Q1. The GPS on my Aquaris E5 is very inaccurate and slow to get a location lock. Will this firmware fix it?

This is the most common complaint for the MediaTek version of this phone. Flashing the stock ROM is a highly recommended solution as it resets the phone's GPS configuration and AGPS data, which can significantly improve location accuracy and lock speed.

Q2. My phone gets extremely hot and the battery drains very quickly. What can I do?

A clean firmware flash is an effective way to address software-related overheating and battery drain. It removes rogue background processes and restores the original power management settings. However, the MT6582 chipset is known to run warm, so some heat during heavy use is normal.

Q3. My phone has become very slow and laggy. Will flashing help?

Yes. With 1GB of RAM, the system can get bogged down easily. Reinstalling the firmware removes all software clutter and restores the phone to its original responsiveness, making it much more usable for daily tasks.

BQ Aquaris E5 (3G, MT6582) Firmware (Stock ROM)

The BQ Aquaris E5 (3G Version) was a popular mid-range smartphone from 2015, known for its balanced specifications and clean Android experience. This guide provides the official stock Android 5.0 Lollipop firmware specifically for the MediaTek MT6582 variant. Over the years, users of this model have reported several persistent software issues, most notably a highly inaccurate or slow GPS lock, significant overheating during use, and unpredictable battery drain. For users facing these problems, or those needing to recover a bricked device, a clean flash of the official stock firmware is the definitive solution.

⚠️ CRUCIAL WARNING: 3G MediaTek Version ONLY
This firmware is exclusively for the BQ Aquaris E5 (3G model) which uses a MediaTek MT6582 chipset. It is NOT compatible with the 4G/LTE version, which uses a Qualcomm chipset.

🔧 Device Troubleshooting

The phone is not detected by SP Flash Tool (BROM ERROR): This is a driver issue. Ensure the MediaTek VCOM drivers are properly installed (you may need to disable Windows Driver Signature Enforcement). Use a good quality USB cable and a main USB port. Since the battery is non-removable, you must connect the powered-off phone while holding a volume key (usually Volume Up for this chipset) to force detection.
I get a “PMT changed for the ROM” error in SP Flash Tool: This error means the partition layout is mismatched. To fix this, change the flashing mode in SP Flash Tool from “Download Only” to “Firmware Upgrade” and try the process again.
After flashing, the phone is stuck on the BQ logo: The first boot after a flash can take up to 15 minutes. If it’s still stuck, you must boot into recovery mode (Power + Volume Up), and perform a “Wipe data/factory reset.”
