The Acer One 7 (model B1-780) is an entry-level Android tablet released in 2016. It’s built for basic tasks like web browsing and media viewing, featuring a 7-inch display and powered by a MediaTek MT8163 chipset. This guide provides the official OTA (Over-The-Air) update package, allowing you to manually update your tablet’s software to enhance stability and fix existing bugs.
Important: This file is an OTA update package, not a full unbrick firmware. It is meant for updating a tablet that is already functioning and can boot into its stock recovery mode. This process will not erase your personal data, but creating a backup of important files is always recommended before any software installation.

How to Manually Install OTA Updates
There are two primary methods to install this OTA update on your Acer One 7 (B1-780). The simplest way is to load the downloaded .zip file onto a microSD card, insert it into your tablet, boot into recovery mode, and select the “Apply update from SD card” option. This installs the official update directly on the device without a computer.

Device-Specific Troubleshooting for Acer One 7 (B1-780)
- “Installation aborted” Error: This error in recovery mode usually means the update file cannot verify your current system software. This happens if your device has been rooted, has a modified system partition, or if you are trying to install an update meant for a different region. Ensure your tablet is on stock, unmodified firmware before attempting to apply an OTA.
- Not an Unbrick File: If your tablet is completely dead (won’t power on or get stuck before the boot animation) and cannot enter recovery mode, this OTA file will not help. A dead device requires a full firmware package and the SP Flash Tool to be revived. This OTA file is only for updating a working device.
- Tablet is Very Slow: The Acer One 7 (B1-780) has minimal hardware specs (1GB RAM). While this software update can improve stability, it won’t drastically change performance. If your tablet is very laggy, the most effective solution is to perform a factory data reset from the recovery menu, which will wipe the device and give it a clean start.
- Can’t Enter Recovery Mode: To install this file, you must be able to boot into recovery. To do this, turn off the tablet completely. Then, press and hold the Power + Volume Up buttons simultaneously until the screen turns on. If you cannot get into this menu, you cannot install this update.
FAQs
- Q1. My Acer tablet is stuck on the boot logo. Can this file fix it?
- Possibly. If you can still boot into recovery mode (by holding Power + Volume Up), you can try installing this OTA to fix the boot loop. If you cannot access recovery mode, your device is bricked, and you need a full firmware package, not this OTA file.
- Q2. Will installing this OTA update delete my photos and apps?
- No, applying an official OTA update package via stock recovery does not wipe your user data. However, it is always a wise precaution to back up any important data before starting.
- Q3. Do I need an unlocked bootloader?
- No. Official OTA files are signed by the manufacturer (Acer) and are designed to be installed using the device’s stock recovery on a locked bootloader.
- Q4. What is the difference between this OTA file and a full firmware?
- An OTA (Over-The-Air) file is an update package that patches your existing system to a newer version. A full firmware is a complete system image that can be used to restore a device from scratch, even if it’s bricked.
