Re: problem with curve 8520

Hi and Welcome to the Community!

 

In all you provided, I cannot quite tell if you have done EXACTLY this process...the order of this process is critical, as is the success of each step before proceeding to the next step.

1) Make sure you have a current and complete backup of your BB...you can find complete instructions via the link in my auto-sig below.

2) Uninstall, from your PC, any BB OS packages

3) Make sure you have the BB Desktop Software already installed

4) Download and install, to your PC, the BB OS package you desire:

  • http://us.blackberry.com/support/downloads/download_sites.jsp
  • It is sorted first by carrier -- so if all you want are the OS levels your carrier supports, your search will be quick. However, some carriers are much slower than others to release updates. To truly seek out the most up-to-date OS package for your BB, you must dig through and find all carriers that support your specific model BB, and then compare the OS levels that they support.

5) Delete, on your PC, all copies of VENDOR.XML...there will be at least one, and perhaps 2, and they will be located in or similarly to (it changes based on your Windows version) these folders:

  • C:\Program Files (x86)\Common Files\Research In Motion\AppLoader
  • C:\Users\(your Windows UserName)\AppData\Roaming\Research In Motion\BlackBerry\Loader XML

6a) For changing your installed BB OS level (upgrade or downgrade), you can launch the Desktop Software and connect your BB...the software should offer you the OS package you installed to your PC.

6b) Or, for reloading your currently installed BB OS level as well as for changing it, bypass the Desktop Software and use LOADER.EXE directly, by proceeding to step 2 in this process:

If, during the processes of 6a or 6b, your BB presents a "507" error, simply unplug the USB cord from the BB and re-insert it...don't do anything else...this should allow the install to continue.



You may also want to investigate the use of BBSAK (bbsak.org) to perform the wipe it is capable of.

Good luck and let us know!
