There are two ways Acer update:
- Using recovery (to update installed OS)
- Using SP Flash Tool (to recover Acer update)
If you want to install an Acer update using recovery – download the official update, reboot your phone or tablet into recovery mode and click “Install update from SD card”.
If your model is not listed, you can write a comment below. We will solve the problem and give you a link to update the firmware.
