hi
i have the n900 and now is not working
all it does is power on with the logo then go off after about 30 sec or so and wont boot up at all ???????
help please

most likely battery needs charging.. put it on charge and leave it for 5mins and try again.

if that did work, I guess you'll need to reflash it.

can you tell me how to do it please
as tried the hold the u button but that didn't work or am i doing it wrong

Just relax, and carefully search TMO - You will find answer how to reflash Your device (if that is really what it's need). Don't worry and find enough time to read few threads about that kind of cases.

First things first, start from the most obvious things (like bingomion says), battery, etc.

It will be all right, just don't try everything without knowing what You're dooing. Write some more info about Your case, what You did with it before she decided to sleep little longer There is louds of great people here willing to help and having right skillzz for dooing so.

here is a pretty easy flashing guide ( i used it with my first reflash try :P ).

and here is the wiki page for more accurate info.

btw i did not got these 2 links from another planet all from the power search button !


Good luck

Not the battery as got a new one with a charger incase was the changing port but still just the nokia logo then off. I was taking it back to a backup. As i had tride to put whatsapp on well the n900 one anyway so must of done something to the settings

all i get when trying to flasher it is suitble usb not found
can anyone tell me what im doing wrong .or am i using the wrong flasher ?

What operating system do you use?
If you use windows 7 64-bit you will need libusb (choose the latest version)
This should install the drivers you need to flash your N900

all im getting is this now
thort i was good at phones lol
not having good luck this week

im stuck at this state..it lasts about 30 secs then off..if i plug it thru pc, it goes on reboot loop still lasts for 30 secs then boot again and again..holding u button is not working..
