Firmware Update ADVAN Tab VX Neo Unisoc Tiger T606 UMS9230

To update the firmware on your mine ADVAN Tab VX Neo** (Unisoc Tiger T606 / UMS9230), follow these steps carefully. Firmware updates can fix bugs, improve performance, or add new features, but improper flashing can brick your device. Proceed cautiously:

### **1. Official OTA (Over-the-Air) Update**

   - **Check for Updates**:

     1. Connect your tablet to Wi-Fi.

     2. Go to **Settings > System > System Updates**.

     3. Tap **Check for Updates**.

     4. If an update is available, follow the on-screen instructions to download and install it.

   - **Note**: Ensure the battery is ≥50% charged before updating.

### **2. Manual Firmware Update via Recovery**

   If no OTA update is available, you can manually flash the firmware using a **Stock ROM** file.  

   **Requirements**:

   - **Firmware File**: A **.pac file** specifically for the **ADVAN VX Neo (UMS9230)**.  

     - Download from ADVAN’s official support page (if available) or trusted sources like:

       - **ADVAN Indonesia Support**: [Contact Form](https://www.advan.co.id/support)

       - **FirmwareFile.com** or **NeedROM** (search for exact model).

   - **Tools**:

     - **SPD Research Tool** (for Unisoc/Spreadtrum chipsets).

     - **USB Drivers** for your tablet (install on your PC).

   - **Backup Data**: Flashing erases all data. Use Google Backup or third-party apps.

   **Steps**:

   1. **Download Firmware**:  

      Ensure the firmware matches your exact model (e.g., **VX Neo UMS9230**).

   2. **Install USB Drivers**:  

      Download and install drivers for Unisoc devices (e.g., from [SPD Driver](https://spdflashtool.com/download-spd-usb-drivers/)).

   3. **Open SPD Research Tool**:  

      Load the **.pac file** into the tool.

   4. **Enter Download Mode**:  

      - Power off the tablet.

      - Hold **Volume Down + Power Button** until the screen lights up.

      - Connect the tablet to your PC via USB.

   5. **Flash Firmware**:  

      Click **Start** in the SPD Research Tool. Wait until the process completes (5-10 minutes).

   6. **Reboot**:  

      Disconnect the tablet and power it on.

### **3. Precautions**

   - **Battery**: Ensure ≥50% charge to avoid interruptions.

   - **Correct Firmware**: Using the wrong firmware will brick the device.

   - **Antivirus Scan**: Scan firmware files before flashing to avoid malware.

   - **Warranty**: Manual flashing may void your warranty.

### **4. Troubleshooting**

   - **Stuck on Boot Loop**:  

     Re-enter Download Mode and flash the firmware again.

   - **Driver Issues**:  

     Reinstall USB drivers or try a different USB port/cable.

   - **No Firmware Found**:  

     Contact ADVAN support directly via email (e.g., `support@advan.co.id`) or visit an authorized service center.

### **5. Factory Reset (Last Resort)**

   If the update fails or causes issues:

   1. Go to **Settings > System > Reset > Factory Data Reset**.

   2. Confirm and wait for the tablet to reboot.
