So after I have uploaded all the Lua scripts needed and the chip become a small system, is there a way that I can set the NodeMCU to read-only so nobody can upload or download the scripts from it unless re-flash the firmware? Anybody any idea? Thanks!

For the esp8266-12 I created a file blank1024kB.bin. The one I uploaded 4x from address 0x00000, 0x100000, 0x200000 and 0x300000. Then reflash firmware.
