nodeMCU binary???

[Jester]

I have a nodeMCU board that was working with an Arduino script.  Win7-64 and Arduino 1.8.15
The module is an ESP8266MOD I think that translates to a ESP8266-F?

I can no longer upload scripts, the com port appears to be working, but my best guess is that the nodeMCU has lost the boot loader (no flashing LED just dim blue LED).

I don't think the CP2102 driver is the issue and the power supply appears to be fine. When I connect a terminal it recognizes the port but there is no response on the port, I have tried 9600 as well as 115k baud.


I think I should try reloading the factory binary, using nodeMCU flasher, I'm just not able to find the binary anywhere.

Any assistance is welcome.
