Troubleshooting Common Issues

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

1. Extremely Slow Performance (Unusable Lag)

Cause: The Celkon Pop’s primary limitation is its hardware, specifically the 512MB of RAM. Android 5.1 Lollipop and even the most basic modern apps can struggle to run on such limited memory.

Solution: A full firmware flash will restore the phone 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., Opera Mini for browsing). This device is not suitable for social media or modern apps.

2. SPD Upgrade Tool Error: “Failed: Uart send error”

Cause: This is a very common error with the SPD tool that indicates a problem with the driver or USB connection. The tool is failing to establish a stable communication link with the phone.

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, not a hub. Finally, make sure you press and hold the boot key (Volume Down) *before* plugging in the cable.

3. Phone is Infected with Malware or Adware

Cause: Ultra-budget phones are often targeted by malicious software that can be difficult to remove.

Solution: Flashing the stock .pac firmware is the only guaranteed way to remove deep-level infections. The process completely reformats the phone’s storage, wiping out any malicious code and replacing it with a clean system.

Frequently Asked Questions (FAQs)

Will this firmware remove a forgotten password or pattern lock?

Yes. The flashing process erases all user data on the phone, which includes any screen lock security like PINs, passwords, or patterns. Your phone will be completely reset.

Can I install WhatsApp on the Celkon Pop?

It is not recommended. With only 512MB of RAM, the app will run extremely poorly, likely crashing or freezing constantly. The phone is not powerful enough for modern messaging apps. You may be able to use a very old, unsupported version, but this is not advised.

Does this phone support 4G?

No. The Spreadtrum SC7731 chipset in the Celkon Pop is a 3G-only processor. It does not have the hardware to connect to 4G LTE networks.

Why doesn’t the SPD Upgrade Tool detect my phone?

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 phone 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 Pop 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 compact device back into a usable state.
