How To Downgrade Your BlackBerry's Operating System Posted in BlackBerry 101 on 14 Apr 2009 17:13 by Duvi |

Class is in session... Today's lesson will be on how to downgrade the OS (operating system...aka firmware aka device software) on your BlackBerry. Some of you may have chosen to upgrade to 5.0 or some other OS that isn't just right for you. Luckily, BlackBerry smartphones are one of the easiest (in my opinion) to downgrade. I chose to upgrade to 5.0 on my Curve 8900 (using Desktop Manager 4.6) and I want to go back down to 4.6.1.168 (my favorite).
How to Downgrade Your BlackBerry's Operating System To start downgrading your operating system you'll need your BlackBerry, windows based (sorry mac users; get Bootcamp), and a USB cable to complete the downgrade process. What I'm starting with... 5.0.0.90
Step 1 - Uninstall/Install the BlackBerry OS Software The first step is to delete/uninstall all the versions that you don't want (or at least any version later than the one you are trying to downgrade to). Since I want to downgrade to 4.6.1.168, I would need to uninstall all the versions that came after. In my case that is: .199 and .206. To do this, go to your start menu and then go to your control panel. Then find "Uninstall Program" (I'm using Vista, for XP it is "Add or Remove Programs"). Here, you will highlight the OS and then click uninstall. I usually go by the date the OS was installed to know which OS I need to delete, but if you aren't sure which is which, delete all of them and reinstall your preferred OS.
I have the Storm, Bold and 8900 and still find 4.6 to be the best. I haven't tried and tested 5.0 yet, but that's still in beta at the time of this posting. If you have higher, that should be fine; anything lower, we suggest to upgrade. The latest software can be found on RIM's site located here.
Step 3 - Backup your data/3rd party apps and then wipe device The next thing you will want to do is back up your data and also 3rd party apps (if you wish to or haven't already done so). At this point, I normally use JL_CMDER to wipe my device. I think this is the best way to wipe your device clear of any remains from the OS you're downgrading from. Now you will see a white screen with a '507 Error.' This is what we're looking for, don't worry. You are now ready to install the OS.
Now it's time to start up the Desktop Manager. Select Application Loader and then select 'Add/Remove Program.' You need to select all the applications you'd like installed (Blackberry Messenger, Blackberry Attachment Service, etc.).
After that hit Next. On this screen you will get a confirmation of the software/applications being installed. Click next and watch it load the OS.
Step 5 -Restore your data from backup (if needed) After your OS has been loaded, you can now restore your 3rd party apps and back up file. When this process is complete, you're done! You've just downgraded your OS. Give yourself a pat on the back. Keep in mind that RIM and Carriers will only provide technical support for official software releases. So if you want to play around with some of the betas that pop up in the willd, if things go awry the CrackBerry forums are your source for support - if you call into your carrier for help and you're running a beta, they'll know it right away and ask you to downgrade to a supported release, which hopefully now thanks to this tutorial you can easily do on your own!  The final product - a slightly lower but more stable OS!
Notes - If you use any BlackBerry Internet Service (BIS) accounts, you likely want to resend your e-mail service books even if you're device was automatically reregistered. This ensures that you're taking advantage of any related tweaks that may have been included in the software update. - Immediately following your downgrade, you'll be prompted to log back into a number of applications but some you'll need to manually open to enter your account information. If you have a media card installed, you'll also be asked whether or not you want to turn your BlackBerry's mass storage mode on, regardless of your previous settings. You'll also be asked if you want to run through the BlackBerry Setup Wizard.

Can you guys put up a note that lil old SaskTel has released the 4.5 OS for the 8830, 8330, and 8130?
They were previously running 4.2, 4.3, 4.3.
Isn't this sort of like the thread I posted MONTHS ago... "Proper Upgrade / DOWNGRADE Procedure"
Just wondering...
a bit noob friendly. ;)
**shrugs head**
Understandable. This is nice and purdy with pics and such. And my guide is probably a little outta the loop since OS 5.0 and the likes are making their way out now.
Did not mean to step on your toes Duvi!
Last week when we did our Call for BlackBerry 101 posts this was one of the most popular requests. Much thanks to duvi for covering it in the blogs. And much thanks to you bmc for covering it in the forums. Got tackle the 101s from both sides for max visibility and ease of use.
While i think Duvi did an excellent job, this sort of post can be easily searchable.
I dont see why the need for it to be posted on the front of CB when it is stickied in like every forum, most forums i visit for that matter.
Id rather see a new Verizon Official OS on the front page than how to downgrade...anyone who knows how to upgrade should be equally aware how to downgrade, if not, then they shouldnt be tinkering with their phone(s). Not tryin to be cold hearted and not support the noobs, but this is just ridiculous...
Maybe we should put a banner on top of CB that says "CAUTION: READING REQUIRED!". This might let the illterate know that they will have to read the site, oh wait, they cant read! Forgot! :)
Just my little thought on all of it, take it as you wish!

if you know what to search for. Some users don't. And some don't know what to type in the search for. It's happened to me where I know what I want to find, but the wording is different and does not yield the correct results.
You also have to realize that some users may not even use the forums. All they would have to do is click the "Blackberry Help" drop down above and then click "Blackberry 101 Lecture Series"
You are pretty much a fag aren't you. Don't you have anything better to do with your time. I am reading your response wondering to myself why I am reading your response.
personally, i can say i needed that. thank you very much!
Is this just something your using as example, or was .168 actually a better version for you?
It definitely is my favorite OS. I've never had any issues with it. Not saying 5.0 is bad, haven't kept it long enough; just felt why mess with perfection.
CAN SOMEONE DO A HOW TO GET YOUR CARRIER TO UPDATE THE OS.FU_K A DOWN GRADE MY STORM NEEDS HELP.
Exactly what we need here.
Not to be a terrible person, but I miss the days of blackberry owners being professionals, and not kids who can't figure out the caps lock key.
Did you mean like this?
so you were a professional expert blackberry know it all king of all kings whiz the very second a blackberry entered your hands the first time? just wondering. everybody starts off not knowing much about a blackberry cept what they read before getting one.

does anyone have a link to the official OS 4.6.1.168 for the Bold? thanks

Simple, straightforward and to the point. Good job.
Has anyone run into a runtime error when trying to delete a software file? I am trying to downgrade from .114 but when I try to delete the program from my computer I keep getting an error 2378 message. Any suggestions?
Try this:
Symptoms
When installing or uninstalling the following error message is displayed:
Error 2738. Could not access VBScript run time for custom action.
Cause
This error message indicates that the VBScript engine is not currently registered on the machine where the install/uninstall is taking place.
Resolution
The VBScript engine can be quickly registered by following these steps:
1. Run Command Prompt as administrator
1.1 Start Menu -> All Programs -> Accessories
1.2 Right click on Command Prompt and select Run as administrator
2. cd %windir%\system32
3. regsvr32 vbscript.dll
It worked for me.....
What do I do if when I try to uninstall the current version of the device software, I get the following error:
Error 2738. Could not access VBScript run time for custom action.
Any help would be greatly appreciated!!

Hi I recently upgraded to OS 5.0.0.100 and now wish to downgrade as I cannot get BIS to function for some or other reason. I have followed all of the above steps but I do not get the option to install the system software. I am using BBDM 4.6.
Desktop Manager only shows the applications that I have installed and not any system software eg. OS 4.6. Are there any solutions to my problem.
Thanks
