CM11: Nexus 10 boots forever My Nexus 10 boots forever. I did (according to the cm-wiki):


Root it
Flash Clockworkmod-Recovery with fastboot
Flash CM11 with sideload
Flash Boot.img with fastboot


Now my Nexus 10 is stuck at the boot animation.

Any ideas?



I tried to wipe dalvik cache in advanced Menu in cwm. When I afterwards choose "show log" I get the following error:

mount: mounting /dev/block/platform/dw_mmc.0/by-name/userdata on /data failed: Invalid arguemnt
W:failed to mount /dev/block/platform/dw_mmc.0/by-name/userdata (File exists)

May theres ist the problem?



I flashed stock rom, and this works like a charm. Then I tried to install cm again and twrp. But, twrp tells me, that /data can't be mounted. I tried in twrp (Advanced, Terminal Command):

# mount /data
mount: mounting /dev/block/mmcblk0p9 on /data failed: Invalid argument
Boot into recovery and get a shell (e.g. adb shell on the PC connected via USB). Then format the userdata partition:

mke2fs -t ext4 /dev/block/platform/dw_mmc.0/by-name/userdata


Afterwards, simply reboot and it should work fine.

The reason why this is necessary is simply (thanks to @utkanos in #cyanogenmod for explaining it): When unlocking the bootloader using fastboot oem unlock it erases all data but doesn't create a proper filesystem.
