Instructions for loading this OS on ANY carrier's 8100:
Instructions for installing:
(Be sure to check out TMo's installation instructions at the download site.)
1. Make sure you have the latest version of Desktop Manager installed. It's 4.2 SP2.
Download it

(The version listed on the TMo site is quite outdated, I don't recommend using that one.)
2. Download the above file to the PC then install it to the PC by running the file you downloaded.
3. Locate the vendor.xml file and delete it. It's located in c:\program files\common files\research in motion\apploader
4. Plug in BB and Open Desktop Manager. You should be prompted to upgrade.
The process takes about 45 minutes to an hour depending on how much
data you have to backup and restore during the process. Once it's done
loading the new OS it will reboot (it may do this twice during the
entire process.) You will see a white screen with an hourglass for up
to 20 minutes at a time while the DM says "waiting for initialization."
Don't unplug from the PC & Don't remove the battery unless the
spinning hourglass has been there for 30 minutes or more. If the
hourglass has been spinning for more than 30 minutes continuously you
will need to wipe the device with JL_Cmder (close out of Desktop
Manager during this process.) You will then end up with a white screen
with small icons and an error code number like 507 or 543.
If you end up with a white screen with small icons and the number
507/543 (which happens occasionally during an upgrade process,) simply
connect to DM again and run application loader again and it should load
the OS to the device. You will lose your 3rd party apps if this
happens. You can prevent this if you have a current 3rd party app
"backup." Learn how to backup 3rd party apps
