Hard Reset Samsung Galaxy S21 Ultra (China Version) Complete Guide

This guide explains how to factory reset the Samsung S21 Ultra China Version safely and correctly, especially when the device is locked, unresponsive, or stuck on the Samsung logo.

✅ Important Warning Before You Hard Reset (FRP Lock)

Before performing a hard reset, make sure you know the Google account (Gmail) and password previously used on the device.
Samsung devices, including the China Version, use FRP Factory Reset Protection, which will require the same Google account after the reset.
If you do not remember it, the phone may remain locked after reboot.

✅ Important Notes Before Starting

  • Charge your phone to at least 50%.
  • A factory reset will erase all data (photos, apps, messages, accounts).
  • Remove any linked Samsung Account or Google Account if the device is still accessible.
  • The steps below apply specifically to the China variant (SM-G9980).

How to Hard Reset Samsung Galaxy S21 Ultra China Version (SM-G9980)

This method is for devices that are locked, frozen, or cannot access settings.

Power Off the Device

If the phone is stuck, hold Power + Volume Down until it turns off completely.

Enter Recovery Mode

  1. Press and hold Volume Up + Power together.
  2. Keep holding until you see the Samsung logo, then release both buttons.
  3. Wait a moment the Android Recovery Menu will appear.
If “No Command” appears:
  • Press Power + Volume Up once together to show the recovery menu.

Wipe Data / Factory Reset

In the recovery menu:
  1. Use Volume buttons to move.
  2. Highlight: Wipe data / factory reset
  3. Press Power to confirm.
  4. Select: Factory data reset
  5. Wait for the process to complete.

Reboot the Device

After the reset is done:
  • Choose Reboot system now
Your Samsung S21 Ultra China Version will restart and return to the initial setup screen.

✅ Why This Method Is Important for the China Version

The China version of the S21 Ultra does not come with Google services pre installed, and users often sideload apps or custom firmware. This may lead to:
  • Boot loops
  • System instability
  • Google installation errors
  • Freezing and slow performance
A hard reset via recovery mode is the best method to restore system stability on Chinese variants.
