Pre-built package
- boot.img: Linux Kernel + Ramdisk boot - cache.img: Android Cache partition - emmc_appsboot.mbn: Fastboot bootloader - flashall.sh: A script to flash images over fastboot - persist.img: Android persist partition - recovery.img: Recovery image - system.img: Android system partition - userdata.img: Android data partition
Flashing pre-built binaries to eMMC flash-storage
Execute the fastboot script
$cd /path to prebuilt imagages folder $sudo ./flashall
The following should be displayed on ubuntu host:
"waiting for device"
Connect device to PC:
- Press and hold the fastboot button
- Power up the device, or press the reset button
