Hi,
I followed these instructions in order to get Mer (0.17testing10) on my N900.

After some tries I finally partinioned the MicroSD card correctly I also made the .item file in the bootmenu.d directory but when I choose Mer from the bootmenu, the device crashes (turns off) after some seconds.

I'm out of ideas, what can the problem be? Wrong file permissions? I triple checked the lib/firmware binblobs.. Everything seems ok
