Allwinner A31 based tablets (such as the Onda V812 or V972) currently offer great processing power and value for the price. These devices are still young products which receive frequent firmware updates, that are usually delivered thru incremental OTA (Other The Air) packages, downloaded thru WiFI on the "Update" application. Another update path that is specially useful for a Factory reset and full firmware image flash using Allwinner PhoenixSuit custom Windows application. This tutorial will explain the different steps to successfully flash a tablet based on Allwinner A31 processor.


Step 1. Download and install PhoenixSuit

PhoenixSuit Windows program is usually included with your tablet's firmware archive.
For convenience, we are including a copy for download here:

PhoenixSuit download

Older versions for archive:

Install PhoenixSuit by running the installer program PhoenixSuitPacket_v1.0.5.msi (the file name may vary depending on the program version) on your computer. The installer is in Chinese, but it's quite straightforward pushing next button (situated on the right side) until the installation completes. Have a look on our video below to see the installation process in details.

Step 2. Download firmware image for your tablet and load it in PhoenixSuit

You need to download the firmware for your device. Manufacturers usually provide firmwares on their website. We also hold copies to latest firmwares on our forum. See at the end of this article for references.

Once PhoenixSuit is installed, you can load your tablet firmware. Click on the Firmware button then Image button and locate the .img file on your hard drive corresponding to the firmware you wish to flash.

Step 3. Put the tablet in flash mode

This step may appear a bit tricky as it requires playing with the hardware button on the tablet. Allwinner describes the procedure in the screen below:

Basically you need to do the following:

  • Disconnect the microUSB cable from your tablet
  • Shutdown the tablet, either from Android shutdown menu, or by pressing the Power button for about 10 seconds. The tablet screen should be black when the tablet is off.
  • Press the Home button on the tablet, plug in the micro USB cable on the tablet, while keeping the home button pressed.
  • Onda_V972_flashing2_b

  • While keeping the Home button pressed, make short presses (about half a second duration each) on the Power button for about 10 times or until you see the dialog below on the Windows machine.
  • Onda_V972_flashing3_b

    Once the tablet has entered in flash mode, you should see the dialog below.

    Please click Yes button to allow Format mode.

    Step 4. Flashing the tablet



    Step 5. Restart the tablet

    Your tablet may start configured in Chinese, please check our video (at position ) on how to set it in English.

    The video below goes thru all the steps of this flashing tutorial.

    Has anyone gotten the error "pnpfelln error!" when connecting their tablet (Onda V972)? I'm assuming it's a USB driver error of some kind, but haven't been able to correct it.

    I've tried PhoenixSuit 1.0.5 and 1.0.6 under Windows 7 on 2 different PCs (HP and Dell).

    After loading the image into PhoenixSuit (Onda stock 2.0 or Kasty) , I plug in the USB cable and immediately get the "pnpfelln error!". Hit 'okay' on the error pop-up and it never seems to recognize the device (All the while holding down home button and pushing the power button per the instructions).

    I scoped the Onda bbs and in the translation there was a mention of using a different USB cable (shorter/newer cables) as well as making sure to use the port on the back of the PC vs. the front (I'm guessing for USB off the motherboard instead of a hub). Both of which I have tried...

    I get the same error each time regardless, unless it crashes the PhoenixSuite app, which it will do if I plug in the USB and then to open PhoenixSuit.

    Any suggestions would be welcome. Thanks!

    (This did seem like the best forum as the others were firmware version specific, if there's a better place let me know.)

    I tried a 3rd PC, this time from a powered docking station, with a new USB cable and it just worked as described. Yay!
