Re: Is it possible to re-install an old BB os
One method to use is finding an autoloader for the OS you want to load.
The autoloader will put in the older OS . The auto upgrade should be disabled to prevent an OTA upgrade. Another issue is the backups made on newer OS will NOT work on the downgraded OS.
Autoloaders were used to allow pc users to directly load software to the Blackberry and not use LINK or other database tools...
do an internet search for the level you want and hopefully one still exists. I saw some at 10.2 level.
Keep in mind the phone will not accept any backups made on later OS. Not good if you have a lot of contacts and other items.
There is a post on autoloaders. J Sanders listed many OS versions.
