Installation
First, install pmbootstrap.
Setup device to be used:
$ pmbootstrap init
...
Vendor [samsung]: samsung <- enter this
Device codename [s3ve3g]: s3ve3g <- enter this
User interface [weston]: <- choose any UI by your preference
...
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!
Booting from SD card also works:
$ pmbootstrap install --sdcard=/dev/sdg
Remember to change device /dev/sd* to your card reader
$ pmbootstrap flasher flash_kernel
Additional info
Phone is booting fine. When in charging mode it shows postmarketOS charging error splash screen.
