Problem in reflashing D1 mini

[pisabe;;]

Hello all,

Some time ago, using Arduino IDE, I flashed a D1 mini in order to try something that did not really work and that I don't care about any longer.

I tried to reflash the same D1 mini using Esp Easy Flasher. I always get the same error regardless of the bin file I am using among the following ones:

- blank_1MB.bin
- blank_2MB.bin
- blank_4MB.bin
- ESP_Easy_mega_20200913_test_ESP8266_4M1M.bin

Note that previously, I was able to successfully flash a different D1 Mini using the latter bin file.

Anyone can give me clues about the problem I am experiencing now?
