@esp8266 , ich habe jetzt noch einiges probiert, bin aber noch nicht zu einer Lösung gekommen. Als ich das Flash-Tool benutzt habe, ergab sich im Anschluss eine Reboot-Schleife. Deshalb habe ich dies auch noch über das esptool probiert:

Aber dies führte ebenfalls zu einer Reebot-Schleife:

Rebooting...
Die einzige Methode, wie ich es überhaupt hin bekomme, dass der ESP auf Port 80 reagiert, ist der Web-Installer. Aber dort kommen dann halt die Meldungen aus dem letzten Post. Für weitere Hinweise wäre ich sehr dankbar.
