Automatically patch system.img for use with Hisense A9, adding eink features support For advanced users, check xda for pre-patched images.

To run the script on linux and patch your own treble based system.img you simply have to:

• Download a treble-droid based system.img you want to use
• Download and extract a9_system_patcher.zip from https://github.com/damianmqr/a9_accessibility_service/releases/latest
• Go in terminal to the folder containing unzipped files
• Run sudo bash patch_system_img.sh /path/to/system.img
• system_patched.img will be saved in the same directory, ready to be flashed

Flashing the resulting file is done the same as any other system.img (make sure your bootloader is unlocked! and you have disabled vbmeta verification by reflashing with fastboot flash vbmeta --disable-verity --disable-verification vbmeta.img)

• reboot to fastbootd using adb reboot fastboot (or any other method)
• run fastboot flash system system_patched.img
• after that's done, run fastboot -w
• run fastboot reboot and give it a few minutes

Default E-ink features Usage:

Single Press E-Ink Button - Refresh Screen

Double Press E-Ink Button - Open E-Ink Menu with settings for Per-App refresh modes.

These mappings can be easily changed in the E-Ink Settings app
