Re: need Whatsapp on BB 8120 wit OS

Hi and Welcome to the Community!


App compatibility is a matter of both specific device model number as well as major OS level...each developer must port their app to all combinations thereof if they are to support everything possible. Most developers choose not to do that and only support a subset. If the app you desire requires a specific minimum OS level on your specific device model, then you can't use the app until you can be running a compatible version. Please check the app compatibility requirements carefully to ensure that both your specific BB model number is supported as well as to discover the OS level that is required.


But, as you discovered, there is less flexibility when doing OS loading via MAC...with MAC, you are restricted to only your carriers sanctioned OS packages...but can still use any levels that they currently sanction. See this procedure:

  • KB19915How to perform a clean reload of BlackBerry smartphone application software using BlackBerry Desktop Software

The OS download files are useless to you on MAC, and you cannot use an OS that a different carrier may have released. All of those tricks require PC...not MAC. So, on MAC, you can only use what it tells you. If that's not adequate to enable compatibility with the app, then you will have to abandon the use of MAC for your device OS updating and instead gain access to a PC in order to do what is needed.


Good luck and let us know!
