Does anyone know how to upgrade the from the ICS bootloader to the JB bootloader? The documentation with the release is unclear on this. JB 4.3 will not run without upgrading the bootloader. Would I, for instance, be able to copy the u-boot.bin to the sdcard and run the following commands in an ADB shell?
[now the prompt will change from "$" to "#"]
cat /sdcard/u-boot.bin > /dev/block/mmcblk0p0
sync; sync; sync
