Elephone P8000 - Partition table screwed up - No /data

My Elephone P8000 was running Eragon 5.5 fine, then I wanted to flash visi0nary's kernel (_1014), so I used the method discribed (fastboot flash ...), and when I rebooted the phone, it just kept boot looping :'(
I can access CWM recovery still, but I can't mount /data or /sdcard, so it's pretty bad .... I tried to flash the stock kernel but it didn't change anything, I think my partitions are ****ed up !
Here is my partition table : i63.tinypic.com/2h3ztj9.jpg
When I try to mount /data with adb I get an invalid argument, and when I check "/dev/block/platform/mtk-msdc.0/by-name/userdata" with e2fsck, it says that the superblock could not be read or does not describe an ext2 filesystem ....
Please, can anyone help me ?
