LinageOS on Samsgung Galaxy S5e WiFi from scratch from Linux with heimdall

Compile a patched version of heimdall

cd /tmp
git clone https://github.com/Benjamin-Dobell/Heimdall.git
cd Heimdall
git fetch origin pull/478/head:pr478
git checkout pr478
mkdir build
cd build
cmake -DCMAKE_BUILD_TYPE=Release ..
make
  • The patched version of heimdall can be found in bin

Enable OEM unlock

  • Boot the device
  • In device info / software info tap 7 times on "Build number" - this will enable developer options
  • In developer options enable "OEM unlock" This option might not be available unless the device is connected to a wifi or mobile internet connection

Unlock the bootloader

  • power off the device
  • while pressing and holding Vol+ and Vol-, plug an USB cable (you might need to grow another hand to do so ^^)
  • A blue warning screen will appear with 3 options
    • Vol+: Continue
    • Vol+ long press: Device unlock mode
    • Vol-: Cancel
  • Use "Vol+ long press" to unlock the bootloader
  • On the next screen, confirm with "Vol+". This will unlock the boot loader and factory reset the device

Re-enable OEM unlock

  • After unlocking the bootloader, boot the device
  • Go through the android setup, connect the device to a wifi
  • Repeat the steps above to enable "OEM unlock"
  • In my case, "OEM onlock" was still enabled and grayed out. But be sure to have it checked.

Flash a modified version of vbmeta.img

  • power off the device
  • while pressing and holding Vol+ and Vol-, plug an USB cable
  • A blue warning screen will appear with the same 3 options as before
  • press "Vol+" to enter "download" mode
  • In the top left corner are some relevant information. Be sure that it correlates with the following, otherwise bad things will happen
    • FRP LOCK: Off
    • OEM Lock: OFF (U)
  • Download vbmeta.img from https://download.lineageos.org/devices/gts4lvwifi/builds
  • Using heimdal compiled in the initial step, now run ./bin/heimdall flash --VBMETA /tmp/vbmeta.img --verbose
  • After successfully flashing the image, the device reboots with a lot of warnings. It fails to boot into android and recommends a factory data reset
    • Follow the instructions to do the factory data reset
    • Android will now boot

Re-enable OEM unlock

  • After unlocking the bootloader, boot the device
  • Go through the android setup, connect the device to a wifi
  • Repeat the steps above to enable "OEM unlock"
  • In my case, "OEM onlock" was still enabled and grayed out. But be sure to have it checked.

Flash and boot recovery.img

  • Power off the device, hold Vol+ and Vol-, plug an USB device
  • On the blue screen press "Vol+" to enter "download" mode
  • Download recovery.img from https://download.lineageos.org/devices/gts4lvwifi/builds
  • Using heimdal compiled in the initial step, now run ./bin/heimdall flash --RECOVERY /tmp/recovery.img --verbose --no-reboot
  • The "no-reboot" option is very important. Do not let android boot at this stage!
  • Now good timing is required
    • Press and hold Power and Vol- until the device reboots
    • As soon as the screen turns black, press and hold Power and Vol+
  • If all went right, Lineage OS recovery is started. It is regognizable by thepink/purple colors and the Lineage OS logo on the top
  • Repeat the whole procesdure in this chapter if anything fails

Flash Lineage OS and optionally Google Apps

  • The device must be in Lineage OS recovery and be connected via USB
  • ADB must be installed on your computer
  • Download Lineage OS from https://download.lineageos.org/devices/gts4lvwifi/builds
    • On the device go to "Apply update", confirm with Power Key
    • Then go to "Apply from ADB", confirm with Power Key
    • Flash with adb sideload /tmp/lineage-21.0-20240320-nightly-gts4lvwifi-signed.zip
  • Optionally download a matching version of Google Apps from https://wiki.lineageos.org/gapps/. You neeed the ARM64 version
    • On the device go to "Apply update", confirm with Power Key
    • Then go to "Apply from ADB", confirm with Power Key
    • Flash with adb sideload /tmp/MindTheGapps-14.0.0-arm64-20240225_232108.zip
    • On the device confirm that the package shall be installed despite that the signature verification has failed.
  • Now you must do another factory data reset. Otherwise boot will fail until you do so.
  • After that you can boot into Lineage OS.
