Samsung Galaxy S8 | FRP Bypass Guide

This comprehensive guide aims to provide a straightforward and reliable method for bypassing the Factory Reset Protection (FRP) on Samsung Galaxy S8 devices. Many existing tutorials and guides on this topic are often convoluted or ineffective, leading to frustration for users. Therefore, this guide has been created to simplify the process and serve as a reliable resource. Please note that the methods described in this guide may differ from other published resources.

Note: Avoid Misleading APK Files

It is important to be cautious of APK files that claim to provide quick solutions for FRP bypass. Instead, follow the proper procedure outlined in this guide for reliable results.

Prerequisites

Before proceeding, make sure you have the following:

  • Samsung Galaxy S8 device
  • Access to a computer running Windows operating system
  • USB cable to connect your device to the computer
  • Stock ROM for your specific device model (can be obtained from Sammobile)

Instructions

Windows Users

If you are using a Windows computer, follow these steps:

  1. Download the appropriate stock ROM for your Samsung Galaxy S8 device from the provided link.

  2. Extract the downloaded file to obtain the necessary firmware files.

  3. Open the flashing tool specific to your device (e.g., Odin).

  4. In the flashing tool, locate the corresponding firmware files within the extracted folder.

  5. Load the firmware files into the appropriate fields, such as AP, BL, and others, as instructed by the flashing tool.

  6. Connect your Samsung Galaxy S8 device to the computer using a USB cable.

  7. Ensure that the device is recognized by the flashing tool.

  8. Once the device is recognized, click the "Start" button to initiate the firmware flashing process.

  9. Wait for the process to complete, and your device will be flashed with the stock ROM.

Gentoo

To install Heimdall (Flashtool for Samsung Devices) on Gentoo, run the following commands:

echo -e "# Heimdall (Flashtool for Samsung Devices)\napp-mobilephone/heimdall qt5" >> /etc/portage/package.use/use
emerge --ask app-mobilephone/heimdall

Device Detection

To detect your Samsung Galaxy S8 device, execute the following command:

heimdall detect

Download PIT

To download the PIT file without rebooting your device, use the following command:

heimdall download-pit --no-reboot --output mydevice.pit

To print the contents of the PIT file without rebooting your device, use the following command:

heimdall print-pit --no-reboot --file mydevice.pit

Boot the Device into Flash Mode

To boot your device into flash mode, follow these steps:

  1. Power off the device.
  2. Press and hold the volume down button along with the power button.

Flashing the Customized ROM

Please note that I cannot upload the customized ROM here due to GitHub policies. You will need to find the ROM yourself using online search engines.

To flash the customized ROM using Odin or a similar tool, follow these steps:

  1. Launch Odin or the flashing tool specific to your device.
  2. Load the ROM file into the appropriate field (e.g., AP).
  3. Leave the other fields blank.
  4. Connect your Samsung Galaxy S8 device to the computer using a USB cable.
  5. Ensure that the device is recognized by the flashing tool.
  6. Once the device is recognized, click the "Start" button to initiate the flashing process.
  7. Wait for the process to complete, and your device will be flashed with the customized ROM.

Custom ROM Developer Mode

Once your device is booted into the customized developer ROM, you will have access to ADB shell. Follow the steps below to proceed:

  1. Open the notification bar.

Note: On the latest firmware, expanding the notification bar using the touchscreen is not possible. You can bypass this by executing the following command:

adb shell cmd statusbar expand-notifications

This will give you control over the notification bar.

  1. Remove any unnecessary settings.

Danger: Be cautious when modifying IMEI settings unless you fully understand what you are doing. Incorrect changes may brick your device.

  1. Delete any accounts added on the device.

  2. Check all settings using the following command:

adb shell settings list global
  1. Adjust settings according to your requirements. Here are some examples:
adb shell settings put global add_users_when_locked 1
adb shell settings put global mobile_data 0
adb shell settings put global add_users_when_locked force_allow_on_external 1
adb shell settings put global charging_sounds_enabled 0
adb shell settings put global bluetooth_on 1
adb shell settings put global boot_count 0
  1. Pull all pre-installed applications using the following commands:
adb pull /system/priv-app/ .
adb pull /system/app/ .

This will allow you to access the pre-installed applications.

  1. While booted into FACTORY BINARY, you can perform additional tricks:

  2. List secure settings:

    adb shell settings secure list

    or

    adb shell content query --uri content://settings/secure

  3. Set "user_setup_complete" to 1:

    adb shell settings put secure user_setup_complete 1

  4. Turn off location:

    adb shell content insert --uri content://settings/secure --bind name:s:location_previous_mode --bind value:s:0

  5. Turn on accessibility:

    adb shell content insert --uri content://settings/secure --bind name:s:accessibility_enabled --bind value:s:1

  6. Turn on accessibility injection:

    adb shell content insert --uri content://settings/secure --bind name:s:accessibility_script_injection --bind value:s:1

  7. Allow non-market apps:

    adb shell content insert --uri content://settings/secure --bind name:s:install_non_market_apps --bind value:s:1

  8. Allow push notifications and receive SMS with a popup in notifications:

    adb shell content insert --uri content://settings/secure --bind name:s:show_note_about_notification_hiding --bind value:s:1

  9. Disable lock feature:

    adb shell content insert --uri content://settings/secure --bind name:s:lock_function_val --bind value:s:0

  10. Allow use of volume buttons:

    adb shell content insert --uri content://settings/secure --bind name:s:volume_controller_service_component --bind value:s:1

  11. Disable lock screen:

    adb shell content insert --uri content://settings/secure --bind name:s:lockscreen.disabled --bind value:s:0

  12. Enable maximum brightness (default: 72):
