Greetings Folks,
Seems like each day brings more and more threads requesting info on how to downgrade from the latest leaked/beta OS back to an official release. Given this, I thought I would make myself useful and do a step-by-step guide.
BEFORE YOU GET STARTED...
1. If you are new to BB, you prolly should avoid playing around with your BB's OS and just wait out the official releases.
2. In order to upgrade/downgrade OS, you really do need to know a bit about your device AND your computer. If you do not, please save yourself the hassle and stay away from trying OS updates and, prolly, inevitable downgrades.
3. Stay calm and take deep breaths into your belly! This will keep a good flow of oxygen in your brain to help you most likely avoid panic if you mess up.
4. And most important, I do not recommend OS upgrades/downgrades to anyone, especially new folks, and I certainly do not take any responsibility for bricked or other malfunctioning phones.
That being said... here goes-
STEP ONE:
Back it up. Go to Desktop Manager (hereafter referred to as DM) and back up your device.
Here's a link to guide you thru backing up third party apps http://forums.crackberry.com/f3/upda...updated-53201/
Before we get to step two, if you have run into problems in step one, STOP IMMEDIATELY! If you encountered any trouble in figuring out how to backup your device and/or third party apps, you really, really, shouldn't be trying this or any other upgrade for that matter. Seriously, not trying to be snotty, just trying to save you the hassle.
STEP TWO:
Uninstall the OS that you are trying to downgrade from, from your computer.
If you are running XP go to control panel > add/remove programs. If you are running vista go to control panel > programs and features.
See yellow highlight in pic below. Be sure that you are choosing DEVICE SOFTWARE, not the DESKTOP MANAGER.
Once the uninstall has finished, restart your computer.
STEP THREE:
Now that your computer is OS free, download the official version that you would like to install. I'm guessing folks are going for the latest .75 version. You can download it here BlackBerry® Software Updates
Once the OS has downloaded, run the install by following the onscreen instructions.
STEP FOUR:
Plug your storm in and open DM.
Click on Application Loader
Hit start
Once you do, the below screen should pop up. Check the desired OS and hit next.
Now, if you did not do a JL_Comdr wipe (and I DO NOT recommend that you do) you will get this screen telling you that you have a newer version of the OS than the one you want to install. DO NOT PANIC! See the highlight that says hit options to continue.
After you hit Options, you will get this screen:
Choose yes and follow the onscreen instructions to finish up the install. You will be asked to choose applications, etc..., please choose and then hit next to complete.
This process can take some time, so please be patient!
ALTERNATE STEP FOUR:
If for some bizarre reason, you are unable to get DM to work for you, can load the new/old OS directly from the loader.exe file. See pic below
Navigate to this window (address on top of pic) and double click the highlighted file.
Follow the onscreen instructions. You will be asked before the install begins whether you really want to install an older version. Choose to go ahead and install the older version.
Once you have finished your install, do a battery pull for good measure. Once your phone reboots, go to options > about > check the third line down for OS version. Should read 4.7.0.75 if you proceeded correctly.
Good luck folks! And I hope this was useful!
EDIT: For some reason my pix didnt come thru. See attachments below. The pix are in order according to the steps above.Last edited by Rooster; 01-05-09 at 03:48 PM.

This is a well written guide and I am glad that Rooster did not chicken out (sorry, couldn't resist
) from writing it.01-05-09 04:29 PM - Dude! Too funny!If you are doing OTI (Over The Internet) upgrades then it probably is not necessary to uninstall other OSs lying around on your PC.
