See Installation guide. Flashing can be done using Fastboot (preferred) or Heimdall.

From a prebuilt image

  1. Download an image from https://images.postmarketos.org/bpo/edge/samsung-manta/
  2. Uncompress files, e.g.:
    • xz -d 20240222-1756-postmarketOS-edge-phosh-22.3-samsung-manta-boot.img.xz
    • xz -d 20240222-1756-postmarketOS-edge-phosh-22.3-samsung-manta.img.xz
  3. Then flash files with fastboot:
    • fastboot flash boot 20240222-1756-postmarketOS-edge-phosh-22.3-samsung-manta-boot.img
    • fastboot flash userdata -S 1G 20240222-1756-postmarketOS-edge-phosh-22.3-samsung-manta.img
  4. Reboot

From pmbootstrap

fastboot

pmbootstrap flasher flash_kernel
pmbootstrap flasher flash_rootfs

If rootfs partition is bigger than 1 GiB:

pmbootstrap export
cd /tmp/postmarketOS-export
fastboot flash boot boot.img
fastboot flash -S 1G userdata samsung-manta.img

heimdall

pmbootstrap flasher --method heimdall-bootimg flash_kernel --partition boot
pmbootstrap flasher --method heimdall-bootimg flash_rootfs --partition userdata

Main board UART

To simplify getting logs when doing development, it can be useful to connect to UART directly on the main board. UART can be found at a 12 pin connector close to edge of board. The same connector is used for many of samsung's devices, but pinout varies, see Serial_debugging#Main_board_UART_on_exynos_devices. Pad number 1 where the tiny triangle is pointing, and TX (from manta's perspective) is then pad 10, and RX pad 12. The device uses 1.8 V signal strength.
