How to enter flash mode

Hold down POWER + Vol Down while booting to enter Flash Mode.

Wifi

Configure your kernel and enable the prima wifi staging driver

pmbootstrap menuconfig motorola-harpia
pmbootstrap build linux-motorola-harpia

On the device

apk add wcnss-wlan
/etc/init.d/wcnss-wlan start

Firmware {Wifi/Modem} (TODO: package it)

On the device extract firmware

cd /lib/firmware
mkdir postmarketos
cd postmarketos
mount /dev/disk/by-partlabel/system /mnt
cp -ap /mnt/etc/firmware/* /lib/firmware/postmarketos
umount /mnt
mount /dev/disk/by-partlabel/fsg /mnt
cp -ap /mnt/* /lib/firmware/postmarketos
umount /mnt
mount /dev/disk/by-partlabel/modem /mnt
cp -ap /mnt/image/* /lib/firmware/postmarketos
umount /mnt
mount /dev/disk/by-partlabel/persist /mnt
mkdir -p wlan/prima
cp -ap /mnt/WCNSS_wlan_dictionary.dat wlan/prima/
umount /mnt

Make a link in case the firmware path doesn't include /lib/firmware/postmarketos

cd /lib/firmware
ln -s /lib/firmware/postmarketos/* /lib/firmware/


Modem

Make the necesary links for qcom_rmtfs

cd /boot
ln -s /dev/disk/by-partlabel/modemst1 modem_fs1
ln -s /dev/disk/by-partlabel/modemst2 modem_fs2
ln -s /dev/disk/by-partlabel/fsg modem_fsg

Install necessary software

apk add modem-qcom-msm-downstream-common qcom_rmtfs libsmdpkt_wrapper libqipcrtr4msmipc ofono

Start the wcnss-wlan service to initialize the wifi card (helps the modem?)

/etc/init.d/wcnss-wlan start

Start a tmux for multiple windows tmux

Start qcom_rmtfs on a terminal

export LD_PRELOAD=/usr/lib/preload/libqipcrtr4msmipc.so
qcom_rmtfs -v

Start ofonod on another terminal

export LD_PRELOAD=/usr/lib/preload/libsmdpkt_wrapper.so
ofonod -d -n

Send an SMS!

export PHONE_NUMBER="<number to send sms to ex: 1234567890>"</code>
