Firmware update is not working

[javierdc]

Using latest firmware 3.7.6 when I try to flash a custom firmware, the tool does nothing even that the network connected does have internet access.

Also tried to manually send a POST request to ota_unlock and does not work.

All other commands works fine (on, off, info, etc.)

Similar problem. The OTA unlock even fails.
I was able to change to toggle the unlock on one device with release 3.6.0 but on a second device that I upgraded to latest official firmware there unlock request does not respond.

Try inserting the deviceid into the payload.
