Dear all: Does someone know how to boot android when N810 power on?
1. In previous, I power on the N810 (into maemo) and then type chroot XXX in "X Termianl" to start Android. It's ok. 2. I modify the boot menu to make Android file system become the rootfs, and cp /init to /sbin/init ( I'm not sure if necessary). Then, N810 repeat power on/off and no any error message. Could someone give me any hint about this. Thanks.
