Android 4.2 Jelly Bean Update for Allwinner A10 Devices: A Complete Guide



Android 4.2 for Allwinner A10 Firmware Download




Android is one of the most popular operating systems for mobile devices, such as smartphones and tablets. It offers a variety of features, apps, and customization options that make it appealing to many users. However, not all devices run the latest version of Android, which may limit their performance, security, and compatibility.

If you have a device that runs on an older version of Android, such as Android 4.0 Ice Cream Sandwich or Android 4.1 Jelly Bean, you may want to update it to a newer version, such as Android 4.2 Jelly Bean. Android 4.2 brings some improvements and enhancements over previous versions, such as:


  • A new lock screen with widgets and camera access



  • A new quick settings panel that lets you adjust common settings with a swipe



  • A new gesture typing keyboard that lets you type faster by sliding your finger over the letters



  • A new photo sphere feature that lets you capture 360-degree panoramic photos



  • A new multi-user mode that lets you create multiple profiles on one device (only for tablets)



  • A new daydream feature that lets you display photos, news, or other content when your device is idle or docked



  • Improved performance, stability, and security



However, updating your device to Android 4.2 may not be as easy as it sounds. Depending on your device manufacturer and carrier, you may not receive an official over-the-air (OTA) update for Android 4.2, or you may have to wait for a long time before you get it. Moreover, some devices may not be compatible with Android 4.2, or may have hardware limitations that prevent them from running it smoothly.


Fortunately, there is another way to update your device to Android 4.2, and that is by flashing a custom firmware. A custom firmware is a modified version of Android that is developed by independent developers or communities, such as CyanogenMod, AOKP, or Paranoid Android. A custom firmware may offer more features, customization options, and performance enhancements than the official firmware, as well as support for devices that are not officially updated by the manufacturer or carrier.


However, flashing a custom firmware also involves some risks and challenges, such as voiding your warranty, losing your data and settings, bricking your device, or encountering bugs and issues. Therefore, you should only flash a custom firmware if you are confident and experienced in doing so, or if you are willing to take the responsibility for any possible consequences.


In this article, we will show you how to download and install Android 4.2 for Allwinner A10 devices. Allwinner A10 is a system-on-chip (SoC) that powers many low-cost Android devices, such as tablets, TV boxes, mini PCs, and dongles. Some examples of Allwinner A10 devices are Ainol Novo 7 Aurora II, MK802 II, Mele A1000/A2000, Onda Vi40 Elite/Vi30 Ultimate, and many more.

Requirements and preparations




Before you start flashing Android 4.2 for Allwinner A10, you need to make sure that you have the following requirements and preparations:


  • A backup of your data and settings. Flashing a new firmware will erase everything on your device, so you need to backup your important data and settings before proceeding. You can use a backup app or a cloud service to backup your contacts, messages, photos, videos, music, apps, and other files. You can also use a backup tool or a recovery mode to backup your system settings and app data.



  • A fully charged device and a power source. Flashing a new firmware may take some time and consume some battery power, so you need to make sure that your device is fully charged before starting. You also need to connect your device to a power source during the flashing process to avoid any interruptions or failures.



  • A firmware file and a flashing tool. You need to download the Android 4.2 firmware file for your Allwinner A10 device from an official or reliable source. You also need to download the flashing tool that is compatible with your device and firmware file. In this article, we will use LiveSuit as the flashing tool, but you can also use other tools such as PhoenixSuit or PhoenixCard.



  • A USB debugging mode enabled on your device. You need to enable USB debugging mode on your device to allow the flashing tool to communicate with it. To enable USB debugging mode, go to Settings > Developer options > USB debugging and toggle it on. If you do not see Developer options in your Settings menu, go to Settings > About device > Build number and tap it seven times until you see a message saying "You are now a developer".



Steps to flash the firmware




After you have completed the requirements and preparations above, you can proceed with the following steps to flash Android 4.2 for Allwinner A10:


  • Extract the firmware file and the flashing tool that you have downloaded. You should see a .img file for the firmware and an .exe file for the flashing tool.

  • Start the flashing process by clicking on the Yes button when prompted by the flashing tool.



  • Wait for the flashing process to finish. You should see a green progress bar indicating the status of the flashing process.
