STM32F030K6 Core is Locked

[developeralgo222]

I have 2 x SMT Electric Feeders (Same Model --- HGWC Yamaha YMH-EF8-000 8mm) with STM32F030K6 MCU that are having issues with Core/CPU lock up.

NOTE: I know that when the STM32F030K6 chip is configured for either RDP Level 1 (Read Protection) or RDP Level 2(Chip Protection), *ANY* attempted access via JTAG/SWI/SWD will lock the core. 

This is by design, and it is how RDP1/2 prevent outside access to FLASH and RAM. 

The programmer is trying access the chip after reset, which triggers the lock. 

This is normal behavior. You always need to power cycle after programming RDP1 or RDP2.

i have tried everything to unlock Core or CPU with STM32 Cube Programmer using ST-LINK V3 Set (Also tried ST-LINK V2 ) but in vain. I have several SMT electric Feeders which are working fine but i don't have the original .bin file from the manufacturer who seem to have gone out of business. No response from them anymore.

My intention is to extract or download the .bin file from the flash Memory from the working SMT Electric Feeders and use it to flash the 2 locked SMT Electric Feeders with STM32F030K6 Chip. so that i can get them working

Any Help on how to Unlock the Core and reflash the STM32F030K6 ?
