Trouble installing a new OS on BB Pearl 8100

Question

Hi there -
I have a BB Pearl 8100. It is unlocked, but loaded with T-Mobile OS (according to Options/About it's: v4.2.0.64, platform 2.2.0.37).
I am using with an ATT/Cingular SIM card for phone calls - for the most part this is successful but occassionally I will get a rash of "call failed" errors upon trying to make calls. Often turning the phone on and off will solve but not a permanent solution.
So I'm trying to load the appropriate AT&T OS on the device. I am following all instructions that I have seen posted on many different sites, including Blackberry.
In short, I am:
1) Downloading and Installing the right ATT OS for a Pearl 8100 from the BB website.
2) Open BB Desktop Manager
3) Connect BB Pearl to computer (via USB).
All of this seems to be working as designed.
However - the directions say that DTM should either prompt me to "Update Now" (assuming the Application Updates Available window appears) - or I should open Application Loader and launch the wizard process. I have to do the latter because it does not prompt me for auto Updating.
Once I do the latter, it does not detect that I have the newly installed OS waiting to be installed onto the BB Pearl. It detects a few applications that are already installed on the Pearl, but no new OS.
I'm very confused!!
I have tried this process with Desktop Manager 4.6 and 4.2 with SP, thinking maybe it had something to do with version of Desktop Manager, but same results.
What am I missing????
Thanks
Brad

Hello,
You can use any OS package on your BB as long as it is one that is exactly for your model number BB. This process is the best I know for installing (upgrade, downgrade, reload) an OS onto a BB:

If you choose an OS package from a carrier that is different from your BB's original carrier, then insert, between steps 1 and 2, the deletion, on your PC, of a file named VENDOR.XML.
Good luck!
