I have demoboard with STM32F417 and ST-Link v2. After some software fault, read out protection was activated. STlink utility print 

20:07:57 : Connected via SWD.

20:07:57 : Device ID:0x411 20:07:57 : Device family :STM32F4xx20:07:57 : Cannot read memory!                  Disable Read Out Protection and retry.What I mast to do to disable read out protection. I can't to do full erase of chip with the same error:

ST-LINK_CLI.exe -c SWD UR -OB RDP=0 WRP=0xFFFFFFFF -ME

Take any other HEX file and programe it. It will remove read out protection
