TWRP Restore Failed ATT GS3

Flashed the latest stable Carbon rom yesterday and decided it wasn't for me so this morning I rebooted to TWRP and tried to run restore. The restore failed and the only error i see in the console is
Code:
E: error opening '/data/lost+found'
I went ahead and did the standard wipe (which also gave the same error, though it did not say failed) and rebooted, assuming it would just throw me back into carbon, but it got stuck in sort of a slow boot loop. I finally got back into recovery and now I'm at a bit of a loss. I saw only 2 suggestions, one being wipe /data and the other to flash back to stock with Odin. I'm not against wiping /data if someone could could either confirm that it would work or tell me if it's possible to backup some stuff from /data to my external sdcard or pc.
any advice would be appreciated, thanks
also sorry if this is the wrong place to post, I didn't see where else it would fit, says I can't post in the GS3 troubleshooting area.
ATT Galaxy S3
TWRP v2.6.0.0

fixed
Ok, I'm up and running again. I ended up formatting /data through twrp after I found out i could copy files over to external sd through its file manager.
so in case someone else runs into this:
assumes you have a twrp backup on the external sd
1. move important files with twrp's file manager to sd card
2. format /data
3. reboot recovery
3. standard wipe
4. restore backup from external
5. reboot system and cross fingers

[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.

[Q] Bricked Ascend P6-U06

Hello there,
I made the mistake of wiping the internal storage using TWRP.
I am unable to enter recovery mode with the button hold options (tried all variations). The only way I was able to get into TWRP was adb reboot recovery. adb connection is now gone and the phone is stuck at the boot screen.
I can get a fastboot connection and the bootloader is unlocked. So I flashed the boot partition with a stock boot.img and the recovery partition with a stock recovery.img (even though I can't enter the recovery partition).
the phone never gets past the boot logo. Is there a way to directly flash a system.img vie fastboot, so that the device can be used? I am kind of stuck here.. read several threads for the past 2-3 hours, tried to reinstall TWRP as recovery but cant boot into it, etc.
I downloaded the B510.zip and was wondering if there is a way to burn an .img out of that and flash the system partition. But maybe that doesn't make sense at all.
Any help is greatly appreciated

update
Alright then, I managed to boot into TWRP!! a previous version worked.
it shows: Custom storage (498MB), Internal Storage (0MB), External Storage (0MB)
i am now proceding to install the zipped 510 rom from huawei. unfortunately i must have lost my microSD so i am lefti with sideload and otg.
sideload doesn't work because i can't find my device with adb. only fastboot seems to work, i dont know the reason but i understand its normal for my situation.
i only have an unpowered otg cable. from what i read that won't work, but I'm giving it a try and currently load the zip on a usb flashdrive.
do i understand correctly that the overall storage just appears to be 498MB? my partition table must be fairly messed up if that is the case. are there other partitions not shown by TWRP?
what do you recommend besides/instead of getting a microsd?
kind regards

update #2
I managed to mount the internal storage as mtp and copied the zip into the pictures folder, because i had no writing permission for the parent dir.
i tried to install, but the first time i got an error that cache could not be mounted. i cleared the dalvik cache and retried.
this time i had another error message as you can see in the screenshot.
adb still does not work, so sideload is not an option. i can also mount the custom partition but it is just under 500mb while the rom zip is 7xx mb
any help would be greatly appreciated

Resolved
I managed to solve it. Installed the paranoid android rom from the pictures dir. it was under 500mb and worked fine.

You cant install Huawei Firmware with TWRP! Only Repacked / Custom Roms.

Unable to mount

Hi
I have a HTC One M8 and it was rooted and flashed with cyanogenmod. Today my phone just died by itself so I tried to start it up again. what happend was weird, it got stuck on the boot animation. i tried to shut it of and on and it kept getting stuck on the boot animation. I got in to the TWRP (2.7) recovery mode and tried everything there. I try to factory reset it and I get failed. it just says Unable to mount '/data' and Unable to mount internal storage. I try to shut it of and now it says that I don't have any OS installed. Through guides I mange to transfer a new cyanogenmod rom to the phone in hopes of trying to reflash it. But again, when I try to flash it I get failed and it says Unable to mount '/data' and Unable to mount internal storage.
I don't know what to do, I'm stuck. Help appriciated. I don't know what more information is needed to able to help me.

so through a lot of searching, I think that my main problem is because i can not mount my data folder. Everything I do, I get the message E: Unable to mount '/data'. I look inside data and the folder is empty. I tried this "How to: Fix a corrupted DATA partition on the HTC One" on Android Revolution HD (can't link the site since i'm a new member) and it didnt help. I got stuck at the "mount /data" command. The whole folder seems corrupt. I read on some places that I should format it in windows manager but that doesn't seem possible. My phone appears as a "CD-device(F" on my computer and I cant format that.
This is my only working phone and I really need it to work. plz help.
I've tried dozens of unrooting guides but none of them seem to work because of my mount problem.

What carrier are you on?

Try to flash TWRP again. And update the version. Sometimes this alone will fix the data partition not mounting bug.

Hey, i just got the EXACT EXACT same problem! Did you manage to workout a solution for it? I've been reading all
day threads of the "E: Unable to mount '/data" problem, and i'm really really confused about what to do.. would be great if you could tell me how it went. :good:

TWRP fails to wipe or format data

Hi, I regularly flash new roms for our device to test them, so I'm using TWRP for a long time.
2 weeks ago I installed the stock oreo rom and the TWRP recovery via fastboot.
Yesterday I wanted to test ToxycOS so I tried to wipe everything. The log does not show any error but the system and internal memory are sill there. From the main page of TWRP, if I go to ''Install'' and then ''select storage'' it says that there are ~50000 Mb in the internal storage, and I still can see all the folders with the TWRP file manager.
I even tried to format data but the result is the same.
The device won't boot but the files are still there.
So now I can only dirty flash roms.
It never happened to me before, what can I do?
