The BlackBerry OS v18.104.22.1680 was made by BlackBerry (RIM) and released by Sprint, but it will run on any 9650. Often, just wiping and loading the phone with the original software fixes a lot of problems.

Many of the OS files are interchangeable from one BlackBerry to the next, and the goal is to make a combination of files that work well together. The goal might be to make the OS run a little smoother, to make the battery life a bit better, or to make the browser work faster. Often, however, a hybrid will fix a particular issue at the expense of creating another.
Your original post is lacking detail. Did you just buy the phone? Was it working at one time, and recently stopped working? Where are you trying to use it (what part of the country)? You did not describe any of your "many issues", so nobody here will be able to help you further without more information. There are many folks here that will help however they can. The more info you deliver, the more help you're likely to get.
