In the process of updating the Toolkits for Android 4.3 I came across a problem that many Nexus 4 owners also found, that boot and recovery images cannot be booted using fastboot. The images will boot but the screen is blank its not much use.
I found the fix for booting recovery images with a simple search but nothing on booting boot images so along with the help of xda recognised developer stratosk we found the fix.
To boot recovery images using fastboot:
fastboot -c “lge.kcal=0|0|0|x” boot recovery.img
To boot boot images using fastboot:
fastboot -c “console=ttyHSL0,115200,n8 androidboot.hardware=mako lge.kcal=0|0|0|x” boot boot.img
I hope this information could prove useful to someone out there.
