Troubleshooting Common Issues
Here are some specific issues you might encounter with the Celkon CT744 tablet.
1. SPD Upgrade Tool is Stuck on “Checking Baudrate”
Cause: This is a very common issue with Spreadtrum flashing that indicates a driver or connection problem. The computer is unable to establish a stable communication link with the tablet’s chipset.
Solution: Ensure the Spreadtrum drivers are properly installed (reinstall them and restart your PC). Use a high-quality USB cable and connect directly to a main USB port on your computer, avoiding hubs. Most importantly, follow the connection sequence exactly: click “Start,” then press and hold the boot key (usually Volume Down), then plug in the cable.
2. Persistent Malware or Adware After Factory Reset
Cause: Some malware is designed to install itself onto the system partition, which means a standard factory reset (which only wipes the user data partition) will not remove it.
Solution: Flashing the stock .pac firmware is the only guaranteed way to remove these infections. The process completely reformats and rewrites the system partition, erasing all traces of the malicious code and replacing it with a clean, original system.
3. Extremely Slow Performance and Lag
Cause: This tablet’s primary limitation is its hardware, specifically the 1GB of RAM and entry-level processor. Android 5.1 and modern apps will struggle to run smoothly.
Solution: A full firmware flash will restore the tablet to its “best-case” performance by removing all junk files and user data. After flashing, do not install any additional apps if possible. If you must, only use the absolute lightest apps available (e.g., YouTube Go, Facebook Lite) to ensure the device remains usable.
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 phone calls with this tablet?
- Yes. The Celkon CT744 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 CT744. It cannot be used to upgrade to a newer Android version like Marshmallow or Nougat.
- Why doesn’t the SPD Upgrade Tool detect my tablet?
- This is almost always a driver issue. Ensure the Spreadtrum drivers are installed correctly and that you are using the correct “boot key.” Power the tablet off, click Start in the tool, then press and hold either Volume Down or Volume Up *before* you plug in the USB cable. One of them will trigger the download mode.
Conclusion
Restoring the official stock firmware on your Celkon CT744 is the ultimate solution for fixing critical software problems, from bootloops to stubborn malware. This guide provides the authentic firmware and a reliable flashing method to get your tablet back into a usable state.
