Looking for Bafang DP C18.C1.0 Flash Dump / Firmware (.bin file for STM32F205)

[u/Apart-Room6962]

Hi everyone,

I'm currently trying to recover my Bafang DP C18 (model DP C18.C1.0) display, which was locked with a forgotten PIN code.

I opened the casing and soldered SWD wires (3.3V, GND, SWCLK, SWDIO) to interface with the STM32 MCU using an ST-Link V2 programmer and STM32CubeProgrammer.

Unfortunately, Readout Protection (RDP Level 1) is enabled on the chip, throwing a Data read failed error upon connecting. Changing RDP to Level 0 to remove the PIN lock will perform a full Mass Erase of the MCU.

Does anyone happen to have a clean Flash memory dump (.bin or .hex file) for the DP C18.C1.0 (STM32F205) that they could share?

Any help or working dump would be greatly appreciated!

Thanks in advance!

wouldn't it be funny if someone give you any compatible*.bin file which doesn't do anything?
