== Installation ==

Hardware requirements:

* Droid4 with fully charged battery
* MicroUSB cable
* MicroSD card

Software requirements:
* Host Linux or Windows system
* Android Tools: fastboot
* Flashing tools:
** XZ Utils and coreutils for Linux
** Etcher[https://github.com/balena-io/etcher] for Windows

Download from https://maedevu.maemo.org/images/droid4/

# VRZ_XT894_9.8.2O-72_VZW-18-8_CFC.xml.zip
# flash-droid-4-fw.sh
# Latest maemo-leste-1.0-armhf-droid4-*.img.xz

Download from https://github.com/tmlind/droid4-kexecboot.git

# utags-mmcblk1p13.bin
# droid4-kexecboot.img

Check what kernel version your Android OS runs.
For this go to Settings -> About phone. Slide to the bottom, where you can see "Kernel version".
If you have at least 3.0.8, you may skip "Updating Android" step below.

Installation:

# Create a working directory with above mentioned files in it
# unzip VRZ_XT894_9.8.2O-72_VZW-18-8_CFC.xml.zip
# Power off Droid4 and connect it to the host machine with MicroUSB cable
# Start the device in fastboot mode. For this press power button and bottom volume key simultaneously and release them after a second.

=== Updating Android ===

This will reinstall the Android OS on your device, deleting all user data. Do a backup, if you want to save something. When everything is ready, go to the working directory mentioned above and run:
<pre>
pushd VRZ_XT894_9.8.2O-72_VZW-18-8_CFC.xml
sudo bash ../flash-droid-4-fw.sh
popd
</pre>

=== Setting up kexecboot ===

Now, assuming you are in the working directory, install kexecboot:

<pre>
sudo fastboot flash mbm VRZ_XT894_9.8.2O-72_VZW-18-8_CFC.xml/allow-mbmloader-flashing-mbm.bin
sudo fastboot reboot-bootloader
sudo fastboot flash bpsw droid4-kexecboot.img
sudo fastboot flash utags utags-mmcblk1p13.bin
sudo fastboot reboot
</pre>

If you did "Updating Android" the device should run the firstboot steps.
If you didn't, the device should reboot and show kexecboot menu for a few seconds before it boots to Android.

=== Install Maemo Leste to the sdcard ===

Now, flash the Maemo Leste image to your sdcard:

On Linux:
<pre>
xzcat maemo-leste-1.0-armhf-droid4-20190227.img.xz | sudo dd status=progress bs=1M of=/dev/MICROSDCARD-DEVICE
sync
</pre>

On Windows: Use Etcher

Wait for sync to complete and insert MicroSD card into Droid4. Reboot the device and select Maemo Leste from the kexecboot menu.

You should now see Maemo Leste booting up, and it will show you hildon-desktop after a minute.

== Updating ==

Normally you can just apt update && apt dist-upgrade to update to the latest version. If for some reason this fails:

* Poweroff device, grab the SD card
* Backup any important files
* Grab the latest image from https://phoenix.maemo.org/view/Images/
* Write it as before : xzcat maemo-leste-1.0-armhf-droid4-20190227.img.xz | sudo dd status=progress bs=1M of=/dev/MICROSDCARD-DEVICE

== Notes ==

The battery in Droid4 is not easily removable. If you got the device stuck, use this combo: power button + bottom volume key. You should hold them for about 7 seconds. Droid4 will then reboot.

If Maemo is still running, you can also hold just the power button for ~10 seconds, and the device will run poweroff.

Some users reported that Bluetooth kernel module interfere badly with the WiFi driver on their devices.
Blacklisting the module may help if you have such problems:
echo "blacklist hci_uart" >> /etc/modprobe.d/blacklist.conf

Also see [[Motorola_Droid_4/Modem]] [[Motorola_Droid_4/PowerVR]]

Also see: http://elektranox.org/droid4/ and http://muru.com/linux/d4/

The keyboard layout is extended to provide more standard keys.
[[File:Maemo-leste-droid4-kbd-2021-07.png|center|620px|thumb|maemo-leste droid4 keyboard]]
Key mapping can be tested with the 'xev' program.

