Use a hardware button combination
You can enter download mode with ease if you choose to follow a hardware button combination on your Note 4 – anyway, this method will require some practice, so don’t panic if you don’t manage to access download mode from the first try.
Good; now, first of all, turn off your phablet. Don’t just reboot it, I mean a proper shut down operation: press power button and select “power off” or just press and hold power key for a few seconds.
Then, press and hold volume down, home and power buttons at the same time, for a few moments.
Your device should reboot in download mode.
Now you can safely connect your Note 4 with your computer for resuming the update operation.
Use a dedicated tool from Google Play
Quick Boot app is great as you can use the same for entering download mode automatically.
All you have to do is to install the software on your Note 4.
Launch the same.
Follow on screen prompts and enter your phablet in download mode.
There you have it
