If you’re running into error 800705B4 “The timer ran out on what we were trying to do”, when updating your phone, it may help to temporarily delete media items from your phone (like music, videos, pictures and podcasts) and try the update again. But before
you delete any media from your phone, first sync your phone with your PC so you can later sync your media back to your phone.
If removing media content doesn’t help, you can try removing apps from your phone and then attempt the update.
Once the update has been installed, you can sync the media back to your phone and reinstall your apps.

Mine is updating as I post. However, it seems the problem with the older version of the update was "fixed" by just skipping Step 6: Backup. There's no way that a backup was done in a few seconds that it took to jump to Step 7...
EDIT: The update failed with the same error as you (800705B4), but my battery level is under 50%. I'll charge it for a few hours and try again.
So... I get the error 800705B4 and I have tried the following, as the "Windows Phone Update Solution" page suggested. There was no specific solution for this error code, so I had to choose "I received an error not listed here."
So I tried:
rebooting phone, including removing battery for a couple of minutes
connecting directly to the front USB port port and not through my extension hub
connecting directly to a USB port on the back of my computer
All this was done with the original USB cable that came with the phone, with each step having no apparent effect on the outcome of the update.
My phone (Samsung Omnia 7 - on Three UK network; SIM unlocked) seems to remain stuck on the connecting to computer screen. I was expecting it to show the "connect to PC" image and then switch to the "do not disconnect" image, but rather just remained on the
So... My hopes for a certain fix on this update have been let down. Is this seriously that hard of a problem to get around?...
I simply plugged my phone in via cable with no previous relating steps, Zune detected my phone and came through that I have an update available, and I went ahead with the update. The phone reboots as step 6 indicates. Then when it gets to step 7, saying it's
installing updates, no progress is ever made (and the phone never seems to know it's connected - the computer does) and hence the timeout. The phone eventually reboots with Zune's step 1 of 2 saying so too and then states it has failed.
