How to enter flash mode

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

How to enter recovery mode

Press and hold Volume Up + Power simultaneously.

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.
