STM32F105 Read protection issue

Hello guys. I was trying to read the code out of a STM32F105RBT6 using a SWD circuit and the STMprog software but the code was ''Read protected'' and I couldn't bring it out .

Can you guys give me a help or suggestion on this? Is that possible at all? Or is there probably a professional programmer out there capable of unlocking the ARM chips?

Cheers.

The methods provided by ST to remove the read-out protection also mass erase the part.

The serial port system loader can be used to do this, and probably the ST-LINK tools.

since Clive is your brother, I hate to interfere in a family affair. However what is difficult? all tools known too me has an 'erase chip' command.

If there was a (relatively) simple way to bypass the read protect, why would the manufacturer bother implementing read protection. The only reasons I can see for 'breaking' a read protect are dishonest.
