So my friend kindly lent me his flash drive once mine had died a painful death however when I plugged it in we found out that it was write protected, I can't format it, regedit does not work and I have tried through command prompt, I have tried pretty much every method on Google and nothing works. Any ideas?

Try formatting it in another PC. I've had this same issue come up and using my buddy's laptop fixed it. I can't explain why.

No I can't see a lock, don't really want to to open the casing either

This happened to me before. I had to use some 3rd party software to unlock it and the files contained on it were a bit corrupted. I was copying data to it and all of a sudden it becomes write protected mid copy.

 

A few months later down the line, I figure I give that flash drive another chance and low and behold, the thing goes back into write protected mode mid copy. A 32GB flash drive that write protects around 6GB worth of data. Hate to break it to you, but that USB is a dud. Most likely it reached its write limit and goes into read-only mode for that reason. Pick up another drive, it's not worth messing with that one.

I think I was coming to that conclusion, I have already ordered another one, thanks anynway
