I just got my Entina Tina2S, and first thing I tried was making sure firmwares were up-to-date. Due to some confusing instructions I think I tried to update the wifi firmware with the machine firmware. Now the wifi module does not work (Wifi device error) and in wifi info everything is "unknown".
I can flash the machine firmware (wfm) with the weedo flasher, but i can't find a way to flash the wifi firmware (efm) via usb..
Any help?
