Q1. My BQ Aquaris W70 is extremely slow and freezes constantly. Will this fix it?

Yes, it will restore the tablet to its original factory performance. With only 1GB of RAM, this device slows down significantly as apps and data accumulate. A clean firmware flash is the best way to make it usable again, but it is important to manage expectations and only install essential apps afterward.

Q2. The battery percentage on my tablet is unreliable and it shuts down suddenly. What's the cause?

This is a common software calibration issue. Flashing the stock ROM resets the battery management system. After flashing, it is highly recommended to perform a full charge cycle (drain to 0%, then charge to 100% uninterrupted) to help the system relearn the battery's capacity.

Q3. I keep getting errors like "Google Play Services has stopped." How do I stop this?

This indicates corruption in the core system apps. A factory reset is often not enough to fix this. Flashing the full stock firmware is the most reliable way to resolve these errors, as it reinstalls a clean version of all Google apps and services.

BQ Aquaris W70 Firmware (Stock ROM)

The BQ Aquaris W70 is a 7-inch entry-level tablet from 2017 that runs on Android 5.1 Lollipop. Designed for basic media consumption and web browsing, its limited hardware (1GB of RAM) makes it particularly susceptible to software degradation over time. Users of this device commonly report severe performance issues, including constant freezing, extreme sluggishness, and persistent “Unfortunately, [App] has stopped” errors that make the tablet difficult to use. Flashing the official stock firmware is the most effective way to address these problems, restoring the device to its original factory state and making it usable again.

ℹ️ Important Note:
This tablet is powered by a MediaTek MT6580 chipset. The flashing process requires the SP Flash Tool and will completely erase all your personal data. Ensure you have backed up any important files before you begin.

🔧 Device Troubleshooting

SP Flash Tool does not detect the tablet (BROM ERROR): This is a driver issue. Ensure the MediaTek VCOM drivers are properly installed. Use a good quality USB cable and a main USB port on your PC. As this tablet has a non-removable battery, you may need to press and hold the Volume Down or Volume Up button while connecting the powered-off tablet to the PC to force detection.
I get a “PMT changed for the ROM” error in SP Flash Tool: This error can happen after a failed OTA update has altered the partition table. To fix this, change the flashing mode in SP Flash Tool from “Download Only” to “Firmware Upgrade” and try again.
The tablet is stuck on the BQ logo after flashing: The first boot can be slow (up to 15 minutes). If it’s still stuck, you must boot into recovery mode (Power + Volume Up). In the recovery menu, use the volume keys to navigate to “Wipe data/factory reset” and confirm with the power button.
