Switching on debug - https://github.com/esp8266/Arduino/blob ... bugging.md

Please see below sample settings for debugging of httpUpdate

Note you need to set both "Debug port:" and "Debug Level:".

The process of OTA download by a module takes some time. Maybe you were not patient enough. Switching debug on should make the process visible. Also I would add some Serial.print() statements in your code to see if it runs and were it is at.

If I use standard httpUpdate.ino sketch and modify it in attempt to upload your bin:

Code: Select allt_httpUpdate_return  ret = ESPhttpUpdate.update("http://u.synaptrix.com/spooky.bin");


I see the same log. Basing on this log, OTA update is successful, module is reset and then nothing other visible happens.

If I do the same with:

Code: Select allt_httpUpdate_return  ret = ESPhttpUpdate.update("http://iotappstore.org/blink.bin");


Then the log is almost identical but the LED connected to GPIO2 starts blinking.

Could you do the same test and post results?
What is your module type?
Does it have LED connected to GPIO2 and have you checked that it works?
What settings do you have in IDE for uploading?
