I am a new Tasmota user (I have a few Shelly modules that I managed to flash OTA) and I wanted to add the Sonoff ZBBridge to control zigbee modules.
I followed the tutorial from here to flash Tasmota.
Everything seems to be good, and I receive the “Flashing successful! Power cycle the device” message, but when I disconnect the ZBBridge from the USB to TTL dongle and power it through micro USB, there is no tasmota_xxx WiFi network. The ZBBridge seems to have 2 leds (one for WiFi and one for Zigbee) and only the one for the Zigbee part is on when flashing or when powered through the micro usb (green light).
I also tried tasmota-pyflasher and got the following output :
Command: esptool.py --port COM3 --baud 115200 --after no_reset write_flash --flash_mode dout 0x00000 C:\Users\User\Downloads\tasmota-zbbridge.bin --erase-all esptool.py v2.8 Serial port COM3 Connecting...

Unplug/replug or reset device to switch back to normal boot mode.
Everything seems good apparently, but the problem still persists.
I tried to debug the boot with putty but nothing appeared on the console.
Is it possible that I broke something when I soldered the wires to the PCB (knowing that I have no experience in soldering)? Even if both flashing programs seem to tell that flashing was OK?
Any ideas on how to debug this?
