I'm not sure if OS5 exists for that model...you will need to dig through the Download Portal to see what is available from all carriers. I rather doubt that OS5 exists for any model that is now on OS7, but you never can be sure without actually doing your own due diligence:
From a PC, you can install any compatible (e.g., for your exact BB Model Number) OS package to a BB via this procedure:
Note that while written for "reload" and the Storm, it can be used to upgrade, downgrade, or reload any BB device model -- it all depends on the OS package you download and install to your PC. 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:
Be sure that you remove, from your PC, any other BB device OS packages as having more than one installed to the PC can cause conflicts with this procedure.
If you are on MAC, you are limited to only your carriers sanctioned OS packages...but can still use any levels that they currently sanction. See this procedure:
Good luck and let us know!

Link doesn't work it says error
Link does not apply to a pre-BB10 device. You need to be using the Desktop Software, not Link.

And could you install os for different models and if no why not?
No. Each OS package is specific to a specific device model number, and they cannot be interchanged. Each specific device functions differently from others (e.g., different screen resolution, different capacities, different radios, etc.), and each OS package is written specifically for a device model number, and cannot be used on others.
