You can hard reset the Samsung A300H smartphone if you want to wipe all data and reset its factory settings. Wiping data is common before giving the phone to someone else and resetting the factory settings is common for troubleshooting. If you are troubleshooting and the hard reset doesn’t solve the problems with the software, check for software updates from the Settings app. A new software update will update the firmware. You can also update the firmware using any of the free Samsung firmware update tools.

This tutorial demonstrates how to hard reset the Samsung A300H smartphone.

Caution:

  • A hard reset always wipes all data. You need to take a backup before hard resetting if you plan on restoring any data later. You can back up from the Settings app. If you cannot use your software, connect the phone to the computer and manually transfer any files over to the computer temporarily so you can click and drag them back into the phone folder later.
  • You may need to sign in to your Google account after the hard reset. Make sure you know your Google account email and password before starting the guide. You can reset your Google account password from the Google.com sign-in page if you need to.

How to Hard Reset Samsung SM-A300H

You can hard reset the Samsung A300H from the Settings app and Recovery Mode. We recommend the Settings app unless your software isn’t working or you install custom firmware. Here is how to hard reset from the Settings app:

  1. With the Samsung A300H turned on, tap Settings > Backup & reset.
  2. Tap Factory data reset > Reset device.
  3. Tap Erase everything.

The Samsung A300H smartphone will then be hard reset, all data will be wiped, and its factory settings restored.

You can also hard reset in Recovery Mode. This method is popular for anyone who installs custom firmware, but you can hard reset from Recovery Mode even if you have stock Android. Those who install custom firmware will have a custom recovery partition whereas those with stock Android will have the stock recovery. You boot into both of them with the same hardware button combination. Here is how to use stock recovery first:

Note: When in the stock recovery partition, you navigate with the Volume buttons and confirm your actions with the Power button.

  1. With the Samsung A300H turned off, press and hold the Power + Home + Volume Up buttons simultaneously until Recovery Mode appears.
  2. From the Android System Recovery menu, press Wipe data/factory reset.
  3. Press Yes — delete all user data.
  4. Press Reboot system now.

You can also use Recovery Mode when you have a custom recovery partition. Here is how:

Note: A custom recovery such as TWRP has a touch interface, meaning you can tap the menu using your fingers on the display.

  1. With the Samsung A300H turned off, boot to Recovery Mode by pressing the Power + Home + Volume Up buttons simultaneously until you see TWRP.
  2. Tap Wipe.
  3. Select all the available caches to clear and wipe the data.
    Note: The caching options may vary depending on your version of TWRP. You can potentially install many versions of TWRP, so check which caches you can clear and clear them all.
  4. Tap Reboot from the TWRP main menu.

The Samsung A300H smartphone will boot out of TWRP and restart the Android operating system where you can sign in to your device’s Samsung or Google account again.`