It may be necessary to run the follow commands as root in order to get the OK key to function correctly (see [https://github.com/maemo-leste/bugtracker/issues/510#issuecomment-815618591 here]):
udevadm hwdb --update
udevadm trigger

== Serial Cable ==

As explained at http://muru.com/linux/d4 , the Droid 4 exposes a serial console on the USB port. You can construct the required cable easily by following the instructions there. If you have old Nokia CA-42 or DKU-5 cables, then you can use them with the Droid 4, using instructions at https://jethomson.wordpress.com/2010/02/21/diy-usb-to-serial-cable-for-3usd/

While using the serial cable, if you lose the connection, the following may help:

<pre>
18:43 < tmlind> sicelo: hmm the uart debug cable multiplexing still has issues, if the uart disappears during boot it should come back with
the console login propt later
18:45 < tmlind> try plugging in a pc usb cable then back to uart cable in case that might help
</pre>

== Bluetooth ==

Needs firmware - install latest firmware-ti-connectivity - See also https://github.com/maemo-leste/bugtracker/issues/290. Due to interference with WiFi, load driver manually, AFTER wifi module loaded. So you should do:

<pre>
sudo apt install firmware-ti-connectivity
sudo modprobe hci_uart
sudo hciconfig hci0 up
sudo hcitool lescan
</pre>

== Stuff to try ==

==== Using a battery without temperature sensor ====

Modprobe the pmic driver as follows:
<pre>
cpcap-battery ignore_temperature_probe=1
</pre>

==== Flashing the boot logo ====

More info: https://github.com/xsetiadi/droid4-kexecboot/blob/master/LOGO

<pre>
15:04 < tmlind> Wizzup: i think the logo on droid4 can be flashed with fastboot flash logo logo.bin or something, can also be just written to logo partition from m-l
[snip]
09:24 < xsetiadi> https://github.com/xsetiadi/droid4-kexecboot/blob/master/logo.bin
09:25 < xsetiadi> becarefull, you can bootloop droid4 if you wrong flash partition
09:26 < xsetiadi> like i do last year
09:26 < xsetiadi> instead of flashing using command: fastboot flash logo.bin logo.bin i just flash it with command: fastboot flash logo logo.bin
</pre>

==== Blinkenlights ====
Adding this in rc.local above the ''exit 0'' gets you some blinkenlights to watschen und relaxen.
echo cpu > /sys/class/leds/lm3532::kbd_backlight/trigger # gets you a cpu activity monitor on the keyboard backlight
echo mmc0 > /sys/class/leds/shift-key-light/trigger # gets you a 'hdd led' of the SD card on the capslock light

==== USSD ====

<pre>
22:45 < tmlind> fyi, here's how to send USSD to query balance for example: printf "AT+CUSD=1,#999#,0\r" > /dev/motmdm1
22:47 < tmlind> fyi, for parsing incoming USSD, this web interface works if set to utf-8:
https://www.mobilefish.com/services/latin_utf_base64_to_hex/latin_utf_base64_to_hex.php#text_hex_output
</pre>

==== HDMI ====
Move output to external 1080p monitor. Disabling DSI-1 output gets xorg pointer displayed on HDMI, for use with a mouse or barrier.
<pre>
xrandr --output HDMI-1 --mode 1920x1080 --output DSI-1 --off
</pre>
Return to internal touchscreen display.
<pre>
xrandr --output DSI-1 --auto --rotate right --output HDMI-1 --off
</pre>

==== Keyboard / Mouse sharing with PC ====
To use droid4 while working at desktop it can be convenient to share mouse and keyboard of the host pc with droid4.
<pre>
[https://github.com/debauchee/barrier Barrier software-KVM switch]
</pre>
Developers and testers may wish to disable the googley bits before compiling.

==== BT Audio headset ====

sudo apt install pulseaudio-module-bluetooth blueman bluez
sudo modprobe hci_uart
pactl load-module module-bluetooth-discover
blueman-manager

Pair & trust your device in blueman, connect audiosink. You can close blueman now. The quality seems a bit better in 'offline mode'.

