Hi sorry if am posting on this a wrong section(new guy).My Sandisk Ultra 16GB Usb 3.0 pendrive got write protected error last day I know that it isn't done by any viruses (no software issues i checked the normal route tried the registry fix that kind of things).
Then i find about the reprogramming the chip inside pendrive can recover the pendrive.
The information from Chipgenius is
