How to upgrade handheld firmware to the most available recent version

Hi,

 

I have a BB 8800 (T-Mobile) and I tried to update current firmware (4.2.1.101) to the recent OS version. I went to the T-Mobile site and found that there was older version (4.2.1.74) than installed on my handheld.

 

So, I did the following. I checked all carries on this page and found that Orange UK offers handheld version 4.5 for BB8800.

 

I downloaded handheld 4.5 software from Orange UK site. Installed it on my PC.

 

Deleted the VENDOR.XML file located at:
C:\Program Files\Common Files\Research In Motion\AppLoader\VENDOR.XML

 

After that I connected my handheld to the PC and ran Blackberry Desktop Manager.

 

And it upgraded my handheld OS to the 4.5.0.52

Did you delete Vendor.xml file before or after the download?

I deleted Vendor.xml AFTER installation of new handheld OS software on my PC.

 

After that I connected my Blackberry and PC via usb-cable and started Blackberry Desktop Manager software.
