STEP 1

Free download OTOFIX D1 Series Flash File:

Otofix D1 Flash File.rar

STEP 2

Prepare all goods required as follows:

1. A TF card (larger than 4G, please backup all personal files)
2. A card reader
3. Windows computer (make sure the windows computer USB port has write permission.)
4. “update.img” file
5. “SDDiskTool”program
6. OTOFIX D1 diagnostic tool which need to be flashed

STEP 3

1.Install Flash File

Copy the "update.img" File:

• Transfer the “update.img” file to your Windows computer.

Prepare the TF Card:

• Insert the TF card into a card reader and connect it to the computer via a USB port.

Set Up the Flashing Tool:

• Decompress the “SDDiskTool_v1.61.zip” file on your computer. Once extracted, you’ll see the “SDDiskTool_v1.61” folder.

Open the folder and run the “SD_Firmware_Tool.exe” program:

• In the tool interface, select “Removable disk.” In most cases, the inserted TF card will be selected automatically.
• If multiple removable disks are connected to your computer, manually select the TF card or remove any other disks to avoid confusion.

Load the Firmware:

• Check the "Firmware upgrade" option
• Click “Select firmware” and choose the “update.img” file.

Start the Flashing Process:

• Click “Start to create.” A warning message will pop up, reminding you that the TF card will be formatted. Ensure any personal files are backed up.
• Confirm by clicking “OK” to proceed.

Complete the Process:

• The process may take about 7 minutes to complete. Once finished, a success message will appear. Click “OK” to confirm.

2.Copy "keepcar.txt" File (Optional)

To avoid resetting the D1 device to factory settings (which preserves the history of diagnostic files and photos), copy the “keepcar.txt” file to the root directory of the TF card.

If you prefer to reset the D1 to factory defaults, simply delete the “keepcar.txt” file from the TF card.

3.Flash OTOFIX D1

Ensure the device's battery level is above 30%.

Insert the TF card into the D1 device you want to flash.

Press and hold the power button to reboot the D1. The device will automatically start the flashing process.

Once the screen displays a success message, you can safely remove the TF card.

4.Configure NV

Transfer Logos and NV Configs:

• Copy the "Logos" and "NvConfigs" files to the device’s internal storage using the ES File Explorer.

Open the "序列号烧录" App:

• Launch the "序列号烧录" App
• The second option, “清除log” (Clear Logo), should be clicked once to remove the existing logo.

Write the New Logo:

• Click “写入logo” (Write Logo), select "otofix," and click OK.

Clear and Set Boot Animation:

• Click “清除开机动画” (Clear Boot Animation) to remove the current boot animation.
• Then, click “设置开机动画” (Set Boot Animation), select "otofix," and click OK.

Write NV Configuration:

• Click “写入NV配置” (Write NV Configuration), select the correct NV configuration, and click OK. The device will automatically restart after this step.

5.Clean Up the System

Reboot the D1:

• Restart the OTOFIX D1 tablet.

Reset to Factory Settings:

• Navigate to System Settings:

System Settings >> System >> Reset >> Factory Data Reset

(Make sure to select “Erase SD card”).

• Confirm by selecting "Reset the Device," and the D1 will reboot automatically.