==== Torch ====

The Droid 4 has a TI LM3559 flash torch controller. This provides flash functionality when taking pictures, usage as a torch, and provides privacy indication (in this mode, the LED flashes in a fast heartbeat pattern). A driver for it exists in mainline, but it requires some DTS work, since it is tied to a camera device.

If you want to use it in the meantime, direct i2c access can be used as follows (since this is direct access, be careful about each of the commands below):

<source>
##Install the prerequisites
$ sudo apt install i2c-tools

## Turn LED on in torch mode
$ sudo i2cset -y 2 0x53 0x10 0x1a

## Turn LED on in privacy indication mode
$ sudo i2cset -y 2 0x53 0x10 0x19

## Turn LED off (in any mode)
$ sudo i2cset -y 2 0x53 0x10 0x18

## Use LED for doing a hella bright flash for some time once and then turn off
$ sudo i2cset -y 2 0x53 0x10 0x1b

</source>

== Using a configured Leste sdcard in a different Droid4 ==

A configured Droid4 Leste installation is unique to the device that it was calibrated on. Particularly the wlan firmware calibration will be incorrect if an existing Leste installation is transferred to a different device.

The wifi calibration script requires a system set to stock settings to calibrate-from. It cannot just be re-run on an already calibrated system.

To recalibrate the wifi firmware on a different Droid4, you must reset the FEM parameters to stock settings on the new device, then recalibrate.
If you can get the device online (usb networking or moving close to the WLAN AP) this can be done with.
apt reinstall firmware-ti-connectivity
If not, you can download the firmware-ti-connectivity_[version]_all.deb on another Leste device
apt download firmware-ti-connectivity
Then copy the .deb to your new device and install that (as root) with
dpkg -i firmware-ti-connectivity_[version]_all.deb
Then (as root) re-calibrate the wifi chip by running
/usr/bin/maserati-calibrate
Then reboot.

Pavel: /* Devel repository */

= Devel repository =

As of 11/2021, this is bleeding edge development. You need to switch to devel repositories which may break your system. To do that append line <pre>deb https://maedevu.maemo.org/leste beowulf-devel main contrib non-free</pre> into /etc/apt/sources.list and run sudo apt update.

= Phone calls =

Voice calls should be working, or close to working, on Motorola Droid 4. Ofonod is handling the modem, and it is configured and running by default. Modem is not enabled by default. enable-modem and online-modem scripts from ofono/test can be used to put modem online. sphone can be used as an UI to place and receive calls, it can be installed using sudo apt install sphone.

== Installation ==

Hardware requirements:

* Droid4 with fully charged battery
* MicroUSB cable
* MicroSD card

Software requirements:
* Host Linux or Windows system
* Android Tools: fastboot
* Flashing tools:
** XZ Utils and coreutils for Linux
** Etcher[https://github.com/balena-io/etcher] for Windows

Download from https://maedevu.maemo.org/images/droid4/

# VRZ_XT894_9.8.2O-72_VZW-18-8_CFC.xml.zip
# flash-droid-4-fw.sh
# Latest maemo-leste-1.0-armhf-droid4-*.img.xz

Download from https://github.com/tmlind/droid4-kexecboot.git

# utags-mmcblk1p13.bin
# droid4-kexecboot.img

Check what kernel version your Android OS runs.
For this go to Settings -> About phone. Slide to the bottom, where you can see "Kernel version".
If you have at least 3.0.8, you may skip "Updating Android" step below.

Installation:

# Create a working directory with above mentioned files in it
# unzip VRZ_XT894_9.8.2O-72_VZW-18-8_CFC.xml.zip
# Power off Droid4 and connect it to the host machine with MicroUSB cable
# Start the device in fastboot mode. For this press power button and bottom volume key simultaneously and release them after a second.

