Maybe you can have a try with the latest download tool. https://www.espressif.com/en/support/do ... ther-tools

AT+UART_DEF=1200,8,1,0,0

but it didn't work any more :( .

I did change wiring to boot to bootloader and did change baudrate of PC-software to 74880 to saw boot log but module print unreadable (but formatted) log after restart, like this :
GÄZˆQ@@XdY…gÌQ+kCP@öoÔWJ5•V™DD
or
GÄZˆQ@@XdY•gÌQ;kCPPöÔWJ5•V™DT

I was changing baudrate to all possible values but it don't work.

I did try to re-flash module anyway but it wasn't successful.

What can i do to recovery my module?

Thanks
