hi, 
I'm using stmf103c8T6. Recently it got RDP enabled while trying to flash a program. ever since then I'm not able to connect through cube programmer or cube ide. I tried to mass erase and write RDP=0xaa through stm programmer cli. all though I'm getting "mass erase successful" and "option byte successfully programmed", when I try to display it again it's still showing RDP enabled. I tried different boot mode also while trying to set the RDP but still not working

kindly help me to find a solution

Hello @mohamedehsan 

Based on the other discussion you have, your ST-LINK7v2 is a clone with probably a fake STM32F103C8T6. ST resources are only dedicated to supporting genuine ST products. We are not committed to ensuring that clones/fakes products work properly with the firmware we provide.

As stated in your previous post, you do not have a genuine programmer. Your target chip may also be counterfeit. There are no guarantees that non-ST hardware will work with ST tools.
