Onda v919 air dualOS is now perfect!

1. The main problem with the Onda v919 air dualOS tablet was that Google Play Services

and Google Play Store did not work with the original firmware in Android OS.

2. I followed the instructions in "2. The alternative method of installation without

having to re-install Windows" by mirek 190.

a. I have downloaded the latest version of PhoneFlashTool for Windows and installed

it on my PC. The installation included the dnx drivers.

b. I downloaded the mirek190_flash_tool_v1.1_Onda and unzipped it in a folder on my pc.

c. I downloaded firmware "20160729 International Firmware with Gapps and no chinese apps"

and unzipped it in a folder on my PC.

d. I copied the contents of the firmware folder to the subfolder "rom" in the mirek tool folder.

e. I shut down tablet from Android and re-started the tablet by pressing Power + "Volume+" + "Volume -"

until the yellow sign of "dnx fastboot mode" appeared.

f. I executed flash.bat from the mirek tool folder and connected the tablet to PC with USB cable.

g. I have chosen option "1. Dirty install"

h. The new firmware was installed and the tablet re-booted to Android with the Google Play Services

and Google Play Store perfectly working but no sound in Android (check it)!

Omit step 3 if sound works in Android.

3. I followed the instructions at the end of the post to upgrade the tablet's BIOS to restore sound in the tablet .

a. I downloaded and unzipped in the tablet's windows 10 the file "V919 air ch dualos_v117.zip"

b. I ran as Administrator the file "flash.bat" and Windows re-booted after the installation of the

upgraded tablet BIOS.

4. After the BIOS upgrade the sound came back for both the Windows 10 and Android OS.
