Usually I dot my laptop with READMEs in various ~/devel/ subdirs, but in this case I decided to write up some notes here. These are mostly for my own reference, but perhaps they will be of use to you.
I have stopped development on Meego/Maemo, so these pages are getting quickly dated. Ciao!

==Too mucha programmaz==
* [http://maemo.org/profile/view/jebba/ Maemo profile]
I bricked my N900 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...

==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:
* Usually I dot my laptop with READMEs in various ~/devel/ subdirs, but in this case I decided to write up some notes here. These are mostly for my own reference, but perhaps they will be of use to you.
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).

==Flashing with Nokia's Proprietary maemo_flasher==
=Package Building HOWTO=
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_tablet_firmware | Updating tablet firmware]] on this wiki.
The [[User:Jebba/Package Building HOWTO|Package Building HOWTO]] now has its own page. :)


* To get the most recent image from Nokia, go here: http://tablets-dev.nokia.com/nokia_N900.php
=Kernel=
* Enter product ID inside the phone (without "/"s)
The new [[User:Jebba/Kernel|kernel page]]
* 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.


=Post debrick setup=
=Freemoe git=
Now that the device is debricked, I can use the thing again and "all" my data is there, but the repository setup is back to default and the applications I want are gone, amongst other things. To re-setup:
