How to Flash the Firmware: 5 Key Steps
This is a high-level overview of the flashing process using SP Flash Tool. For a full, safe, and detailed guide, you must click through to our main pillar article linked below.
- Prepare Your PC: Download and install the required MediaTek VCOM USB drivers to ensure your computer can communicate with your phone.
- Load the Firmware: Launch SP Flash Tool and load the firmware by selecting the `…scatter.txt` file from the extracted firmware folder (e.g.,

Troubleshooting Common Issues
1. Abnormal Battery Drain After Flashing
Cause: The 5507L Iron Max’s key feature is its large 4010 mAh battery. After a full firmware flash, the Android system’s battery statistics can become miscalibrated, leading to incorrect percentage readings or what appears to be rapid battery drain.
Solution: You need to recalibrate the battery. After flashing, use the phone normally until the battery drains completely and the phone shuts off. Then, charge it to 100% in a single, uninterrupted session. Repeating this 2-3 times will help the OS re-learn the battery’s capacity and provide accurate readings.
2. SP Flash Tool BROM Error 4032
Cause: This common MediaTek error usually indicates a problem with the USB drivers, the SP Flash Tool version, or the connection timing, preventing the tool from communicating with the phone’s memory.
Solution: Ensure you have correctly installed the VCOM drivers and have rebooted your PC. Use a high-quality USB cable. If the error persists, try using a slightly older version of SP Flash Tool. A common trick is to click “Download” and then connect the phone while holding the Volume Down key.
3. Fingerprint Scanner Not Responding
Cause: The fingerprint scanner can stop working due to a software glitch, a corrupted driver, or a hardware failure. If it happened after a failed update or installing a certain app, it is likely a software issue.
Solution: Flashing the stock ROM is the best way to fix software-related fingerprint scanner problems, as it reinstalls the original factory drivers and software. After flashing, go to the security settings and try to register a new fingerprint.
Frequently Asked Questions (FAQs)
- Can I upgrade the BQ Mobile 5507L Iron Max to Android 8.0 Oreo?
- No. The firmware provided, Android 7.0 Nougat, is the final major software version officially released for the BQ Mobile 5507L Iron Max. There are no official updates to newer Android versions for this model.
- Why is the phone called “Iron Max”?
- The name likely refers to its key features: “Iron” for a potentially durable, metal-accented build, and “Max” for its maximum-capacity 4010 mAh battery, which was the main selling point of the BQ Mobile 5507L Iron Max.
- Will this firmware remove the Google FRP lock?
- In most cases, yes. A full firmware flash with SP Flash Tool typically overwrites the partition that stores the Factory Reset Protection (FRP) lock. For stubborn locks, the “Format” tab in the tool can be used to manually erase the FRP address.
- Is 16GB of storage enough for this phone?
- While usable for basic apps, 16GB of storage on the BQ Mobile 5507L Iron Max will fill up quickly. After the OS and pre-installed apps, you are left with limited space. A microSD card is highly recommended for storing photos, videos, and other media.
Conclusion
Restoring your BQ Mobile 5507L Iron Max with its official stock firmware is the definitive solution for overcoming software problems, especially issues like battery drain and system lag. By using SP Flash Tool correctly and following the detailed instructions in our main pillar guide, you can successfully unbrick your phone and restore its impressive battery life.
