- Sun May 17, 2015 5:37 pm #17693 Had the same problem, I could flash anything onto the ESP, but nothing would boot properly. I solved it by flashing back to the AT command set (v0.9.5) booting up and then flashing back to NodeMCU..

From time to time, I have to burn AT 0.9.5 and then back to NodeMCU to get my ESP-01 working again.
It seems to break on a regular basis after some burn/write/format cycles (I use always the same module for test purpose).

Yip. Same here. Looks like there's some form of flash corruption that is happening.
