    • Hi, after doing update to latest operating system or firmware, we suggest to do hard reset or master format, because maybe some previous installed applications may not compatible with latest firmware at your Acer Iconia A3. You can use software menu to do hard reset, otherwise you need to do hard reset this Acer tablet using hardware button like #Option 2 above.

    • Hi, please try to use OTA (Over The Air) firmware update, but update with this steps will only available if the Acer already give update at their server base by country location. Please go to menu setting > About phone.

  2. Will I downgrade from KitKat 4.4 to Jelly Bean 4.2 if I factory reset my Iconia A3-A11?
    If not, how could I do that?
    Thank you

    • Hi, usually after we upgrade to newer version of Kitkat 4.4 with OTA at our Acer ICONA A3, there are nothing we can do to download to Jelly Bean or downgrade with OTA as well. The other alternative is using ADB or connected to computer which is not as easy as download from OTA (over the air) update. However, if you get problem after upgrade to latest firmware of Kitkat, then please consider to do hard reset or master format, because some old applications will need to reinstall for optimize with new OS or to make it compatible.

  3. Hi! I rooted my Acer A3-A10 using “Framaroot” and on that time it was still 4.2.2 Jellybean but When I Update it into 4.4.2 KITKAT I forgot to unroot it. And now I can’t removed the superssu application on my device because it is partially rooted. How can I reinstall or restore the genuine firmware (4.2.2) of this device. Please reply thanks

    • Hi, please try to download other 3th party applications to test your front camera like Google camera or Camera 386. When activate that apps, try to switch to front camera. If you front camera still not work, try to hard reset or reformat to factory default your Acer Iconia A3 tablet for make sure your camera hardware still fine or not. If after doing hard reset your front camera still not work, then it seem your front camera hardware get trouble and need to get repair from Acer authorize service center.

  10. I have an acer tablet A3-A20. I have a problem of nasty popup ads coming from nowhere. It opens new tabs in Google browser or Opera, Although pop ups are blocked. I had Norton premium security installed but it did not worked to stop them. Then I have tried many antivirus and anti malware programs but they show no threats and problem persists. After failing every thing I did a Factory data reset to completely erase all installed data and programs. Reinstall anti virus programs etc. After a while the problem came back opening new tabs showing ads and showing I am the winner of prize etc. Is my ROM infected or boot record infected …What should I do.
