Samsung Galaxy SIII LTE (samsung-i9305)
So far, what works for samsung-i9305 (Galaxy SIII LTE version) also works for the samsung-i9300 (Galaxy SIII international GSM version without LTE). (Neither of these SIII models should be confused with the North American SIII models, which require OS builds.)
How to enter flash mode
- Hold power + Home + volume down
- When prompted, release all buttons and press volume up
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
At this point you can follow the general installation guide.
Installation to the system is not yet supported for the device, so make sure to install postmarketOS to the sdcard. Also be sure to disable FDE (
--no-fde) as osk-sdl is not yet supported for this device, and enabling it would require you to telnet into the device to unlock it.
To get the wifi working, you'll need to modify the wpa_supplicant confg
# If this is not done, wpa_supplicant launches itself with -ip2p0 $ echo 'wpa_supplicant_args="-iwlan0 -Dwext"' | sudo tee /etc/conf.d/wpa_supplicant $ sudo wpa_passphrase $YOUR_SSID > /etc/wpa_supplicant/wpa_supplicant.conf $ /etc/init.d/wpa_supplicant restartWrite the following file to
auto lo iface lo inet loopback auto wlan0 iface wlan0 inet dhcp
Restart the network to verify it's working
$ /etc/init.d/networking restart
Set it to start on boot
$ sudo rc-update add wpa_supplicant boot $ sudo rc-update add networking default
Reboot and you should be connected on boot.
The mainline kernel now support has some support for the Samsung Galaxy SIII LTE (i9305):
Upstream dts: exynos4412-i9305.dts
Upstream status: Midas on Mainline.
Note that a patch is required to make it work with the stock samsung bootloader.
Replicant is also interested in mainlining this device and replacing the bootloader with u-boot and would like to collaborate with us .
