== Installation ==

Hardware requirements:

* Droid Bionic with fully charged battery
* MicroUSB cable
* MicroSD card

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

Download from https://phoenix.maemo.org/view/Images/job/leste-image-bionic/

# Latest maemo-leste-1.0-armhf-bionic-*.img.xz

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

# droid4-kexecboot.img

Download or clone https://github.com/IMbackK/bionic-clown-boot

Follow the instructions in bionic-clown-boot's readme to install kexecboot on your device.

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>

Wait for sync to complete and insert MicroSD card into The Bionic. 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 ==

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

* Poweroff device, grab the SD card
* Backup any important files
* Grab latest image from https://phoenix.maemo.org/view/Images/job/leste-image-bionic/
* 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 ==

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/

== Serial Cable ==

As explained at http://muru.com/linux/d4 , the Droid 4 and Bionic both expose 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 Bionic, using instructions at https://jethomson.wordpress.com/2010/02/21/diy-usb-to-serial-cable-for-3usd/

== 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

== Unlocking the modem for usage in Europe ==

Tony suggested these values, Wizzup confirmed it to work on his Bionic in Europe/Amsterdam.

<pre>
apt install build-essential
git clone https://github.com/tmlind/tcmdrw
cd tcmdrw
make
./tcmdrw 1877=8703E80400000200
./tcmdrw 6850=05
</pre>

Tony also writes:

<pre>
22:34 < tmlind> hmm so i had to do this for 3g gain: tcmdrw 1143=aaff0000, got that value from xt910 firmware i think, otherwise 3g signal was weak
22:43 < tmlind> Wizzup: great, the 1143 setting is for 1900 frequency only to get decent signal on t-mo in the us
</pre>

== Stuff to try ==

==== Wifi ====

The WL1271 Wifi chip in the Bionic 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>

==== 3G Internet ====
<pre>
22:12 < pave1> qmicli -d /dev/cdc-wdm0 --wds-follow-network --wds-start-network=apn=internet.t-mobile.cz
22:12 < pave1> route del default
22:12 < pave1> sudo ifconfig wwan0 up
22:12 < pave1> dhclient wwan0
</pre>

==== 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
