Moderator Notes: I was asked to sticky this thread as it seems to be a recurring issue and a couple of fixes are in the posts.
Sorry my bad english am latin.
Hi guys first thread here and i need your help. Here s the thing, i was using my tf700, browsering, and the tablet goes off, i tried start up and a bootloop appears. So i go to Recovery (latest TWRP) and i tried to flash a ROM (latest crombi kk), like always i tried to wipe cache and dav bfore flash it but that proces seems to fail, and a couple of messages like unable to mount /data unable to mount /system appears, first time happening, i never had troubles with the tablet. So i tried to get fastboot mode and run the fastboot erase cach command (i read in a forum dat some guy did that and work for him), so i download the adb fastboot files, i connect the tf700 to my laptop (windows 7 64bit) and a installing drivers message and i wait and the driver that is called Transformer did not install, i dont know where to get those drivers, i found a file Asus usb drivers and bla bla but when i unzip the file i get 3 folders and no .exe or installer. So i tried to continue and i enter fastboot mode in the tablet and connect usb tablet-pc, and now another driver installing message appears, now is a driver called Fastboot, so i wait anda again the driver did not install correctly. So i continue and open cmd and tried the comman for erase cache, and only appears the WAITING FOR DEVICE text. i donw know waht to do, i also tried flashing again a ROM, bt only bootloop, trie again to wipe cache and dav but is only unable to mount /data. Any ideas ????

More likely your data partition got corrupted.
Try wiping it or formatting /data in TWRP to see if that helps? You will lose everything if you don't have backups.

i already tried that, wiping (cache, dav, system, ata, factoty reset) anything gives the unable to mount /data error.

You'll need to manually format it using the terminal in TWRP
Make sure data is umounted then run this command. Make sure you have charged it as well or leave it plugged in.
It can take a number of hours to complete.
Code:
mke2fs -T ext4 /dev/block/mmcblk0p8

You are welcome!
EDIT - somehow the format finally took.. after 5 or 6 reboots.. very strange
okay, i hate to bump this thread. but i have been searching for a few nights and i cannot find a solution. i am having the same problem as OP.
Essentially, my tablet was interrupted mid format. I believe my data partition is corrupted. I can access recovery/fastboot and the tablet accepts commands from my PC. i have TWRP 2.7.1.1 on the tablet right now.
i tried what sdbags said:

this did not work. i got the same "mke2fs 1.41.14 (22-dec-2010)" output, and then the tablet rebooted back into TWRP over again. (data was not mounted, i cannot mount it at all)
some more output from my tablets TWRP console:
Code:
e:could not mount/data and unable to find crypto footer.
e:unable to mount '/data'
e:unable to recreate /data/media folder/
updating partition details...
e:unable to mount '/data'
e:unable to mount internal storage.
e:unable to mount /data/media during gui startup
full selinux support is present.
e:unable to mount /data/,edia/twrp/.twrps when trying to read settings file.
e:unable to mount '/data'
is there another way to fix my corrupted partition?

I have exactly same situation
edit: after running this command
mke2fs -T ext4 /dev/block/mmcblk0p8
Click to expand...
Click to collapse
it prompt
Starting Path : /external_sd
Click to expand...
Click to collapse
and there is also button "KILL" when I hit enter it prompt : /dev/block/mmcblk0p8 is appereatly in use by the system: Will not make a file system here!
Any advice? (sry for being this big noob!)
Code:
adb shell
killall -19 recovery
make_ext4fs /dev/block/mmcblk0p8
reboot
Type in those commands via a usb connection to your device whilst it is in recovery.

