Is this phone salvageable? I have quite the odd problem. I have plenty of backups, so I'm not worried about fully wiping the Nexus S.
I was running CM9 Alpha 11 when I heard about the ICS 4.0.4 OTA update for the I9020A. I rebooted into my recovery to make a nandroid backup. That's when the problems started. Mounting /sdcard, /system and /data fail, but mounting /cache works. Attempting to mount to USB Storage gives a "Unable to write to ums lunfile" error. When I noticed that the backups weren't taking, I tried to reboot normally but encountered bootlooping. As a last resort, I tried "fastboot oem unlock" but it freezes. Battery pull gives "FAILED (status read failed (too many links))" on windows.
Model: Nexus S I9020A
HW Version: Rev 16
Bootloader: I9020XXKA3
Baseband: I9020UCKF1
Carrier: ATT
ROM: CM9 Alpha 11
Recovery: ClockworkMod Touch Recovery v5.8.0.2
Bootloader: Locked
Busybox: v1.19.3-cm9
Accessible: fastboot, adb, adb shell with #, busybox, and recovery.
Symptoms: Bootlooping, unmountable /sdcard, /system and /data, cannot mount to USB Storage, bootloader does not unlock.
EDIT: Found this unfortunate bit of news. Looks like I'll be sending it in for repairs and hoping they won't notice the recovery.
EDIT2: I found out that I can flash zip files through a roundabout method to mount /cache as /sdcard. Unfortunately, all I've been able to do is to flash recovery since system and everything else isn't mounted. I haven't been able to get ./flash_image to work. I've tried making the mounts executable as well as flash_image. My last option is looking for the "Android system recovery <3e>" in the form of a .zip and flashing that so it looks like my warranty is still intact.
adb push update.zip /cache
adb shell
mount /dev/block/mtdblock4 /sdcard

After this, you can use the recovery to flash the update. So far, I've tested going back and forth between ClockworkMod Recovery 5.0.2.0 and ClockworkMod Touch Recovery 5.8.0.2.
EDIT3: ./flash_image doesn't work. However, flash_image works because I have busybox installed on my phone.
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.

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
Thanks

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
Title says it all. a lady brought me her moto g and on the screen all it had was no command and the android with the triangle !. so i booted it in to the bootloader and installed a custom recovery. tried to mount the sd card so i could recover her data off of it and it failed to mount so i tried mounting /data and it wouldnt mount and it says /data directory doesnt exist. /system would mount and several others would mount. so my question is, is this phone f***ed or is there a way to restore the /data directory through fastboot flashing?
Thanks for your time
Anthony

Try and reflash the system partition and boot into android. Then look for /data. /data might be corrupted...
I am totally new to rooting, not sure what I've done wrong.
I started trying to root my SM-J727P by installing TWRP with Odin. This works fine, then I added the superSU v2.82 file to the device's microSD card. I went to install tab in TWRP recovery mode->select storage->Micro SD card->superSU.
Then when I try to flash it, a red message appears saying "Could not mount /data and unable to find crypto footer. Failed to mount /data (Invalid Argument). At the bottom it says "Failed to mount /system (Device or Resource Busy). Failed to mount /data (Invalid Argument.)
After this I read that I need to format storage.
I went to wipe->format data->typed yes and the same message appears, "Failed to mount /system (device or resource busy).
I'm extremely new to this so I don't really know what I'm talking about but do I need to disable dm-verity?
Any help would be greatly appreciated.

I now have manually mounted system and no errors showed, after tapping reboot system, the phone entered a bootloop. Not sure if this is supposed to happen or not and if it is, how long does it take?

This happened to me when I was doing my first root with samsung. What I did was completely start over with a new stock ROM and TWRP. Be sure you have all the right things ticked on Odin. What I had to do with my sm-j700p was un-tick auto-restart when done, and when the TWRP was done flashing, I had to remove the battery instead of wait for it to shut down. Then QUICKLY go into recovery mode by pressing the buttons after you turn it back on. Flash ROM. If I remember correctly, I was so good from there, but the timing with samsung when pushing the buttons apparently is EVERYTHING.
And making sure it is the correct TWRP file. I also made the mistake of picking the wrong TWRP file. Same model and carrier...different year of phone. Software version number is where it's at to get the best info.
Good luck!
so I was trying to flash custom rom and everything go just fine and then for the flashing repartitoner part my phone just restart itself for some reason after the flashing and I thought everything should've been normal but it's not for the part that I flash customrom.zip I started noticing "can't mount /data /system /system_root /cache (invalid argument) and I think it's easy to find tutorial how to fix them on youtube
here's what I found on youtube and tried
1.wipe everything (not working and can't even mount anything)
2.format data(yep still impossible it's just red and say "failed to mount"
3.change filesystem(yep still impossible)
my phone is samsung j7 2016 (j7xelte) or sm-j710f
here's the clip (of me trying every ways to fix the problem
sorry if my english is bad
this is the log I got from advanced > copy log
nvm fixed using twrp/orangefox terminal and delete /data /cache /system /vendor folder and then try to "repair partition" and now it says that it's presented now
