Windows Vista Update error code 800F020B - how to solve?

I had the same problem, but it disappeared after some time.

try to attach the device before the installation and leave it attached during installation

but how do i restart the update again? when i try checking for new windows updates it reports there to be none. my smartphone is no longer detected by mobile device center...

I do not know the solution, but you can try to uninstall Windows Mobile Device Center (Start > Control Panel > Uninstall a Program) and install it again. Download is here: http://www.microsoft.com/windowsmobile/devicecenter.mspx

There is a new version 6.1 on the mentioned Microsoft page (I am running v. 6.0), maybe it helps.

I had this error message and what resolved this was to leave device plugged in as you installed updates.

Jupp, installing with connected device works

Thanks for the tip that BB needs to be connected. I happily solved the problem of not being able to run the update since it has disappeared. I connected the BB and ran the BB desktop manager, and then ran windows update, and the update re-appeared.

it didn't worked in my hp dv6 !!!

Yeah plugging in the device and retrying the download works. Here are the details on my issue.
