Samsung Galaxy Tab T230NU Factory Reset via Recovery or Settings

User question

how to factory reset Samsung Galaxy Tab T230nu

Artificial Intelligence Response

Direct answer to the question

To factory reset a Samsung Galaxy Tab 4 7.0 SM-T230NU, you can reset it in either of two ways:

• From Android Settings — if you can still unlock and use the tablet.
• From Recovery Mode using hardware buttons — if the tablet is locked, frozen, boot-looping, or you cannot access Settings.

A factory reset erases apps, accounts, photos, downloads, settings, and internal storage data, so back up anything important first.

Method 1: Factory reset from Settings

Use this method if the tablet still works normally.

1. Open Settings.
2. Go to General.
3. Tap Backup and reset.
4. Tap Factory data reset.
5. Tap Reset device.
6. If asked, enter your PIN, password, or pattern.
7. Tap Delete all.
8. Wait for the tablet to erase itself and reboot.

After rebooting, it will show the initial setup screen, like a new device.

Method 2: Hard reset using buttons / Recovery Mode

Use this if you cannot get into the tablet.

1. Power off the tablet completely.

   • If it is frozen, hold the Power button for about 10–15 seconds until it shuts off.

2. Press and hold these buttons together:

   Volume Up + Home + Power

3. When the Samsung Galaxy Tab 4 logo appears, release the Power button but keep holding Volume Up + Home.

4. When the Android system recovery menu appears, release all buttons.

5. Use the Volume Down button to highlight:

   wipe data/factory reset

6. Press the Power button to select it.

7. Use Volume Down to highlight:

   Yes — delete all user data

8. Press Power to confirm.

9. Wait until the reset finishes.

10. When you return to the recovery menu, select:

    reboot system now

11. Press Power.

The first boot after reset can take several minutes.

Important notes

• Make sure the battery is charged, preferably at least 50%, or keep the tablet plugged in.
• If the tablet was using a Google account, you may need to sign in with the same Google account after reset. This is due to Android Factory Reset Protection on some firmware versions.
• If you are selling or giving away the tablet and can still access Settings, remove your Google account first:
  • Settings → Accounts → Google → Remove account
• Do not choose Download Mode/Odin Mode. That is usually entered with Volume Down + Home + Power and is for firmware flashing, not factory reset.

If Recovery Mode does not appear

Try this timing:

1. Turn the tablet fully off.
2. Hold Volume Up + Home + Power.
3. As soon as the Samsung logo appears, release Power only.
4. Keep holding Volume Up + Home until the recovery menu appears.

If it still will not enter Recovery Mode, the buttons may be faulty, the battery may be too low, or the firmware may be corrupted.

Brief summary

For the Samsung Galaxy Tab SM-T230NU, the hard reset button combination is:

Power off → hold Volume Up + Home + Power → choose wipe data/factory reset → Yes → reboot system now.
