Again, I reiterate to people posting asking help like above, you're much more likely to get help with an app by finding that apps announce thread and posting your question there. Use the Power Search option to look up the thread using the app name and the word "announce". Most often that will turn up the discussion thread you're looking for.
This thread is not a generic help thread to ask questions on. If you ask questions about other things here, you probably won't get an answer (like those above...)
While that may be a quick-fix or a solution that's inevitable sometimes, I really prefer to NOT suggest that as the first course of action. By simply re-flashing, you learn nothing and wind up repeating the same mistakes. Eventually you just get frustrated with having to reflash all the time and look for an "easier" gadget.
That type of "if it stops working, get a new one" attitude is what's lead to the iPhonization of the culture (especially in the US). Much better to at least try to learn what's going on than just start from scratch ever time something goes slightly awry.
Hi, just got a new n900 as my old one the micro USB port broke.. Anyways went onto the application manager enabled all the repositories and downloaded Linux kernel power user... Turned my phone off, the phone vibrates and the Nokia logo appears, and just keeps looping... Screen will go blank, vibrate, Nokia sign, and so on... What can I do to fix this or will I have to flash my device?
