Ok so you need to be a bit more detailed on exactly what you did. Updating from desktop manager usually goes to the Internet for the files. Sometimes the connection is bad and the data can corrupt the download. Try downloading the files to your pc and do the update locally, not on the internet. Make sure you get the files from your carrier for your phone model or from Blackberry directly. Do not try to load any files not designed for the phone type.
If nothing works you might just have a defective phone and you should bring it back to the place you purchased it. If it is new it should be warranted.
