Remove Write Protection from USB

My flash USB is write protected and I've tried every possible methods I've encountered over the internet, to get rid of this.

Accessing the usb is not working. Format from my computer, is not working. Clear attributes with DiskPart is not working (can't be cleaned, Current Read-only State is Yes but Readonly is set to false...

With Disk Management, I can't delete the partition...

Is there any other method... With a specific software or somehow?

Edit :

The USB came with no particular drivers, it's a generic one I believe, that installs and that's it. I tried this on Windows 8.1, but it doesn't work as well on Windows 7.

These are the details extracted with Flash Drive Information Extractor :

You need to discover VID PID of yours flash drive. You can do this with help of FlashGenius or CheckUdisk etc. Here is a page with all of this utility http://flashboot.ru/files/vidpid/

Then go to http://flashboot.ru/iflash/‎ and search for special utility for your flashdrive. Simply you need to re-flash your USB flashdrive controller.
