Not able to change rdp level 1 to 0 in stmf103c8T6

[mohamedehsan]

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

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.
