I have found a way to "de-brick" a device that does not require reflashing.

If your device is booting up and hung with the second dot lit, like:

==Too mucha programmaz==
 
-
I bricked my N900 (December 3rd) by adding the extras-testing + extras-devel repos and then installing lots of applications. I hit 100% on / (root filesystem) and on reboot the system hung at the "dots" part, ala:
 
-
 
-
  * (*) * * *
 
-
 
-
I had filled up to 100% a number of times before and rebooting the phone had '''cleared''' up space (e.g. 100% full before reboot, 96% full after reboot). This is likely because 5% or so is reserved for root. Anyway, the most recent time it didn't come back alive...
 
-
 
-
===Gah, bricked again===
 
-
I was "participating" in the "[http://talk.maemo.org/showthread.php?p=414650 Bug] [[Bugsquad#Bugdays|day]]", when someone suggested installing gettext to look at translations. I installed this, but got up to 99% full. I then did an `apt-get clean` to empty the cache and this dropped me to 98% full. I've often booted gnulinux boxes with 99% (or even 100%) full, so I figured 98% was fine. I wanted to reboot because often when you reboot the N900, you get space freed, due to the icon cache being liberated. Anyway, on reboot, I got a brick exactly as described above with the second dot more lit than the others (which I have seen reported by others):

This time I have my handy kernel with a console, so I can actually see WTF is going on. [http://www.freemoe.org/users/jebba/MALF/ The images here show some details]. In sum, things booted up and the root filesystem check went fine. Then it got an error right after "Freeing Init memory 152K" like this:
 
-
 
-
getbootstate: Unexpected reset count 50 exceeds maximum (51)
 
-
getbootstate: Entering state 'MALF'.
 
-
getbootstate: Houston, we have a problem, powering off...
 
-
 
-
The /sbin/getbootstate program is in the package "getbootstate". But look at this and hold back the tears:
 
-
 
-
[sbox-FREMANTLE_ARMEL: ~/getbootstate] > apt-get source getbootstate
 
-
Reading package lists... Done
 
-
Building dependency tree... Done
 
-
E: Unable to find a source package for getbootstate
 
-
 
-
The getbootstate package appears to be closed source. :( That pretty much ends the debugging and my bug day. Gah.

==Flashing N900 with 0xFFFF==
 
-
Many parts of the N900 are Free Software, but lamentably, many parts are still closed proprietary shit. Nokia's maemo_flasher program is an example of a closed application that Nokia makes for use with the N900. I understand why some parts of their suite are still closed (e.g. pre-ofono GSM stack), but why the flasher has to be closed I have no idea. Gar.
 
-
 
-
Thankfully, there is [http://www.nopcode.org/0xFFFF/ The 0pen Free Fiasco Firmware Flasher], which is designed for flashing Nokia tablets and is [http://www.gnu.org/philosophy/free-sw.html Free Software] (GPLv3). Unfortunately, 0xFFFF doesn't work with the N900. There is [http://www.mail-archive.com/0xffff@lists.nopcode.org/msg00072.html some progress to support the device]. You can grab the most recent code from the mercurial repository thusly:
 
-
hg clone http://hg.youterm.com/0xFFFF
 
-
 
-
I sent the author of 0xFFFF the output of my crash. Hopefully it will soon be a usable tool for flashing the N900. I built RPMs for Fedora 12 x86_64 running the latest mercurial code--the ones in the Fedora repo aren't even the lastest tarball release (0.3.9 vs. 0.4.0).
 
-
 
-
===0xFFFF for Fedora===
 
-
* NOTE: recently I checked out the code via Mercurial and saw that the 0xFFFF developer has added much more N900 specific code, but I haven't tried it yet.
 
-
 
-
* UPDATE: I have built the latest and greatest code of 0xFFFF from today and made a Fedora 12 package. You can grab it here:
 
-
 
-
Binary:
 
-
* [http://www.freemoe.org/users/jebba/fedora/12/x86_64/0xFFFF-0.4.0-0jebba.fc12.x86_64.rpm 0xFFFF-0.4.0-0jebba.fc12.x86_64.rpm]

-
 
-
* The 0xFFFF GUI uses [http://code.google.com/p/gtkaml/ gtkamlc]. This is not packaged in Fedora. I built it, but compiling the GUI is still barfing.

==Flashing with Nokia's Proprietary maemo_flasher==
 
-
I [http://wiki.blagblagblag.org/Roadmap now] have ONE non-free program installed on my computer  :(  It's the only way I know how to debrick the phone.
 
-
 
-
See also: [[Updating_the_firmware | Updating tablet firmware]] on this wiki.
 
-
 
-
* To get the most recent image from Nokia, go here: http://tablets-dev.nokia.com/nokia_N900.php
 
-
* Enter product ID inside the phone (without "/"s)
 
-
* Grab RX-51_2009SE_1.2009.42-11_PR_COMBINED_MR0_ARM.bin or whatever is current.
 
-
* To get the proprietary stinking pile of poo, go here: http://tablets-dev.nokia.com/maemo-dev-env-downloads.php
 
-
* Grab maemo_flasher-3.5_2.5.2.2.tar.gz or most recent.
 
-
* In Fedora 12 x86_64 I had to install some i686 libraries since my system is 64-bit. So:
 
-
yum -y install glibc.i686 libusb.i686
 
-
* Untar the files....
 
-
* Power off phone and unplug USB.
 
-
* Hold down "u" on N900 keyboard and plug in USB cable between computer and N900. A USB icon will appear in the upper right corner--you can let go of "u" on the keyboard at this point.
 
-
* Run this as root:
 
-
./flasher-3.5 -F ~/devel/maemo/FLASH/RX-51_2009SE_1.2009.42-11_PR_COMBINED_MR0_ARM.bin -f -R
 
-
* Done.

[http://en.wikipedia.org/wiki/Virtual_Network_Computing VNC] allows you to view the screen of the N900 on your laptop so you can do things more easily that having to use the tiny little thing if you are working on it all day.
 
-
 
-
* Set up the [[Extras-testing]] repository
 
-
* Install x11vnc (I ''think'' it's in -testing).
 
-
* Set up a password for VNC on on the N900:
 
-
x11vnc -storepasswd
 
-
* Run this script on your laptop (my hostname is burger and my laptop's IP is 10.0.0.3):
 
-
 
-
ssh -n user@burger \
 
-
        "x11vnc \
 
-
        -usepw \
 
-
        -display :0 \

-
        -bg \
 
-
        -o /home/user/vnc-log \
 
-
        "
 
-
* This works fine with tigervnc on Fedora 12.
 
-
 
-
* Running x11vnc with "-ssl" does not work--I think the problem there may be with tigervnc as x11vnc starts with it OK.
 
-
 
-
* I usually do VNC in an ssh tunnel--I don't know if this would create too much of a load on the N900 or not. Will test.
 
-
* VNC behaves differently whether the keyboard is slid out or not. Basically, you want the keyboard out.
