I would like to share what worked for me after downloading endless software programs, to try and remove write protection
Try this one out
Just copy and past it into your Browser
You will have a winrar, winzip ect… pop up
Unzip to a folder on your desktop
Unzip the zip file, and with your usb flash drive plugged in, run the program
In my case the end result was format failed, I closed the program removed the usb flash drive and then plugged it back in
then windows asked me if I would like to format this device, the windows format WORKED YES YES YES BABY
The flash drive is as good as new.
I hope this helps someone.
