How to Install or Upgrade to a New RIM BlackBerry Operating System (OS) with AppLoader's BlackBerry 101 Lecture Series
By Crucial_Xtreme on 17 Apr 2009 10:56 am EDT

Hello Class, today we're going to learn one of the most important procedures concerning your BlackBerry, but also one of the easiest. As CrackBerry Nation knows, RIM is constantly developing and testing new software for all of its devices. So as true CrackBerry addicts, we like to keep up with the latest and greatest. Today's lesson is another step-by-step guide on upgrading your device's Operating System(OS) using the Application Loader method. We already have a BlackBerry 101 that guides you through the upgrade process using RIM's BlackBerry Desktop Manager software, but for many new to BlackBerry owners the AppLoader method is a bit simpler with less chance for error. Let the lesson begin!

Download BlackBerry OS!

First you will need to download the new BlackBerry OS to your computer. You can check for Official Software updates on BlackBerry's Download Site.

Select your provider, fill out the forms and save the file to your computer's desktop. Now as most of CrackBerry Nation knows, there are unofficial versions (betas, leaks) of RIM software floating around the interwebs. If you decide to install one of these versions you do so at your own risk and cannot count on your service provider to help with tech support. Sometimes these versions are full of bugs and other problems so be cautious. Once the file is downloaded double click the icon from the download and select RUN. You can and should always click into the CrackBerry Beta OS and Storm OS forums to do your homework before giving an unofficial release a go.

This process of installing the software to your computer will take a few minutes and you will need to select your preferred language and accept a license agreement. If you're using unofficial software or a software version from a different service provider other than your own, after the installation wizard is done you will need go to the Apploader folder and delete the Vendor.xml file. It can be found following this path:


Vista users is basically the same: C:\ProgramFiles(*86)/CommonFiles\ResearchInMotion\Apploader.

Delete Vendor.xml!

Now it is time to get the actual install process started. After the deletion of the Vendor.xml file (if needed) it's time to plug in your device to the computer via USB cable and then double click on the Loader.exe file.

Running The Application Loader!

The Application Loader Wizard will start up and you will need to select 'Next'.

Application Loader Wizard! 

The next step is to identify which communication port the device is connected to. The Wizard should automatically detect the port and should display USB and your PIN number. Select 'Next'.

Select Communication Port!

Next the Application Loader Wizard will read your devices system configuration. If for some reason you happen to be downgrading a box will pop up and ask if you want to change the systems applications(OS) or leave them. You need to select 'Replace Devices Applications with older version'. If you are not downgrading you will see the Device Application Selection screen. Here you need to make sure applications such as BlackBerry Attachment Service, BlackBerry Messenger, and 3rd Party Application boxes are ticked, and any other applications you want installed to the device and select 'Next'.

Adjust Loadable Files!

Now it is time to make sure the Application Loader Wizard backs up and restores all information on your device. Select 'Automatically Back Up' and make sure you have them emails box checked if you want those restored also. Then select 'Next'.

Back Up Your Data!

Completing the Application Loader Wizard screen will come up next and and show you exactly what Applications are being installed. Make sure everything you want installed is selected and select 'Finish'. 

Completing The Application Loader Wizard!

This process, depending on what model device you have can take anywhere from 20-45 minutes. DO NOT UNPLUG the device from the computer and DO NOT UNPLUG the USB cable from the device. This will cause you to have a bricked device and definitely give you a headache. Just be patient. When the Application Loader Wizard is finished the Wizard will say Loading Operation is Complete. Then you may unplug your device and enjoy the new Operating System.

How to Install or Upgrade to a New RIM BlackBerry Operating System (OS) with AppLoader


I updated my software but now the preloaded pictures are not there. Please HELP! Also, I'm not able to update me "email settings"

Haha I just dove in last night and took the moderators instructions and did this to upgrade from .75 to .122 (wow should have did this a long time ago) sure wish I had these picture instructions as I wasn't 100% sure if I was doing it right or not but turns out its cake and everyone should upgrade if your on .75 and waiting on verizon.

Fabulous write up CX!!!!!! Gonna add it my my recommended noob reading list RIGHT next to your 3rd Party Apps backup thread. :)

I am sooooooooo glad to see these basic instructions. I have been trying to get .122 and was afraid. I can't wait to get home to do this. I will no longer wait on an official OS. For what??? Thanks Crackberry. You rock!!

