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.

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.

1.after flashing you should reboot to recovery mode it will install recovery after that it will show g7102 logo that time imedietely remove the battery
2.then again reboot into recovery & click data factory reset & then reboot...
note:
1.try flashing with different usb cable because dirty flash can also cause this problem
2.and before this what was your stock rom before on your phone 4.4.2 kitkat ver or jellybean ver
3. and be sure you are flashing the correct rom of your region as per your phone (for example indian ver of stock rom are of two kinds one is inu version & the other is ins version) so pls check which version of the rom is supported by your region & your phone

help me, please...

Forgive my poor English, please.
I want to root my moto G5 plus. So I unlock bootloader and flash TWRP 3.1.0 directly.(Maybe it's a problem)

I cant't enter the system, it just into TWRP again and again.
And now, my computer concider my device is Moto Z2 Play, it doesn't show the internal storage.
Can I get some help in there, please?

I suggest to reboot from TWRP to bootloader, then fastboot flash the 3.1.1-0 version from the TWRP thread which shouldn't have this problem. Try not to use older outdated guides/videos/etc and read/search the current forum threads first to help avoid problems.

You can also flash the image from within TWRP as well.

Just ran into this problem earlier. Go into fastboot/bootloader and enter "fastboot continue". It'll reboot into system afterwards

thanks to everyone, i fixed this problem. I just flash NPN25.137-35 Stock Full Firmware in bootloader.

I finally fixed this problem by going into TWRP and reformatting the data to ext4 then a reboot and reformat the data back to f2fs.
