I've lost my password on my almost new Samsung Galaxy S4. Now I can't unlock the tablet, and I can't shut it down since all these actions require the password. The only thing I can do is restarting it.

Now I want to reset it to factory settings, so I can set a new password. However, all the guides to a hard reset say you have to turn it off first. This I cannot do since it requires the password.

How can I reset or shut down the tablet without a password?

  1. If you have time, let the battery drain. Then power up the tablet with the charger. Press Power + Volume Up to go to recovery (until you see the recovery screen) and reset the tablet.

  2. If not, hold Power + Volume Down for up to 45 seconds to restart the tablet. When it restarts, press Power + Volume Up to go to recovery (until you see the recovery screen) and reset the tablet.

  • Option 2 did it, thanks. 15 seconds were enough. – cheeesus Apr 22 at 15:53
  • Doesn't that trigger FRP (factory-reset protection) without the account being removed prior to reset? Be sure to check if you can run the initial setup before you "give away" the device, @cheeesus – or the "receiver" won't be that happy… – Izzy Apr 22 at 17:17

    @Izzy Thanks for the advice, but at the moment, the device is staying with me. – cheeesus Apr 22 at 21:22