The path for vista isn't working for me! I tried the xp 1 as well and yet again it sets up disappointment. OMGGGG! Anyone wanna help me?

I've done this my last two upgrades as well as upgraded my friend's Storm and I have to say this works without a hitch! Love it!

I was running .113 and was very happy, but I wanted to try .122. I could not figure it out last night, but thanks I have loaded .122 and so far so good. Thanks again.

Not right how RIM doesn't give two **&^%'s about us MAC users. While I really like my new curve 8900, it may be my first and last blackberry.

I went to the Apple Store over the weekend because I was having connectivity issues with my Storm... Their response to me: "Get an iPhone, problem solved." No one even "tried" to help me. Macs can be great machines, but they sometimes don't function in the "real world." If you you want to be exclusive to your own products only, move to Mars...!!!

has anyone run into the issue where after downloading, it takes me to device application selection, but it only gives me my third party apps, no option for the os that i am installing. I followed everything step by step up until this point. If anyone has any advice, I would love to get this new software on by storm!!!! (the .75 is completely bootleg)

Thank You SOSOSOSOSOSOSOSOSOSO much for the GREAT instructions with screenshots!!! I just installed on my unlocked 9530 and its GREAT!! much better than .75


I just upgraded my BOLD to .247. It went flawlessly. I have to admit to being one of those noobs who were afraid to upgrade the OS...but no longer !!!

I have a Storm 9530 on Verizon and have installed 109, 113 and 132. In each case I have left the previous OS installed on my PC. Is it okay to leave multiple OS installed on my PC or should I delete some or all? I have each OS download saved in a separate directory on the PC.

How do you transfer all of you games, pictures, settings and etc from your 8330 curve when you replace a 2GB mem card with an 8GB card? Tried the DM but couldnt figure out how that worked.

I ran the App Loader LOADER.EXE file that came with the OS I downloaded and it told me the same thing DM told me: That there are no updates for my 8330m to upgrade to, even though it's running .127 OS.

What gives?

How about us LINUX users, at least RIM is coming out with compatibility with Mac (probably a few years too late). Want Linux compatibility, gotta wait till someone with enough knowledge gets sick of not having their blackberry work with their Linux, and hack open the desktop manager and create a working version from that (cause we all know RIM sure as hell won't bother to do it).

hi , i have downloaded and installed on my pc but i am not able to install it to my mobile...everytime i try to do that my bb desktop manager shows me the already indtalld setup of 4. version , i desperately need this guys pls help what should i do...thanks

The v5 loader.exe routine would not see my Storm hanging on the USB - Had to un-install and then re-install my desktop manager [v5]. - Go figure?

I then ran the the loader.exe again and everything was good until it got to the very end... install hung without going to the "restore" function. After an hour I pulled the plug.

Turns out it did a restore of most everything but I still had to go back in and setup a lot of stuff for the GPS and ringtones, etc.

Mostly I would say it was all okay and v5 seems fast and nice.

Thanks for the tutor.

Im a newbie to the blackberry and i've been reading up a lot on this website/forum to absord as much information i can to get to know blackberry device(s). But in all my readings, i've come across a few forum posts regarding deleting the "Vendor.xml" file. Can I ask why you would do this? Because last night I upgraded my OS to the latest RIM release via DM. My device is working just fine as of post time. Is there only certain upgrades you need to delete this particular file?...or is it everytime you upgrade? But most importantly, why should the file be deleted (from the sounds of it before going through the process of upgrading)?

Guys, need some help here please.
Trying to install OS 5 (current on Having read all the help I can get, I have installed latest Device Software Updater (, installed the OS file (have and I made sure I delete the vendor.xml file prior to running the Updater.
I simply can not get Updater to "see" the version 5 files! I uninstalled the whole lot and re-installed it, deleting vendor.xml again. Still no joy. Did a battery pull out of desperation, still it eludes!
What am I doing wrong?
Some pointers will be appreciated at this point.
Thx in advance!!

I have a Bell 9530 and want to upgrade to the MTS released 5.0 OS. When I go through the steps derscribed, the App Loader does not show the OS version on my Berry. I also noticed that it reads the Device Service Record everytime I run Apploader or DM. I did delete the vendor file before I ran the OS program. I found the vendor XML file again after and deleted it for a second time. Is there a way to install this OS on the 9530? Thanks for your help on this! BTW I am on BES.

