How to add a Google account to Xiaomi Redmi 9C: all ways and solutions to errors

Adding a Google account to a Xiaomi Redmi 9C smartphone is a must-have for the device to be fully used. Without it, you can’t download apps from the Play Market, sync contacts, photos or backups. However, many users face difficulties: the system asks for a password from the previous account, sync errors occur, or the device does not offer to add a profile at all when you first turn on.

In this article, we will look at all the possible ways to add a Google account to the Redmi 9C, from the standard method through settings to bypassing locks after reset. We will focus on the unique nuances of MIUI 12/13 that distinguish the process on Xiaomi from pure Android. If you bought a used phone or encountered an error "This device was reset", here you will find working solutions.

Why can’t I add a Google account to Redmi 9C?

The problem with adding a Google account to the Xiaomi Redmi 9C is usually due to one of three reasons:

• 🔒 Factory Reset Protection FRP – activated after resetting if a Google account was linked to the device.
• 📱 Outdated version MIUI — Firmware older than 2022 may not have current Google services.
• 🚫 Region restrictions — On some versions of Redmi 9C for China (MIUI China), Google services are removed at the firmware level.

If you try to add an account and see a message saying, "This device has been reset. To continue, log in to the Google account that previously synced with this device," it means that FRP- lock is triggered. The only way to solve the problem is to know the previous owner's data or bypass (we will talk about it in the corresponding section).

⚠️ Warning: Redmi 9C with MIUI China firmware (without Google services) cannot add an account through standard settings. You will need to pre-instal Google Installer or flash it to the global version.

Method 1: Standard account addition via settings

If your Redmi 9C is not locked and you have a global firmware (MIUI Global) installed, add your account as follows:

1. Open the settings (cog icon on the desktop).
2. Go to Accounts and Sync (or Passwords and Security → Accounts in new versions of MIUI).
3. Click Add Add Account → Choose Google.
4. Enter your email address and password. If you don't have an account, click Create an account.
5. Accept the terms of use and set up synchronization options (contacts, calendar, photos).

After successful addition, check the services:

• 📱 Open Play Market – If the app is running without errors, the account is added correctly.
• ☁️ Go to Settings → Accounts → Google and make sure that you have the right data sync enabled.
• 🔄 Reboot your phone – sometimes Google services only start working after a reboot.

⚠️ Warning: If you add a Play Market account and you have a No Internet connection error, check the date and time settings. Redmi 9C often gets automatically synced, manually set the date or enable Network Auto Determine in your time settings.

Method 2: Adding an account when you first turn on your phone

If you’ve just bought a Xiaomi Redmi 9C or made a full reset, the system will suggest adding a Google account at the initial setup stage, which is the most reliable method, as it minimizes the risk of synchronization errors.

Step-by-step:

1. Turn on your phone and select your language.
2. Connect to Wi-Fi (required! without the Internet, you can't add an account).
3. In the “Copy Data” step, select Do Not Copy (if the phone is new) or Copy from another device (if you are recovering data).
4. On the “Add Account” page, click Google and enter the data.
5. Accept the terms of use and complete the setup.

If you are unable to connect to Google servers at this point, try:

• 🔄 Reconnect to another Wi-Fi network (sometimes the lock occurs at the router level).
• 📶 Enable mobile internet (if SIM- card is installed) and try again.
• ⏳ Wait 10-15 minutes and try again – sometimes Google servers are temporarily unavailable.

Method 3: Bypass FRP-locking (if the phone requires an old account)

If Redmi 9C asks you to enter your previous Google account (FRP error) after resetting, there are several ways to bypass the lock, and it is important that these methods only work on MIUI 12-14 firmware and may stop working after security updates.

Method 1: Emergency Call (for MIUI 12)

1. On the lock screen, press Emergency Call.
2. Enter the combination ##4636## and the test menu will open.
3. Select Settings → Data Reset and confirm the reset.
4. After the reboot, the phone will prompt you to reconfigure the device without checking FRP.

Method 2: Through OTG- cable and file manager (OTG- adapter and flash drive required):

1. Download to the APK- file of any file manager (e.g., FX Explorer).
2. Connect the flash drive to the phone through OTG-adapter.
3. On the lock screen, click Settings → About Phone → MIUI version (click 7 times until the developer mode message appears).
4. Return to Settings → Additional → For developers and enable USB debugging.
5. Install the file manager from the flash drive and delete files through it: /data/system/gesture.key /data/system/locksettings.db
6. Restart the phone – the FRP lock will be reset.

⚠️ Warning: Deleting system files can cause the phone to run unstable. After bypassing FRP, be sure to complete a full reset via Settings → Reset and set up the device again.

Method 4: Install Google Services on MIUI China

Some versions of Redmi 9C for the Chinese market (MIUI China) have removed Google services at the firmware level, in which case a standard account addition is not possible – you need to install the Google Mobile Services (GMS) package first.

Instructions:

1. Download the Google Installer installation package from the official Xiaomi forum (e.g. link).
2. Transfer the.apk file to your phone (via USB or cloud storage).
3. In your phone settings, enable installation from unknown sources: Settings → Applications → Application Management → Browser (or Files) → Allow installation from this source.
4. Install Google Installer and run it. Follow the instructions on the screen.
5. After installing, restart your phone and try adding an account through Settings → Accounts.

If the Play Market fails to open after installation or if it says “Google Play Services are stopped” you should follow the following steps:

• 🔄 Reboot the phone.
• 📌 Update all Google apps through the Play Market.
• 🗑️ Clear the Google Cache: Settings → Apps → App Management → Google Play Services → Storage → Clear the cache.

Solving common errors when adding an account

Even after successfully adding a Google account to Redmi 9C, there may be errors, and let’s look at the most common ones and fixes.

Error 1: "Can't log in. Check the Internet connection."

Causes and solutions:

• 🌐 Wi-Fi problems – connect to another network or turn on mobile internet.
• 🕒 Wrong time – set the date and time automatically in the settings.
• 🔒 Google Block — if you change accounts frequently, Google may temporarily block access. Wait 24 hours or use another account.

Error 2: "This device is not certified"

This error occurs if the Redmi 9C firmware is modified or the phone is not certified by Google.

• 📱 Go to Settings → About Phone and click on MIUI Version several times to activate Developer Mode.
• 🔧 Go back to Settings → Additional → For developers and enable OEM unlocking.
• 🔄 Reboot your phone and try to log in again.

Error 3: Account added, but sync is not working

If your contacts, photos or mail are not synchronized:

• ☁️ Check your sync settings: Settings → Accounts → Google → Account Sync.
• 🗑️ Clear the cache of Google apps: Settings → Apps → Google Play Services → Storage → Clear the cache.
• 📥 Update all Google apps through the Play Market.

💡

If Gmail doesn’t update emails after adding an account, check the traffic saving settings in MIUI. Go to Settings → Battery and Performance → Traffic Savings and disable restrictions for the Gmail app.
