I did change baudrate of esp-07 module to 1200 trough AT-command with following command :
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
