The Acer One 7 (model B1-790) is a compact, entry-level 7-inch tablet from 2017 designed for basic media consumption and web browsing. This page provides an official OTA (Over-The-Air) update package for the device. For owners of this tablet, manually installing a software update is a good way to apply the latest available bug fixes and improve the overall stability of the Android 6.0 Marshmallow operating system.
Important Note: This is an OTA update package, not a full firmware for unbricking a dead device. It must be installed on a functioning tablet. Your device must also be on 100% stock, un-rooted firmware with the original recovery for the update to install successfully.

- Via Stock Recovery: Download the `.zip` file and move it to your internal storage or SD card. Power off the tablet, then boot into recovery mode (hold Volume Up + Power). Select `Apply update from…` and choose the `.zip` file.

How to Manually Install Official OTA Updates on Android
FAQs
Q1. Will this update make my tablet faster?
An OTA update can improve performance by fixing software bugs. However, the biggest limitation of the Acer One 7 is its 1GB of RAM. A clean update will restore it to its best possible speed, but it will still be slow with modern apps and web pages. It is best suited for single-tasking and light media viewing.
Q2. My tablet is stuck on the Acer logo. Can I use this OTA file to fix it?
It depends. If you can still access the stock recovery mode (usually by holding Volume Up + Power), you can try to “sideload” or “apply update from SD card” using this OTA file. However, if recovery is not accessible, you will need a full SP Flash Tool firmware package to unbrick the tablet, not this OTA file.
Q3. Can I update this tablet to Android Nougat or a newer version?
No. Android 6.0 Marshmallow was the final official operating system released by Acer for this model. This update is a patch for Marshmallow.
Device-Specific Troubleshooting
- “Insufficient Storage” to Install Update: The 16GB of storage is very limited. If the update fails to install due to lack of space, you will need to free up several hundred megabytes. The best way is to insert a microSD card, move all photos and videos to it, and then go to `Settings > Apps` to uninstall any apps you don’t need and clear the cache for remaining apps.
- Poor Battery Life: A clean software update can help resolve bugs that cause battery drain. To maximize the life of the 2780 mAh battery, reduce the screen brightness, turn off Wi-Fi and Bluetooth when not in use, and check `Settings > Battery` to see if any specific app is consuming too much power.
- Unstable Wi-Fi Connection: This update may contain updated drivers for the Wi-Fi hardware. If you still experience issues after installing the OTA, try resetting the network settings via `Settings > Backup & reset > Network settings reset`. This will clear saved passwords but can fix persistent connection problems.
- “Verification Failed” During Installation: This error is definitive. It means your system has been modified (rooted, custom recovery) or you are on a custom software version. This official OTA will only install on a 100% stock, un-rooted device. You must flash a full SP Flash Tool firmware first to restore the tablet to its original state.
