Re: How to downgrade blackberry bold 9700 from os 6.0 to os 5.0?

Mac users are not able to manually upgrade/downgrade the os on their phone.

 

But you can try the following way:

 

Connect your phone to your computer and start the Desktop Manager.

 

Click on Update or check for updates. It wil check and tell you no updates are available. You might also get the option to view other versions and you may find OS5 versions in the list with Downgrade besides them. Select the OS5 which is on the top of the list as it is the latest OS5 version available to you. Your phone will be downgraded to OS5.

 

Hope this helps. Please let me now as to how it goes.

Re: How to downgrade blackberry bold 9700 from os 6.0 to os 5.0?

I have a bold 9650 and did a wireless update to OS 6 on my phone and I really don't like it. I read your instructions and downgraded to OS 5 on my PC but I'm kinda confused on how to sync my phone and my PC so that OS 5 is on my phone again. Can you help?

Re: How to downgrade blackberry bold 9700 from os 6.0 to os 5.0?

I did read that part however I never had OS 6 on my PC only on my phone, so I can't find the files you mention to uninstall/ install. What should I do if I have OS 5 on my PC and OS 6 on my phone? Thanks

Re: How to downgrade blackberry bold 9700 from os 6.0 to os 5.0?

Uninstall OS5 from your computer (it should be listed in the add/remove programs).

 

Go to the Downloads site, and download OS6. Then, install it on your computer. Now you have OS 6 on your computer.

 

One note, I am not talking about the version of Desktop Manager, I am talking about the actual OS for your device.

What happens when you try to save your documents? Have you gone t6o the DataViz website and checked for an update to the "Office" to Go applications? There is a newer version (free) than the one that came on my phone.

 

Yes, you can go back to OS 5. Whether or not you get everything back depends on the quality of your backup.

Re: How to downgrade blackberry bold 9700 from os 6.0 to os 5.0?

Hi. I did my upgrade to OS 6 on my 9300 using a PC at work. I no longer have access to that PC but I want to downgrade using another. Please how can I do it, considering there's no OS 6 to uninstall on the PC? Thanks

Couple of questions. When you say "use the control panel to remove the OS"...I'm not clear on which things I need to remove. I have these Blackberry-oriented applications listed:

 

  • Blackberry Desktop Software 6.1
  • Blackbery Device Updater
  • Blackbery Device Software v6.0.0 for the Blackberry 9700.

I take it I just need to remove the last one, right? Or do I need to remove other stuff too?

 

Also, am I better of doing it this way (as you described in post #2 on this thread) or am I better off using Desktop Manager, choosing Device | Update | View Ohter Versions and then selecting one of the 5.0 versions listed? I'm also not sure of what's listed here. For example, I have "5.0 Bundle 1209 (Version 5.0.0.714  platform 5.1.0.146) (downgrade)" and two other apparent downgrade versions of 5.0. I'm not clear on whether these are complete versions of the OS and all apps or just partial "updates"...

Okay, wound up using method #2, just restoring the last copy of 5.0 I had in my "Update" (downgrade) list in the Blackberry Desktiop Manager.
