<h1>samsung g800f (Samsung Galaxy S5 mini)</h1>
<h2>Basic info</h2>
<p>Device: Samsung Galaxy S5 mini (SM-G800F; European version)</p>
<p>Cortex A7 (32 bit ARM), quad core 1.4GHz; 1.5GB RAM, 16GB storage.</p>
<ul>
<li><a href="http://www.gsmarena.com/samsung_galaxy_s5_mini-6252.php">more specs</a></li>
<li><a href="https://github.com/cm-3470/android_device_samsung_kminilte">Unofficial LineageOS repo</a></li>
<li><a href="https://github.com/cm-3470/android_kernel_samsung_kminilte">Unofficial LineageOS kernel repo</a></li>
</ul>
<h3>How to enter flash mode</h3>
<p>Press and hold "volume down + home + power" simultaneously. Then click volume up to confirm.</p>
<h3>Problems</h3>
<ul>
<li>Currently, Heimdall seems to be unable to flash the device's <code>SYSTEM</code> partition, so we can't do the entire install using just <code>pmbootstrap flasher</code>.</li>
<li><code>udevadm trigger</code> causes a complete system freeze and eventual reboot. If you comment out that line in <code>start_weston.sh</code> and replace it by <code>udevadm trigger --attr-match=name=sec_touchscreen</code>, the touch screen should work.</li>
</ul>
<h3>Preparing for install</h3>
<p>First, <a href="https://eu.dl.twrp.me/kminilte/">download the TWRP recovery ROM</a>. You'll need both the <code>.img.tar</code> and the <code>.img</code> file. First, extract the tar file to obtain <code>recovery.img</code>. Then, put your phone in flash mode and flash using Heimdall:</p>
<pre class="codehilite"><code>$ heimdall flash --RECOVERY recovery.img --BOOT twrp-3.1.1-1-kminilte.img</code></pre>
<p>Now you should be able to connect to the device using <code>adb</code>.</p>
<h3>Installing system</h3>
<p>Follow <a href="https://github.com/ata2001/android-recovery-zip">the android-recovery-zip steps</a>, substituting <code>samsung-g800f</code> for <code>your-device</code> in all the commands. If you get an error <code>lddtree not found</code>, simply run <code>apk add lddtree</code> in the chroot environment and try again.</p>
<p>If you get the following errors:</p>
<pre class="codehilite"><code>device-mapper: reload ioctl on failed: No such file or directory
Failed to setup dm-crypt key mapping for device /dev/block/mmcblk0p18.
Check that kernel supports aes-xts-plain64 cipher (check syslog for more info).</code></pre>
<p>You can try to reinstall with a different cipher, by editing <code>install_options</code> and changing the <code>CIPHER</code> line to <code>CIPHER="aes-cbc-plain64"</code>, re-zipping and using <code>adb sideload</code> again.</p>
<h3>Installing kernel</h3>
<p>This can be done via <code>./pmbootstrap.py flasher flash_kernel</code></p>
<p>It should boot, and show the Samsung splash screen. After that you should be able to <a href="https://github.com/postmarketOS/pmbootstrap/wiki/Boot-process">connect via telnet</a></p>
