Bosean FS-600: Can't flash

[catgirl2137]

Hello
I recently tried to flash RadPro 2.0 to a Bosean FS-600 geiger counter.
Even though I followed all the guidelines, the process errored out while creating a bakup.
Because this is my first time dealing with STM32 based devices, I have no idea what could be the reason for such error, and I would very much appreciate any help.
Down below is a screenshot of the error I'm getting

and a photo of the circuit board.


It differs from the one in the example by capacitor/resistor placement, but the IC seems to be the same type.
Thank You in advance!

First, check the electrical connections with a multimeter.

If it still fails, try keeping the ok/power button pressed while flashing, with the main battery connected.

Thank you for your fast response!
Already checked the connections - all ok
ST-link V2 driver is installed
Tried flashing multiple times while holding power button, both with and without battery - same result

Unfortunately I can't help you any further.

Is there any chance of an IC pin that has to be pulled up or down to enable programming?

I don't own a Bosean FS-600. Perhaps someone with such a device in this forum can help you any further.

I have 3 Models of FS-600 and i can confirm there are no bigger problems to flash the device.
Sometimes you have to try a second time or unplug the USB programmer and plug it back in.

Show a photo of how you connected the programmer to the 4 pins of the programming header. Sure, all is correct?
Does the FS-600 start when you connect the programmer?

For the FS-600 look here too: https://www.geigerzaehlerforum.de/index.php/topic,1068.0.html

For the FS-5000, the device boots while connected to the STLINK and then cannot be flashed anymore. I can flash it reliably without issues if I start the flashing process directly after connecting the STLINK to USB. If I wait too long, it won't work anymore.
Maybe it's a similar issue on the FS-600?
