{{note|FDE (full disk encryption) seems to be broken for lg-mako currently, see {{issue|209|pmaports}}}}

pmbootstrap init
pmbootstrap install
(enter fastboot, see below)

pmbootstrap flasher boot
</pre>
You can properly turn the device off by unplugging the usb cable, then booting into fastboot, then choosing power off.
== What works Wifi ==Looks like, we need to package the [https://github.com/LineageOS/android_device_lge_mako/blob/12ac6e9aeb32d5ac9fc832f2214ede2c7690d0a6/proprietary-blobs.txt#L152-L157 wcnss.* files] for wifi. A version from 2015 can be found [https://github.com/TheMuppets/proprietary_vendor_lge/tree/cm-14.1/mako/proprietary/vendor/firmware here]. It's a Qualcomm chip.
* Touchscreen== Mainline ==* Weston (has the red screen bug, but we have {{note|See [[The Mainline Kernel]] for a workaround for that now 👍 )general introduction to mainlining.}}

== Wifi ==This means, that most peripherals of the <code>mako</code> should work with mainline as well, once they are enabled in the DTS file. In fact, @vetzki reported in {{github|1079}} that the <code>mako</code> boots when using exactly the same DTS as the one from <code>flo</code> (this is not recommended, as misconfiguring your device like that may damage it). SSH appears to be working for a short time before getting kicked out, the display does not work.
Looks likeA good way forward would be using a minimal version of the <code>flo</code> DTS, we need where everything but USB is deleted, and fixing USB / trying to package get the display working with the [https://github.com/LineageOSfreedreno/android_device_lge_makofreedreno/blobwiki/12ac6e9aeb32d5ac9fc832f2214ede2c7690d0a6/proprietaryDSI-Panel-blobs.txt#L152Driver-L157 wcnssPorting DSI Panel Porting Guide].* The downstream DTSI files] for wifi.
