I've just got an N9 few days ago. And I really want to flash it into Meego&Sailfish&Andriod(probably nitdroid?) multiboot. But many sites are down now, and since I'm in China, it's almost impossible for me to access sites such as archive.org for backups. So could anyone help?

And I really need a guide to teach me how to use ubiboot. I have a little experience in Linux but I'm new in N9.

BTW, I used N9QTweak and my N9 can't automatically lock it's screen. And if I lock the screen manually, it will just keep showing the clock and won't lock, even if I block the proximity sensor.
