<li>ollieparanoid</li>
<li>PabloCastellano and robb4 on IRC: Workaround for red screen bug <a href="https://github.com/postmarketOS/pmbootstrap/issues/54">#54</a></li>
</ul>
<h3>Entering "Fastboot mode"</h3>
<p>Hold <code>Volume Down</code> + <code>Power</code>, let go of <code>Power</code> once the device display does something (e.g. turns from battery icon to black screen).</p>
<h3>What works</h3>
<ul>
<li>Touchscreen</li>
<li>Weston (has the red screen bug, but we have a workaround for that now 👍 )</li>
</ul>
<h3>What does not work</h3>
<ul>
<li>XWayland</li>
<li>The rest (Wifi, bluetooth, making calls, ...)</li>
<li>fbsplash only displays splash images very shortly, then goes to black screen</li>
</ul>
<h3>Wifi</h3>
<p>Looks like, we need to package the <a href="https://github.com/LineageOS/android_device_lge_mako/blob/12ac6e9aeb32d5ac9fc832f2214ede2c7690d0a6/proprietary-blobs.txt#L152-L157">wcnss.* files</a> for wifi. A version from 2015 can be found <a href="https://github.com/TheMuppets/proprietary_vendor_lge/tree/cm-14.1/mako/proprietary/vendor/firmware">here</a>. It's a Qualcomm chip.</p>
<h3>Alternative kernels</h3>
<p>These are not packaged yet in postmarketOS, feel free to package them.
