I need some help here, I turned my N900 off just now trying to boot NITDroid, when the multi boot menu shows up, I pressed 2 on the keyboard to boot NITDroid, after a while the phone just turned off, now when I tried to turn it on, the phone just shows the NOKIA logo and turn off by itself.
this was discussed here, use search, anyway : https://wiki.maemo.org/Updating_the_...ng_the_Flasher try reflashing kernel and then try again... (but check out other threads using search, you might find better answers)
make sure that your battery is fully charge 100%.you wont go in to mode if its not fully charge.
take off the back, take the battery put the battery in press u on the keyboard
