How to enter flash mode

When the phone is powered off, hold the Power, Home and Volume Down buttons to boot into download mode. A turquoise colored screen will appear, asking for confirmation. Press Volume Up to confirm. Your device is ready for flashing via a front-end such as Odin or Heimdall.

To boot into recovery, hold the Power, Home and Volume Down buttons.


Notice Download mode performs some checks with the provided images before flashing it for partitions except BOOT. The images generated by pmbootstrap do not pass those checks, and thus it isn't possible to flash the rootfs using download mode.

Installation

Prerequisites

Make sure your phone:

  • Has its bootloader unlocked.
  • Has a custom recovery installed (such as TWRP)

Preparation

Choose the following in the pmbootstrap init wizard:

Vendor: samsung
Device codename: j7y17lte
User interface: xfce4

xfce4 is tested and works out of the box. Other UIs are not guaranteed to work.

gnome-mobile comes with wayland as its dependency. Since wayland doesn't run in downstream kernels, xorg needs to be installed.

Extra packages: xorg-server

To proceed with the installation run:

$ pmbootstrap install --android-recovery-zip

This will begin installing pmbootstrap prepare a recovery zip file. By default, the rootfs is flashed in the SYSTEM partition of the device.

In order to change the default partition (let's say, the USERDATA partition), append --recovery-install-partition=USERDATA to the above command.

After the installation process is completed, get your phone booted into recovery, and enable sideloading via adb. Then run:

$ pmbootstrap flasher --method=adb sideload

The recovery zip gets flashed to your device. Reboot to system when it's done.
