Hey all, as I was trying to factory reset under TWRP, it would not let me and showed,
E: Unable to mount `/sd-ext'
How would I fix this?

Our device does not have an sd-ext partition. Use the latest TWRP 2.6 and erase system, data, cache, and dalvik cache.

Ohh, I have been using TWRP 2.3
Thanks! I'll try flashing TWRP 2.6

After trying to wipe it in TWRP it says unable to wipe sd/ext

Sd_ext is just a partition on you sdcard that does not exist unless you have created one.
It's just stating could not format sd_ext because it's not there
Do not fret my friend, it still factory resets like it's supposed to

[Q] I've unmounted and reset and am now stuck. Help?

I've already looked through previous posts and there seems to be no avail.
From 4.1.2. stock build, UVDMD5, (I'm assuming, that's when I bought it)
I tried to flash 4.4 ROMS onto it, Both Gummy and Beanstalk with their respective Gapps.
It wouldn't work and I wiped and reset and odin'd in the original firmware UVDMD5, so it successfully led to the beginning phone setup ONCE.
Then, from stock, I figured why not root and flash the ROMS once more? and this time, the galaxy would not have it.
I odin'd myself after the roms failed once more, but now..
Now the phone is stuck at the SAMSUNG loading boot screen.
Everytime I odin in the UVDMD5 setup, it says it's successful but constantly stuck at the boot screen.
I can get myself into recovery but no options are available to me.
If I try to progress forward, the roms will not work and I realized what might've done me in.
Once the roms in the very first trials wouldn't work, I messed with the mounting to see if it would change anything(HUGE mistake I now realize)
I think I unmounted /data and /system and pretty much everything!!!
I'm in the stock recovery so I could pull .zips from the external SD and I've tried to put in Cyanogenmod Recovery so I could get to the mounting options,
but now everytime it says that signature verification failed.
Tl;dr: I'm an idiot and unmounted everything and now it's stuck at boot screen and odin doesn't work. PLS HELP!
ps: ignore the ageold signature

First flash the very latest Recovery with ODIN. You will need to put the phone in download mode to do that. Next, flash Root66 version of UVDMD5 via odin and then flash Rom of your choice via Recovery.

I've taken the root66 and finished odin'ing it in, but no success. It's still stuck on the SAMSUNG screen.
When I boot up to (stock) recovery, the first red messages that appear is
E:failed to mount /data
can't mount '/data' (invalid argument)
and when I go into >apply update from external storage and try to apply cyanogen latest recovery,
all it gives me is E:failed to verify whole-file storage.
There is no /data, what do I do?

Please flash CWM Recovery via Odin.

First of all, thanks for sticking with me for this long.
I successfully installed Clockwork with odin and I thought this would be the end, but
It successfully mounted /system and /external_sd but,
Error mounting /data!
Error mounting /sdcard!
I don't know what to do from here. Is there a simple fix?

Did you flash latest version of CWM ? If yes then try Factory Reset in the Recovery.

I did factory reset it:
. . wiping data . .
formatting /data . . .
Error mounting /data!
Skipping format . . .
Formatting /cache
Formatting /sd-ext
Formatting /sdcard/ .android_secure
Error mounting /sdcard/ .android_secure!
Skipping format . . .
Data Wipe Complete.
Is what shows up and still /data and /sdcard cannot be mounted. Anything else? I'm desperate.

Part 2: I tried moving past all that and tried to run the ROMS, but it goes on to tell me:
This package is for "d2tmo" devices; this is a "d2vzw"
what does that mean?

Can you manually mount SD Card in the Recovery ?
I'd not try any roms until this issue is resolved.

What do you mean by manually?
The external sd card can be mounted, I'm pretty sure it means that the internal sd can't be mounted.
How would I mount internal in recovery? the options says it can't mount /data and /sdcard

Try TWRP Recovery.

What? You flash tar files with Odin not zips, and are you using the PC version?

Did anyone ever find a solution to this problem. I'm having the same issue after doing a soft reset through the settings menu. Through Philz touch recovery wiping dalvik cache does not work and same error messages you receive come up when trying to wipe user data/factory reset through recovery. This is becoming really frustrating because I know there is a fix I just can't find it anywhere. Please help!!!!!!!

You need to debrick image and reflash/fix the corrupt partition on your phone. Go to the following thread. .http://forum.xda-developers.com/gal...a-unbrick-t-mobile-s-iii-qhsusbdload-t2904318 and if you follow exactly, down to the millisecond, as instructed, you will succeed, that is assuming your device is still able initiate into "download." mode and MOST IMPORTANTLY, you have your device specific debrick image. . If and when your device does succumb and is back online, give your utmost thanks to docholiday77.

can't wipe/data factory reset or dalvik cache..

can i ask ya'll a simple life saving question !?
i'm unable to wipe data/factory reset.. even dalvik cache.. phone restarts into recovery or just hangs at Samsung logo upon trying to recover from Nand backup where it just fails at the point of either kernel or data wipe to further go ahead and rewrite them from the backup itself.. could be partition error maybe!?
well i'm able to mount data, but then again fail to format, it just restarts the whole recovery again..
hence, i can't do any ROM flashing, nothing whatsoever.. any inputs!?
using Odin maybe i should just install the stock firmware .tar file n then try factory reset !? it would wipe internal SD i'm sure and maybe that works..
Help me out in this brethren plz, any inputs!? my phone's almost rendered useless..
i was using my fav DN4 ROM.. when i tried to replace my phone battery, it just got stuck on Samsung logo..

unable to mount data
I got same problem
in twrp I got unable to mount data
my battery get problem
then my note 02 getting stuck
I was using eclipse
what should i do

Unable to restore TWRP backup: "Failed to mount /system (Structure needs cleaning)"

Unable to restore TWRP backup: "Failed to mount /system (Structure needs cleaning)"
Chiron latest version of TWRP, LOS15.1 and 16.0
I wanted to revert to the backup I made before upgrading to LOS16. So I launch TWRP, press restore, select all partitions, and I get to the Data partition when it says "extractTarFork() process ended with ERROR: 255".
I try again, this time without restoring the data partition, and I get to the very end of the process before it says "Failed to mount '/system' (Structure needs cleaning)". I try to repair /system, it fails. I format it to ext4, no help.
Now I've stopped trying anything. The phone can't be turned off, it'll just boot to fastboot, so I've left it on TWRP.
Edit: Alright. Formatted data, wiped System and Cache, installed the latest nightly of 15.1, installed the version of GApps I wanted, booted up just fine. Tried the restore, and it made it all the way through, no ERROR 255, nothing, until the very very end, when it again failed to mount /system, Structure needs cleaning. Rebooting to system sends me to fastboot.
