I know there's a thousand threads about n900's not turning on bla bla blaaaaa. So please don't tell me to do a search because i've just spent the last hour doing so and found no answer. This n900 came from a friend who initially lost it, had another handset sent to him by voda and then he found the first handset again but never used it since. Anyway, my bird works for voda and she checked the imei number to see if its on their blacklist but it isn't.. So the problem.. phone switches on, Nokia appears on the screen followed by the dots, freezes then turns off. I've flashed both images like 10 times with no difference. Any idea's anyone?? The phone worked fine before it was lost so there's no reason it shouldn't work now right?
Thanks in advance

Just FYI, flasher on Windows can't enable R&D Mode last I checked. You'd need to use a Linux distro's Live CD an run the Linux flasher from that.
ALSO, abill_uk: Have you ever talked to, or heard/read anyone mention, how their N900 acted when blacklisted? There is no way in hell I can see that logically fitting blacklisting - because the N900 can boot without a sim card and without a functional cellphone plan. (Just in case you are right - guy with the problem, can you try booting without the sim card inserted and see if it makes a difference?) He also said that they checked with Vodaphone already, and they don't have the IMEI blacklisted.
Do vi_'s suggestion please - post the output of the flasher. ALSO, try reflashing the bootloader. (I don't really know much on the subject of using flasher for that, though.)
Other than that, hardware damage is possible. You can also try to use framebuffer kernel, flash it onto the device using the --kernel flag on the kernel image, and see if you can tell what the problems are - if you get all the way to loading dots, framebuffer console SHOULD show you the errors (though it might take a bunch of tries at seeing the errors and reading them fully in the rapidly scrolling console output).

How do we know it has not been turned on long enough to sign on and do the hand shake because that is all it takes for the device to be blocked totally, never to work again if it is flagged like that.
Was only a suggestion OK.
And as you rightly said a re-flash will cure it if not flagged.

But the point is, you have to actually think about the phones you're talking about. Some dumbphone is very likely to appear bricked when blacklisted - some might just fail to boot if they aren't able to connect to the network. But I don't think it would make sense to assume all phones self-brick just because they get a "you're blacklisted" event from a cell tower.
The ONLY posts I remember from a user who seemed to have their N900's IMEI blocked (a user named Zimon - you can look up more indepth info if you'd like, or search for others) said he could boot fine, just couldn't connect to the networks of some of the providers in his area, but could connect to some other networks.
Also, if the starter of this thread lives in the USA, carriers never IMEI blacklist, based on what I've heard. (Verizon does, but that's for CDMA network equivalents of the IMEI, which isn't relevant since the N900 doesn't connect to CDMA anyway.)

Yes you very very right there as i have found also same as you as some will boot and some won't so i can only guess it is the level of "blocking", imei flagging can have different effects on even same model devices, weird isnt it.
I could go a lot deeper into this because of the work i used to do but i don't think this is the place for that, suffice to say emei is the key and once you turn that around you get results
.
But as you rightly said it is most likely only a re-flash it needs hopefully.
I am waiting for the end result from the op and hope it is good news.
Anyhow thanyou for your comments as i do also read many of your very intellectual posts hehehe and enjoy too.

To change to R&D mode you need to have flasher installed and run:
In linux:
flasher-3.5 --enable-rd-mode
In windows
flasher-3.5.exe --enable-rd-mode
In case it boots up in this mode, you should take a look to this thread: http://talk.maemo.org/showthread.php...82#post1047282

Unfortunatly i don't 
I'd try everything you've said but wouldn't know how? All i can do is flash the fiasco and emmc, thats as far as my intelligance goes. But there has been some progress as it boots in r&d mode whatever that is
It most definatly isn't on voda's blacklist like i said earlier and i live in the uk and the device seems to work fine in r&d mode except it won't charge and says the batterys flat when it isn't. I've just tried my tmobile sim in it and it picks up the network no problem too. What else can i try guys??

Well, it appears that you have the exact same problem as me... Take a look to this thread: http://talk.maemo.org/showthread.php?t=63259
Maybe you could explain there what happened to the device: did you overclocked it? have an accident, maybe water or it just fell?
I appreciate your comments to see if we could solve this! For now, it seems to be a battery monitor/state damage...

Then turn off device, use flasher to disable R&D mode (but don't reflash) and see if it'll boot.
... and the device seems to work fine in r&d mode except it won't charge and says the batterys flat when it isn't. I've just tried my tmobile sim in it and it picks up the network no problem too. What else can i try guys?? ...
If you want help with the frambuffer kernel too, let me know and I'll write up more detailed instructions when I get the chance.

Try booting.
Failing that enable R&D mode, then post the output.
Try booting.
Failing that the thing is probably fooked, however I find that hard to believe as it is extremely hard to brake one. (USB Whingers need not apply).
