To make things clear i'll go step by step. I first downloaded the prebuild file ( zImage-power48-ubootMod.7z) sent to me by fabry and saved it in the /boot/Multiboot and renamed it to "vmlinuz-2.6.28.10-power48) then i restarted the system back in Maemo Original Kernel.
Again Restarted and this time booted in "Maemo kernel-power 2.6.28.10-power48" then again restarted the phone and just kept the Key board open but the timer never timed out and phone turns off on timer reaching 7.
