4 years ago To unlock it using the Arduino IDE click on Tools->Burn Bootloader after selecting an STM8 based board and choosing the correct programmer type (ST-Link V2).
The name of this menu entry is not self-explanatory, but I couldn't find any way to change it or to add another entry with a better name. I updated the description on the stm8blue page to point this out.

Hello, I have experienced some issues while unlocking the stm8s103f3p6 blue breakout board on Windows, the solution is simple and i think you may want to reference it on the guide for unlocking the MCU, in the hardware section (https://tenbaht.github.io/sduino/hardware/stm8blue/). On arduino IDE you cant tell if your MCU is locked or it's a simple connection problem, so its good to at least reference a "path" to solve the issue on Windows based systems where the users dont know how to use/or dont have bash cmds like Linux (me). You already know how to unlock it but here it goes for the ones who dont: If the board has write protection ON (Read Out Protection or ROP) you will need to install the STVP (ST Visual Programmer) to flash a new configuration that overwrites the Protection bytes and sets them off. To do so just do a simple registration on the ST website and donwload STVP. Install and open it > Configure ST Visual Programmer with Hardware(ST-LINK), Programimg Mode(SWIM) and Device(STM8S103F3)> select the "Option Byte" tab. Now the first item there is "ROP", put it OFF > Save the file as .hex > Import the same file > Program the MCU > and done. No more Arduino IDE errors. While using the STVP with a locked board you will receive a message saying its locked, so to test it just try to read it after the flash has ended.
And pay attention to Chinese ST-link V2, they come with bad or no contacts on some pins, test them all out.
And thanks for your great job on SDUINO.
