Basic info

So far, what works for samsung-i9305 (Galaxy SIII LTE version) also works for the samsung-i9300 (Galaxy SIII international GSM version without LTE) and samsung-shv-e210s (a Korean variant). (None of these SIII models should be confused with the North American SIII models, which require OS builds.)

Code name is MIDAS. Search for midas-mainline to find more info.

How to enter flash mode

  • Hold power + Home + volume down
  • When prompted, release all buttons and press volume up

Installation

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
# Ready the build
pmbootstrap init # (weston or xfce4 should do)

# Install rootfs to Micro SD Card
pmbootstrap install --sdcard=/dev/mmcblk0/1/2/3 # (will depend on where your Micro SD Card is mounted)

# Put the i9305 / i9300 into odin mode with the steps above and flash the kernel (to boot from the Micro SD Card)
pmbootstrap flasher flash_kernel # (in odin mode)

# and it should reboot automatically

Installing with downstream kernel

#FIRST PMBOOTSTRAP INSTALL
mkdir ~/code
cd ~/code
git clone https://gitlab.com/postmarketOS/pmbootstrap.git

#CONFIG PMBOOTSTRAP
alias pmbootstrap=~/code/pmbootstrap/pmbootstrap.py
pmbootstrap init
#work path default

#FOR DEBUGGING (NOT REQUIRED)
pmbootstrap initfs hook_add debug-shell
#Check log with 'tail -f ~/.local/var/pmbootstrap/log.txt'

#CREATE RECOVERY ZIP (for flashing with TWRP)
pmbootstrap install --android-recovery-zip

#COPY ON SDCARD
cp ~/.local/var/pmbootstrap/chroot_buildroot_armhf/var/lib/postmarketos-android-recovery-installer/pmos-samsung-i9305.zip /media/computer/sdcard/
#Insert sdcard in phone
#Reboot on recovery with up+home+power
#Install from zip
#Reboot

#IF BOOT STANDBY (DEBUG)
#Connect with USB cable

Wifi

To get the wifi working, you'll need to modify the wpa_supplicant configuration. If this is not done, wpa_supplicant starts with -ip2p0 which is not supported on our device.

 $ echo 'wpa_supplicant_args="-Dwext"' | sudo tee /etc/conf.d/wpa_supplicant

You can use either Network manager or networking and wpa_supplicant. Network manager is recommend in most cases as it handles reconnection.

Network Manager

Ensure the networkmanger service is running

 $ sudo rc-status | grep 'networkmanager'

if it not visible, try to start the service:

 $ sudo rc-service networkmanager start

Search for available WiFi networks and connect to network

 $ sudo nmcli device wifi list ifname wlan0
 $ sudo nmcli --ask dev wifi connect SSID

Reboot and you should be connected.

Networking and wpa_supplicant

You will need to manually configure the interfaces by creating

/etc/network/interfaces

e.g.,

 $ sudo vi /etc/network/interfaces
  auto lo
  iface lo inet loopback
  auto wlan0
  iface wlan0 inet dhcp
  

Save changes and add networking to start with system

$ sudo rc-update add networking

Add WiFi network information

$ wpa_passphrase YOUR_SSID YOUR_PASSPHRASE | sudo tee /etc/wpa_supplicant/wpa_supplicant.conf

Restart services

$ sudo rc-service wpa_supplicant restart
$ sudo rc-service networking start

Mainline Kernel

Thanks in large part to the Midas on Mainline work that was done a few years ago, we now have initial mainline support for this device. The pmOS patch that added initial support is here.

The pmports repo for this device's linux-postmarketos-exynos4 mainline kernel is here.

@pmOS_devices announcement from Nov 11, 2020: Shttps://twitter.com/pmOS_devices/status/1326525105162293249

Upstream dts: exynos4412-i9305.dts

Blog announcement: https://postmarketos.org/blog/2020/11/06/postmarketOS-in-2020-11-part-1/#mainline-all-the-phones-and-tablets

Upstream kernel support matrix: Midas on Mainline.

Note that a patch is required to make it work with the stock samsung bootloader and this is included in the pmports mainline repo above.

forkbomb from LineageOS got mainline u-boot running on this device and wrote about it in this blog post: [1]

Replicant has this device booting with mainline Linux and almost mainline U-Boot with only the need for a few patches on top and would like to collaborate with us [2]

The Qualcomm Gobi MDM9615 Modem seems to have mainline kernel support as well: [3]

The Replicant project is working on getting the i9300 modem working with a mainline kernel in a way that pmOS can also utilize: https://redmine.replicant.us/issues/1954 https://git.replicant.us/contrib/GNUtoo/kernel_replicant_linux/log/?h=replicant-11-i9300-modem

LTE modem support with the mainline kernel on Replicant is being done here: https://redmine.replicant.us/issues/2206 The Note II discussed here has the same or very similar modem as the i9305.

Replicant and LineageOS successfully got the Lima driver for Mesa working on Mali when using mainline linux: video success announcement linux-postmarketos-exynos4 now also has the same support.

Replicant currently supports this device in 6.0 and is doing a lot of research in order to get it running with a mainline kernel with a mainline bootloader for Replicant 11. More bootloader research is here.

xboot might be a completely free bootloader option. Looks to have zero proprietary blobs.

This might be depreciated now that linux-postmarketos-exynos4 has been released.
