A new tool released by Microsoft is making WP7 user’s update errors much less of a headache. The tool (released on their support site) fixes the following error codes:

  • 800705B4: The timer ran out on what we were trying to do.
  • 80180080: We couldn’t update your phone because your operating system might be corrupt.

Several users (myself and David K included) were receiving the dreaded #800705B4 error, and I can personally confirm that this tool allowed me to upgrade from 7004 (release) to 7008 (PreNoDo), and ultimately 7390 (NoDo).

You can download the tool on Microsoft’s support site here. For those of you having update issues initially, let us know how it treats you.


  1. Well, actually I don’t have a bricked phone. AT&T is still “testing” the update for my Focus.

    I am wondering because I have a friend who bought the Focus unlocked and bricked his phone.

  2. Well, since Tuesday I had “unlocked” my Samsung Focus (ATT with a 32 gid microSD) – tired of all the restarts (though no screwed up micro-SD cards). I had removed the ATT code in the registery so the Zune software would push the 2 updates (Feb and March / pre-NoDo and NoDo). All that worked fine; the problem was the dreaded 800705B4 error code.

    I removed nearly everything from the phone, still no good – same error code. This morning I spotted this KB update for WP7. Worked like a champ!!! After applying this fix, Zune pushed both updates and both were successful. I now have a ATT Samsung Focus with an installed 32 SD card – no restarts so far. Also, everything they say about NoDo is true!

    Confirmed. I was able to run this tool on my friend’s phone and unbricked his Samsung Focus.
