fix this problem, One day my Walkman just completely stopped working, it would not even turn on. I was so angry as I have only just bought the item. But I took out the Micro SD card and voila, it was working again perfect, I can even transfer music to the internal storage.

My Scandisk 128 GB micro SD card was bought brand new, but unfortunately has somehow become faulty in less than 2 weeks... Thankfully the issue has now been fixed, the only problem I have next is what SD card do I buy to replace it? I bought that SD card off eBay brand new, I think I will try Amazon instead.
