when hold boot key then bootup phone, device will into flash mode.

plug on computer, it provide a usb 1.1 device:

it look like flash mode for this phone :)

it use generic usb serial driver on linux (not working, need capture usb data from windows) :

modprobe ftdi_sio
echo 1782 4d00 > /sys/bus/usb-serial/drivers/generic/new_id
