I have four identical NodeMCU boards from ElectroDragon. One of them, I used to follow Neil Kolban's video tutorial on programming. Unfortunately, I bricked the device. So, I went to NodeMCU.com and downloaded the latest release of their firmware. I have that loaded and it does come up stating:
NodeMCU 1.5.1 build unspecified powered by Lua 5.1.4 on SDK 1.5.1(e67da894)
lua: cannot open init.lua
So, I know the device is no longer bricked. But, I want to copy the binary image from one of my other devices back to this one so it states:
AT version:0.40.0.0(Aug 8 2015 14:45:58)
Ai-Thinker Technology Co.,Ltd.
Build:188.8.131.52 Sep 11 2015 11:48:04
Like all the others do. Is there a simple way of doing that?
