My Device: Curve 9300

Downgrading my 9300 from OS 6 to 5?

How can I downgrade my device from the OS6 to OS5? I've tried to download the device software, but I can't even see the OS5 on the update device menu in my desktop manager. Please help me.

Hi jacv94

 

Welcome to BlackBerry Support Community Forums

 

 

If you want to downgrade your device to OS 5 ,try it manually.You had to download an OS pack from Carrier site ,or try this :

 

1.Download the OS 5 you  from here and Install it in your PC or Laptop Carriers  or  Telefonica

  • (make sure you are downloading for the same model as you have )

 

2. Download and install the latest BlackBerry desktop software from here BlackBerry desktop software

  •     Then if it allow  perform your backup of your device.

   

3.Search your C: drive for Vendor.xml and delete them, there may be one or two vendor.xml ( On your Pc change your folders option to show hidden files/folders ) :

 

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

  

4. Use BBSAK from  http://bbsak.org/   and wipe the device then after you get the error 507 ( no OS ) then proceed to next step.

 

5. Go to C:\Program Files\Common Files\Research In Motion\AppLoader. (For 64-bit Vista or Windows 7, the path       will be C: > Program Files x86 > Common Files > Research In Motion > AppLoader) double click Loader.exe

 

      Upgrade will continue then After Installation of New OS 5 restore your backup from BlackBerry desktop

Software.

Hi jacv94

 

 

                   Please Search the loaction mentioned above from where you had to delete those VENDOR .Xml files ,If your are using Window 7 Go to My Computer > Click Organise > Folder and Search options > On Folder Options Click on View > Make sure " Show Hidden Files ,Drives and Folder " is marked.

 

Once it is done Search your C drive and delete those files then it will work.
