icon to appear on some carriers. However, unfortunately, some carriers
disable the web browser in BlackBerryOS. These carriers include Nextel,
Telus, and Verizon. Cingular is now enabling the BlackBerry browser if
you call and ask for it to be enabled (To save time on the same phone
call to Cingular, you should also request the Wireless Internet Express
added, as well as Wireless Internet Express Data Connect to add both
the "wap.cingular" and "isp.cingular" Access Point Names to your
account). You may want to wait a few months to see if Nextel, Telus and
Verizon they will enable the web browser. You may want to try calling
them and asking for it. Or you can download and install an alternate
web browser such as Reqwireless if your carrier supports Internet
connectivity on BlackBerry.
I Installed 4.x OS from another carrier. It doesn't work!
This is because you will need to delete or rename the VENDOR.XML file located at:
C:\Program Files\Common Files\Research In Motion\AppLoader\VENDOR.XML
First, install BlackBerry OS 4.x but do not run BlackBerry Desktop.
Next, delete or rename the VENDOR.XML. Finally, run desktop manager to
Help! My Older BlackBerry Is Running Too Slow With 4.x!
If you upgrade an older BlackBerry to OS 4.x, then BlackBerryOS 4.x can
be slightly slower than older releases. A fraction of a second lag, for
example, is normal. However, it should not be so abnormally slow as to
take 15 seconds to launch "Calculator", or that an hourglass shows up
for 10 seconds when you try to view an email message. BlackBerryOS
should NEVER feel 10 times as slow, and if that happens, there's
However, if this happens, you need to free up memory on your
BlackBerry. This can be done by removing unnecessary applications. You
can even uninstall BrickBreaker now if you need to do that! You should
delete all your old emails using "Delete Prior".
Model 7750's are very prone to the "frequent hourglass" problem. If you
have a 7750, it is strongly recommended to upgrade to a newer model
such as 7130 or 7250. One important thing to keep in mind about those
slow 7750's, is you must make sure you're not already too low in memory
before installing BlackBerryOS. Make sure you remove unneeded
applications and delete old emails ("Delete Prior"). Since the
hourglass can suddenly show up excessively on a 7750 when it runs out
of memory (which happens much more often on 7750's than other models of
BlackBerries). Once you free up the memory of your BlackBerry, reboot
your BlackBerry by removing and reinserting the battery.
What If I Want To Downgrade?
Forum member 'bfrye' made a good guide: Here is a quick install guide
to your blackberry. This should easily cover reinstallation of OS and
reverting back to previous OS version as well.
Now if you wish to downgrade your device to a previous version, many of the above steps will apply.
- Download the version of OS you want to install from your carrier's website.
- Extract or install the files from the previous step. They will
automatically install into the correct location. This location will be
C:\Program Files\Common Files\Research in Motion\Shared\Loader Files.
Under this directory you will see directories with the model number of
your device (if you installed the correct files) followed by a version
number. Under these directories will be a host of .alx and .cod files.
Do not modify or delete these files. They are needed to install the new
- Assume the BlackBerry Handheld Manager is installed, when you plug
your device in, a popup will appear and ask if you want to upgrade your
device. Choose upgrade and follow the steps given by the Application
Loader. If you have any 3rd party applications you would like to keep,
locate and select them at this time to avoid having to reload them
after the new OS is installed.
- This will also be the time the apploader will ask if you want to
erase all data and reload or backup and restore the data on your
device. Choose your preference and continue.
- Typically a complete OS reload with backup and restore can take
anywhere from 5-15 minutes depending on the amount of data on your
device to restore.
- The apploader will inform you when the process is complete. After
this, the device will automatically reset itself (sometime this will
take longer than a normal reboot) and once completed and on, your
device will be upgraded and ready to go.
First, you will have to remove the newer OS from your PC. Do this by
going to add/remove programs in the control panel and removing the
software for the new BB OS. Make sure desktop manager is not running
when you do this. After complete, restart the Desktop Manager.
When you plug in your device, if everything went well, the Desktop
Manager should tell you that your PC has an older version of desktop
tools than is installed on the device. It will give you an option to
keep the version on your BlackBerry or downgrade to the version on your
PC. You will want to select downgrade and let apploader do the work.
Should this method fail, you will have to download the file
javaloader.exe from the internet. Place it in a common directory (I
usually put mine in the Loader Files directory for easy access. From
the directory you have javaloader.exe installed in type "javaloader
-usb wipe". This will completely erase all data and applications from
your devie. Now navigate to C:\Program Files\Common Files\Research in
Motion\AppLoader and delete the file vendor.xml. Now plug in your
device and install the new OS from scratch. Open apploader and select
the USB port as your connection. It will then bring to you to the main
apploader screen and all the OS packages will be listed with status as
If you have question beyond the scope of this document please feel free
to post them. However I suggest reading and rereading these steps to
ensure you have tried the most basic and tried steps to load or reload
your OS. Have fun and enjoy!