=== Updating Android ===

This will reinstall the Android OS on your device, deleting all user data. Do a backup, if you want to save something. When everything is ready, go to the working directory mentioned above and run:
<pre>
pushd VRZ_XT894_9.8.2O-72_VZW-18-8_CFC.xml
sudo bash ../flash-droid-4-fw.sh
popd
</pre>

=== Setting up kexecboot ===

Now, assuming you are in the working directory, install kexecboot:

<pre>
sudo fastboot flash mbm VRZ_XT894_9.8.2O-72_VZW-18-8_CFC.xml/allow-mbmloader-flashing-mbm.bin
sudo fastboot reboot-bootloader
sudo fastboot flash bpsw droid4-kexecboot.img
sudo fastboot flash utags utags-mmcblk1p13.bin
sudo fastboot reboot
</pre>

If you did "Updating Android" the device should run the firstboot steps.
If you didn't, the device should reboot and show kexecboot menu for a few seconds before it boots to Android.

=== Install Maemo Leste to the sdcard ===

Now, flash the Maemo Leste image to your sdcard:

On Linux:
<pre>
xzcat maemo-leste-1.0-armhf-droid4-20190227.img.xz | sudo dd status=progress bs=1M of=/dev/MICROSDCARD-DEVICE
sync
</pre>

On Windows: Use Etcher

Wait for sync to complete and insert MicroSD card into Droid4. Reboot the device and select Maemo Leste from the kexecboot menu.

You should now see Maemo Leste booting up, and it will show you hildon-desktop after a minute.

== Updating ==

Normally you can just apt update && apt dist-upgrade to update to the latest version. If for some reason this fails:

* Poweroff device, grab the SD card
* Backup any important files
* Grab the latest image from https://phoenix.maemo.org/view/Images/
* Write it as before : xzcat maemo-leste-1.0-armhf-droid4-20190227.img.xz | sudo dd status=progress bs=1M of=/dev/MICROSDCARD-DEVICE

== Notes ==

The battery in Droid4 is not easily removable. If you got the device stuck, use this combo: power button + bottom volume key. You should hold them for about 7 seconds. Droid4 will then reboot.

If Maemo is still running, you can also hold just the power button for ~10 seconds, and the device will run poweroff.

Some users reported that Bluetooth kernel module interfere badly with the WiFi driver on their devices.
Blacklisting the module may help if you have such problems:
echo "blacklist hci_uart" >> /etc/modprobe.d/blacklist.conf

Also see [[Motorola_Droid_4/Modem]] [[Motorola_Droid_4/PowerVR]]

Also see: http://elektranox.org/droid4/ and http://muru.com/linux/d4/

The keyboard layout is extended to provide more standard keys.
[[File:Maemo-leste-droid4-kbd-2021-07.png|center|620px|thumb|maemo-leste droid4 keyboard]]
Key mapping can be tested with the 'xev' program.

== Serial Cable ==

As explained at http://muru.com/linux/d4 , the Droid 4 exposes a serial console on the USB port. You can construct the required cable easily by following the instructions there. If you have old Nokia CA-42 or DKU-5 cables, then you can use them with the Droid 4, using instructions at https://jethomson.wordpress.com/2010/02/21/diy-usb-to-serial-cable-for-3usd/

While using the serial cable, if you lose the connection, the following may help:

<pre>
18:43 < tmlind> sicelo: hmm the uart debug cable multiplexing still has issues, if the uart disappears during boot it should come back with
the console login propt later
18:45 < tmlind> try plugging in a pc usb cable then back to uart cable in case that might help
</pre>

== Bluetooth ==

Needs firmware - install latest firmware-ti-connectivity - See also https://github.com/maemo-leste/bugtracker/issues/290. Due to interference with WiFi, load driver manually, AFTER wifi module loaded

== Stuff to try ==

==== Blinkenlights ====
Adding this in rc.local above the ''exit 0'' gets you some blinkenlights to watschen und relaxen.
echo cpu > /sys/class/leds/lm3532::kbd_backlight/trigger # gets you a cpu activity monitor on the keyboard backlight
echo mmc0 > /sys/class/leds/shift-key-light/trigger # gets you a 'hdd led' of the SD card on the capslock light

==== Wifi ====

The WL1285C Wifi chip in the droid 4 has no onboard nvmem to save its calibration parameters or its MAC address. Instead it gets these parameters from a configuration file provided by the kernel. By default a generic file is provided but for optimal range and a correct persistent MAC address a calibration procedure must be performed.