Try searching your computer for another vendor.xml file and if you find one, delete it. I am using Windows 7 x64 and had the same problem. I did a search of my C: drive and found a second vendor.xml file in a sub-folder of my user folder. I deleted it as well and then the upgrade worked no problem.

C'ant thank you enough.. just installed from verizon on my telus storm...easy as cake.

thanks again,

people like you make the tech world a better place.

So...I am a 'computard' Computers (well technology in general) and I do not get along. These instructions were absolutely perfect! I was able to install the newest version of os (not offered by my carrier) because of them...MANY THANKS!!!

I've tried upgrading my os numerous times and can't figure it out =[ I've read this over and over and deleted the vendor file. oh well

I have worked for three days to get my tour os upgrade. Finally I found one that worked!! Your pictured helped so much!!

I am using a BB storm on att prepaid with out BIS and everytime i try to update my phone it says BIS is required is there any way to get around this. Thanks for the Replay

I've deleted the vendor.xml file but when i run the loader it doesn't give me any options to install the 5.0 os. All i can do is delete or add apps but there is nothing about the os. after going through the whole installation process it said "Update was succesfully done", but when turning on the blackberry the os was still 4.6. does anyone know what to do?

Just did the upgrade. Everything went fine........except: Visual Voice Mail is nonexistent. Any idea how to fix?

Thanks in advance.

is it normal to take an hour to try and connect to the device? i gave up and unplugged while trying to downgrade, phone works fine.

I am having the same problem as many users. I followed instructions but it wont give me an option to upgrade my OS only the option to delete or keep applications. however the os stays the same. I have an unlocked storm with os. I have desktop software 6 if that makes a difference. Mine is running on ATT currently. Please help, I am not sure what to do next and i didn't notice any reply to the other users with the same problem as me. It keeps saying:

This BlackBerry® Device Software upgrade includes new features and significant enhancements to the BlackBerry® solution and, as such, is only available to users with an active BlackBerry subscription. To learn more about BlackBerry® service, please visit

will this work to upgrade my bold 9650 software to OS6? I have OS 6 on it already but if i didnt need to download the leak and could of just done it through downloading the latest DM 6.0 and walking through the same steps you did. could i just downgrade my software on my bold to 5.0 again then just upgrade it through apploader to 6.0 since i have the DM 6.0? If you know this will work or any other way i could of done os 6.0 on my 9650 let me know, please :)

i just upgraded my own BB Curve9300 with OS 6.418. it is an amazing OS with new themes & faster.....
thanks a lot for your guidance and support

That was an excellent post if I were using a PC but I've changed to a MAC last year and I'm not as familiar with finding such files as the vendor.xml file. Does anyone know hoe yo install the Sprint OS6 upgrade to a VZW 9650 using a MAC? Any help will be GLADLY taken...

I like many others am having the problem that the OS will not update. there is no option to check that allows me to go from to

I've followed the steps exactly (three times) and in each case, no phone OS update

I have an unbranded 9700 running OS5.

I downloaded the OS6 file from the Blackberry site for my carrier (Rogers) and deleted the vendor.xml file...However, when I run the loader, there's no option to install the new OS.

I can't get it to work.. i'm upgrading my 8520 from 4.6 to and when it has read the system configuration all that shows up are the apps i got on my BB and when i click next it says that no actions are required. how can i get it to work? please help :)

i MUST be computerally retarded. i've tried this a bunch with the os 7.1 and nothing. deleting the os software right now to try again...xp is not liking me apparently

HELP!!! I still cannot update my os from v4.6 to v5.0..the part where the Device Application Selection my Blackberry Core Application did not came out from the selection. :(

i'm having problem here. after i upgrade from OS 7.0 to 7.1, my 9900 still remain in 7.0. is that my country didn't support for the upgrade of error there?

Here is where I found the second vendor.xml file: C:\Users\Owner\AppData\Roaming\Research In Motion\BlackBerry\Loader XML

After I deleted it, everything worked fine.

Mine isn't working it says:
"The Blackberry Desktop Software does not have Blackberry device software for the device that you have connected to your computer. Contact your wireless service or system administrator.
