Q1. During calls, the screen stays on and my face accidentally mutes the call or opens apps. Can this be fixed?

Yes, this is the most common complaint for the BQ-6045L Nice. It's caused by a poorly calibrated proximity sensor. Flashing the stock firmware is a known and effective solution, as it reinstalls and recalibrates the sensor's drivers, making it function correctly during calls.

Q2. My phone's Wi-Fi connection is very unstable and disconnects frequently. What is the problem?

This is another widely reported software bug. Reinstalling the official firmware restores the modem and wireless drivers to their original, stable state. This process often resolves the bugs that cause these random and frustrating Wi-Fi drops.

Q3. I reset my phone and now it's stuck on the Google account screen. How can I get past it?

You have triggered Factory Reset Protection (FRP). Flashing the stock firmware using this guide will completely wipe the phone's memory, which removes the FRP lock and allows you to set up the device as new without needing the previous Google account.

🔧 Device Troubleshooting

SP Flash Tool gives an authentication or security error: Newer MediaTek chipsets like the Helio A22 can sometimes require a secure boot file. However, this is more often a driver issue. Before searching for special files, first ensure you have the latest VCOM drivers installed correctly and are using an up-to-date version of SP Flash Tool.
The phone freezes a lot, even after flashing: A clean firmware installation removes all software-related causes of freezing. If the problem persists, it is a sign of the phone’s 2GB RAM being a hardware limitation. To improve daily performance, limit the number of widgets on your home screen, uninstall apps you don’t use, and regularly clear the cache of heavy apps like Facebook and Instagram.
The phone is not detected by SP Flash Tool (BROM ERROR): This is a driver or connection problem. Reinstall the VCOM drivers (you may need to disable Windows driver signature enforcement). Use a high-quality USB cable and a main USB port (not a hub). Ensure the phone is completely off before you click “Download” and connect the cable.