No idea how when and after what exactly but the installation of stock rom started by itself after couple of reboots and couple of command i tried. (I had a file : US_epad-user-10.6.1.14.10.zip on my SD card

Probably a Bad Idea - you should unmount /data before formatting. Then it should also not hurt to keep the recovery running.
Unbrick my TF 700t
Accidentally, bricking my tablet
I try Advance and Terminal Command with TRWP at tablet, it did not work
but when I try with command from PC (desktop), it works like a charm. I was able to see internal storage
from that just re install Custom ROM. Thank alot to sdbag

After a long research I have found your thread.

sbdags help!
1) i dont know how to unmount data .
2) when i click advanced then terminal command it opens- Browse to starting folder and gives the file manager kind of view.
3) so i tried using adb on computer
the first three command work(i think but the third gives this error not enough space) .
please suggest a solution. thank you in advance
device moto g xt1033
i tried downgrading from lollipop 5.0 brasilian to kitkat but it wont go past warning bootloader unlocked screen. when i flash cm from twrp, it gives 3 errors
E:/ unable to mount '/data'
E:/ unable to mount '/cache'
E:/ unable to mount internal storage
then when i start it just keeps on loading on cm logo
should i create a separate thread for all this?

i am really sorry if the earlier comment came out as rude.
actually i did all of those steps, using the command terminal, using adb from pc but none of them worked, all of them had some problem
i had a spare sensation i was going to use as a backup.
earlier today it was running 4.4.4 , decided i would try 5.0.x clearly i made a mistake somewhere.
i have no access to /cache + /data
was using twrp 2.8.5.0
if i try and flash i get the following
e: could not mount / data and unable to find crypto footer.
e:unable to mount /cache
e:unable to mount /data
Seen a few simliar threads.... but am going in circles.
i can get phone into Fastboot USB and access if from the pc via adb. they i am lost.
Any suggestions gratefully received.
Hi,
i also have this problem. See my thread "[Q] Partition destroyed after power loss" below.
It looks like a problem with twrp2.8.5.0. on the HTC Sensation.
I've got the idea, to create new partitions on the device, but i haven't the time to do it. If you get any results, tell me please :=)

I started a RUU of stock and it kept sticking a about 45% ......
All i can get phone to do now is switch on with HTC in the centre of the screen with a Triangle in each corner.
Vol up/down make no effect at power on.
If i try and run 4ext install from pc , it reboots phone and fails on "writing recovery" by saying "remote: not allowed"
So im sort of stuck now ...

I can't see anything related to formatting in your log.
Please try formatting again and then run
Code:
adb pull /tmp/recovery.log
and post the full log here or on a paste site.

According to the log it formatted successfully, but maybe there was a problem writing back the changes. Let's look at the kernel log (please reboot and retry formatting again to get a clean log):
Code:
adb shell dmesg > dmesg.txt

Hello!
Recently I recevied "Encryption Unseccesful" message on my phone. I tried to restore backup, but twrp says: "failed to mount /data". So, internal storage is dead. Found this. But cant find "repartition" menu in the cwm.
Questions is:
1. Do I need older versions of cwm to repartition sdcard? (If you have one, please share )
2. Is there any ways of recovering phone?
Thanks in advance!
no, just go to TWRP, Wipe, Format internal sdcard

tried this, but I think internal storage is corrupted. Is there a way to use sdcard as internal storage?
you can use sd card for apps and other stuff, but as I knoe cannot be used for system files
I made 2 partitions on sd:
4gb fat32
4gb ext4
But I cant bind /data to this ext4 partition. Can you help, please?
What i did:
With TWRP's terminal:
Code:
mount -t ext4 /dev/block/mmcblk1p2 /data
- Invalid argument (dunno why)
Code:
ln -s /dev/block/mmcblk1p2 /data
- but on phone boot i receive same "encryption unsuccesful" screen.
Edited /etc/fstab - same result.
Files and mount after reboot turn back to its previous condition.
Also installed stock ROM - same message screen.
[/QUOTE]
I got advice that i must do this things with init.d scripts. How can I do this? Already tried "xda's app2sd scripts" but they works if phone completely boots in OS.

Why not? I want only mount /data on sd without booting in OS. Other partitions like /system surprisingly work right, because i can flash ROM (stock, CM), but always receive - "cant mount /data"
