ESP8266 Community Forum

- Sun Jan 24, 2016 5:46 pm #39608 I have 2 ESP8266 (8 pin) chips. One of them is sending garbage values continuously. Had tried to flash it with esptool. But still no luck. Both red and blue LED are lit (without blinking). Is there a chance that the chip is damaged?

- Mon Jan 25, 2016 10:56 am #39658 Probably it's on a boot loop.

The only way to recover is to flash the original firmware.

If connected to the serial port at baud rate 74800, I think, do you make sense of the garbage?
