    Just use the Add/remove programs feature of your PC to delete 4.5, then D/L and install 4.2 back on, and you'll be all set to downgrade.

    Did you install and test your carriers OS before you installed v4.5?

    If you did, no problems with the roll back. If you have not, you will need to locate, download and install the correct software.

    Sorry if I was not clear.

    Before you installed the beta version v4.5, you might have, previously, installed the original v4.2.2.180.

    That is what you need to roll back. You can download it from T-Mobile's link to BlackBerry.

    i did a search for tmobile v4.2.2.180 and click the link. you will go thru tmobile to download the os. once you do that it will have a pdf to walk you thru it. if have the os installed on your compert just open the desktop manager and add application from the desktop manager and you see the old OS and intall. it will take about 30-50 minutes for install. it has been working like a charm. i will hold of until the final version os 4.5 is released by tmo. i hope this answered question
