Give this phone time Breadbutcher, its really not as complicated as it seems.
As far as media files, its as easy as plugging the phone into your computer and dragging and dropping files onto the phone (hopefully you have a microSD card).

^^ is a little setup guide that was made. Basically, you need Microsoft .net 3.5 installed first (a lot of applications need this). When installing applications, you can save it to your computer, then drag and drop it to your device. On your device, go to file explorer and open the file. It will install the file. Other than that for other tweeks and features, only a few registry edits will be needed and they aren't that hard to follow (you will need to get a registry editor)
Hope this helps
