Changing dory bootloader images

~~ Changing dory bootloader images ~~

(Warning that messing up any of this process could potentially brick your device!)

1.	Dump your imgdata partition within Asteroid OS. This can be done with busybox's dd.

	dd if=/dev/mmcblk0p10 of=/home/ceres/imgdata.img bs=64

	Then pull imagedata with adb or MTP to your computer.

	adb pull /home/ceres/imgdata.img

2.	Download and compile "imgdata tool" from https://github.com/NVISO-BE/nexus_5_bootloader_unpacker

	Unpack the images from imgdata.img with imgdata tool, and modify as needed.

	./iunp -x imgdata.img

	(For a seamless boot into Asteroid OS, the splashscreen images can be found here: https://github.com/AsteroidOS/meta-asteroid/tree/master/recipes-core/psplash/files )

3.	Repack your image(s) into your imgdata.img

	./iunp -r imgdata.img boot.png

4.	Reboot into fastboot mode and flash your modified imgdata. A hard reset is required to see your changes

	fastboot flash imgdata
