I bought a new never used Tab 3 for the intended purpose of using it as a universal remote. I wanted to strip it down and started right away with installing custom recovery, or at least I tried. No matter what I did I was not able to get Odin to properly load TWRP. It went through all the steps but I was not able to get into recovery other than stock.
Fast forward to the next day, I finally get it to work and somewhere in this process I somehow deleted or unmounted (I really am not sure) my efs folder/partition. If I try to reset deleting all cache and wiping everything including pulling the battery for a few minutes and flashing the stock ROM again I get hung up at the "SAMSUNG' logo. I have tried several ROMs and even tried using Odin to flash a new pit file with I found HERE. When I load both the pit file and my ROM into Odin it eventually says 'FAIL'. I can flash ROMs all day with no issue.
I can only assume that the error I am getting in recovery that says E:failed to mount /efs (Invalid argument) is my issue.
Adb is not really an option for me since I have little to none, more like none at all knowledge of using it. I assume since I have flashed several tries that USB Debugging is not enabled anyway and isn't enabling it key to using ADB anyway?
I have been at this for 2 full days searching everywhere and trying everything I see. I am at a loss and hate to think this new Tab is already junk.
Any help would be greatly appreciated!

So I should junk it then? I only paid $80 for this Tab.
One trial you may try to flash a Cyanogenmod based ROM see if it can write out the partitions else if no luck time to replace that item as mentioned
I have tried flashing CM and still the same issues.
I have since found out what my issue is (or at least 99% sure), I somehow wiped out my efs partition completely. So running a new pit file with Odin does nothing because the partition is gone.
This is fixable and easy for someone who knows shell, but I don't. So now I am trying to figure it out. It's a matter of pushing the 6 following files to the phone using the adb push [file] /sbin/ command using adb which I have done, now I need to figure out the rest.
e2fsck
mke2fs
parted
resize2fs
sdparted

you can't do that in the way you think, it requires disassembling the recovery image, making modifications and repacking then reflashing the image.
If you are using an older recovery, namely twrp, install a newer recovery , check @nels83 's thread for a "modern" twrp build.
You can also try one of my philz builds.
Being as you have been abusing Odin, you may actually have damaged your tab.
BUT if you are connecting to wifi without a problem then it's unlikely that you have damaged your efs partition. It's more likely an error with the recovery build you are using, probably in the fstab.

So, I recently acquired an Incredible, the second one I've owned. The first one I rooted, turned S-off and installed CM7 with zero difficulties, after that I rooted/flashed my Xperia Play CDMA with all the issues that accompany that device. (after the ease with which I modded my first DINC, the hoops through which I had to jump to unlock my bootloader blew my mind)
This DINC, though, refuses to clear user data. Even after multiple wipes via CWM, and multiple updates using the PB31IMG method, user data remains. Attmepts to preform a factory reset via HBOOT result in a balck screen with a red triangle and exclamation point.
I tried to install MIUI, thinking maybe a fresh rom would fix it, but it gets stuck at the room splash screen.
I've even tried recovering a clean CM7 install from my old incredible, but it gets stuck in a bootloop at the rom splash, same story trying to flash the .zip in recovery.
I've seen a few threads that deal with a few of these symptoms, but not the issue as a whole
Thanks in advance for any answers you guys have!
Cheers
I found a solution, finally. Admittedly, it was a bit drastic, but it worked, nonetheless.
I ended up disassembling both DIncs and putting the motherboard of the working device (with the smashed screen) into the device that was unable to format /data.
It was a bit touch and go for a bit, but my new DIY refubished phone is up and running.
Thanks for the help guys!
What error do you get? Can you upload the logs from /cache/ recovery after trying to wipe?

I'm still a bit of a noob, if you could point me towards some basic instructions on how to do that, I'll post a log when i get back to the house.
Last time I tried to logcat something in recovery, I nearly bricked my phone somehow.
Edit: It either gives me the red error triangle/exclamation point if i use HBOOT, or it gives me an error when trying to format the data partition on a recovery attempt.

Re-flash CWM recovery. The red triangle is a problem with recovery most likely. You can flash the latest CWM for the incredible from the app.
If that doesn't work then pull all the files from /cache/recovery location, use a file explorer app that can read it and copy it to the /sdcard location and upload it in a zip.

The red triangle happens when you try to do a factory reset from hboot wile on cwm recovery. If you really need to do a factory reset, you will need to flash to the stock recovery first. http://dinc.does-it.net/Recoveries/Stock_4.08.605.15/PB31IMG.zip Then if it works or even if not flash back to cwm recovery http://dinc.does-it.net/Recoveries/CWM_5.0.2.0/PB31IMG.zip.
The weird thing is, that even after flashing PBG31IMG via HBOOT I'm retaining all the previous user data. I've tried formatting the internal drive, using a few different versions of the image, even manual formatting of /data via CWM, which only gives me an error. the same error as when I tried to restore a nandroid from my functioning DINC.

