Installation
Hardware requirements:
- A Razr or Droid Razr or Droid Razr MAXX with fully charged battery
- MicroUSB cable
- MicroSD card
Software requirements:
- Host Linux or Windows system
- Android Tools: fastboot
- get allow-mbmloader-flashing-mbm.bin for your device (xt910 or xt912) from an android update zip
- Flashing tools:
- XZ Utils and coreutils for Linux
- Etcher[2] for Windows
Download from https://github.com/tmlind/droid4-kexecboot.git
- utags-xt910-16-mmcblk1p8-boots-mmcblk1p13-kexecboot.bin
- droid4-kexecboot.img
Installation:
- Create a working directory with above mentioned files in it
- Power off the Razr 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.
Setting up kexecboot
Now, assuming you are in the working directory, install kexecboot:
sudo fastboot flash mbm allow-mbmloader-flashing-mbm.bin sudo fastboot reboot-bootloader sudo fastboot flash bpsw droid4-kexecboot.img sudo fastboot flash utags utags-xt910-16-mmcblk1p8-boots-mmcblk1p13-kexecboot.bin sudo fastboot reboot
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:
xzcat maemo-leste-1.0-armhf-razr-$DATE.img.xz | sudo dd status=progress bs=1M of=/dev/MICROSDCARD-DEVICE sync
On Windows: Use Etcher
Wait for sync to complete and insert MicroSD card into the Razr. 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 Razr 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. Razr will then reboot.
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 Razr, 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 (hci_uart) manually, AFTER wifi module loaded
Using a bluetooth 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.
Additional Tips
Using a battery without temperature sensor
Modprobe the pmic driver as follows:
cpcap-battery ignore_temperature_probe=1
Flashing the boot logo
More info: https://github.com/xsetiadi/droid4-kexecboot/blob/master/LOGO
logos can be flashed via fastboot flash logo.bin logo.bin
HDMI
Move output to external 1080p monitor. Disabling DSI-1 output gets xorg pointer displayed on HDMI, for use with a mouse or barrier.
xrandr --output HDMI-1 --mode 1920x1080 --output DSI-1 --off
Return to internal touchscreen display.
xrandr --output DSI-1 --auto --rotate right --output HDMI-1 --off
Using a configured Leste sdcard in a different Razr
A configured Razr Leste installation will have a unique wlan firmware calibration. 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 Razr, 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.
