Help can't update firmware via zune

[emil.sulistya]

Hello, i just get a new lumia 800

OS version : 7.10.8773.98
firmware : 1750.0805.8773.12140

the phone prompted my that there is an update, so i connect it to my pc( windows 7, x64) and fire up Zune.
after clicking update now, update will fail with error 8018121C1 after step 5 when Zune trying to reboot phone.

this error showed up after the phone rebooted to WP7. Before it boots to wp7, for a brief moment, my windows pc was trying to find driver for Nokia DLOAD, but cant find it.

anyone experienced this before ?


thanks