So do i just make a .zip file out of the contents of /cache/recovery or is there something more to it?

That should be fine. Try to wipe data in cwm again just so it logs it.

I'm having the same issue, even after reflashing a rom or hard reset my system is as it was before, but most apps don't work. After turning on device instantly shows many errors such as error in com.android.phone etc... While trying factory reset in Recovery (5.0.2.0) the only error that logs is "no app2sd partition found. Skipping format of /sd-ext ". What can you advise? Please help, tomorrow I'm going to another country and in this moment working phone is very needed Device S-OFF Rooted HBoot 0.92

Same error if you flash stock GB sense and factory reset from recovery? You have the errors when booting and the apps are still there?
Sent from my Nexus 7 using Tapatalk 2
Thank you for reply, I solved reset issue by installing Amon Ra recovery. But the problem with apps still exists, it looks like system is restoring back up after reboot, I can do everything with system but after reboot it's like it was before with no changes made. Additionally, it seems that the problem is with emmc, just because when I delete EVERYTHING on it, after restart all files appear again!
I'm also getting an error when I try to manually format the data partition under >mounts and storage in CWM, I'm assuming that may be to blame for retained user data?
When I run show log after running only a manual /data format it displays:
6 black groups
32768 blocks per group. 32768 fragments per group
8112 inodes per group
superblock backups stored on blocks:
32768. 98304. 163840
The filesystem already has a journal,
tune2fs 1.41.6 (30-May-2009)
Setting current mount count to 1
Failure while running mke2fs
Error formatting /data!
mtd: succesfully wrote block at 0
I:Set boot command ""
I have no idea what that means really, or even if it's pertinent.
I had to remove the user info (owner data, phone number, etc) from my inc after canceling my contract with verizon. After about 25 different attempts to wipe it, I finally found something that worked (at least for me)
Tried running the RUU, could not reboot into HBOOT (version error)
Tried the RUU again, this time starting it after manually booting the phone to HBOOT. Got a little farther than before, but still errored out. Did not work. Disconnected phone, pulled battery, rebooted to HBOOT.
Factory reset in HBOOT got me stuck on the stock recovery screen. Battery pulled, could not boot.
Flashed CWM in HBOOT (by renaming to PB31IMG.zip), was able to get into CWM recovery.
Tried to flash the 2nd GB OTA in CWM, did not take. Every option I clicked in CWM gave me about 7 errors after sitting on the logo for a moment. Battery pull, reboot. Boots into CM9. >.<
Booted to my rom, saw about 300 force closes. Tried to reflash CWM from Rom Manager, got a bunch of force closes. Updated Rom Manager from market, reflashed CWM, and this time it worked.
Rebooted to CWM, wipe data/cache/dalvik, reboot.
This time I booted in CM9, but to the initial ICS set up (click next to begin, wireframe pic of Andy)
After skipping thru initial setup, I checked Settings>About Phone>Status. My phone number was removed, network is Unknown, and all my data was removed. Activation prompt appears on each boot.
Not sure if this will help, but worth a try. I think that the HBOOT factory reset is what cleared my data, and then I just needed to fix CWM so I could get back to a working ROM.
Yeah that's what I did in june except I just got service on mine but I would think that would help getting your data out forever. If that does not work I wouldn't know what to tell u besides grab a magnet. Lol

Hey guys,
Yesterday I noticed my My Note 8.0 looping on it's bootscreen. The screen was also flickering...
I haven't been able to reboot the device ever since... I have tried al the conventional ways...
First attempt was through stock recovery... it returned a fail error message when I tried to factory reset, wiping cache,... every option available gave some kind of error:
Code:
E: failed to mount /system (Invalid Argument)
can't mount /system (Invalid Argument)
E: failed to mount /data (Invalid Argument)
can't mount /data (Invalid Argument)
Device has always been rooted. I have done this soo many times so I am 100 % positively sure that I didn't do anything that would explicitly cause this kind of error. So I am sure that I didn't remove or alter any files in system or data directory.
But anyways... How can I fix this...
Device doesn't get recognized anymore by my computers...

You are rooted but no custom recovery? I take it you do not have nandroid to restore from? I have only had this tablet for a few days but imagine it being Samsung you can Odin back to factory stock if you don't have a backup or flash a stock image from stock recovery: http://forum.xda-developers.com/showthread.php?t=2289441

I was trying to address your issue with it not booting properly. Have you gotten it to boot up? Did you have a backup to restore from in CWM?
As for recognizing on the PC, I'm sure you probably have the correct drivers installed already. I have had the same issue on my S4 and have not found a solution yet so have been using a cloud service or yanking the card out to transfer. Have not tried it with the Note yet.
**Edit....I might add that most will suggest checking the USB cable and trying different USB ports (to get on a different IRQ) but none of this has worked for me in the past. Might be worth trying at least to make sure.

