By mistake i downgrade my OG from firmware 1.1.0 to 1.0.4. OG reboot and connect to wifi. But no way to update it to 1.1.0. i test with all release version from 1.0.1. No way to connect to my computer with USB cable. Push to the button when connecting to USB port, blue led blink one time and shutdown. The computer don’t detect serial port.
Is there a way to connect a USB/TTL dongle to the motherboard to reflash it ?
OG still connect to Wifi. I already test with a factory and wifi reset.

Depending on what version of OG you have, it may or may not have on-board USB-serial chip (CH340G). You can certainly use an external USB serial adapter to flash the firmware.
Before you do that, I am not entirely sure why OTA update doesn’t work: sure you downgraded to 1.0.4, but all firmwares support OTA update. Did you get any specific error message or something?March 16, 2019 at 1:46 pm #1491March 17, 2019 at 9:10 am #1494
Yes, your image shows that the board does NOT have a built-in USB-serial chip. If you have a USB-serial converter, you can flash the firmware yourself. Otherwise, send a support ticket and arrange for it to be shipped back to us, so we can flash the firmware for you.March 17, 2019 at 9:21 am #1495

Problem resolved by flashing OG with a little usb-ttl dongle 😉March 27, 2019 at 11:43 pm #1516
Sorry for being so late on responding — I was out of the country last week for an emergency trip. You are right that it basically just requires 4 wires: 5V, GND, TX, RX. Glad to hear that you figured it out on your own.
