Preparing for installation using Heimdall

Samsung devices come with a unique boot mode called “Download mode”, which is very similar to “Fastboot mode” on some devices with unlocked bootloaders. Heimdall is a cross-platform, open-source tool for interfacing with Download mode on Samsung devices. The preferred method of installing a custom recovery is through this boot mode – rooting the stock firmware is neither necessary nor required.

Please note: On windows PC’s to run the installation using ODIN check this HOWTO. The steps given below explain how to install Heimdall and flash /e/OS

1. Enable OEM unlock in the Developer options under device Settings.

   It appears sometime that the OEM unlock option is missing from Development options, especially on new devices. Please connect your device to the wifi and check of system updates. After a reboot, the option should appear.

   2. Choose Options » List all devices from the menu.

   4. Click Replace Driver (having to select Install Driver from the drop down list built into the
   5. If you are prompted with a warning that the installer is unable to verify the publisher of the driver, select Install this driver anyway. You may receive two more prompts about security. Select the options that allow you to carry on.

6. On the computer, open a command prompt (on Windows) or terminal (on Linux or macOS) window, and type:

    heimdall print-pit
   

7. If the device reboots, Heimdall is installed and working properly.

Installing a custom recovery using Heimdall

1. Download the custom recovery linked in the Download section above

2. Power off the device and connect the USB adapter to the computer (but not to the device, yet).
3. Boot into download mode:
   • With the device powered off
   • hold Volume Down + Power

   Accept the disclaimer, then insert the USB cable into the device.

4. On the computer, open a command prompt (on Windows) or terminal (on Linux or macOS) window in the directory the recovery image is located, and type:

   heimdall flash --RECOVERY recoveryfilename.img --no-reboot
   

   Replace the recoveryfilename with the name of the recovery image you downloaded

5. A blue transfer bar will appear on the device showing the recovery being transferred.
6. Unplug the USB cable from your device.
7. Manually reboot into recovery:
   • With the device powered off, hold Volume Up + Home + Power

   Note: Be sure to reboot into recovery immediately after having installed the custom recovery. Otherwise the custom recovery will be overwritten and the device will reboot (appearing as though your custom recovery failed to install).

Installing /e/ from recovery

1. Before proceeding ensure you have downloaded the /e/OS for your device, from the link given in the Downloads section above

2. If you aren’t already in recovery mode, reboot into recovery mode by typing the below command in the console of an adb enabled PC

    adb reboot recovery
   

   Tip: You can also do this manually using the below key combination
   • With the device powered off, hold Volume Up + Home + Power

3. In TWRP return to main menu, then tap Wipe

4. Now tap Format Data and continue with the formatting process.

   Here a new screen may show where you will have to type Yes and confirm the action by clicking a button.

   Caution: Format Data will remove encryption as well as delete all files stored on the internal storage. Remember to take a backup first. Check Requirements section above.

5. Return to the previous menu and tap Advanced Wipe.

6. Select the Cache and System partitions to be wiped and then Swipe to Wipe

7. Sideload the /e/ .zip package.

   Tip: Sideload requires actions in two places to be done. One on your phone in the TWRP UI and secondly on the connected PC which should have adb enabled. Also note the sideload process while running may stop abruptly around 50%. The console would show a message Total xfer: 1.00x. This would mean that the transfer has successfully completed.
   • On the device in TWRP,

     select Advanced, ADB Sideload, then swipe to begin sideload.

   • On the host machine, in the console , start the sideload of the package by typing
