I tried to install CM11 on my Nexus 10. But, I wasn't able to install the boot.img with fastboot (Rooted, CM11 flashed with Clockworkmod recovery):
[root@xx temp]# fastboot flash bootloader boot.img
sending 'bootloader' (5100 KB)...
OKAY [ 0.708s]
FAILED (remote: partition table update fail!)
finished. total time: 0.726s
The boot.img is from cm-11-20140405-SNAPSHOT-M5-manta.zip.
Any ideas, why this doesn't work?
