I recently encountered a challenging issue with my Shelly RGBW2 device, and I wanted to share my experience in case it helps others facing a similar problem. After encountering a malfunction, I decided to flash the device with Tasmota to regain control. However, my ultimate goal was to restore the original firmware, which proved to be more complex than anticipated.
Initially, I tried using various firmware files from the official Shelly repository, but each attempt resulted in the device entering a fast reboot loop. Frustrated but determined, I reached out to the community for guidance. A user suggested a specific firmware file from a Facebook group, which I downloaded and attempted to flash using ESPTool.exe, Tasmotizer, and ESPEasy. Unfortunately, none of these methods worked, and the device continued to reboot rapidly.
After several unsuccessful attempts, I decided to take a different approach. I reset the device to its factory settings and carefully followed a step-by-step flashing procedure, ensuring that the GPIO0 and GND pins were correctly shorted during the process. This time, the flashing was successful, and the RGBW2 rebooted normally with the original firmware restored.
This experience taught me the importance of patience and thorough research when dealing with firmware issues. I hope sharing my journey can help others avoid unnecessary frustration and find a solution more efficiently.
