Hello,
I tried several tutorials to flash the original firmware on my wemos D1 mini with no success. No blue led and only the message ets Jan 8 2013,rst cause:2, boot mode:(3,6).

I tried different versions of the FLASH_DOWNLOAD_TOOLS V.2.4 and V.3.6.5.
V 2.4 gave me errors, none with the V 3.6.5.

The Wemos I use : https://fr.aliexpress.com/item/D1-mini-V2-Mini-NodeMcu-4M-bytes-Lua-WIFI-Internet-of-Things-development-board-based-ESP8266/32681374223.html?spm=a2g0s.9042311.0.0.27426c37hSvF4D

I don't know what to do next except trashing my wemos and buy a new one.

It has been a while since I flashed an ESP with default (AT) firmware, but the settings *seem* to look fine (except I used regular 32MBit flash size instead of 32MBit - C1).

Have you tried a different USB port (preferably on the back of your PC)?
Have you tried flashing at a lower Baud rate?
Is this is virgin Wemos or has it some mileage on it (from previous projects)?

Just some things that cross my mind.

Have you tried flashing a simple LED blink sketch using the Upload feature in the Arduino IDE?

Try this, it defines the correct pin for the D1 mini:-

Thanks for your help.
Different port and cables tested = KO
Lower baud rate tested = KO
Not virgin, I use to host on it the McLightning script for 3 or 4 months.

Anyway in an excess of rage I fried my WEMOS. Now it is completely broken so no more problem.