Install necessary tools:
<pre>
apt-get install ti-utils-wilink6 droid4-wlanconfig
</pre>
Run calibration:
<pre>
sudo maserati-calibrate
</pre>

==== Phone Call ====

These can be used to talk to the modem manually... But we really should have ofono and sphone GUI doing that job. [[Status/Phone]] mentions current status. Make sure there is a SIM in the phone.

Run this:

Read modem output:
<pre>
cat /dev/motmdm1 &
</pre>

Online modem:
<pre>
printf "AT+CFUN=1\r" > /dev/motmdm1
</pre>

Connect to network:
<pre>
printf "AT+COPS=1\r" > /dev/motmdm1
</pre>

Print connected network:
</pre>
printf "AT+COPS?\r" > /dev/motmdm1

Turn off signal reporting:
<pre>
# printf "AT+SCRN=0\r" > /dev/motmdm1
</pre>

Dial a number:
<pre>
printf "ATD+1234567890\r" > /dev/motmdm1
</pre>

Hang up:
<pre>
printf "ATH\r" > /dev/motmdm1
</pre>

Answer incoming call:
<pre>
printf "ATA\r" > /dev/motmdm1
</pre>

Audio wise, in a pulsaudio of you choice switch to the make a phone call profile, and set the output device as desired.

==== 3G Internet ====

Using qmicli:

qmicli -d /dev/cdc-wdm0 --wds-follow-network --wds-start-network=apn=internet.t-mobile.cz
route del default
sudo ifconfig wwan0 up
dhclient wwan0

Alternatively if updated to devel icd2 and the maemo gui should allow 3g data connection, if the sim is unlocked and the relevant packages are installed.

==== GPS ====
<pre>
modprobe gnss-motmdm and point gpsd to use /dev/gnss0
</pre>

22:30 < tmlind> hmm there's a probably kernel gnss bug for gsp access fyi, you can currently only open one connection before you have to restart gpsd :)

Can try to <pre>
mkfifo /tmp/gps
cat /dev/gnss0 > /tmp/gps
Then point gpsd to use /tmp/gps
</pre>

==== USSD ====

<pre>
22:45 < tmlind> fyi, here's how to send USSD to query balance for example: printf "AT+CUSD=1,#999#,0\r" > /dev/motmdm1
22:47 < tmlind> fyi, for parsing incoming USSD, this web interface works if set to utf-8:
https://www.mobilefish.com/services/latin_utf_base64_to_hex/latin_utf_base64_to_hex.php#text_hex_output
</pre>

==== HDMI ====
Move output to external 1080p monitor. Disabling DSI-1 output gets xorg pointer displayed on HDMI, for use with a mouse or barrier.
<pre>
xrandr --output HDMI-1 --mode 1920x1080 --output DSI-1 --off
</pre>
Return to internal touchscreen display.
<pre>
xrandr --output DSI-1 --auto --rotate right --output HDMI-1 --off

==== Keyboard / Mouse sharing with PC ====
To use droid4 while working at desktop it can be convenient to share mouse and keyboard of the host pc with droid4.
<pre>
[https://github.com/debauchee/barrier Barrier software-KVM switch]
</pre>
Developers and testers may wish to disable the googley bits before compiling.

==== BT Audio headset ====

sudo apt install pulseaudio-module-bluetooth blueman bluez
sudo modprobe hci_uart
pactl load-module module-bluetooth-discover
blueman-manager

Pair & trust your device in blueman, connect audiosink. You can close blueman now. The quality seems a bit better in 'offline mode'.

== Using a configured Leste sdcard in a different Droid4 ==

A configured Droid4 Leste installation is unique to the device that it was calibrated on. Particularly the wlan firmware calibration will be incorrect if an existing Leste installation is transferred to a different device.

The wifi calibration script requires a system set to stock settings to calibrate-from. It cannot just be re-run on an already calibrated system.

