If clearing the history on the phone does not resolve the 800705B4 error. There is now a Windows Phone Support Tool available that should fix this problem. More info on this tool is at:
I've yet to see the update with my Samsung Focus - Guessing that the issue hasn't truly been resolved yet.
To help dig deeper, if you are running into the error 800705B4 during phone update, could you please be sure to provide the following details...
It would also be helpful to know the exact steps you went thru...
Could you please unplug all non-essential devices, such as webcams, game controllers, and printers, and then try to run the Windows Phone update again?
Thanks for posting.
