How to Flash the Stock Firmware
Flashing the stock ROM onto your Acer Iconia One 10 requires a Windows PC and the SP Flash Tool. The process involves installing the MediaTek VCOM drivers, loading the MT8163_Android_scatter.txt file from the firmware into the tool, and then connecting your powered-off tablet to start the flash. This will completely restore your device to its original factory software.

Device-Specific Troubleshooting for Acer Iconia One 10
- Correct Driver Installation: The most common failure point is incorrect drivers. If the tool doesn’t see your tablet, you must install the MediaTek VCOM drivers, which often requires you to disable ‘Driver Signature Enforcement’ in Windows first.
- Using the “Boot Key”: To initiate the flash, ensure the tablet is completely powered off. Press and hold the Volume Down button, and while holding it, connect the tablet to your PC. The tool should then detect it and begin the process. If Volume Down doesn’t work, try holding Volume Up.
- Fixing Google FRP Lock: If you’re locked out of your tablet by Google’s Factory Reset Protection (FRP), flashing this stock ROM will perform a complete wipe and remove the locked account.
- Slow Performance: This is a budget tablet with 1GB of RAM. Over time, it will become slow. A clean flash of the stock ROM is the best way to restore its original performance by removing all accumulated junk files and data. After flashing, be selective about which apps you install to maintain speed.
FAQs
Q1. My tablet is stuck on the Acer logo. Will this fix it?
Yes. Being stuck in a “bootloop” is a classic software problem. Flashing the stock ROM is the most reliable way to fix this issue as it completely reinstalls the device’s operating system.
Q2. Can I upgrade this tablet to a newer Android version?
No. The B3-A20B’s official support ended with its launch version of Android. Due to its MediaTek chipset and lower popularity, the custom ROM community for this specific model is very limited, making unofficial upgrades unlikely.
Q3. What is a “scatter file”?
The scatter file (e.g., MT8163_Android_scatter.txt) is a crucial map for MediaTek firmware. It tells SP Flash Tool the name, size, and location of every partition on the device’s storage, ensuring each part of the software is flashed to the correct place.
Q4. Will this process erase my data?
Yes. Flashing the stock ROM with SP Flash Tool will perform a full factory reset and completely wipe all personal data, apps, and settings from your device.
