With your USB drive plugged in, launch a command prompt. Do this by searching for cmd.exe in the Start menu (or Start screen in Windows 8). In Windows XP, click Start then Run, and type cmd.exe in the box.
NOTE: you may need to run Cmd.exe with administrator privileges if you see an "access is denied" message.
To do that, right-click on the shortcut and choose Run as administrator. In Windows 8, simply choose Command prompt (admin).
Now, type the following, pressing Enter after each command:
diskpart
list disk
select disk x (where x is the number of your USB flash drive - use the capacity to work out which one it is)
attributes disk clear readonly
clean
create partition primary
format fs=fat32 (you can swap fat32 for ntfs if you only need to use the drive with Windows computers)
After following every step one by one this finally worked for me. I had attempted to burn an ISO image to my Toshiba usb 3.0 and it became write protected in the process $65 saved.
What I have read and I don't have the technical details it will format on a low level flash process, don't quote me..
I tried the unlocker program from Filehippo and Malwarebytes fileassassin, neither worked. Hope this helps someone else!

Forgive me, edit me, remove me if I'm wrong here. Readers should be WARNED/ADVISED that the "CLEAN" command will remove write-protection, while also wiping ALL user/system data and all partitions.
