[Android Head-Units] Filipeknot:
Nothing happens...

The Phoenix suit detects the HU without the short, and asks to beging flashing, and 1 second after the HU disconnects from PC...

Shorting the resistors changes nothing... Two of them when short does nothing, neither the connection with PC... With the others, HU connect with PC at least and disconnect after 2 seconds.

With energy ON, device manager show me a yellow interrogation device.

With energy OFF (Only USB) the Phoenix suit detects HU and start flashing, but it does nothing, and gives me an error after 15 seconds.

EDIT: Now and i don't know why, with Power ON the device manager show me this device USB DEVICE(VID_1f3a_PID_efe8) but Phoenix Suit does nothing too...

EDIT2: Trying to flash with PhoenixSuit gives me this on Putty:
