How to Flash Firmware on BQ Mobile BQ-5202 Space Lite
To install the stock ROM on your BQ-5202, you will use the SP Flash Tool. After extracting the firmware, you need to load the scatter file (e.g., `MT6737M_Android_scatter.txt`) into the application. Ensure the flashing mode is set to “Download Only.” Then, power off your phone completely. Click the “Download” button in SP Flash Tool and immediately connect your phone to the computer with a USB cable to begin the installation.

Device-Specific Troubleshooting
- SP Flash Tool shows a “BROM ERROR”: This is the most common flashing error and indicates a communication failure. To resolve this, ensure the MediaTek VCOM drivers are correctly installed. Try a different USB port and cable. Also, try pressing and holding the Volume Down key just before you connect the powered-off phone to the PC.
- Phone is Still Slow After Flashing: The BQ-5202 has 1GB of RAM, which is very limited for modern apps. While flashing provides a clean system, performance can quickly degrade. After flashing, perform a factory reset from recovery mode and be selective about the apps you install to maintain system speed.
- Invalid IMEI or No Mobile Network: This critical issue happens if the NVRAM partition is erased, usually by accidentally using the “Format All + Download” option in SP Flash Tool. This option should never be used. If your IMEI is lost, you will need specialized tools to restore it.
- Flash Successful, but Phone Stuck at BQ Logo: If the flashing process completes with a green checkmark but the device still won’t boot past the logo, you should manually enter recovery mode. To do this, hold Power + Volume Up until the recovery menu appears. From there, select “Wipe data/factory reset” and then “Reboot system now.”
FAQs
- Q1. Will reinstalling the firmware make my phone faster?
- Yes, it will restore the phone to its original factory performance by removing all software bloat, junk files, and potential malware. However, due to the limited 1GB of RAM, it is important to manage apps and storage carefully to keep it running smoothly.
- Q2. What is the difference between “Download Only” and “Firmware Upgrade” modes?
- “Download Only” is the safest mode; it flashes the partitions listed in the scatter file without altering the partition layout. “Firmware Upgrade” is more comprehensive and can re-partition the storage. You should always use “Download Only” unless you encounter a specific error like “PMT changed for the ROM.”
- Q3. My PC does not recognize the phone. What should I do?
- This is a driver problem. Uninstall any previous MediaTek drivers from your computer and reinstall the correct VCOM drivers. You may need to disable Driver Signature Enforcement on Windows 10/11 for the drivers to install correctly.
