Unable to complete synchronization on Blackberry with DTM 6

Here’s how I resolved a difficult problem with my Blackberry sync. Since I found very little in the way of solutions when googling this issue, I’m posting my efforts here in hopes that this helps someone having the same problem.

I returned my Droid Monday in anticipation of purchasing the new Verizon iphone. So I’m back to using my Blackberry Storm 9550 until the iphone is available for purchase.

I immediately had terrible trouble getting the BB to sync with my Outlook contacts, which was strange because I’d never had the problem before I’d switched to the Droid. I was getting an error code that is apparently very common: 0x80040fb3. Supposedly this indicates something is wrong with one of the Outlook contacts, buy that didn’t seem to be the case as I tried syncing with several different contact folders. Finally I updated the device to a newer version of the software, and that error code went away. Instead, I simply got the crytic message “unable to complete synchronization”. While a handful of my contacts were there, most were not. Since my business is a mobile one, it’s critical that I have my contacts with me all the time.

I tried two different Windows installations, two different versions of Outlook (2007 and 2010), two different versions of the BB Desktop software (5 and 6), in all possible combinations. (I even tried using Companion Link to use Outlook 2010 with DTM version 5.) Nothing worked. Even if I tried to sync a folder with one contact, I got the same error, “unable to complete synchronization”. Since I had tried different computers, different software, and different Outlook files and profiles, it became clear that the problem must be with the device. I tried wiping the contacts, and then wiping all data, from the Storm. Still the same error, “unable to complete synchronization”. Finally, after several desperate hours, I downloaded an earlier version of BB OS 5 from the RIM web site and installed it. Since downgrading my BB OS, all my contacts have beeen syncing fine.

Remember that if you have data on your BB that is not in Outlook, you should back up your BB before trying this. Since all my data was in Outlook, I just wiped everything on the device with abandon as many times as I needed to.

Hi Roberta,
I too, have had a rather fruitless internet search on this problem until I came across your post. As I have everything in Outlook on my computer, I don’t have anything I can’t loose on my BlackBerry so I’ll go ahead and try your suggestion. One question though: can you give a little more detail on how to downgrade the BB OS? I’m not really sure how to get an OS onto the BB in the first place, so don’t know if I’d be able to figure out how to get an older version instead of the newer verson.
Thanks for your help!

Hi Anja,
As best I can recall I found the older version on the BlackBerry web site. Try googling the site. If you’re not sure how to change the OS on your phone, it’s probably safest if you have your phone service provider walk you through it, or call in a professional. You don’t want to accidentally delete all your data or turn your phone into a paperweight!

Hi Roberta,
Shucks, but you’re right. My phone right now without any contacts is little better than a glorified paperweight – however a paperweight that does receive calls, so I shouldn’t give up on it yet.
Have a great weekend!
