[Q] HTC One M8 RUU topic

So I converted my phone to a GPE edition. Now I'm thinking of switching back in the near future to check out what HTC has done with Android 5.0.x but is there an RUU file out? Cause on the HTC dev site there are a lot of FW files but I'm not sure if they are the correct one. Also my phone was unlocked I live in Belgium so wich one should I use?

Thanks in advanced!
