here's the link to the latest official OS and installation instructions to follow: http://www.blackberryforums.com/gene...ilanguage.html
And Since you are unable to boot the phone, after you have installed the apploader, run apploader.exe, then move to the screen where it displays the Blackberry's PIN. Now connect the blackberry to the pc, whilst connected remove the battery and push it back in. in apploader the PIN should read "unknown", once you see that, click next and proceed with installation.
