k800i does not go into flash mode

[etel]

hi,
thanks for replies,
But my problem is for some reason my PC does not detect the k800i.
i will explain what i am doing.
turn off the phone.
remove the battery.
place the battery again.
press C button and while holding I plug the USB cable to the PC.

PC (winXP) does not detect any new hardware to install the driver. I searched from device manager for new hardware without any luck.

However, my PC detect the phone in normal mode.

How can I confirm whether the phone is turning on the flash mode.
thanks
