Sonoff 4CH flashing error

Trying to flash a Sonoff 4CH board with ESPHOME but keep getting the following error on esphome-flasher

“Unexpected error: ESP Chip Auto-Detection failed: Failed to connect to Espressif device: Timed out waiting for packet header”

-tried power off serial adapter and nodemcu pins
-tried swapping TX/RX pins
-not holding down GPIO0 does boot board on default firmware and connects to wifi so power should be fine from serial adapter as well

Anyone else had issues with 4CH or any other suggestions to try?

Try flashing with NodeMCU-PyFlasher and mode DOUT.

Also didn’t work
