However, the boot option is not coming up and it directly boots to Maemo..
Slide the scrren out and the reboot. press the which ever option says nitdroid. Wait for reboot now you can slide it closed and prepare for the 1st initial setup.
Also when you want to go back to Maemo you have to reboot and slide the screen up again. basicallly the phone will remember what it booted the last time when the keyboard isn't out and when it is it activates the Multiboot Boot menu.
If i use nitroid uninstaller, because i had nitroid 4 months ago, will it install nokia original kernel ? It says: will revert to original kernel and im currently using kernel power 48
