Hello ...
I have installed Android at Raspberry Pi3. I want start the Android in Recovery-Mode via Network. Then, I want flash a GAPP at the boot sector.
With ADB Commands I have tried this.
adb connect IP-Adr.
adb push c:\flash_image /sdcard/
adb push c:\recovery.img /sdcard/
adb shell
su
mount -o remount, rw /system
cp /sdcard/flash_image /system/bin
cd /system/bin
chmod 777 flash_image
flash_image recovery /sdcard/recovery.img
An Error appeard PIE.

How can I resolve this Problem?
