michaaa62 thanks for all the help anyways but now unfortunately my N900 didn't boot up no matter how turned on the device because i uninstall it's kernel. The reason i did this was to restore it's original nokia kernel because overclocking my device was one of the main reason why the memory was corrupted so i reinstalled it but accidentally my n900 automatically shuts down w/o having to reinstall the kernel. This is my second attempt to reinstall it following the steps here http://wiki.maemo.org/Kernel_Power but when im in the step # 6 it shuts down automatically and then my phone didn't boot already. My fault also because i tried to do it w/o a net connection but due to the corruption of my memory i can't access to the net and also i tried to do it w/o a net connection it is possible..Am i correct right?? What should i do about this?
