=== Preparing for install ===
== Installation ==
First, [[Installing_pmbootstrap|install pmbootstrap]].


First, [https://dl.twrp.me/kminilte/ download the TWRP recovery ROM]. You'll need both the <code>.img.tar</code> and the <code>.img</code> file. First, extract the tar file to obtain <code>recovery.img</code>. Then, put your phone in flash mode and flash using Heimdall:
Setup device to be used:
<source lang="shell-session">
$ pmbootstrap init
Channel [edge]:
Vendor [samsung]: samsung      <- enter this
Device codename [i9100]: kminilte  <- enter this
...
</source>


<pre>$ heimdall flash --RECOVERY recovery.img --BOOT twrp-3.2.3-0-kminilte.img</pre>
Build the rootfs image:
Now you should be able to connect to the device using <code>adb</code>.
<source lang="shell-session">
$ pmbootstrap install
</source>


Note: Be aware that the stock Android ROM reflashes stock recovery upon boot, wiping TWRP out if you let it start booting.
Then in order to flash it put your device in download mode, and plug it in USB. Then do:


=== Installing system ===
<source lang="shell-session">
$ pmbootstrap flasher flash_rootfs


Follow [https://wiki.postmarketos.org/wiki/Installation_guide the android-recovery-zip steps], using <code>samsung-kminilte</code> when the init commands asks. Heimdall is currently unable to flash the SYSTEM partition, and adb sideload method seems broken, so you will have to do <code>pmbootstrap export</code> after generating the recovery and pushing it to the phone while it is booted in TWRP via <code>adb push /tmp/postmarketOS-export/pmos-samsung-kminilte.zip /sdcard/</code>.
Hold "Volume down" + "Home" buttons at the end of the process,
so that when phone reboots put it in flashing mode again


Then just flash it via recovery as you would a normal android ROM. Currently on Samsung devices you may get an error about unmounting .log files, it seems to work on second try but due to another issue you have to make sure SYSTEM is unmounted in TWRP before attempting to do so.
$ pmbootstrap flasher flash_kernel


If you get an error <code>lddtree not found</code>, simply run <code>apk add lddtree</code> in the chroot environment and try again.
This time, don't hold any button, let it reboot to Linux!
 
</source>
If you get the following errors:
 
<pre>device-mapper: reload ioctl on  failed: No such file or directory
Failed to setup dm-crypt key mapping for device /dev/block/mmcblk0p18.
Check that kernel supports aes-xts-plain64 cipher (check syslog for more info).</pre>
You can try to reinstall with a different cipher, by editing <code>install_options</code> and changing the <code>CIPHER</code> line to <code>CIPHER=&quot;aes-cbc-plain64&quot;</code>, re-zipping and using <code>adb sideload</code> again.
 
=== Installing kernel ===
 
This can be done via <code>./pmbootstrap.py flasher flash_kernel</code>, but if you followed the recovery ROM steps then you don't need to do this.

How to enter flash mode

Press and hold Volume Down + Home + Power simultaneously. Then click Volume Up to confirm.

How to enter recovery mode

Press and hold Volume Up + Home + Power simultaneously.

Problems

  • udevadm trigger causes a complete system freeze and eventual reboot. If you comment out that line in start_weston.sh and replace it by udevadm trigger --attr-match=name=sec_touchscreen, the touch screen should work.

Installation

First, install pmbootstrap.

Setup device to be used:

$ pmbootstrap init
Channel [edge]:
Vendor [samsung]: samsung       <- enter this
Device codename [i9100]: kminilte   <- enter this
...

Build the rootfs image:

$ pmbootstrap install

Then in order to flash it put your device in download mode, and plug it in USB. Then do:

$ pmbootstrap flasher flash_rootfs

 Hold "Volume down" + "Home" buttons at the end of the process,
 so that when phone reboots put it in flashing mode again 

$ pmbootstrap flasher flash_kernel

 This time, don't hold any button, let it reboot to Linux!

It should boot, and show the Samsung splash screen. After that you should be able to setup and connect via SSH

Getting Wifi to work

Wifi requires firmware blobs to be installed:

 apk add firmware-samsung-kminilte


After installation, either reboot the device, or:

  1. start "deferred-initcalls" service
  2. restart networkmanager and / or wpa_supplicant and / or whatever you want to do with networking

When using networkmanager, you should now be able to connect to a network:

 nmtui

Troubleshooting Wifi

  • Interface wlan0 does not exist
  • using wlan0 or p2p0 fails with "Operation not permitted"
    • Check dmesg for messages containing "dhdsdio_download_firmware", to see if there was an error loading the firmware

What works

  • Booting off a microSD card
  • Display
  • Touchscreen
  • USB Networking
  • Full disk encryption
  • Proximity sensor
  • Light sensor
  • Heart rate sensor
  • Magnetic sensor
    • Chip: ALPS HSCDTD0008A (Datasheet)
    • Attached via: I2C, address 0x0c
    • Driver: hscd_i2c
  • Audio jack events
  • Physical buttons
    • Driver: gpio-keys
    • Device node: /dev/input/event8
      • KEY_HOMEPAGE: Home button
      • KEY_POWER: Power button
      • KEY_VOLUMEUP: Volume up button
      • KEY_VOLUMEDOWN: Volume down button
    • Use triggerhappy to configure what the buttons do
    • If you are running elogind, make sure to prevent it from handling the power button, by setting HandlePowerKeyIgnore in logind.conf
  • Touch keys
    • Attached via: I2C, address 0x20
    • Driver: i2c-gpio
    • Device node: /dev/input/event1
      • KEY_BACK Back button (right of the home button)
      • 254 (name neither listed by libinput, nor linux/input.h) Other button (left of the home button)
    • The left button cannot be used for triggerhappy right now, since it doesn't support configuring numeric key codes
  • Notification LED
    • Chip: Samsung KTD 2026
    • Attached via: I2C, address 0x30
    • Driver: ktd2026
    • This is an RGB LED. The red, green and blue channels can be controlled individually though led_r, led_g and led_b in /sys/class/leds/$led. Some examples:
      • full brightness red: echo 48 > /sys/class/leds/led_r/brightness (check max_brightness to make sure this is correct)
      • half brightness red: echo 24 > /sys/class/leds/led_r/brightness
      • blink green: echo 1 > /sys/class/leds/led_g/blink (set delay_{on,off} afterwards to control timing)
  • Vibration motor
  • Gyroscope
  • Wifi
  • Flashlight
    • Write mode "Torch" / "Off" to /sys/class/flashlight/rt-flash-led/mode to turn the light on and off
    • Change brightness by writing a value from 0 to 15 to /sys/class/flashlight/rt-flash-led/torch_brightness
    • See pmaports!1150 for details
