Q1. The in-display fingerprint scanner on my Aurora is slow or fails to recognize my finger. Will this firmware fix it?

It very often can. This is the most common software complaint for this model. Flashing the stock ROM reinstalls the original drivers and calibration files for the optical scanner. For best results after flashing, clean the screen thoroughly and carefully re-register your fingerprints in a well-lit room.

Q2. Can I fix the AMOLED screen burn-in (ghost images) by flashing this firmware?

No. Screen burn-in is a physical degradation of the organic pixels in the AMOLED panel. It is a permanent hardware issue, and no software update or firmware flash can repair or reverse it.

Q3. My phone gets very hot when playing games. Will a firmware flash help?

It can help. A clean installation of the OS ensures there are no rogue background apps or services consuming CPU resources. This allows the Helio P60 chipset to manage its thermals more efficiently during intensive tasks like gaming, potentially leading to cooler operation.

BQ Mobile BQ-6430L Aurora Firmware (Stock ROM)

The BQ Mobile BQ-6430L Aurora stands out as one of BQ’s more ambitious devices, featuring a premium 6.4-inch FHD+ AMOLED display, an in-screen fingerprint scanner, and the powerful MediaTek Helio P60 processor. While capable, the device is not without its specific, user-reported issues. The most significant complaints involve an unreliable or slow in-display fingerprint scanner and the complexities of flashing the device due to its secure chipset. For users looking to resolve persistent software bugs, bypass an FRP lock, or recover from a bootloop, installing the official stock firmware is the solution, but it requires special steps.

⚠️ CRUCIAL WARNING: Secure Boot and Authentication Bypass Required
This device is powered by a MediaTek Helio P60 chipset with Secure Boot. A standard attempt to flash with SP Flash Tool will fail. You must use an MTK Auth Bypass Tool to disable security protections before you can flash the firmware. This procedure is for advanced users and carries risks if not done correctly. It will also erase all your data.

🔧 Device Troubleshooting

SP Flash Tool shows an authentication error or is stuck at “Download DA 100%”: This is the expected error if you have not used the MTK Auth Bypass tool correctly. You must successfully disable authentication before attempting to use SP Flash Tool. Reread the flashing guide and follow the steps precisely.
The phone is stuck in a bootloop after a successful flash: The first boot after a full flash can take up to 20 minutes on this device. If it is still stuck, you need to perform a factory reset. Boot into recovery mode (Power + Volume Up), select “Wipe data/factory reset,” and then reboot.
The phone is not detected by the Auth Bypass Tool or PC: This points to a driver issue. Reinstall the MediaTek VCOM drivers (you may need to disable Windows Driver Signature Enforcement first). Try a different USB port and a known good USB-C cable. Ensure the phone is completely off before connecting it while holding the volume buttons.
