I have an ESP8285 which I succeed in bricking after issuing an AT+IPR=9600
I attempted a few tools to re-flash the chip but they all fail. The most information during the process I got by using esptool.py.
Here is the output of the command.

Any idea what could be done to fix this? Btw, I used the same tools and commands to successfully re-flash another 8266.
Thanks,
