    I recently tried upgrading something on app world and it got stuck so I rebooted my phone and it got stuck about 80% on the boot screen. then I tried connecting it to BBSAK and DM. It never worked. then now it is stuck on the error 507 screen so I can connect it . Although the DM asks to retry or update. I downloaded the OS 7.1 for my bb 9900 from a provider in my country. And I installed it on my PC but when I run it on BBSAK to install after the apploader runs it says

    "the blackberry desktop software does not have blackberry device software for the device that you have connected to the computer"

    What do I do!?

    You need to delete BOTH the vendor.xml files from your computer. Search the whole computer. Be sure you are viewing all the files and folders including the HIDDEN ones.

    32bit Windows XP, Vista, 7, 8 - C:\Program Files\Common Files\Research in Motion\AppLoader

    Scroll to the bottom, delete Vendor.xml

    Go to C:\Users\*User*\AppData\Local\Research In Motion and delete the other

    I deleted the second one because the first one was not there. So It seems both are not there anymore.
    So now it still gives me that error?

    Try a PC reboot, those are fun. Sometimes they jog things too.

    Just tried the other option that was not recommended and it went through. I chose the apps to install. But then when It goes onto the next installing screen the phone restarts and the installing thing says device unplugged and keeps on rebooting.
    Is it supposed to
