Getting closer Method inline building modifying device/lge/hammerhead/BoardConfig.mk with: TARGET_KERNEL_UBUNTU := false adding TARGET_KERNEL_CONFIG := hammerhead_defconfig TARGET_KERNEL_SOURCE := kernel/lge/hammerhead and BOARD_KERNEL_IMAGE_NAME := zImage-dtb
I have a dtb kernel, now recovery is working. Ubuntu Touch still does not boot. Checking the installed-files.txt compared to the one coming from the prebuilt kernel it sounds like the only missing stuff now are /system/lib/modules/3.4.0-1-hammerhead/ libs.
