I have no idea which address ranges to flash and get an error message "invalid head of packet <''>

Most users do not know that using Arduino IDE to program an ESP8266 completely overwrites any firmware (AT, LUA, NodeMCU) that the ESP8266 shipped with... Any hiccup caused by noise, power spikes/droops, will interrupt the Arduino load process. In a perfect world, just trying another ArduinoIDE download should "fix" the issue. But, blank firmware has been indicated by others when things go very badly. But, it is your module ... Do what you wish.

thanks for your answer.
I had exaxtly the same problem with instable ZDP link.
I do not understand, why status of EEPROM/FLASH segment, that is not used by actual running code has an effect on code execution.

Nevertheless, filling up complete memory with 0x00 before flashing code works!

Thank you again.
