The Acer One 7 4G is a 7-inch tablet designed for portability and everyday use, featuring voice calling capabilities. This specific variant is powered by the MediaTek MT6735 (or MT8735W) quad-core processor and runs on Android 8.1 Oreo. This guide provides the official stock firmware package to fully restore your device’s software.
This is a complete firmware package designed for installation using the SP Flash Tool. It’s the ideal solution for fixing significant software issues, such as a device that is bricked (won’t turn on), stuck in a bootloop on the Acer logo, or experiencing severe performance degradation that a factory reset cannot solve.
Disclaimer: Flashing this firmware will perform a clean installation and will completely erase all personal data from the tablet’s internal storage, including your apps, photos, and files. Please back up anything important if you can still access your device.

How to Flash Stock Firmware
To restore your Acer One 7 4G, you’ll use the SP Flash Tool. First, ensure the MediaTek VCOM drivers are correctly installed on your computer.

Power off your tablet completely, then connect it to your PC with a USB cable to begin the flashing process.

Device-Specific Troubleshooting for Acer One 7 4G
- Not Charging or Stuck at 1%: A common issue reported with some Acer tablets is a software glitch where the battery percentage gets stuck, even when charging. A full firmware re-flash is the most effective way to resolve this if a simple factory reset doesn’t work.
- Constant Wi-Fi Disconnections: If your tablet frequently drops its Wi-Fi connection while other devices stay connected, it could be a software or driver issue. Reinstalling the stock ROM ensures that the original, stable wireless drivers are correctly installed.
- “PMT changed for the ROM” Error: If you see this error in SP Flash Tool, it means the partition map on your device is different from the firmware’s. The fix is to change the flashing mode in the tool’s dropdown from “Download Only” to “Firmware Upgrade” and try again.
- Very Slow Performance: While this is a budget tablet, extreme lag or apps crashing can be due to software corruption. Flashing the stock ROM provides a clean, factory-fresh software environment, which often restores the tablet’s original performance.
FAQs
- Q1. My tablet is completely dead and won’t turn on. Can this firmware fix it?
- Yes. If the problem is caused by corrupted software (a “soft brick” or “hard brick”), this full firmware package and the SP Flash Tool method is the standard procedure for reviving it.
- Q2. Will this process delete my photos and files?
- Yes, absolutely. Flashing a stock ROM with SP Flash Tool is a clean installation process that erases everything on the tablet’s internal storage.
- Q3. My PC doesn’t detect the tablet. What should I do?
- This is almost always a driver issue. Uninstall any other phone or tablet drivers from your PC, restart it, and then install the MediaTek VCOM drivers. Connect the tablet only after you have clicked the “Download” button in the SP Flash Tool.
- Q4. Will this remove a Google Account Lock (FRP)?
- No. Restoring the stock firmware does not bypass Factory Reset Protection (FRP). You will still need to enter the credentials of the last Google account that was synced to the tablet to complete the initial setup.
