What works
- Installation to sdcard (
pmbootstrap install --sdcard=/dev/mmcblk...
) - Installation to device memory (partial)
- Touchscreen
- Weston (only on SD card)
- XWayland

What does not work
- The rest (bluetooth, making calls, ...)
- Auto resizing partitions during installation to device memory (probably)
How to enter flash mode
- Connect a USB cable
- Make sure, the device is powered off
- Hold power + Home + volume down
- When prompted, release all buttons and press volume up
Installation
Flashing to device memory is close to being possible using drebrez's netcat method (#456), but currently DOES NOT APPEAR TO WORK. The following steps may have functioned at one point, but do not seem to at present.
Init pmbootstrap. Make sure to choose none for the user interface instead of weston because weston makes the image just a little bit too large for the unresized partition.
$ ./pmbootstrap.py init
Start the build process
$ ./pmbootstrap.py install
Flash postmarketOS to the device:
https://github.com/postmarketOS/pmbootstrap/issues/456
For the d710, on step 5 use /dev/mmcblk0p11 as the install partition.
On step 8, use
pv /home/pmos/rootfs/samsung-i9100.img | nc 172.16.42.1 60000
instead.

- Build image (on your computer)
-- Install pmboostrap
$ git clone https://github.com/postmarketOS/pmbootstrap.git
-- Change working directory to the pmboostrap
$ cd pmbootstrap/
-- Configure
$ ./pmbootstrap.py init [18:27:09] Device [samsung-i9100]: samsung-i9100 [18:27:45] User interface [weston]: weston [18:28:05] Work path [/home/<USER>/.local/var/pmbootstrap]: [18:28:29] Jobs [5]: [18:28:46] Timestamp based rebuilds (y/n) [y]: [18:29:05] Extra packages [none]:
-- Prepare the installation
$ ./pmbootstrap.py install
- Flash to phone memory - This will replace (break) your current phone system! The description is using the alternative flash method because there it did not work for me with heimdall - https://github.com/Benjamin-Dobell/Heimdall/issues/418
-- Set phone to ODIN mode
1. Turn off phone 2. Connect USB cable 3. Hold VOLUME_DOWN + HOME + POWER until you get Warning!! screen 4. Push VOLUME_UP to continue to ODIN mode screen
-- Set image for NETCAT flash method
$ ./pmbootstrap.py initfs hook_add usb-shell
-- Flash Kernel and Recovery (phone will reboot to screen "boot partition not found")
$ ./pmbootstrap.py flasher flash_kernel
-- Check USB network connection to phone
ping 172.16.42.1
(if it does not ping, try replugging usb cable few times)
-- Connect to phone with telnet
$ telnet 172.16.42.1 24
-- Start netcat to listen for image (on the phone) /dev/mmcblk0p9 should be FACTORYFS partition you check by running fdisk -l /dev/mmcblk0
/ # nc -v -l -p 60000 > /dev/mmcblk0p9
-- Switch to pmboostrap chroot (on the computer in other terminal)
$ ./pmbootstrap.py chroot --suffix native
-- Install pv (in the chroot)
/ # apk add pv
-- Send image from computer to netcat (on the computer)
/ # pv /home/pmos/rootfs/samsung-i9100.img | nc 172.16.42.1 60000
-- Close both nc with CTRL+C when transfer finishes and reboot the phone with power button
-- Telnet to phone to enter password
$ telnet 172.16.42.1
-- Follow further instructions from telnet
Boot process
We're using the heimdall-isorec
flash method, see deviceinfo_flash_methods for more information.

Wifi
- Create conf for wpa_supplicant
$ wpa_passphrase "SSID" "password" > wifi
Note : If you are connecting to a hidden wireless network, make sure to add line "scan_ssid=1" after the ssid line in your generated conf file
- Connect to wifi AP
$ sudo wpa_supplicant -i wlan0 -c wifi &
- Get ip address from dhcp server (in another terminal)
$ sudo udhcpc -i wlan0
To set wifi connection to start automatically on boot, please refer here wifi
ofono
Best way seems to get Samsung IPC modem support from the patchset https://lists.ofono.org/pipermail/ofono/2012-September/013766.html (but it was not accepted) and does not build https://github.com/tssk/pmbootstrap/commits/device-samsung-i9100_modem . I would appreciate help from someone that understands C.
Second idea was to build Andoird RIL + Samsung RIL and get ofono working with ofono-ril support - https://redmine.replicant.us/projects/replicant/wiki/Samsung-RIL .

Setting the hardware clock
If you have already setup chrony and if your hardware clock doesn't have the time set you can set it with,
localhost:~# hwclock -w # Write the current system time to the hardware clock
Setting the display brightness
To adjust display brightness write a value between 0-255 to file given below,
localhost:~# echo 0 > /sys/class/backlight/panel/brightness #set the display to its lowest brightness
localhost:~# echo 255 > /sys/class/backlight/panel/brightness #set the display to maximum brightness
Reading Accelerometer sensor
Accelerometer sensor data can read from following file
localhost:~$ cat /sys/class/accelerometer/accelerometer/acc_file
