oldest of the old versions..HELP!

i kinda need some help here .. my friend has got the oldest of the old versions of blackberry on her curve 8520 .. and here i come , the most helpful friend ever , decided to borrow her smartphone and volunteered to update the software so that she won't have to suffer .. unfortunately , upon making thousands of attempts updating it , it seems that i really cant figure out how to solve this problem that i encountered .. so i need your help !



"This BlackBerry Device Software upgrade includes new features and significant enhancements to the BlackBerry solution and, as such, is only available to users with an active BlackBerry subscription.To learn more about BlackBerry service, please visit www.blackberry.com/service"



* i dont know what the hell "active BlackBerry subsciption" means .. does it mean i have to be subscribed to email notifications? or be subscribed to an active BBM or something?

* i have updated my own blackberry software few months ago and i didnt experience this kind of error at that time ..





any kind of help will be much appreciated ..

Re: oldest of the old versions..HELP!

Hi and Welcome to the Community!


Indeed, some of the newer OS levels indeed require subscription to, from the mobile service provider, a data plan that is adequate to enable some BB-specific services...if that is not in place, then the newer OS is not available to the device -- by default, that is...there is a trick...

The simplest way is to, on a PC (you cannot do this on MAC):

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

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

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

4) If that OS package is from a carrier other than the carrier for which your BB was originally manufactured, then 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

5) Launch the Desktop Software just once but do not connect the BB. Just launch it and then shut it down.


6) Now, disconnect the PC from the Internet.


7) Launch the Desktop Software and connect your BB...the software should offer you the OS package you installed to your PC. If, during the process, 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.


8) After it's all done, then reconnect the PC to the Internet.


It's that bit about being connected to the Internet that is the problem...the Desktop Software is checking to see if the BB is associated to an adequate data plan from a carrier...if not, then it refuses to allow the use of the newer OS. Disconnecting the PC from the Internet "Fools" the Desktop Software and allows the install to proceed.


Oh -- and don't forget to backup.

Good luck and let us know!
