Firstly we will go through the ADB method. For this method, you will require a PC, a USB cable to connect the device to the PC, and the device.

ADB method:

Start by downloading the SDK platform tool on your desktop which is available on the Android studio. You can download it from the link given below.

Download SDK Platform-Tools

Now follow these steps given below:

  1. Extract the file on your desktop
  2. Place the file inside the extracted folder
  3. Now open the command prompt you can do that by holding the left shift, right-click the mouse and then select ‘open command prompt here’.
  4. The command prompt will open

Now set up your device, to do this:

  1. Shut down the phone
  2. Enter into recovery mode by holding the Power+volume up buttons.
  3. Select the ‘update via ADB’ recovery mode (To scroll up or down press the volume up and volume down button and to select the option press the power button).
  4. Now connect the phone to the PC using the Samsung USC cable.
  5. Now go to the command prompt enter the following command: ‘./adb devices’.
  6. Wait for some time and you will discover that the process is started and your device is found.
  7. After your device is recognized run the following command: ‘./adb sideload’

The final process will now start and you will see the percentage on your screen. The process may take some time, do not remove the cable, disconnect your phone, or power off your PC.

After the completion of the process, the phone will automatically reboot and then you can disconnect your phone.

SD-card method:

This is the second method after the ADB method. If you are not able to update your device using the previous ADB method you can try this method, it is simpler.

Here are the steps you need to follow:

  • Download the bin file and rename it as
  • You can rename the file by going through the file option in the windows 10 on your PC.
  • Then copy the file to the file directory of your SD-card

Now, set up your device, to do this:

  • Hold the Power+Volume up button of your device to go to the stock recovery mode.
  • Now go to the ‘update via SD-card’ option
  • To do this use the volume up and volume down buttons for navigating between the option and power button to select the option.
  • Then select the file by using the volume buttons and select the file using the power button
  • After you press the power button the process will start.
  • Now, wait until the process completes. It will take some time
  • After the process completes the phone will automatically reboot.


  1. For now, after installing the beta update it isn’t possible to reboot into recovery via the Volume UP + power button.
  2. You will have to use ADB for that: “./adb reboot recovery”
  3. For reboot to Download mode use the following command: “./adb reboot download”
  4. Installing via this way shouldn’t trigger the KNOX warranty void.
  5. However: updating to Beta is your own choice, no one is responsible if anything goes wrong

How to capture

HTTP Canary app

1. Load canary
2. Start the update download but don’t pause it.
3. Go back to canary and start that and it will grab the link.


  1. After installing the update, CLEAR your cache by going into recovery (VolUP – Power)
  2. If you’re NOT officially registered via Samsung Members, you won’t receive OTA: you’ll have to update every time MANUALLY with the above method!
  3. The files are for Multi-CSC OXM only (so NOT for the South American countries which have Multi-CSC OWO or Multi-CSC OXB)
