After AT command to change baud for serial communication rate, my ESP-01 module has red led always on and not response to any other at-command. Any idea how to fix it?

There are various other topics in this forum about ESP cards dying after attempts to change baud rate. There seems to be a fundamental problem in this area of the AT command set. The only cure seems to be to reflash the module, assuming that the card exposes GPIO0 to allow this (or your soldering skills are good enough to get at that on the chip package itself). I need to try this on my own ESP-05, where I had this problem.

Red LED is signalization power supply only and is not controlled by software.
