Hi,
Did you solve this? I am the exact same situation. After issuing AT+IPR=57600, the ESP actually worked fine with a lot of commands. Until I did a power cycle.
Now I am stuck in exactly the situation you describe.
I can see the boot msg at 74880, but when I switch the terminal to either 115200 or 57600, nothing happens. No response.

Hope someone can help.