I'm gonna bring it back to the shop and hopefully, if I put up a poker face if they ask me about rooting my device :angel:, they accept it and treat it with warranty
For some reason, I really don't know what I have being trying...my tablet miraculously is working again!
Thread can be closed...
I am running a SM-P600 with Hyperdrive 4.1 and Xluco V3 kernel. I wanted to try out the new V4b3 kernel so i flashed it without any problems. Next i installed Xposed without a problem and flashed Xblast again without a problem. I went into Xblast and enabled the Visual Tweaks/Dark Halo Background. after rebooting the tablet, it started randomly rebooting (alot). so I uninstalled Xblast and rebooted then uninstalled Xposed and rebooted. This time after rebooting i am now stuck on the Hyperdrive bootscreen which i believed was a simple fix.
Boot to TWRP restored my current nandroid, still in bootloop. To make a long story short, i tried all my nandriods without success, fired up Odin v3.09 and flashed back to Stock NK1. Still stuck, but now of coarse stuck in the "Samsung" logo. so i rebooted in to Stock Recovery and "Low & Behold":
E: failed to mount /efs (Invalid argument)
I have been researching and trying to clear this error for about 3 days now. I really thought that flashing stock firmware (NK1 & NK2) made the most sense but i was wrong. Then I found something about using "Fastboot" but it seems that this samsung tablet does not support fastboot (please correct me if i am wrong).
Anyway i am at the point where my options are a complete destruction of the tablet (erase, wipe, format, mount, remount and/or flash) which i am not convinced that it would fix it and i would have an even larger problem.
My thoughts at this point are: this whole thing began with uninstalling Xposed so i would like to think my /EFS folder is probably still there and it just needs to be remounted. After all the googling (mostly smartphones affected by this issue) I have no idea where the SM-P600 /EFS folder should be mounted to (ie mmcblk0p3).
I would really, really appreciate any help, BTW: i do not have a backup of /EFS
I am sorry that this post turned into a novel but it is actually the short version of a 3 day trek of googling for an answer.
I had a similar problem with TWRP not being able to mount partitions, specifically the /data partition. It kept getting stuck at the boot animation. Looking at the partition in TWRP it showed the size of the partition as 0 MB.
Long story short I did about 7 factory resets before I started to get my partitions back. I think I read somewhere that it is a bug in TWRP 2.8.1.0 or something along those lines.
Try using older versions of TWRP.

On the website it said something about downgrading and adding the efs through your computer. Hope is not lost.
So I wanted to install a new ROM to my SM-P600. I had a CryogenMod ROM installed and wanted to go to Hyperdrive. I reboot to recovery and do the Factory Reset in TWRP. Afterward I go install the Hyperdrive ROM. However I notice that i'm getting the message that TWRP is "unable to mount /data" in the logs. The installation of Hyperdrive seems fine but I never boots.
How do I go about repairing the /data partition? I have adb and odin installed and working.
One thing I tried was going in to adb shell but I get this error when I try "could not load library "libc.so" needed by /sbin/sh". :crying:
Thank you for your help.

have you had any luck with your corrupt /data partition? i spent a couple weeks it seemed on my /efs corruption & it just needed to be remounted. i had to use CWM/PHILZ for adb commands. i know TWRP can do it but i had better luck with cwm + i was able to backup my /efs with cwm. if you are still stuck give me a shout
good luck

Hello. Need help is exactly what I need right now. Basically, I just tried flashing Oxygen OS from LineageOS, as I was just getting a little annoyed about how the updates were getting stupid and apps kept crashing. However, when I did this, it got stuck on just a sec when I was setting up. I then tore through the internet looking for how to wipe /data and /data/media with twrp command line. I found out about fastboot erase userdata. I used that. However, it wasn't just the casual wiping of the data where everything goes except the critical files. I mean every single little god damn thing got removed. I tried pulling /data and it said 0 files pulled. I was not happy. I managed to flash the rom but the phone won't boot. the worst part, I tried mounting /data on twrp and it said failed to mount data, invalid argument. So that was that. I then formatted to the original using the twrp format, (needed sighted help for that...) And it succeeded. Now however, I try mounting and it says no such device. 1, how can I mount data? And 2, how can I get a data partition that actually works with setting up and even the booting up of my phone. Yes, it won't boot.
Please help me, you don't believe how annoying it is to have a virtually useless phone.

PS, I was using stock bootloader and twrp recovery. Also, please give the answer of fixing in a command line method, I'm blind so getting sighted help would be rather annoying.
