I just updated the firmware of my "LS-8P Addressable LED Strip Controller (Digital Microphone Built in)" to official WLED_0.15.0_ESP32.bin (sha256: 9943fb09592dab19ff5e482b1a03f284927ddf64af5d74fedac9eea23de5e408).
Now it doesn't boot any more. It seems dead. No relais click. No LEDs light up. The button does not do anything.
Did I use the wrong version? I'm pretty sure I came from WLED_0.14.4_ESP32.bin, so same architecture. I left the SR fork of WLED behind already a year ago.
If I need to flash using a serial adapter, which firmware version should I use? Does the controller have easily accessible pins for flashing?
We tested it and there is no problem. Please make sure your firmware is correct. The link below is the factory default firmware.
