I'm trying to boot "mer" on microsd following this guide: http://mer-project.blogspot.com/2010...okia-n900.html All this in order to use the dd command (but also to try a different operating system ..).. But I have a problem that afflicts me T_T I partition the SD using gparted, i format it with ext3 file system... Then i use the tar command to put all the necessary on the sd, copy the content of the firmware directory, create a file called mer.item in /etc/bootmenu.d, install Bootmenu for n900 ... Finally i insert the card in the phone, push the power button with the keyboard opened... I select Sd partition... Then appears Booting from mmck ecc ecc.. But nothing happens and the phone turn off ... What's the problem ???
