I just received my pre-flashed 15W E27 bulbs ordered after they were supposed to be using standard firmware. I activated the first one, opened the Tasmota UI, and attempted to upgrade the firmware. It said it was uploading and the device would restart. The bulb turned off but never came back on again. The Web UI went to a page indicating it was on minimal and I should try to upgrade the firmware. I clicked on the upgrade button and lost access to the web page. The device dropped off my router and hasn't re-appeared. I've tried power cycling to reset it without success. I thought this wasn't supposed to happen with bulbs that are "Fully compatible with Tasmota official OTA server," but it seems like I've lost this one. I don't have the equipment to physically flash Tasmota. Is there anything else to try?
