I don't know where the bug or bugs are.

Step: Flash SW102 firmware using bootloader

The bootloader 0.19.12 is located on the SW102. (https://github.com/OpenSource-EBike-firmware/SW102_LCD_Bluetooth/releases) The battery and the SW102 are connected. The display does not light up when the power button is pressed. Even if you press and release the M button and then the On / Off button for 8 or more seconds, the SW102 display is not shown to me in the nRF Connect app.

Tried another solution: I had disconnected the battery and connected the cable to flash the firmware with the TSDZ2. I hope the display will turn on. Now I was thinking that the firmware may need to be flashed on the TSDZ2 first.

Now I wanted to flash the firmware on the TSDZ2. Before doing this, save the original files (program and data) as in the first video. Battery disconnected. The original display was reconnected. The ST-Link V2 is connected to the motor and laptop. The original display cannot be turned on. I've tried Read All Tabs with the STM8S105x4 or -6 but no success. See last screenshot.

I checked the wiring for continuity with a multimeter. Everything OK.
