ESP8266 stuck at 74880 baud

I still have the same problem.
My ESP8266-01 does not respond to AT commands, and at 74880 baud it sends the following message when resetting using its pin:

ets Jan  8 2013,rst cause:2, boot mode:(3,6)

What should I do? I have tried flashing it several times with different options... Nothing has worked.
