OTA Firmware update failed - what did I do wrong?

[jschwalbe]

Hello! I have one of these "Eco" wifi plugs that I was able to flash with ESPEasy via USB TTL device. I used R120 and decided that I wanted to instead upgrade it to the latest available, R147. I checked the Main page which stated that I had Flash size: 1024 kB. So I loaded the new firmware (selecting the 1024 version with filename "ESPEasy_R147_1024.bin") and it seemed to load. The message was something like "Updating complete..". But when it rebooted, it hasn't come back online. It's not on my network & it's not broadcasting an ESP_0 network either.

What gives? Now just to see if I chose incorrectly, I tried the same method, but with the _512.bin filename on a different device. Same outcome.

Currently they are both sitting there, plugged into the wall, flashing the blue LED in a strobe-like pattern. blink-blink-blink about 2 blinks/second.

Is there a recovery mode, or a reset mode? Basically, is there anything I can do besides opening them up and reflashing them? Because that's a pain in the butt! AND, since I have a few other devices that I haven't tried flashing yet, is there any way to flash those via web that will work where these failed?

Many many thanks!

I have been strugling with a simmilar problem. I flashed the Sonoff and followed exactly the steps provided in a video.
However it didn't come back online, at least that is what I thought. I took another mobile phone and used a tablet and after a scan it showed up in the list. It might take a little while to show up, like 2 or 3 minutes.

Thanks, but nah - after 2 weeks it hasn't showed up on multiple iPhones and computers. It's dead, Jim.

Have you tried to do the flash again? What is the result of the flash if you do this again? I have been succesful by following this "step by step" video and using the CH340 USB to Serial adapter. (No Arduino) https://www.youtube.com/watch?v=fN_QKOW ... ubs_digest

It'll reflash but just didn't like doing it over WiFi.

If the flash was succesful it should not be defective. I had that idea too, until I got help from others here on this forum and it turned out that it was NOT defective.
