yo para solucionarlo solo he tenido que hacer el pase 2

restore the cache partition - wipe /cache from the Recovery (preferred - thanks forcefreak). If the size of the partition says <null> (when Printing partition info in 4EXT Recovery) connect your device to a PC, go into adb shell (look the link in my signature for adb setup) and type Code:
mke2fs /dev/block/mmcblk0p27
do not pay attention to the busy partition message, then
Code:
reboot recovery
Note that this option will format your cache as ext2 or ext3 type. If you are using ext4 just use the 4EXT Recovery to reformat them as ext4
