Unhappy [Q] N7 [F2FS] stuck at Google Logo BL Avail.

Hello guys, i have a problem with my N7 2012 WIFI Grouper, i flashed a F2FS Rom with F2FS TWRP 2.7.0.0 Rec. and every worked fine for 2 days, till this morning, i powered it this moring up and it stuck at the Google Logo. Access to Recovery is not possible, but i can boot it via Fastboot ... all Data is Lost even on the Internal SDCARD but i dont find any Mount SDCARD option, that i can copy the Data on it.
I hope that you'll can help me.

Here is some LOG of TWRP:

It looks like you have a NAND failure. There seems to be an epidemic of these NAND and corrupted bootloader failures in the first generation Nexus 7s as they approach two years of use. I found a used $50 32GB motherboard (or $35 16GB motherboard) was far more cost effective than Asus' $213 repair estimate.
