Well, yes you can try to run fsck. you should follow the method i've outlined in previous post on how to boot the device into ftm mode. then you should be able to run fsck on the system partition (/dev/block.../by-name/system). you will need to run fsck with ext4 option, though i'm not sure if fsck is included, so you might need to download the android version of it and copy it to your device in ftm mode to the root directory change its permissions to 755. (remount / partition as rw)
It was still possible to go into FTM mode. I tried wiping and doing factory reset via the recovery but it didn't help.
I was above to recover from this situation only by loading new firmware (I loaded MC2-1130-0-10CN-A02 in .nb0 format (obtained on 4PDA.ru) using the SUTL LR loader (also obtained there) followed by the ROM from Needrom).
