The flash chip is incorrectly installed, off by one pin.

it happened while desoldering the shield and I was to lazy to put it back :')

#22738 Hello,

I recently bought a esp8266 12e, with printings on it (AI-Cloud inside) that categorizes it as "fake" according to the descrption of the first message of this thread. And when I hooked it up to my computer, the only things that is sent back via serial is "NON GENUINE DEVICE FOUND!" that appears a few times when I power it up, and then each time I send a command, it just keeps printing the same sentence again and again while the blue led is blinking, only printing the number of letter I sent in the command (if I send "AT" it'll print NO, then if I send "AT" again, it will send "N ", and if I send rubbish like "ATTTTTT" it will just answer by "GENUINE", etc etc....).

Does anyone had the same issue? May it be realted to those "fake" chips?

#22742 First of all: calling the ESP-12e a "scam" seems to be one guy's oppinion, based on the marketing claims & difference (or lack thereof) compared to ESP-12 modules. So far I have not seen any credible reports that there are fake ESP8266EX chips being sold.
Also: why would a fake device announce itself as fake in such a way?! That would kind of defeat the point of producing fakes...
It is more likely that this message is produced by the FTDI driver in response to a knock-off FTDI USB to serial chip (google ftdi-gate).
