Hi all,

my N9 encountered a sudden death, maybe you can help me narrowing down the problem...

It just turned off in my pocket, no button no led no charging anymore..

I took the screen off and reconnected the battery but still the same - what else can I do to narrow down the problem?

Should the phone work without battery connected only to the charger?

Would be very surprised if worked without battery in place. Do you get any response if connecting to PC and using Harmattan flasher? See here for more detail: http://talk.maemo.org/showthread.php?t=82693

I'd do what aspergerguy said, and see if it charges with the flasher utility. (I think I'd try that before disassembling it, but that's water under the bridge now.) The thread he pointed out has plenty of help in it to get started.

Unfortunately, I have to add that this is the manner in which my first N9 died, not to be revived. It would flash, but never turned on again. I was able to save important data with the "fixing MALF state" procedure and exporting and mounting the phone's partitions.

thank you, I'll try and report..

So I connected the phone using "flasher -i" and there is zero response, whether from flasher nor from phone..

So that was about it?!

Before leaving it for dead, it would be a good idea to make sure that flasher itself is working. Maybe post the output here. If possible check the USB port, cable and computer used by swapping those components out one at a time. Several users flashing their phones had non-working cables, ports and OSs to contend with on top of the phone troubles. Do you have access to another N9 so you can perform a "sanity check" on your setup?

Good luck.

this is the output for "sudo flasher -i" in linux shell
Code:
flasher 3.12.1 (Oct  5 2011) Harmattan
WARNING: This tool is intended for professional use only. Using it may result

Suitable USB interface (bootloader/phonet) not found, waiting...
I had switched USB port and the cable, all of which I know they work, and nothing happens. It doesn't list anything with lsusb either. I don't have another N9, I could try with Windows... but this should work

Possibly just fully empty battery?

Try the flasher trick to charge battery (up to 10%).
And add --flash-only=kernel to not overwrite data on your device if flasher starts immediately.

--edit
If that does not help (please provide outputs) I assume either a dead battery or an USB (other HW) failure.

What does dmesg say?

dmesg says ..erm well nothing. And the flasher won't do magic when it can't recognize the phone.

I would try so.
As totally depleted battery may act so, too.

But first search a post here by finnish guy whose N9 (left in winter in car overnight) acted similar to yours.
He could get it charging again by either just opening and reconnecting or charging battery outside device (cannot remember).
A new battery should work too. But as you need topen anyway try that first.

N9 revived again!!!

I found the thread you mentioned
http://talk.maemo.org/showthread.php?t=91722
and thought well, give it a second try...

So I let the battery plugged off for ~10min and replugged everything - and got a LED blink.. The joy was short, while reassembling a sudden cloud of electronic dust and the typical short circuit smell came out of the top right corner. I unplugged as fast as I could and saw the display cable (the one with the wide plug) was damaged on the outer side of a bend and had gotten contact with the metal cage in the housing.

I couldn't break any more so I just isolated the damaged cable area - put it back together and voilą - up and running.

The damage must have occured when I opened the device 2 months ago.

I thank all of you, appreciate your help very much.
