• Add this into device/teclast/x98pro.
• This has been tested with Android-x86 9!
• You may need to patch the kernel driver for the touch input by yourself! For this just apply my patch inside the kernel tree:

• You may want to add an other boot animation (code is commented), just select one from here...
• This tree has some example support for OpenGapps
• The system.prop modifies the volume stepping to 25...
• Netflix? Well, due missing DRM only com.netflix.mediaclient_4.16.1_build_15145-15145_minAPI19(armeabi-v7a)(nodpi)_apkmirror.com.apk works...

...just some commands...

repo init -u git://git.osdn.net/gitroot/android-x86/manifest -b pie-x86 --partial-clone
repo sync
source build/envsetup.sh
lunch

Add this device tree and now build it with m or m iso_img!

Add OpenGapps to .repo/manifests/default.xml (before the </manifest> tag) -> https://github.com/opengapps/aosp_build; an other quick resync...

repo sync

Then for every folder in vendor/opengapps/sources run the following:

git lfs install
git lfs pull

and with patches for opengapps/aosp_build#257...

curl https://github.com/cwhuang/aosp_build/commit/384cdac7930e7a2b67fd287cfae943fdaf7e5ca3.patch | git -C vendor/opengapps/build apply -v --index

Also make sure to comment the gapps support from the device tree in... Now rebuild it and enjoy! When you get uncertified errors (which should be fixed by the system.prop file in the tree): https://www.technobaboy.com/2020/03/07/how-to-fix-device-is-not-play-protect-certified/
