Wemos D1 R1 Clone doesn't run the sketch, all built-in LEDs off

Other Hardware 3rd Party Boards

Hello.
I'm having an issue with a Wemos D1 R1 clone board. My PC detects the COM port normally, Arduino IDE uploads the sketch normally, but, in the end, near seconds after the "Leaving...
Hard resetting via RTS pin...", the board simply turn off all built-in LEDs and the code doesn't work. I don't have a multimeter here, but, I saw D0 (GPIO3 and RX) and D8 (GPIO0) are the only pins that have some type of output. Monitor serial prints an ununderstable message.

Detail; when I press RESET button, the LEDs fastly turn on and turn off once.

Did I lost my board?

If it's being detected as a COM port, and you can upload to it, and you're getting the boot log at the oddball baud rate (74880 baud, IIRC), the board still seems to be, at the worst, mostly alive. Without seeing your sketch and a schematic, it's not really possible to say much of anything else.

Thanks for reply.
I set baud rate and Serial Monitor says: " load 0x4010f000, len 3424, room 16

chksum 0x2e

load 0x3fff20b8, len 40, room 8

Do you have idea what this could be?

For exame, I wrote a little skecth that uses a RGB LED module for testing.
The LED doesn't even turn on.

int ledr = D4;
int ledg = D5;
int ledb = D6;


void setup() {
  pinMode(ledr, OUTPUT);
  pinMode(ledg, OUTPUT);
  pinMode(ledb, OUTPUT);

}

void loop() {
  analogWrite(ledr, 255);
  analogWrite(ledg, 0);
  analogWrite(ledb, 0);
  delay(100);
  analogWrite(ledr, 0);
  analogWrite(ledg, 255);
  analogWrite(ledb, 0);
  delay(100);
  analogWrite(ledr, 0);
  analogWrite(ledg, 0);
  analogWrite(ledb, 255);
  delay(100);
  analogWrite(ledr, 0);
  analogWrite(ledg, 255);
  analogWrite(ledb, 0);
  delay(100);
}
