Under certain circumstances database scan skips existing files and should be blazing fast (as observed on my device). There were several reports of people waiting for minutes on device startup; I believe that the cause is a software malfunction. Therefore I need more information from affected users, which may (or may not) confirm the bug.
Hardware has nothing to do with regions. This is clearly told on pages I linked; if it's not clear, please re-read the pages and ask related questions. You should also continue reading this thread from whatever page you stopped on (was it 480+?).
=========
I've updated wampy and scrobbler installers, installation process should be less confusing now.
There is no need to upgrade, no new functionality at all, just installers.
You can test them if you want and report any issues (or lack of them).
