+ <div class="date"> 7th July 2016</div>
+ <div class="body"><p>Yesterday, I tried to unlock a HTC Desire HD phone, and it proved
+to be a slight challenge. Here is the recipe if I ever need to do it
+again. It all started by me wanting to try the recipe to set up
+<a href="https://blog.torproject.org/blog/mission-impossible-hardening-android-security-and-privacy">an
+hardened Android installation</a> from the Tor project blog on a
+device I had access to. It is a old mobile phone with a broken
+microphone The initial idea had been to just
+<a href="http://wiki.cyanogenmod.org/w/Install_CM_for_ace">install
+CyanogenMod on it</a>, but did not quite find time to start on it
+until a few days ago.</p>
+
+<p>The unlock process is supposed to be simple: (1) Boot into the boot
+loader (press volume down and power at the same time), (2) select
+'fastboot' before (3) connecting the device via USB to a Linux
+machine, (4) request the device identifier token by running 'fastboot
+oem get_identifier_token', (5) request the device unlocking key using
+the <a href="http://www.htcdev.com/bootloader/">HTC developer web
+site</a> and unlock the phone using the key file emailed to you.</p>
+
+<p>Unfortunately, this only work fi you have hboot version 2.00.0029
+or newer, and the device I was working on had 2.00.0027. This
+apparently can be easily fixed by downloading a Windows program and
+running it on your Windows machine, if you accept the terms Microsoft
+require you to accept to use Windows - which I do not. So I had to
+come up with a different approach. I got a lot of help from AndyCap
+on #nuug, and would not have been able to get this working without
+him.</p>
+
+<p>First I needed to extract the hboot firmware from
+<a href="http://www.htcdev.com/ruu/PD9810000_Ace_Sense30_S_hboot_2.00.0029.exe">the
+windows binary for HTC Desire HD</a> downloaded as 'the RUU' from HTC.
+For this there is is <a href="https://github.com/kmdm/unruu/">a github
+project named unruu</a> using libunshield. The unshield tool did not
+recognise the file format, but unruu worked and extracted rom.zip,
+containing the new hboot firmware and a text file describing which
+devices it would work for.</p>
+
+<p>Next, I needed to get the new firmware into the device. For this I
+followed some instructions
+<a href="http://www.htc1guru.com/2013/09/new-ruu-zips-posted/">available
+from HTC1Guru.com</a>, and ran these commands as root on a Linux
+machine with Debian testing:</p>
+
+<p><pre>
+adb reboot-bootloader
+fastboot oem rebootRUU
+fastboot flash zip rom.zip
+fastboot flash zip rom.zip
+fastboot reboot
+</pre></p>
+
+<p>The flash command apparently need to be done twice to take effect,
+as the first is just preparations and the second one do the flashing.
+The adb command is just to get to the boot loader menu, so turning the
+device on while holding volume down and the power button should work
+too.</p>
+
+<p>With the new hboot version in place I could start following the
+instructions on the HTC developer web site. I got the device token
+like this:</p>
+
+<p><pre>
+fastboot oem get_identifier_token 2>&1 | sed 's/(bootloader) //'
+</pre>
+
+<p>And once I got the unlock code via email, I could use it like
+this:</p>
+
+<p><pre>
+fastboot flash unlocktoken Unlock_code.bin
+</pre></p>
+
+<p>And with that final step in place, the phone was unlocked and I
+could start stuffing the software of my own choosing into the device.
+So far I only inserted a replacement recovery image to wipe the phone
+before I start. We will see what happen next. Perhaps I should
+install <a href="https://www.debian.org/">Debian</a> on it. :)</p>

- <div class="date"> 8th May 2016</div>
- <div class="body"><p><strong>Where I set out to figure out which multimedia player in
-Debian claim support for most file formats.</strong></p>
-
-<p>A few years ago, I had a look at the media support for Browser
-plugins in Debian, to get an idea which plugins to include in Debian
-Edu. I created a script to extract the set of supported MIME types
-for each plugin, and used this to find out which multimedia browser
-plugin supported most file formats / media types.
-<a href="https://wiki.debian.org/DebianEdu/BrowserMultimedia">The
-result</a> can still be seen on the Debian wiki, even though it have
-not been updated for a while. But browser plugins are less relevant
-these days, so I thought it was time to look at standalone
-players.</p>
-
-<p>A few days ago I was tired of VLC not being listed as a viable
-player when I wanted to play videos from the Norwegian National
-Broadcasting Company, and decided to investigate why. The cause is a
-<a href="https://bugs.debian.org/822245">missing MIME type in the VLC
-desktop file</a>. In the process I wrote a script to compare the set
-of MIME types announced in the desktop file and the browser plugin,
-only to discover that there is quite a large difference between the
-two for VLC. This discovery made me dig up the script I used to
-compare browser plugins, and adjust it to compare desktop files
-instead, to try to figure out which multimedia player in Debian
-support most file formats.</p>
-
-<p>The result can be seen on the Debian Wiki, as
-<a href="https://wiki.debian.org/DebianMultimedia/PlayerSupport">a
-table listing all MIME types supported by one of the packages included
-in the table</a>, with the package supporting most MIME types being
-listed first in the table.</p>
-
-</p>The best multimedia player in Debian? It is totem, followed by
-parole, kplayer, mpv, vlc, smplayer mplayer-gui gnome-mpv and
-kmplayer. Time for the other players to update their announced MIME
-support?</p>