To recalibrate the wifi firmware on a different Droid4, you must reset the FEM parameters to stock settings on the new device, then recalibrate.
If you can get the device online (usb networking or moving close to the WLAN AP) this can be done with.
apt reinstall firmware-ti-connectivity
If not, you can download the firmware-ti-connectivity_[version]_all.deb on another Leste device
apt download firmware-ti-connectivity
Then copy the .deb to your new device and install that (as root) with
dpkg -i firmware-ti-connectivity_[version]_all.deb
Then (as root) re-calibrate the wifi chip by running
/usr/bin/maserati-calibrate
Then reboot.

Generic virtual machine target. This is particularly useful when doing development and testing.

== Installation ==

https://maedevu.maemo.org/images/virtual-machines/

There are three different types of images: VirtualBox (.box), QEMU (.qcow2, .vdi) and Vagrant. The VirtualBox image may be converted to a VMware VMDK image which has been reported to perform better and have good hardware acceleration.
Converting the qcow2 image to raw allows it to be used on real hardware.

=== VirtualBox ===

The image is archived, we need to unpack it first:
mkdir -p ~/VirtualBox\ VMs/maemo-leste
tar xzf maemo-leste-1.0-amd64-virtual-20180425.box -C ~/VirtualBox\ VMs/maemo-leste

Start VirtualBox, File -> Import Appliance... -> VirtualBox VMs/maemo-leste/box.ovf -> Import. The virtual machine name is devuan-ascii-prevagrant.

Unpacked files may now be removed:
rm -r ~/VirtualBox\ VMs/maemo-leste

As the memory of virtual machine is limited to 256M some applications will have troubles with it. One example is aptitude. To increase the memory limit you should add the swap partion or change the memory settings in the VirtualBox menu.

For newer versions, .box file is not available. You can still use virtualbox, select "Debian (64-bit)" and 1024MB RAM.

=== QEMU ===

To run image on qemu, you can do:

xz -d maemo-leste-1.0-amd64-virtual-20180425.vdi.xz

qemu-system-x86_64 maemo-leste-1.0-amd64-virtual-20180425.vdi

Note that unaccelerated qemu is too slow to run maemo leste in an useful way.

=== Real hardware ===

xz -d maemo-leste-1.0-amd64-virtual-20180425.qcow2.xz
qemu-img convert -f qcow2 -O raw maemo-leste-1.0-amd64-virtual-20180425.qcow2 delme.img

Now you can copy delme.img ... to a spare harddrive? I tried with USB stick and could not get that to work.

== Initial configuration ==

On the first run you may want to generate ssh host keys and set the timezone. To do so open the "X Terminal" application and run:
sudo su -
dpkg-reconfigure openssh-server
dpkg-reconfigure tzdata

Make the system up-to-date:
apt-get update
apt-get upgrade
apt-get install linux-image-amd64
reboot

To get networking to work (at least in virtualbox), launch a shell and do
sudo ifconfig eth0 up
sudo dhclient eth0

== Installation ==

''' [https://github.com/stargo/android_packages_apps_Safestrap/releases/tag/v3.75 SafeStrap] + [https://github.com/tmlind/ddroid ddroid] from eMMC or SD card '''

PostmarketOS has some information how to install safestrap: [https://wiki.postmarketos.org/wiki/Motorola_Droid_4_(motorola-maserati) in wiki]

(This is the boot method currently being used but we'll probably replace this with [https://github.com/tmlind/droid4-kexecboot droid4-kexecboot] to aid kernel updates via deb package)

Flashing the zip file is quite confusing / tricky:

Boot options, select slot with Leste, Activate.

In main menu: Install, scroll down to select ddroid-....zip file, swipe to confirm flash. You will get error, including "ApplyParsePerms, set_metadata_recursive, Error executing updater binary, Unable to mount." Red "failed" will appear. These are normal. Proceed by selecting "Reboot System", you'll get one more warning that system is not installed, swipe to confirm reboot.

Red motorola logo will appear, press search button to continue boot, phone vibrates, then vibrates again, then green led comes on. After about a minute, console appears, then disappears and X comes to life.
