It'd be best if you read through the thread and then asked questions afterwards if there is something that isn't spelled out somewhere throughout the thread. They aren't THAT long and you could learn a lot. This stuff is not rocket science, but it does need patience and reading comprehension. The threads there are populated by n00bs and advanced users as well, so there's a good chance someone has had the same questions as you do. The people on those threads will also probably be more likely to help as it's not a very popular phone and not much support for. xda doesn't even have a specific forum for it. But, as you start, you'll need a working Windows (XP/Vista/7/8/8.1) computer or Linux, if you're more comfortable with that for some reason. A good data sync cord. The correct drivers. You probably only need the system.img, but won't hurt to do the others to get a complete full restore.
