I tried to update WLED Firmware from Stock-Rom to 0.13.3.
First I tried with ESP8266 Version without success. Then I tried ESP01 Version with success but my device is bricked. I think, it should be ESP02-Version.
I opend the LS-4P and put my USB-UART-Adapter on it:
VCC to 3V3
GND to GND
TX to RDX
RDX to TX

Then I tried to get the ESP into flash-mode with a wired bridge between RST and GND.
Tried "Easy ESP Flasher" with following error-log:
espcomm_send_command: sending command header
[22.10.2022] espcomm_send_command: sending command payload
[22.10.2022] serialport_receive_C0: 52 instead of C0
[22.10.2022] warning: espcomm_sync failed
[22.10.2022] error: espcomm_open failed
[22.10.2022] error: espcomm_upload_mem failed
[2022-10-22] STOPPED due to 2 errors! (try reset on the unit, then start a new flash attempt)
Any idea how to "re-flash" with correct binary?
Remove the RST to GND jumper. The ESP won't flash with this jumper in place.
Press and hold the pushbutton when you apply power to the ESP, then release the button. You should be in the flash mode now.
You have to hold down the button for it to work 3.3 to 3V3
GND to GND
TX to RX
RX to TX
