How to re install older version device OS

Hi,

I am user of BB 9800 in India. Few months ago I upgraded the BB OS to 6.0.0.749, Rel 3159.

But now I feel the older version 6.0.0.747,Rel 3155 was better performing for me. I have both these OS downloaded in my laptop. How can I install the older version of the BB OS?.

 

Thanks in Advance,

Regards,

B.D.Badan

Hello balubadan

 

 

There are many methods available , Or try this :

 

1.Locate your Carrier Or Download the OS you desire from here  BlackBerry Software Download Site

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

2. Now Double Click  on the file that you Downloaded to Install it on your PC

 

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

  • Then using desktop software perform your full backup of your device.

4.Search your C: Drive for any Vendor.xml files 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

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 restore your backup using BlackBerry desktop

Software.
