I have received my replacment pearl. I am having trouble finding a way to downgrade my OS from my old pearl. Anyone know where or have the link to 4.2.1.107?
 
Go to Start>Control Panel>Add or Remove Programs. Delete all versions of the OS from there.

Then go to www.tmobile.com/bbupgrade Go there and select the OS for the 8100. Then enter your phone number which will allow you to download and install the OS to your PC (no need to delete the vendor.xml file since it's a T-Mo OS). Connect the BB to the PC and it should do the rest automatically.
 
Try this:


Uninstall the OS and Desktop Manager from your PC via the Control Panel and then go here to reinstall the OS

and here for Desktop Manager

Install Desktop Manager first then the Device OS (delete the vendor.xml file if you install an OS that is NOT from your carrier).

Connect the BB to the PC then open Application Loader. Select Update Software and it should walk you through the rest.
 
I bricked my 8320 once and found some help here in the forums.
I can't remember the steps exactly but its something like this.
Remove the battery, connect the phone to the pc and start the downgrade again as usual. Before the phone reboots replace the battery again.
Hope that helps.
