ST-Link v2 Cube programmer

[LesterC]

Hi all, new to this. I am trying to remove read and write protection. In the option bytes, I cannot change wrp-0 and wrp-1. The progress bar on the lower part of the gui says 100% but does not actually finish. when I check the live update box, I get a read failed message. Thanks in advance.

What chip is this?

What are you changing them from, and to? Perhaps change write protection on its own. RDP requires a full chip erase in some cases.

Screenshots of the error message are helpful.

Thank you! I was erasing older bootloader and installing a new one. I got it figured out though. I just downgraded the cube programmer to an older version and it worked.
