How to enter flash mode

Press volume down + the power button to enter Download Mode. It is now possible to use Heimdall for flashing.

Installation

  1. git clone https://gitlab.com/postmarketOS/pmbootstrap.git && cd pmbootstrap
  2. ./pmbootstrap.py init
  3. ./pmbootstrap.py install --no-fde
  4. Put your S4 in Download Mode (Volume Down + Power) and connect it with USB
  5. ./pmbootstrap.py flasher flash_kernel
  6. ./pmbootstrap.py flasher flash_rootfs

Wifi

Once the device has been successfully initialized, enable it:

$ sudo ip link set wlan0 up

Configure wpa_supplicant (only necessary on encrypted networks):

$ sudo su -
# wpa_passphrase $YOUR_SSID > /etc/wpa_supplicant/wlan0.conf
<enter passphrase here and press Enter>
# exit

Connect to network using wpa_supplicant:

$ sudo wpa_supplicant -i wlan0 -c /etc/wpa_supplicant/wlan0.conf 

If your network uses DHCP, start the DHCP client:

$ sudo udhcpc -i wlan0
