Magic Home RGBW Controller

Hi,
nice Forum.
Is it possible to flash from tasmota to WLED ota? Or do I have to open that tiny box again?

I tryed this things:
“Downgrade” to tasmota mini image.
Then tryed to flash WLED_0.11.0_ESP8266_1M.bin and WLED_0.11.0_ESP8266.bin thru ota (tasmota integrated webpage)

Thx
