I recently went back to a 7250 on Verizon.
I purchased the phone from Ebay, it is activated and working perfectly.
I believe it is software version 4.1.268
There are newer version I would like to upgrade to that are available via the blackberry web site.
I have been unsuccessful trying to do this on windows (7) and (10) pro.
Has anyone tried to do something similar?
Any suggestions?

Thank You.
