How to Flash Celkon CT711 Firmware

This is a summary of the flashing process using SP Flash Tool. For a more comprehensive guide with screenshots, please visit our detailed pillar article.

1. Preparation: Download and extract the firmware, SP Flash Tool, and MTK VCOM drivers to a folder on your PC.
2. Driver Installation: Install the MediaTek VCOM drivers. You may need to disable driver signature enforcement on modern Windows versions for the drivers to install correctly.
3. Load Firmware in Tool: Launch flash_tool.exe. Click on the “Scatter-loading File” button, navigate to the extracted firmware folder, and select the MT8321_Android_scatter.txt file.
4. Begin Flashing: Set the dropdown box to “Download Only”. This is a critical step to avoid erasing your tablet’s IMEI number. Click the large green “Download” button to put the tool in standby.
5. Connect the Tablet: Power off your Celkon CT711 completely. Press and hold the Volume Down key and connect the tablet to your PC with a USB cable. Release the key once the flashing process begins. A green tick will appear in the tool when it has finished successfully.

Troubleshooting Common Issues

Here are some specific issues you might encounter with the Celkon CT711 tablet.

1. “Invalid IMEI” or SIM Card Not Working

Cause: This is a very common issue on MediaTek devices. It happens when the NVRAM partition, which stores your tablet’s unique IMEI numbers, gets corrupted or erased. This is almost always caused by using the “Format All + Download” option in SP Flash Tool.

Solution: Always flash using the “Download Only” mode. If your IMEI is already lost, flashing this stock ROM is a necessary first step, but it will not restore the IMEI by itself. You will need to find your original IMEI (on the tablet’s box or sticker) and use advanced tools like Maui META to write it back to the device.

2. Tablet is Unresponsive or Dead (Hard Brick)

Cause: A failed update, incorrect file flash, or a critical system error can cause the tablet to become completely unresponsive.

Solution: SP Flash Tool is excellent at recovering from this state. As long as your PC can detect the tablet’s MTK Preloader port when you plug it in (you might hear a connection sound), the tool can force-flash the stock firmware and bring the device back to life.

3. Extremely Slow and Laggy Performance

Cause: The Celkon CT711 has entry-level hardware (1GB RAM). Android 5.1 and modern apps will struggle to run smoothly on such limited memory, especially on a tablet’s larger screen.

Solution: A full firmware flash will restore the tablet to its “best-case” performance by removing all junk files and user data. After flashing, be very selective about the apps you install. Use “Lite” versions of apps like YouTube Go and Facebook Lite to conserve system resources.

Frequently Asked Questions (FAQs)

Will this firmware remove a forgotten password or pattern lock?

Yes. The flashing process erases all user data on the tablet, which includes any screen lock security like PINs, passwords, or patterns. Your tablet will be reset to its factory state.

Can I make regular phone calls on this tablet?

Yes. The Celkon CT711 is a “calling tablet” and has a SIM card slot for 3G data and voice calls, allowing you to use it like an oversized phone.

Can I upgrade to a newer version of Android with this file?

No. This is the official Android 5.1 Lollipop firmware for the Celkon CT711. It cannot be used to upgrade to a newer Android version like Marshmallow or Nougat.

What does a BROM ERROR in SP Flash Tool mean?

This is a communication error, usually caused by incorrect VCOM drivers. Ensure the drivers are properly installed (you may need to disable driver signature enforcement on Windows). Also, try using a different USB cable or port and make sure you connect the tablet after clicking the “Download” button.

Conclusion

Restoring the official stock firmware on your Celkon CT711 is the most reliable way to fix major software issues, from a bootloop to critical IMEI and network problems. This guide provides the authentic firmware and a safe flashing method to get your device back into working order. Remember to be very careful with the flashing options to protect your device’s IMEI number, and always back up your data first.
