How to remove write protection from usb flash-drive?

So 7 years laters, it still happened. It’s a 3 months-old 32GB Sandisk Ultra USB 3.0, just being used several times on the first month.

I’ve had enough of this brand, I’ll just throw it to the trash can rather than RMA-ing it and receive another unreliable stuff.

I’ve banned Sandisk’s memory cards in the past as they kept on dying, now I’m banning the whole brand. My Sansa Clip+ had instability issue after only 4 years of very light use, now this!
