Shelly 1L flashing fails
Closed this issue · 2 comments
I got three Shelly 1L devices from their Europe store (it was much cheaper than ordering from the US store). I went and flashed devices with Tasmota binaries. Flashing of the first two went well and without any issues. I cannot flash the third one even though I used exactly the same steps. I connected Shelly to my home network but when trying to flash a new binary (cut & paste of the URL with updated IP address of the Shelly device), it does not flash it. It gives me the following message in the browser:
{"status":"updating","has_update":false,"new_version":"","old_version":"20201014-165335/1244-production-Shelly1L@6a254598"}
It does not flash a Tasmota binary. I can still go back to the device and get their original GUI interface. Let me know if you want me to collect any additional data before I used expose pins and USB programmer to flash the binary.
An update; factory reset of Shelly 1L did the trick. I did manage to flash new binary after doing factory reset and, while flashing, got a proper message in the browser:
{"status":"updating","has_update":false,"new_version":"20201228-092147/v1.9.3@ad2bb4e3","old_version":"20201014-165335/1244-production-Shelly1L@6a254598","beta_version":"20210122-154623/v1.10.0-rc1@00eeaa9b"}
Sorry about opening the issue but, hopefully, this might help others if they experience similar problem
Factory reset prior to flashing fixed the issue
