Unable to wake from DeepSleep about badgy HOT 4 CLOSED

No, it's not game over... you have a delay in there of a second, and the boot up from sleep also takes some time. The quick way will just be a case of trying to upload your sketch to the board, and timing the off/on right so it (the USB 2 Serial chip) catches the ESP8266 in it's boot up and sketch loading state. What revision board do you have? You're not going to damage the chip or board, just keep pressing upload, and trying different timings from when you can see the Arduino IDE compiling and turning the badge off and on. Unplugging the USB from your computer may be easier than fiddling with the slide switch too.

A longer and harder way would be to manually upload some code to the ESP8266 using some Dupoint cables and connecting up power, ground, RT, TX and setting the GPIO appropriatley. But you would need an external serial programmer, even a spare Wemos D1 mini or Node MCU would do. As you have spotted in your link, the pins would need to be:

UART Download Mode (Programming): GPIO 0 - LOW, GPIO 2 - HIGH, GPIO 15 LOW.

This will force the chip into programming mode when you power it up and you are not relying on the Badgy USB2Serial chip catching it in time. Then you can upload at your leisure.

sorted??

Have you kept the OTA Sketch upload part from the example sketches? This is where you hold down the centre button of the joystick to get it into upload mode from a web interface. If you do that, it will keep the ESP8266 alive while it waits you to upload a BIN file. Ignore that, but now the ESP8266 is no longer running the sketch so will be able to be flashed. Can you post your whole code to this to see at what point you have added the sleep part?

Unfortunately, I didn't keep the OTA Sketch upload section (as I said, stupid).
The sketch was something like the below code... is it game over to my badgy? :(

GxIO_Class io(SPI, SS, 0, 2);
GxEPD_Class display(io);

void setup()
{
  Serial.begin(115200);
  display.init();
  myfunc();
}

void loop()
{
}

void myfunc()
{
  delay(1000);
  ESP.deepSleep(1 - 1000000UL);
}
